Piston slap in Holden Monaro

Answered by Graham Smith · 10 Mar 2011

You'd need to have an experienced mechanic listen to the noise to determine if it's piston slap or not. The LS1 certainly rattled on cold starts due to piston slap, and it used oil, they were the giveaways to a problem with the engine. Yours could have some piston slap, but your description suggests it's not serious, and certainly if the engine isn't oil to any degree I wouldn't be concerned. The noise could also be a worn lifter, that's why you need someone with experience to listen to it.
