    Hi there I recently installed used Detroit s60 12.7 engine in my 97 fld classic, it’s a Detroit reman from 2012 and has around 300k miles on it(apperently) and came off from xpo day cab truck. My oil pressure when hot at idle is 26-27psi at 600rpm and when running 70mph at around 1500rpms it goes up to like 48-50 psi. Are these numbers still ok or should I get some things checked? I know my buddy with same motor runs 60psi hot at 1500 rpm. I am new to this motor so not sure if I am still in good range

    Your in spec. For a used engine. Might start doing oil samples to watch it. But your fine.

    I’m running the same pressure constantly as you posted. Normal.

    That’s normal pressure. Exactly what both my 12.7s have had. Before and after being overhauled.
