Re: Ls1 Csk
CSK= Cold Start Knock aka piston slap
Alot of the ls series motor seem to have this problem to one degree or another. I have it mildly in my 99Z. It hasn't changed since the day I bought it, so I don't worry too much about it. FWIW, I run 10w30 mineral oil year round.here's a link to some good info:

If Wickeds is really bad or abnormal, and in warranty, I'd have to recommend he do something about it.
