RE: 4000 quattro - leaking crank shaft seal FIXED
The correct answer from my original post was B: "I had the wrong part" for
the crankshaft seal. Apparently the OD of the seal for the crankshaft is
about 1mm larger than the seal for the camshaft. The ID is a little bigger
Watch out for this one. In-hand they LOOK LIKE the same part, but a couple
of listers have also informed me that some parts guys will insist that they
ARE the same part. I was told by my parts guy (second time around
unfortunately) that they are the same on the 4k.
These are the parts I ended up using:
Cam shaft seal: 026 103 085D
Crankshaft seal: 034 115 147A

Subject: 4000 quattro - leaking crank shaft seal
Thanks to the advice of many of you, I finally completed my timing belt,
pulley, water pump, belts, hoses and oil seals (cam and crank) job.
Unfortunately after running the car for about 3-4 minutes there was an 8
inch round puddle of oil on the floor directly under the front of the
engine. Now before you all jump to tell me that I forgot to replace one of
the bolts, I have to say I am pretty certain that I got them all back.
Here's what I'm thinking:
A: I did not properly seat one (or both of the seals.) I suspected the
crank seal because it went in with finger pressure and a bit of a snap.
Should the face of the seal be flush with the lip or countersunk a bit?
I'm hoping this is the case and I ONLY have to tear it all apart again and
properly seat the seal.
B: I got the wrong part. Can anyone verify that both the cam and crank on
the front of the engine are the same part number (026 103 085 D?) I would
find this rather unlikely since they are so very close in size but … an Audi
dealer quoted a different price for each of them?(not where I bought the
C: (Hopefully not this one) While prying out the old seals with a mechanics
pick and screwdriver, I damaged the housing such that the new part could not
properly seal. How much marring can be tolerated? If too much, can it be
repaired? I thought that I made a pretty clean pull.
Any feedback would be greatly appreciated.
And one last question: Can oil deteriorate the material of the timing belt?
I'd rather not do be doing this job again for a while!
Thanks a million,
