I have two 89 spyders I want to sell. A red with grey interior automatic with 29,000 miles with the nice curved wood, I am going to do the 30K service, does...
There's a PN for the side output differential seals listed in the interchange list. What manufacturer or supplier do they apply to? Also, will these fit my '89...
I've added some pictures to the Photos section: Tech pictures album, showing the wear on the far right exhaust cam bucket. Any ideas on causes (maybe previous...
Interesting: given the potential for big problems due to broken or slipped belt, I guess the 1st thing I'd do is remove the cover over the belt and see what's...
Jim, Fuel pump circuit? The leads to the pump are exposed to corrosion and the ground is via straps that connect to the chassis. A drop in fuel pressure...
Hi, I had strange behaviour similar to yours, from time to time. Back fires with an engine stalls. I've finished checking the ignition distributor adjustment, ...
Jim, On the carb engine rotating the distriutor changs the spark timing, on the f.i. engine rotating the distributor only changes at what point on the arm of...
Yes, I spent a few time before checking the distributor on my 430. But the reason was simple: that was something I did not check after having bought the car....
My 87 425i has two(2) a/c condenser. The main is between the radiator and the intercoolers as one one expect. The second is 4 ft long, 3 inches high, 2 inches...
Ed, My '89 Spyder has this same secondary condenser that is, yes, beat to sh*t. This set up from my meager mammory is this is known as Series II. It was...

Thanks Brooks. I indeed did find the diagram for it on CD#1 of the compendium. Yuck - what a monstrosity and with zero protection the way it hangs down. How...
My 430 has it as well but I thought is was an oil cooler ??? Regards Terry _____ From: BiturboZentrum@yahoogroups.com [mailto:BiturboZentrum@yahoogroups.com] ...
Alexis, The cam boxes are on the engine I have not removed them. All I can see is the cam and the buckets - one exhaust one intake. Which is the exhaust which...
Interesting. Why don't you just buy a Biturbo in good shape for $5,000.00 and pocket the extra $2,000.00 to redo the interior? Haha. Alan '89 Spyder...
... Is this an 18 valve engine? I do not know anything, but since there are two exhaust valves for each intake valve, I would expect there to be two exhaust...
Facing the engine, the exhaust cam lobe is first on the left side of the block. See picture of this head under: photos; Tech pictures; right side head. (In...
This sounds like the automatic transmission cooler, and added by a prior owner. Is this connected to the engine oil system or has an automatic trans been...
I have a 1987 biturbo i- 2.5 l injected. The car started missing which sounded like it was on one cylinder when cold but disappeared after a short while. I...
