I have a problem on a 1996 940 GLE Estate where the distributor on the back on the head is leaking alot of oil. My own 1995 car leaks a bit and I had priced a replacement, but this car has had a gunked up engine through no oil changes. Its all clear now but it has done alot of damage including the expensive distributor.
Volvo want GBP180+ for a new distributor (base plate thing), can it be refurbished or repaired? Eurocarparts can't supply it, and one local alternator/starter repair company didn't do distributors.
I'd even be interested in a distributorless conversion as even my 1995 car hesitates a bit (except for a few miles after the cap has been cleaned of oil), but can't find anything on the market. If could find the time and necessary technical info I would consider tring to design it myself. The microprocessor side is easy enough, but I don't know how to deal with spark energies, coils specs etc, aas this would have to be designed from scratch if using 4 coils instead of 1. I think you just need to demuliplex the spark trigger to 4 coils, based on the Crank sensor, and then block off the hole using the plastic plug used in the cars with the intermediate shaft disty.
