I have piston slap on real cold starts (very common for lots of motors these days due to low friction piston designs). I guess you could say that sounds a bit like a diesel. Over freezing outside and it's a happy camper. Smooth, quiet engine for the class it's in - unless you're really flogging it. Injectors are loud with the hood open, but it runs pretty quiet with the hood shut.

The bigger midsized class 2.4/2.5 liter 4 cylinder engines will of course be a little more refined and quiet, though most 4 cyl engines are still pretty noisy on a cold start.

Sure Wisconsin has colder temps than West Virgina, so why am I not getting piston slap? Darn it, got screwed again.

Should I contact one of the GM reps so I can have piston slap too?

Ha, must be this darn flash RAM. I'll have to go get a software update.

Durn engineers these days...
