Thread rating:  |
cfoughty@gmail.com - 14 Nov 2005 22:44 GMT I would like to have your opinions on this subject. The following criteria should be taken into consideration regarding your answer:
o Only engines within the last 50 years o Give preference to engines that get good MPG (v8's do sometimes!) o Try to use some facts! And give examples to justify. o Current parts availability (the cheaper the parts the better) o Reliability is highly rated o High performance is not that important o The vehicle the engine is used in can/does affect the ability to repair, so mention that if you could. o What did I leave out?
I know this asking a lot, and I give thanks in advance for those that are willing to help.
I will summarize and post the results back to this newsgroup.
Thanks,
Cy

No examples necessary. It's an opinion, not a debate.

Reasonably peppy and great access even in an A-body (which would actually be my platform of choice.) Everything still available for dirt cheap. Cast iron reliable.
Honorable mention - Volkswagen 1.8L gasoline engine, early type with CIS and mechanical lifters - for the same reasons. Loses points for accessablility as it came in FWD cars, also loses points for requiring too many special tools to work on. Still an awesome engine.
Honorable mention - Studebaker 259 and 289 V-8. Included just because I like 'em. No idea how difficult they are to work on as I've never done any more serious internal work to one beyond replacing manifolds and water pumps and setting the valve clearances. They just run. Parts availability is a minus however - everything is available, but you pretty much have to order everything.

(Actually the 144 cid version of the Falcon Six was the real 98-pound weakling, especially when coupled to the Two Flavor Slush Cone, er, Ford-o-Matic, whose gear selectors should have read L and O, for Lugging and Over-revving.)
Seriously, all the Slant Sixes were rightly honored for reliability, but I'd give the nod to their Ford counterparts for ease of what repairs were needed. A lot of old-timers thought that was the best engine Ford ever made, and fortunately they soon started making it in much bigger sizes, culminating in 300 c.i.d. for pickup trucks. I always thought setting the breaker points in a Slant Six in a smaller body was a bit of a pain on account of, well, the slant, and then you had the mechanical lifters to set.
(A 4WD crew-cab three-quarter ton Dodge that I once maintained at work presented the opposite problem: I was not big enough to get at everything easily from the outside and not small enough to just sit *in* the underhood cavern and reach 'way over to the engine... A stepstool and a backache filled the bill.)
Of course, none of these problems are all that big a deal even for the beginner, and not within an order of magnitude of getting at the rear plugs on some traditionally mounted GM vee engines, or doing almost anything to the dark side of almost anybody's *transverse* vee engine. Almost any single-underarm-cam inline Six mounted fore and aft in almost any American car built before what a friend of mine calls the "heart-lung machine era" of pollution-related engine controls is going to be pretty copacetic for the beginning mechanic, and most of them could take a fair bit of abuse and neglect before large hard-parts problem reared their ugly head.

Naw, ya cain't. The only difference in service access is the 170 vs. 225 in a '60-'62 Valiant or Lancer. The heater box is on the firewall, and clearance is tight between the bottom of the heater box and the top of the rearmost 5 inches of the rocker cover on the 225. It is possible to remove the rocker cover without removing the heater box, but it's a 5-minute hassle that doesn't exist with the 170, which is an inch lower.

Somewhere along the line the car had been bastardized and it had a later "super six" two-barrel intake on it; that car was surprisingly quick off the line and suprised quite a few people that thought they could beat my grandma-looking beater at the stoplight grand prix.
Some days I regret selling that car, but then again, the second time i replaced the transmission it was snowing...

