940 Distributor leaky

[Tony]

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.

The oil seal inside the distributor is available from many aftermarket
and internet sources over here. And there are instructions on the
brickboard.

This is a Canada only site, but I'm sure this is available a little
closer to your neck of the woods.

The seal is also available separately, without the 2 orings.

Brilliant, as ever the oracle on 940s. I didn't think that was
possible, it looked like some sort of metal seal because I couldn't see
it.

No signs here of kit suppliers but Volvoclub had a full description of
the spec and procedure, even tools and how to source seals. So I have
ordered 2 seals (1 for each car) on specification from a local bearing
stockist.

12idx20odx5mmT rubber coated double lip seals (£1.80 each).

Hopefully I can get the O rings from Volvo.
