Was the engine hurt before you changed the cam and lifters?

Does it still have non adjustable rocker arms?

Did you plot the rocker geometry?

Oil pump failure in an otherwise solid bottom end is unlikely.

I would check the stuff you changed. The oil band on the Morel lifters and make sure its lined proproperly with the oil galley in the lifter bore... some of those Morel lifters are .300 taller for use with small base circle cams and that will play hell with all kinds of stuff on a regular bs cam. Cam brgs getting chewed up during cam removal and installation is another big possible problem.

Engine was fine before changing the cam and lifters

I still have the stock rocker arms with a trunion upgrade

Yes, the rocker geometry is good

Tell me more about the "oil band" on the morel lifters. This is a topic I am not familiar with. The lifters were ordered for the LS2 specifically and have been used by many other members of both the corvetteforum, ls1gto, and ls1tech with issue other than a little additional noise.

The engine has been running since August and we have put 5000+ miles on it with good consistent oil pressure. Then yesterday we had NONE.