Somewhere along the line the car had been [quoted text clipped - 11 lines] > transmission. the tourqueflight automatic was as bulletproof as the 225 6, > and the 318 V8 I can tell you exactly how it happened, this car was a learning experience for me. I bought it for the princely sum of $150 since it had no brakes, wouldn't start, had been wrecked into a parked car by the PO, and none of the accessories worked.. A brake job, some rewiring, new tires, an idler arm, a junkyard fender and an adjustment to the choke pull off later and I was driving, But someone had dropped a "reman" 225 in it at some point, as all that was original was the exhaust manifold - it had later style head, intake and carb. Whoever did it was a friggin' idiot; they left off the heavy metal brace between the engine and trans which apparently is important. (I didn't know it was even supposed to be there until I started looking for parts in the junkyard and looked at a few other cars.) They also patched the cooler lines with fuel hose. After I had the trans replaced for the first time, after the flexplate sheared on me, the fuel hose failed literally the day i picked the car up, with smoky results and also a good amount of slippage due to running out of fluid at speed. I was fairly annoyed with the mechanic that I'd paid to replace the trans... you would have thought that he might have brought this to my attention. Guess not.
I replaced the trans myself at the side of the road with another junkyard unit, being out of money at this point (I'd just graduated from college and hadn't found a Real Job(tm) yet.) Yes, at the same time I replaced the tranny cooler lines with hard lines. When this trans turned out to be DOA, I sold the car to a girl who had been admiring the car ever since I got it. She obviously had good taste in vehicles, her DD was an old Jeepster Commando so I knew it was going to a good home. Last time I talked to her, she'd hammered out all the dents, put a decent paint job on it, and had pulled the whole drivetrain for a real post mortem. Apparently above and beyond the missing brace, the root cause of the issues was the reman engine, which I'd ASSumed to be good since it ran strong and smooth. Here apparently there was a good 1/4" of crank endplay, explaining the blowed up flexplate and subsequent front pump failure. Once that was sorted, her boyfriend was apparently using the car as a DD with no problems. (IMHO he didn't appreciate just how good he had it, but that's another story for another time...)
Now I am retrospectively kicking myself, as in the neighborhood/circle of acquantances I had at the time, there was not only my Dart, but a '64? Valiant, a '65 Dart, and a '69 Valiant all floating around. The '69 I convinced my then-GF to buy as a DD, which despite the complaints of her mom was a hell of a car. I think she paid $1100 for it and all it needed was new front end bushings to get through PA's safety inspection. She drove that for a good 5-6 years with the only major repair needed being a rebuilt head, when she burned a valve probably by never having the valves adjusted. Only other issue with that car was it ate points, and at one point the stock Holley basically disintegrated interally and was replaced by a Carter. The '64 was pristine, but oddly enough also wrecked in the exact same manner as my car by its owner (and probably in a similar state of inebriation.) The '65 was for sale for a good price, but had a bad carburetor according to its owner. In hindsight, I should have probably bought a reman carb for a test drive, because IIRC the asking price was under $1K and it was almost as nice as the '64. (had my car had the stock single barrel, I probably would have bought it as I would have had a carb at my disposal. My GF wouldn't let me borrow the carb off of her car for whatever reason...) All were four doors, 225/904s and all but mine were in exceptional shape - keep in mind that this was in Pittsburgh ca. 1998 so a rust free car of that vintage was very rare. I would have been happy with any of these cars, but ended up replacing the '67 with an '84 Rabbit GTI instead... a good car in its own right, but certainly not as distinctive as an old A-body. Plus I had my '67 that could have been used for a parts car, with four brand new brake assemblies.
Also about that time I located a '67 GT hardtop in a local junkard in exceptional shape, with a 273/auto. I seriously considered buying it whole from the junkyard as a project, until one day I was there buying parts for my car when I found that they'd sold the transmission out of it, by flipping the car on its side with a forklift and cutting it out with a torch. I really liked the owner of the yard, but I bit back a few choice words that day...
sorry for the long rambling...

markansas859 - 17 Nov 2005 14:40 GMT tis okay, Nate, I grew up in a MOPAR family
one uncle had a 1956 Plymouth he drove till 1973, when someone ran a stop sign on him. he bought a 1966 Dodge Coronet new for his wife, and he replaced the 56 Plymouth with a 65 Dodge Monaco
another uncle had several Plymouth Furys, and a 1980 Volare, which he just sold 2 years ago
My dad had a 1957 Plymouth, a 1966 Dodge Polara, and a 1976 Dodge Aspen
I did it in style..... I had a 1973 Chrysler New Yorker Broughan in 1980, drove it a year, and sold it for what I paid for it
then was the 85 Plymouth UN Reliant, and more recently, girlfriends dad's 86 Aries wagon, which I sold for twice what I got it for 4 months earlier
and cumulating in a 1991 Dodge Dynasty LE
so, yeah, I have seen a few 225's, 318's 2.2 L, 2.5 L , 3.3L, and a 440
Dodge is in my blood...... :)

