High Oil Pressure
I have seen all the posts on the oil pressure sensor failing and pegging out the oil pressure gauge. My gauge usually reads about 44psi. My question: Is there and condition other than a sensor failure that could actually cause the oil pressure to increase to 80psi? I know in the past there were always concerns about low oil pressure, but I can think of no mechanical condition that would send the pressure through the roof?

I'm dealing with this now as well. Mine finally went bad after numersous years of faithful service. I replaced it with the GM new number 12573107 and a month later, its dead again. I suspect its leaking as well since I can smell a slight oil burning odor too. I ordered the aftermarket PS308 which should arrive today. Will try to gen up a relocation tubing setup so that I won't have to pull the intake again after this. Wish someone had a simple extension tube with the right fittings on it already, like a stainless flex tube. Can't find anything so far.
