Have 1986 Chevy K-30 with a 454. Oil pressure is running about 70lbs. Is that to high&could it be the oil pressure relief valve&where is said valve. Thanks

I don't believe there is a oil pressure relief valve, but there is a pressure bypass located in the neck of the oi filter mount. I would check to make sure that you have the correct oil filter on the motor.

While driving my chev 454 truck the oil pressure went to 0 psi

A leaking filter and oil pressure switch would cause the lack of oil pressure. Does the oil light work and does it go out now you have changed these parts. It only needs approx 8 psi to put the light out, the engine should run at approx 40 psi at 2000 rpm.

It should be located directly above the oil filter or possibly on the back of the engine block between the heads and behind the intake manifold.