I had 480,000 miles on the original engine and original turbocharger, but junked the car when the manual transaxle blew for the fifth time. Every single one of the transaxle problems had to due with fluid loss. Some of them were due to slow leaks, others rapid loss. All in different places, and all requiring a new transaxle. (And no, I didn't buy cheap rebuilts, although I did do the rebuild _once_ myself. After that experience, I decided to pay for the next one.)

This is not true. The 300 cid six used in trucks was related to the much older big block inline six family that started in the fifties (or forties?). Another family member was the 240 cid six. The 144 cid, small block six, was related to the 170 cid, 200 cid, and 250 cid six cylinder engines. Family relations of this small six are still built in Australia.

The stock induction (and lesserly the exhaust) system on the /6 makes me want to vomit. A stainless or aluminized heavy wall tube exhaust and a good three two barrel carb setup or a sanitary and fixable FI setup would be a big improvement. Big, big improvement.
The other thing is there are few chassis I'd want to own that take the /6. The trucks, but they deserve a diesel.

The trucks, but they deserve a diesel. I would love to see a diesel conversion in one of the old Power Wagons, but for most of the '70s and early '80s stuff, MOPAR stood for Mostly Old Parts and Rust. Nevertheless, my dad did a diesel conversion (mainly for the hell of it I think) of a beat-up and patched up '78 Dodge 4WD pickup that was held together mostly with duct tape and Bondo. He dropped a 4 cylinder B-series Cummins Turbo diesel into it in 1986 that had about 10,000 hours on it as a prototype test engine. It was as nasty as a Redneck's dream machine could be: it had solid engine mounts, sounded like a bulldozer, and had a front bumper made from 3/8 inch steel plate a foot tall. Main problem was it was limited in top speed to about 62 MPH due to the low RPM of the diesel and the gearing designed for a 318. We kept that truck in the family for about 10 years, until my brother in law sold it to some Good Ole Boys out Pittsburgh way for $200 about 8 years ago. Dad went on to buy a brand new 1989 Cummins Dodge the first year they were offered, and still drives it.
C. E. White - 14 Nov 2005 23:52 GMT The easiest engine I have ever personally worked on was the Ford 1.6L "Kent" 4 cylinder. Second easiest was a Ford 2L Pinto Engine (the German built one, not the 2.3L Lima engine). Other easy engines were the 4 cylinders in Austin-Healey Sprites, Ford Vulcan 3.0L V-6, Ford 4.9L inline 6 cylinder. Worst engines - hmmmm Toyota Cressida 6 cylinder, Ford Taurus 3.8L, Datsun 280Z 6 cylinder, Audi 2.2L 5 cylinder., any Ford modular V-8, Lotus 2.0L DOHC 4 cylinder. In between - Ford 2.9L and 4.0L OHC German built V-6s, Mazda 2.0L SOHC 4 cylinder, Ford pushrod V-8s, Chrysler 2.2L SOHC 4 cylinder, VW 1.8L four cylinder, Ford 2.3L "Lima" 4 cylinder.
In general, push rod engines are generally easier to work on than overhead cam engines. Over head cam (OHC) engines with belts are easier than OHC engines with chains. DOHC engines are harder than SOHC engines. OHC engines with finger followers are easier to work on than OHC engines with bucket tappets. Inline engines are easier than vee style engines. Fewer cylinders are easier than more cylinders. In my experience the difference in complexity between the 1.6L Kent OHV 4 cylinder and the 2.0L Pinto OHC 4 cylinder were minimal. The 2.0L actually had fewer parts than the 1.6L, but you could work on the 1.6L with a couple of crescent wrenches.

