Car Forum / Volvo Cars / October 20051987 760 sedan with a b230f engine questions
I got this car, the title says it is a turbo model, and it seems that the engine was replaced with a non turbo one. I don't know if the car worked after the change and I don't know if they replaced the computer and anything else that should be changed with the engine swap. The little bit that I have been able to drive the car tells me that the engine , tranny, brakes, steering, etc is ok. The problem is that I connect the battery and that the engine starts fine and 30 seconds after driving it starts to shut down after that it only idles fine but when I try to give it gas it bogs down It seems that in those first 30 sec it is working in "limp home" mode. How can I set it that way to drive it home? The Haynes manual has me more confused. Is there any good manual online for this car? Any help will be apreciated http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=4576652025& sspagename=STRK%3AMEWN%3AIT >I got this car, the title says it is a turbo model, and it seems that >the engine was replaced with a non turbo one.

Check (and wiggle) all fuses, then use the OBD socket and read the fault code from socket 2 (Fuel Injection) and then socket 6 (ignition system). -Place test lead into socket -Turn on ignition -Press test button for more than 1 second but less than 3 seconds -read the binary flashes to read the code: *-------***-------* would be code 1-3-1 -Again, press test button for more than 1 second but less than 3 seconds. WHne the first code appears again there are no more stored codes. To erase codes: -First read all codes -Place lead in socket -Turn on ignition -Press test button for at least five seconds and release -Light should bo on for 3-4 seconds -Press test button for at least five seconds and light should go out. -Check for stored code again as outlined above to verify a 1-1-1 codes (no faults) Be aware that not all faults will cause a "check engine" light to illuminate. Also be aware that it can be difficult to isolate faults (see my recent thread(s) on my AMM problems.

It appears the turbo has been removed; the duct from the AMM goes right to the intercooler. The rest of it looks like a turbo model, though. I bet the engine is still an FT and the ECU is the original.

The eBay link that you provided shows a turbo. The symptoms that you describe are consistent with a blown turbo. Here's a photo of the engine compartment alone (from the eBay ad): http://www.theoriginalusedcarfactory.com/VOLVO/dsc0002.jpg The turbo housing and tubing is clearly visible on the left. AC  SignatureAawara Chowdhury, Shelter 107, Champaign, IL. That is the problem: the title. intercooler and air filter are the original from the car a turbo model. And no there is no turbo , it has a straight regular exhaust manifold. the number stamped in the engine is b230f (no t at the end) The air filter is connected directly to the intercooler with one of those hoses like a vacuum cleaner >> I got this car, the title says it is a turbo model, and it seems that >> the engine was replaced with a non turbo one.

(I don't know why it would work for 30 seconds - ours sure doesn't under those conditions.) You can remove the duct from the AMM (so it is still connected to the intercooler) and try blowing into it. You should feel a lot of backpressure... very little leakage. If it leaks find out where. Also wash that silly black ring off your face :-) If you don't feel a lot of leakage I fear the AMM may be bad. Wrecking yards are the most affordable source of that. Disconnecting the AMM should put it in limp-home mode. Mike > Okay - the symptoms are fairly consistent with a large air leak between the > AMM and the throttle body. (I don't know why it would work for 30 seconds - [quoted text clipped - 8 lines] > > Mike Looking closely at the photo it seems as if the inlet hose to the intercooler is not connected. According to the seller's "check" this is a dual overhead cam 5 cylinder turbo. The interior may be redyed burgundy but the "autocheck" outfit people are maroons. Well, for $400 I guess you get what you pay for. If the underbody stuff is anything like the tires, the car needs an awful lot of work. It could still be a flood damaged car even though an insurance loss wasn't reported. Bob SignatureThe goal when driving is to miss the maximum number of objects. That was my first work: coonect that hose, and the problem continues even if I disconnect the AMM. Somewhere I read that with the AMM disconnected it should work in "limp mode" I got it much less than the price I bid for , I could not buy a bycicle for that price. the little bit that works the mechanical seems to be ok There are at least two junkyards where I could go and rip out any part I need for the price of a song. I don't think I have to trash the car because a computer problem, or does it has Windows installed in the computer? :27:00 GMT, User <radietzno@spamioip.com> wrote: >> Okay - the symptoms are fairly consistent with a large air leak between the >> AMM and the throttle body.

The computers are plenty reliable, assuming yours wasn't wet. (It's by the passenger's right foot, on the side.) If it has the turbo ECU I don't know what issues there are in running with a non-turbo engine. I really like James' idea of putting a turbo engine back in; it puts so many things right again. The engines are pretty bulletproof (mine has never had the head or either manifold off in 230K+ miles and 20 years), so if you find a wreck that looks like body damage or interior condition put it in the bone yard you're in business. If you find one with a serviceable engine harness you can remove the engine and harness intact with the tranny, and drop a new one in within a single day... even for a real slowpoke like me. (You may have noticed the hood will even open straight up!) Nobody makes cars that easy to work on any more. Mike > According to the seller's "check" this is a dual overhead cam 5 cylinder > turbo.

[quoted text clipped - 7 lines] > > Bob That's not correct, it's a 4 cylinder single overhead cam engine, it's what all the 700 series turbos had. My advice is to find a turbo motor from a junkyard and drop that in, it's much easier than trying to swap all the other bits around and the car will work as it was intended to. >> Looking closely at the photo it seems as if the inlet hose to the >> intercooler is not connected.

I know it sounds like a huge amount of work, but in the 760 it really isn't. There is plenty of room to work, and the engine/tranny comes out with little drama. You should know the turbo ducts are shockingly expensive; the inlet duct is about $200 from Volvo! It also is hard to find in decent condition in a wrecking yard; the bottom turns to mush where the oil collects at the lip of the turbo. If you find one from an '88 or later, also buy the engine harness. The '87 has the notorious disintegrating insulation unless it has also been changed. The harness comes out easily with the engine, too. Just follow the ends to the large connectors near the battery and the A/C drier.

I will get the computer/wiring/AMM/Hell sensor/etc from a 740 1988 and replace it. all the insulation from the wiring in the engine bay is disolving so I have to replace it anyway if I change the engine or not.

You should check the engine to find out if it's the turbo motor or not, if it is slap a turbo in there, makes the car driveable, without it a 760 is a bit of a dog. The engine is a b30f (not 230ft) Is there any web info about somebody swapping engines converting a non turbo to turbo? That will give me an idea whgat to check. >> I got this car, the title says it is a turbo model, and it seems that >> the engine was replaced with a non turbo one. [quoted text clipped - 18 lines] >not, if it is slap a turbo in there, makes the car driveable, without it a >760 is a bit of a dog. The Volvo 760 introduced in 1982 was a completely new model, was produced with a 4 cyl Turbo, with a V6 engine, and finally 6 cyl Turbo Diesel The Volvo 740 series was introduced in 1984 to North America, 2 years after the Volvo 760 started on the market. The Volvo 740 is always equipped with a 4 cylinder engine, either normally aspirated (B230F) or Turbocharged (B230FT). The Volvo 760 was available with a V6 or 4 cylinder Turbocharged only. Aside from the engine and cosmetic differences, the Volvo 740 and 760 are similar cars and shares the same body, suspension, brakes and more. According to Volvo ads it is more aerodynamic than a Porshe 928, has better automatic climate control system than a Cadillac Seville, outhandles a Jaguar, etc... Now I know I have to find the computer and wiring harness from a 740gle >> I got this car, the title says it is a turbo model, and it seems that >> the engine was replaced with a non turbo one.
