I was discussing this problem with a local mechanic. He said the Votec/LS engines have a problem with the oil pressure relief valve getting stuck. Usually they get stuck in the OPEN position but sometimes they get stuck in the CLOSED position. If CLOSED, then that might increase the oil pressure and display on the dash.

Now, I never asked him, OK, if that's the problem, what is the fix? Pull the engine? Or something less involved.

Any ideas?