The engineering on the SBC was excellent. The execution often suffered, with bad valve guides and seats in most stock engines, and some very Mickey Mouse head castings in the late Gen1 era. A blueprinted, balanced SBC built out of "good guy" components would last as long as any gas engine in its displacement and weight class.

It's my understanding that the blocks (except for special HiPo blocks) were a fairly "soft" alloy, making a ring job pointless - if the rings are gone, you need to overbore and buy new pistons. Also most had cast cranks while other engines mentioned elsewhere in this thread had forged in even the most mundane apps, with larger bearing areas.

Cast cranks in non-high-output applications are not necessarily a demerit. As Dave Blanton pointed out, the cast crank is often harder, substantially so, than the forged one. Aircraft people had a phobia about cast cranks because VW converters found cast, non-counterweighted VW cranks in direct drive propeller service would fail quickly. The VW engine crankshaft was not only never designed for direct propeller drive, they were putting the prop on the gen pulley end of the crank and either bolting the engine, sans flywheel, to the firewall and running a Vertex mag or putting it on spacers and driving an aircraft/tractor (same thing) mag by a long thin Gilmer type belt. I call this Mickey Mouse U. School of Engineering.
Chevy did cheese in using the two bolt main bearing caps in lower rated versions, but there is an aftermarket conversion that is even better than the factory four bolt setup. At any rate, Chevy (and Mopar) blocks have always been of generally lesser metallurgy than Ford blocks-but Ford then ruins the "advantage" by paper thin castings incapable of rebore. I think most of us rate this one as "a pox on all your houses" because sleeved bores are the right way to do things and no production iron block American engine has them.

I'm not aware of the need to use sleeves in either AMC or Studebaker builds... I've been told by people who should know that those are the two finest V-8s made when it comes to building a forced-induction engine that makes big HP numbers but is still reliable and streetable. Both apparently use high-nickel block castings as well, and I've heard from several sources that machine shops absolutely loathe being asked to overbore a Stude engine, as you can literally wear out a boring bar before you get done with the job.
Of course, neither the Stude nor the Rambler/AMC was manufactured in anything approaching the numbers of any of the Big Three, so apparently that capability is not a big selling point among the general American population... (why not? if i could buy one new, I'd be counting the hours until my warranty ran out...)
I'm curious as to the internals of a Toyota Supra engine, as I've heard the same thing about them (that they live perfectly happily with completely ludicrous amounts of boost) but I have no experience with them nor do I know how they hold up long term.

I think most any boring machine would use a replaceable tip such as tungsten carbide or some other popular cutting material. At any rate a sleeve is always a better way to go, particularly (from a heat transfer standpoint) a wet liner. I am no fan of dry liners because experience with dry linered 71 series Detroits shows "most people" will not take the time to get the clearances right and heat transfer suffers. Both sleeve and block suffer.
There are modern bore and ring materials combinations that are easy to do with liners but impossible in a cast block and that's another big incentive to go linered.

The old Supra/Cressida/LC DOHC six in the old Eighties ones was hell for stout, but it weighed as much as a small block Chevy or Ford for something like 180 CID. So it should have been overdesigned on the lower end. I have no idea whether they are cheaply available from the rice importers. I know getting diesels is like pulling teeth because the Phillipines and South Americans buy all the yards can supply. If you want a used Isuzu, Mits or Nissan diesel you buy a non-automotive core and convert it over.
Most of those Supras, and the Celicas that were the same car firewall aft, are dead of rust now. Their popularity with Oriental punk gang members hasn't helped their desirability either-like the gay hairdressers that bought Citroen SMs and rural retards fixated on certain GM two-doors.
On the street or in the water or the air, there is no CID limitation and we don't tax by displacement in the US. So although you may have the satisfaction of being able to say you have the highest specific output, you are not getting any advantage over more displacement. A reliable engine that has a good displacement to weight ratio and is compact has a lot going for it, something a lot of European engines do not-they are small displacement because they traditionally taxed vehicles on engine size, leading to such ridiculous things as the 700 lb DOHC Jag sixes made in 2.6 or some laughable size.

