Default Woke up and engine knocking, What is it?

when I started 01 Trans am this morning I heard a light knocking in the idle but then it went away after it warmed up(10 mins), should I be worried?

probably piston slap. really common with those motors. nothing to worry about

but if id gets worse and continues after the motor gets warm then it most likely spun a bearing

if your neighbor keeps putting saw dust in your
engine id bet it will get expensive real quick LOL

naw im thinking piston slap too
ive got an engine that had piston slap and got 248,000 miles and still going

change your oil maybe that will help the lifter ticking

nothing you can really do other than a rebuild to fix piston slap
