I have had my 1999 Z28 since new. My problem is that almost since day one there has been a loud squeaking noise from the timing belt, probably the self tensioner area. It has been into the shop, under waranty, twice for this problem both times they changed the belt and "lubed things up" (their words not mine). Still the noise continues!! As I get older it is starting to really get on my nerves. I was wondering if this is a common problem with the LS1 engine in this car and if there is a satisfactory fix?
Please help before the squeaking drives me right off my rocker.
