I just had some motor work done, Timing chain Adjusters, and 2 lifters. When I got it back it was fine, quiet. Know the Valve noise is back, but only periodically. Wife took it out yesterday, 2 hour drive, no noise. Around town, noise, but not all the time. Anybody have any thoughts??? Thanx in Advance.

failing oil pump, causing low oil pressure at lower rpms?
Try a different weight of oil, or maybe some STP

 

Probably VTCs....check the FAQs

 

not on a 91 se, but his profile says 92 ?

 

I'm assuming he correctly identified his year in his profile, since he states he had his "timing chain adjusters" worked on. What year is it Upstate, it makes a big difference?
