Exhaust manifold no longer made- option?

Thread rating:  |
Bubba - 04 Mar 2008 05:46 GMT I've found it nearly impossible to find an exhaust manifold for my '79 Ford Granada with the 250 ci six. Mine is cracked in two.
No major auto parts stores carry it and Ford says it's no longer made.
I've searched every junkyard in a 75 mile radius.
What are my options? I've heard they don't weld up too well. I've heard of "brazing". Does this work?
Thanks for any help....

There are several listed. These things CAN be welded too, it's just the welder needs to build a little jig to hold everything in position while it's being welded, which makes it a more expensive job to do right. Then it needs to be re-annealed after welding or it will crack at the weld.
I'd be a little wary of brazing something that gets that hot, but the braze will be much less brittle than a rough weld. --scott

Try http://car-part.com/index.htm
You can get a used manifold for about $40 to $75 plus shipping.
Good luck.

If I remember correctly there is no exhaust manifold difference between the 200 and 250. The only thing is that later versions like yours have the tubes for the air pump while earlier versions do not.
What part of it broke? The actual casting or one of the air pump tubes?
Maybe someone local to you can help you find one, try http://www.fordsix.com/ in the forums.... Or you could just buy a header for it ;)
big e lewis - 05 Mar 2008 14:36 GMT Regarding the lack of Fox bodies, and older cars in general in salvage yards.... I am the office manager of a salvage yard, and it is a shame that the older stuff is just being crushed. But with the price of scrap metal being at record highs, the yards don't have much choice. If the yard pays $180 per ton, as is the local price now, a 2 ton car or truck brings the scrapper $360. Now, the yard can sit on the vehicle, hoping to maybe sell a couple of parts off it, or strip and crush it. We rip out the motor/trans, which can be scrapped or sold to core buyers for nearly as much as we could get by selling to a customer. ( which also entails more time to pull gently, and a warranty that must be honored ) We can process the car in less than half an hour. With so much money tied up in an old clunker, that may or may not ever sell a part, when it can be turned into scrap doesn't make sense to keep around. Also, the aftermarket is producing more and more items, many of which sell for the same as we would have to charge to pay the yard guys to pull off the cars for the customer. As a car guy, and a circletrack racer, it makes me sick to see what gets crushed, but I know it must be done. I pesonally think that there will be alot of regret in 10 years by everyone that so much was crushed, but as long as the price of scrap stays so high, crushing will continue, and many parts will have to be bought new or not at all.

Bubba - 06 Mar 2008 06:25 GMT Thanks for the leads and help.
Through Car-parts I found one 58 miles away but the guy said it was very warped, almost 1/2". Buying from an out-of-state junkyard is a last-resort for me... not everyone is honest and I'll need lots of luck to get one shipped that is crack free and straight. I'd really like to see it in person, even if I have to travel.
The new header option is a good possibility. I called 'classic inlines' today and left a detailed message (as they said) but never heard back from them. I will see it there are others who could provide a header for this motor. According to the header websites, the 200 ci and 250 ci are not compatable, I think because of the starter location. I have the original A/C so that will be a problem too maybe as they say it will have to be re-routed.
As the last poster said, it's a shame so many of these old cars are trashed, but I understand. Wish they'd pull the exhaust manifolds off first :)
Thanks again and I will pursue these leads.

Thank you for the kind offer to look for me. Using a nationwide search with CarParts.com I found a NEW original equipment one. The guy claims it's brand new so I bought it today and it's coming UPS. I will post here when I get it. Thanks again to all. These forums are extremely helpful at times.

Bubba - 11 Mar 2008 05:47 GMT Got the new exhaust manifold and yes, it is NEW! I just can't believe it. The holes match a gasket I have so it should work.
I have a question though..... It has port holes in each exhaust port, they look like spark plug holes, about the same size and threaded. Must be for some pollution control stuff, which I don't have. How do I plug these? I could come up with my own ideas but there must be a correct way.
THANK YOU to all for helping me find an exhaust manifold. It was really wearing me down.

It was really wearing >me down. Your '79 should have an air pump or at least it did from the factory. That's what I was asking you about earlier, the tubes that go into the manifold for the air pump.
I'll guess it's just an NPT thread and you could probably just use a cast iron threaded plug from the plumbing isle... just put some high temp anti-seize on it first so if you ever need to remove them they'll come out.
thinking about it some more, maybe a thin coating of high-temp red exhaust mainfold RTV might be better than anti-sieze to just to prevent an exhaust leak.
maybe someone else will have a better idea....

