new development. my high oil pressure has returned. not blowing any seals this time though. the gauge reads 80 at idle and pegged while running. if i shut the engine off and immediatly turn the key back on the pressure reads 40 and drops one pound about every four of five seconds. i replaced sending unit and nothing changed. im going to put a manuel gage on it tommorrow and see how it reads. if it still reads high i dont know where to look for a problem.
