Re: 1997 chevy lumina 3.1L valvetrain rattle/noise?
My wife drives a 95 with the 3.1 and I can tell you from our experience that if you use cheap oil filters (fram in particular) I could hear a slight valve train rattle, especially at cold start up. I went back to AC delco and the noise stopped completely. Also, has the timing set ever been changed? I ask this because we had a lesabre that had a badly worn timing gear and it had a valve rattle right before it failed. (gotta love the nylon teeth on those oem timing gears!)