Maybe, or they might be flare fittings. In either case plugs should be available, although flare plugs will be a little harder to find. I'd use brass rather than cast iron, but that's just my prejudice, either should work.

The existing cast iron manifold doesn't have these threaded holes, it's cast without them. There's no sign of an air pump or brackets for one. I guess if there was one, it's long gone.
> I'll guess it's just an NPT thread and you could probably just use a > cast iron threaded plug from the plumbing isle... I looked quite a while for a correct bolt today. It's the same thread as the spark plugs on my Yamaha 650- BP7ES. It's like a 9/16th with a fine #18 thread. I don't want to use spark plugs because everything looks so good and original, so I'll keep looking.

>The existing cast iron manifold doesn't have these threaded holes, >it's cast without them. There's no sign of an air pump or brackets >for one. I guess if there was one, it's long gone. Somebody modified something I would guess. The thermactor(sp?) system (the air pump) was added in ~1975 and as far as I know was present on the 6cylinder for the rest of its run (to ~1984). I haven't seen a 75 or later one in a junk yard that didn't have it. Either someone removed it and replaced the manifold with an earlier one or swapped the engine for an earlier one. Sadly, my 1978 shop manual does not have a picture of the exhaust manifold side of the engine.
Bob Flumere - 12 Mar 2008 17:07 GMT Doorman used to make plugs specificaly for this purpose. Check you local parts store.
Lee Richardson - 12 Mar 2008 22:41 GMT Chances are it is original. While I am not at all familiar with Ford products, I do know that back in that era 49 state trucks over about 6000 pounds GVW were exempt from emission controls, and were designed to be operated on leaded or unleaded fuel.
So while I can see someone going to the trouble to remove an air pump and all it's plumbing, I cannot see them going to the additional trouble and expense of changing out the entire exhaust manifold.
I purchased a new 1978 GMC heavy half ton pickup with a 350 gas engine that has no emission controls at all. No air pump, no catalytic conv., no EGR. It does have a preheat air cleaner and a coolant temperature switch for the distributor vacuum advance.

He's driving a '79 fairmont with a 250cid 6. Ford truck sixes are the 230 and 300 and a different engine family.
The '78 fairmont my parents had, had an airpump. The '82? mustang the neighbor kid had, had an airpump. Every '75 and up ford small six I've seen in the junkyard has had an airpump. My '75 maverick with a 200cid 6 had an airpump. My'73 maverick does not have an airpump, the change was in 74 or 75. The picture in the '78 shop manual shows the airpump, but it's a picture from the driver's side so only the pump itself is visible.
>So while I can see someone going to the trouble to remove an air pump and >all it's plumbing, I cannot see them going to the additional trouble and >expense of changing out the entire exhaust manifold. If you have an old manifold laying around it's cheaper and maybe even easier than screwing around with plugging the lines. Having worked on these engines with and without the thermactor system, removing it entirely and replacing the manifold is the best solution. The damn thing is always in the way. It blocks access to the front and much of both sides of the engine.

I should have mentioned that the new OEM exhaust manifold is tagged to be for a '75 Granada 250ci. It's official part # is D5DE-9430-CA. I wonder if the CA means california version which seems to me would have a higher emissions standard.

CA is just the revison as I recall... Ford doesn't change the year on the part number unless the part actually changes, so it would carry D5 in '79 if it didn't change.

Bubba - 19 Mar 2008 04:11 GMT I finally plugged the manifold ports because I'm installing it tomorrow.
The best I could find to plug the emissions holes were tractor wheel lug bolts at Tractor Supply. They were too long so I cut them shorter. The threads were a hair off. After 3/8" of screwing in they would start to cross thread. I cut them to 1/2" long and tightened them in until they bottomed out agains the tapered head. I used high temp threadlock also and they are very tight and seated well.
The farthest hole to the back was different. My old manifold has this one emissions port which is jury-rigged plugged. I found that a standard cast iron pipe plug fit this very coarse thread perfectly and I installed it into the new manifold as above. I don't know how they'll ever come out, but with my luck they will.
Thanks again for all the great advice. I still can't believe I found a brand new manifold using the recommended links.
Bubba.
