RE: the classic hydralic lifter noise ....again

Be very careful if you plan on retorquing the cam followers... The threads in in
the head and if you strip them, you will have some major problems on your hand
as Phil pointed out. Could be a bad set of lifters, or to ask the obvious....
Have you checked to make sure it isn't your vacuum pump making all of that
racket? In most cases, that is what it is and is VERY easy to fix. Follow the
threads in the list about "vacuum pump" and you should be able to figure out
what I am talking about <smile>

Subject: the classic hydralic lifter noise ....again 
 
 
        Well to beat on dead horse.....I experienced the classic hydraulic 
lifter noise on my 85 Coupe and decided to replace them all while doing a 
timing belt job. The problem is the lifter noise is worse now with the new 
ones in there. There is no noise while the engine is cold and warming but 
noise when warm especially at idle and low rpm. Any ideas what the cure for 
this would be? The lifters were stored properly (upside down) as far as I 
know. Should I perhaps retorque the cam followers again or try over again 
with a new set of lifters? This is the most aggravating Audi problem I have 
experienced ......
