I did a search and saw a few threads where people were complaining about their cars sounding like a diesel engine. But I never did see one where someone said what was actually causing it. Did anyone find out what's causing that and if there's a fix (aside from a new engine) for it? Mine has been doing it for a while and I'm getting a little tired of it.

If the noise goes away when warm its most likely piston slap..lots of info out there about that in LS engines...
