I've heard some talk that some LS7s (as in the C6 ZO6 or the crate engine) have had oil pressure and/or valve train problems, but I can't find anyone who has actually had a problem or worked on an engine such a problem. However, the people talking about it should know what they are talking about.

I don't want to start unmerited rumors about what I think may be the best engine, pound for pound, in the world, but has anyone heard of LS7s with: low or erratic oil pressure, particularly to the top of the engine, or 2) dropped or loose valves?

Never, not once. Everything I have heard about that powerplant is right in line with your opinion there, Lee.

Any chance these rumours could have been started by Lada owners? :D

Lada owners? Not sure they would know what a valve is. More likely, Viper owners: must really honk them off to now own the second fastest stock American car.
