[V8] timing belts

[Ed Kellock]

Thanks for the info.  I was thinking (hoping) that the slack was probably
normal depending on where the engine came to rest in its revolutions.  I
will take heed of your advice.  I do not want any bad things to happen to
this car.
 
I have been telling people I got "another" V8, but really it is The One that
I have wanted for some time.  I may actually consider selling the 93 that I
got a little less than 2 years ago.  It's either that or the 1990 which is
paid for and in decent shape but not nice enough to  obsess too much about
it getting damaged.

Hi Ed, 
 
I just replaced the TB on my 2002 A8L.  When at TDC, the belt was taut all
around. When I turned the engine off TDC one side was very taut, while the
other was very slack...so much so that it could slip off just as you
describe.  I talked to a couple mechanics and they uniformly told me that
was normal and that is why belt slack is checked at TDC.   So the slack you
are seeing may just be normal and not indicative of anything.  
 
Now, as for those cracks...be afraid, very afraid.  I wouldn't drive it at
all with cracking...a snapped belt is no fun at any level.
