Car Forum / Volvo Cars / August 2007Volvo 940 Turbo Engine
My 940 Turbo Celebration (1998, 160Kmiles)) has a very noisy engine, and I think ineed to bite the bullet and get another one. (it was noisy when I bought it and sounded like tappets, but it isn't and it's gradually getting worse - suspect either a big or little end) The engine type is a B230FK. I've seen a couple of engines for sale on EBAY, but from older cars with slightly different numbers (eg B230ET). This is fine if they will fit, but I don't know which ones are suitable. Does anyone know which engines are compatible. I intend to use the existing turbo, manifolds, head if necessary (assuming the camshaft in my engine is matched to the ECU setup) and stick with the current injection system. All I'm really looking to change is the block. Any advice would be most gratefully accepted.

If the oil was changed at regular intervals, 160Kmiles is not a lot even for a turbo.

It gets worse as the oil gets hot, and the engine doesn't use any oil at all (which I would expect with worn rings or bores).

You need another B230FK or a B230FT. Both are identical blocks, the difference is the turbo pressure, the B230FT produces 165 (european) hp. B230ET is an older engine without catalytic converter and uses a different ECU.

If I can find an engine complete with a bigger turbo, will I get extra power without changing my current fuel system? Steve >>> My 940 Turbo Celebration (1998, 160Kmiles)) >> ...

Both engines use the same ECU (Bosch LH 2.4), they use the same turbo, same exhaust etc and were sold for the same price here in germany. The difference is the bypass valve on the turbo. Or more exacly the length of a rod between pressure capsule and bypass valve, mounted to the turbo. On the B230FT the rod is adjustable and has a different length. You could mount the capsule from a B230FT and get more power. Or you could buy something like the Dawes Controller (google) and get easily adjustable turbo pressure. I did buy that controller for my B230FT, it was fun to drive :-D Vitus (currently driving a B6254) SignatureVitus Jensen, Hannover, Germany, Earth, Universe (current) >>>> My 940 Turbo Celebration (1998, 160Kmiles)) >>> ... [quoted text clipped - 36 lines] > > Vitus (currently driving a B6254) Once again Vitus, many thanks. I have managed to find a suitable engine for sale (B230 FT) at a reasonable price and the work starts as soon as I get the engine home on Monday. I'm very grateful for your help.

You may have already checked this well, but look very carefully for noisy accessories before condemning the engine. >> My 940 Turbo Celebration (1998, 160Kmiles)) has a very noisy engine, and >> I think ineed to bite the bullet and get another one.

By the sound of it, I think it's one of the big ends - it is certainly louder around the sump than anywhere else. A bit anoying really. This is the 5th 740/940 i've owned, it's the newest by quite a margin and it's the only one that's ever given me any problems. The only saving grace is that I didn't pay a lot for it (bought it off Ebay) and it's quite a nice car in most other regards.