You'd have to have a hell of a liner to wet sleeve a Stude engine, anyway. The bore thickness on a good casting can be up to .250" (yes, you read that right) which is probably part of the reason they're so good for boost.
Or, I suppose, you could happily punch out the bore size and get some more displacement, assuming you could find suitable pistons. Which would not be all bad.

Liners are used in iron blocks. Mercedes diesels have them, there's probably others.

AAMCO 8825 N. Black Canyon Highway Phoenix, AZ 85021 (602) 997-6289
couldn't get it to run more than a few hundred miles between breakdowns. They also filled the floor with orange peels, mangled the electrical cable (computer controlled), and ruined the engine by not filling the radiator. I couldn't understand how a shop that claimed to have plenty of experience with this particular transmission could do such a bad job. Nor could I understand why such an experienced shop would visit an Renault/AMC dealer after they had my car to obtain photocopies of the transmission manual. That dealer later rebuilt the engine and replaced the transmission (they said it was ruined inside, and silicone RTV was in the valve body). By the way, I didn't choose AAMCO, but my manager at the time insisted on them rather than the dealer. I think he was later arrested for bribing a state official.

I beg to differ. I think you'll find that well into the 90s, Mopar Ford and Oldsmobile (OK, they only kept building the Olds v8 barely into the 90s) block metals were the hardest of any, Chevrolet by far the softest.

I was just talking to my machinist about engines the other day (he'd just finished up my newest 440 short block). He was commenting that my brand new cam was bent .002" and that he'd straightened it. I said that I was afraid that Mopar Performance was going in the pooper. He laughed and said, ".002 is NOTHING. You should see some of the Chevy stuff I have to fix before I can build the engine. Its actually better now than it used to be, the 'good' Bowtie blocks used to have things like lifter bores out of line so bad that individual cylinder valve timing would vary by up to 4 degrees, cylinder to cylinder. We used to degree *every* cylinder and then take an average to use that for the final cam setting. Or with roller cams, you could buy a box full of lifters with varying offsets on the rollers to degree in each lifter bore- it took FOREVER to set up one of those pieces of <expletive deleted.>" He went on longer. He's not a Mopar specialist, either and in fact most of his volume these days is building Honda engines. But Mopar is his favorite and he's quite prepared to give factual defenses for that opinion.
I have yet to find ANYTHING about Chevy engineering that is on a par with other GM divisions (Olds, Buick, and Caddy in particular, or the Northstar today), let alone compared to Ford and Mopar. The biggest shortcomings of the smallblock are the little lifter bores that limit valve lift rate, the short rods that give it a rod ratio worse than some ultra long-stroke engines like the 225 slant 6, tiny bearings, and the goofy stud-mounted rockers/pushrod oiling setup (which was sadly adopted by Mopar on the '92-up Magnum 5.2 and 5.9, but at least with AMC-derived parts including cylindrical pivots and not the directionless ball pivots that caused pushrods to need guides rubbing against them all the time).

I always got a kick out of his answers when all the other car guys-hard-bit blue collar types -asked him how come if they were so great all real race cars (drag and short track roundy-rounders to them) used Chevys.

I'd be stupid to deny that Chevy power is the cheapest to build. As a friend of mine used to say, you can buy Chevy pistons and rings in 5 sizes next to the cotton balls on the shelf at Walgreen's. Slapping one together will result in an engine that will run (after a fashion). The difference between slapping one together and really blueprinting one is tens to a hundered horsepower for a drag engine, though, and that's not trivial.
But the original quesition was asked so that people would provide their opinions on what was EASIEST to work on.

