It ain't the relief valve being stuck-its the engine eating itself. When they changed the oil and it was cold it had 50psi (which is about 20 psi off what it should be) until it warmed up. If you watch the oil pressure gauge closely while Nick is revving--oil pressure actually decreases as the revs climb at one point. That ain't no relief valve--that's munched MAIN bearings. Relief valve sticking is wishful thinking--that engine's fucked. J.Rob
P.S. Any time I have a relief valve stick it is usually closed and we see 100+psi and start blowing oil filter O rings.
