piston slap
I have been driving FWD GM's for about 4 years now (all 3100 or 3400 cars) ... same problem with them ... i just make sure i remote start my car before i come out ... so the sound isnt that bad...LOL
But i know people with F-bodys and trucks ... who have the same piston slap ... and run bottles of spray every week ... and no prooblems
I guess it's hit or miss with fixing the problem
just my .02
