[s-cars] Oops..sent too early (was cam/crank seal)

[David Kase]

True that.  But does the seal hold back any oil pressure?  I suppose
not, but if it does I would drive the car straight to the garage.

Thinking about it a bit more...

These seals are designed for a specific diameter.  If a seal is forced
over 
a larger diameter surface, the two seal lips will wear out in very short

time.  Not sure what this will do to the crank, but the seal will not
last 
very long.

The outside diameter is likely the same allowing for the seal to fit.
The 
problem is, I believe the cam sealing diameter is smaller than the crank

sealing diameter.  This would mean that there would be extra pressure on
the 
crank from the seal.
While seemingly not a big problem, this may cause the crank to develop a

groove at the sealing point.  Crazy?  I thought so until I had to repair
my 
crank on my 454 BBS.  They offer a thin sleeve to put over the crank
sealing 
service to repair this.  I would doubt this part is available for the
Audi 
crank.
I would suspect that an Audi crank would not wear like a 1970 American
crank 
but you never know...

Certified factory trained Audi master technician of 25 years. I bought
both, 
we agree that the cam seal is easy and he'll just do the crank seal
while 
doing the tb. He tells me yesterday he forgot to do the coolant T and I
blow 
it off thinking that's not hard to do myself.  Then today I'm going
through 
the trunk and find the thermostat and the seal, only it's not the cam
seal, 
it's the crank seal! He put the cam seal on the cranshaft, and said it
went 
on without a problem. I labeled them based on PN and he described them
to me 
over the phone.. He just grabbed the wrong one I guess.  What's the 
consensus on how long this will last before leaking???
