940 Rear Oil Seal Leak

[Rob]

I was just told that the rear oil seal on my 1994 940 Turbo ( 130,000
miles ) has a slight leak and that it is not serious but the seal will
need to be replaced at some point. They told me that replacing that part
requires dropping the transmission and will cost about $500.00US.

Does all of that sound about right?

Part of it does. I can easily believe that the rear main seal is leaking and
I'm sure replacing it requires dropping the tranny. $500 sure sounds like a
lot for that and you can live with the leak forever - I've been living with
a rear seal leak on our 765T for more than 10 years. It's a bit messy but
otherwise no problem.

You can try some seal conditioner - probably won't help, but it might. Cheap
and easy to try.

I would think this to be about 4 hours labor @ around $60.00 plus
parts. My local mechanic I think wanted $250 - $280 to do this job. I
guess your labor rate will dictate this where you live.

Actually, my shadetree mechanic friend who did mine must not have
seated it well, because I still get about 1 drop every 10 seconds. I
have to make sure this is not my distributor leaking. If it is the rear
main seal, we're going to drop the tranny and put in a new seal. This
time I am going to assist.

Thanks for the answer. I think I'll let it go and see what happens. $500
for dropping the transmission seems like almost a full day job. The seal
is probably on $25.

I'm trying that now.