Steve - 15 Nov 2005 03:18 GMT > I would like to have your opinions on this subject. The following > criteria should be taken into consideration regarding your answer: [quoted text clipped - 17 lines] > > Cy That's easy. Right now, Big-block Chrysler v8s are incredibly easy to work on. Well, they always were, and flatheads were even easier, but the big Mopar v8s still have excellent parts availability and flatheads don't. You can build a big mopar out of a catalog, for that matter.
Somes specific reasons:
1) Waterpump- 8 bolts (4 on the water pump, 4 on the fan). And you don't even have to remove the A/C and alternator belts, OR the radiator. Just unbolt the fan and move it forward, unbolt the water pump, and replace it. And that's on any car that it came in from the factory, except maybe the ultra-rare 440 A-bodies.
2) Distributor right up front (and electronic in everything after '72 so you rarely need to service it anyway)
3) Lower block- Y-block design with a flat oil pan rail and flat oil pan gasket- easy to put together with no oil leaks.
4) No coolant in the intake manifold- change manifolds without draining coolant.
4a) one-piece intake manifold gasket/valley pan gasket. None of those goofbag "end pieces" that you find on smallblocks and that leak like sieves unless you hold your tongue just right while assembling...
5) Oil pump- located on the left front of the block. You can change the oil pump without dropping the pan. You can also change the oil pressure regulator spring in most cars without removing the oil pump from the block.
6) oil filter accessibility- right up front on the lower driver's side. Don't have to shinny under the car far, nor reach up past suspension components and obstructions.
7) So damn tough you rarely have to do any of the above anyway :-)

That's the kind of answer I like: facts to back up your opinion.
I had no idea that the mopar engines were like that. The only thing that I ever fixed on Chryslers were that damn starter. More of those starters went out than I can count.
What about any chrysler four cylinder engines?

One advantage to many Japanese engines is they can be had very reasonably used with low miles from Japanese pulls. Cars are parted out or deported in Japan young because of an inspection law designed to keep old cars off the road.
Honda engines are a mixed bag because though they are reliable they are apparently difficult to work on internally. Most are electronic now, as are everyone else's and a carb and distributor is not an option on most, unlike Toys where even relatively recent ones have that option if you can find it-there is a distributor with advance mechanism available so you can run without an ECM. Also, they turn the wrong way, at least many of them, which would be OK for a Corvair or Citroen swap, but kills any other idea.
BEcause of their light weight you would think they would be OK for experimental aviation. Apparently not-the Subaru and Suzuki-Geo engines are used there but not the Honda. Go figure.

Definitely a nice engine. Unfortunately the rest of the car did not measure up. I think the engine was the only thing in my K-car that did not need to be fixed under warranty (well unless you include the auxiliary drive belts as part of the engine). Too bad Chrysler can't seem to put two parts together without something rattling. It is still the only new car I kept less than a year. At least the dealership mechanics were good at their jobs - but then they had a lot of practice. I never had to have the same thing fixed twice which I guess counts for something. I wish I could have said the same thing about the last Toyota I owned.

The old Dakota would have been a really good work truck-bigger than a Ranger or S10, smaller than full size- if a diesel had been available. Real trucks to me just don't have spark plugs.

Who said anything about what it "looks" like? Looks are deceiving. It shared the same principal engineer as the slant-6, and that counts for a lot more than appearance.

> Ever work on some Honda, Toyota, or Subaru engines? A Mazda 4-cylinder put me off Japanese engines forever :-p But the worst have to be some of the GMs I've worked on. Chevy 2.0 in a Cavalier- Couldn't change the oil filter without taking the skin of the back of my hand, just adjusting the tension on the A/C belt was a nightmare, etc. Cadillac HT4100 took the cake, though: you had to have a puller to remove the PS pulley so you could get to the bolts that hold the PS pump onto the engine. If they'd just used a SPOKED pulley, it would have been no problem, but NOOOOOO. As people have said, a garden-variety Chevy 350 is a lot easier, but its still dripping with little bits of GM silliness that make it harder than other to deal with (the guy that decided starters that need shimming are acceptable should be slowly tortured).

