changing lifters...

[Konstatntin Bogach]

Hi all.

My 200tq 89 has terrible noise from lifters (BTW, I use syntetic 5-50).
I bought lifters and was going to do change them myself. Talking to my
michanic (good mechanic but doesn't have experience with Audis) I
mentioned my plans. He said that I might need to measure space for every
valve and adjust each lifter with shims. I found a lot of mail in
archive about lifters but I did not see somebody mentioned such
adjustment. Is it really needed?

Thank you.
