Had the valve cover gasket and the drive belt replaced on my '93 Saturn SL1. Noticed new noise when I started car and for a few miles driving. Mechanic says that valve lifters need replacing, and soon. I think they have been making noise for quite a while. How can I tell if they need replacing, and if they have been bad for quite a while, has that damaged anything else, like valves, etc. Also, I think maybe that there are two separate noises, the lifters and a new noise starting after the gasket and drive belt were replaced. What could that be? Help!!
Thank you,
Carolyn
Valve lifters make a kind of rattly knocking noise! which sort of follow engine revs.if they are gone you may need a new camshaft as well, best to do itr all at the same time and are sold as a kit.are you sure there is a new noise or are you just listening harder?

If removing more than one valve lifter (tappet), mark the lifters and their locations as they must be installed in their original bores.

engine is making a knocking noise that follows as you accelerate. if it is a lifter, what exactly is this and what damage can it cause... im clueless...what else could the problem be?