The whole intake manifold has to come off, but then again I drove my '93 F-150 over 180,000 miles without having to remove the valve cover, and it ran well and didn't leak when I sold it recently (can't say that much about the chassis though). I pretty much picked right up where I left off by buying a '94 F-150 with 184,000 miles put on it by a little old lady running a landscape business, which was in nice shape and had 4WD, which my '93 lacked. Despite the miles, she had taken immaculate care of it, and it looked and ran like new. Looking through the service records and talking to her mechanic, I found a number of repairs in common with my '93, such as rusty brake lines, gas tanks, leaky pan gaskets, etc, but no work done on either the head or injectors, with the exception of the spray in the manifold fuel injector cleaner.
Another pain is servicing the water pump. Rather than bolting the fan clutch to the water pump pulley, they use a screw on hub that requires special tools to disassemble it.
Thanks Ford!!
C. E. White - 16 Nov 2005 00:03 GMT > Another pain is servicing the water pump.

I actually have a set of the tools (which are not just for Fords), but the my favorite local shop just uses a big adjustable wrench. Sometimes they have to hit the end of the wrench with a hammer to break the hub loose (just be sure not to go the wrong way!).
I have a 1992 F150 with the 300 inch six. In 14 years, I've never touched the engine except to change the oil, and plugs (once). It does need new plug wires. I'll try to get around to it in the next few years. Unlike other Fords I've owned, it hasn't even needed the throttle body or IAC cleaned.

Luckily, I have an old country mechanic nearby who can help me over those humps, but he is getting into the Social Security age bracket, and is slowing down his business. He spends as much time shooting the bull with his customers as working, but he is competent and honest with his work, so I can't complain too much. His $80 tool was basically a big spanner wrench. I will have to see how big an adjustable I will need. I brought a larger one since I did the water pump, but I think it is still too small. I will cross that bridge when I come to it.

Bret Ludwig - 15 Nov 2005 20:04 GMT Though not strictly a car engine (they will go into pickups and Blazer/Ramcharger types) the "Screamin' Jimmy" two cycle Detroit Diesel has a lot to recommend it. Mechanical versions are that, wholly mechanical, no electrics needed to run. they are fundamentally simple and do not have the high pressure pumps, lines, and other external paraphernalia that scares a lot of people off diesels. Almost all do not even have glow plugs or intake heater systems.
They are loud, very heavy, and by modern diesel standards a little thirsty. And they do require some special tooling. But I guarantee you will never have ignition, carb or intake valve problems!
Brand loyalists will note they were developed by GM, used heavily by Ford, and now a part of DaimlerChrysler.

And on top of that, the Cummins, Macks, Cats, and Perkins don't have superchargers, ridiculous gearcases for the supercharger and accessory drives, coolant leaks like sieves at the cylinder/block seal, and don't burn their own lubricating oil almost as fast as they suck down diesel :-p
Yes, the Detroits (and their "General Motors Diesel" predecessors, all derived from the same basic Winton Engine architecture as EMD 2-stroke locomotive engines) have had a long and productive life. But they were sortof the "cheap and common" engines, never the best available.

Do you mean "running backwards" as in proper reverse rotation operation, or running backwards as in the accidental backwards operation, taking air in the exhaust pipe and exhausting out the intake and usually catching it on fire?
Detroits can be set up for L or R rotation. There are some parts that need swapping depending on what side the head faces, which side the blower faces and even which end is the flywheel at. But same block, heads, crank, different gears, cam and balance shaft. They are very versatile, at least the inlines, but you need to figure out what parts you need.
Most other diesels are much more difficult to swap over if reverse rotation is even possible. But most four cycle diesels WILL run "backwards" after a fashion, often by accident, and it's a horrid thing. Smoke biillows out the air cleaner and a colossal mess results, at best. If not stopped in a very short while, of course, the engine seizes as the oil pump is turning wrong way. Detroits are unlikely to do this as the blower goes the wrong way as well and the engine does not start.
As far as Detroits being particularly cheap and nasty, they were the choice of union fleets because they were very difficult for the stupid or disgruntled driver to tear up. They were also popular as repower for fire engines because full power operation from cold was far less damaging to them than to Caterpillars or Cumminses.

Most small four cylinder automotive engines that were pre-emissions and electric rather than electronic controlled were easy to work on. A 1959 Morris Minor 1000 engine was unbelievably easy to perform any work on and to remove for a complete rebuild.
