Correct Oil Pressure

[87M-GTE]

What should the correct oil psi be at idle fully warmed up? Mine will stay right about 10-20... Is my pump going?

That is a little higher than a normal worn engine.

TRSM specs:
Idle - 4.3 psi or more
@ 3000 rpm - 31-71 psi

Like Nick said, that is a little higher than what you normally see on a stock motor. Is your oil pump relief valve shimmed?

never rely on a stock gauge, especially oil pressure
