75 psi is normal for this engine. Did it all of the sudden go from usually 50 to usually 75?
That's pretty normal after the truck is warmed up. 50 psig is plenty for idle. The old rule of thumb is 10 psig/1000 rpm. That's kinda low for my tastes but we have it beat by a mile.iahemiram said:Jimmy...
Is your oil pressure still fluctuating? I noticed mine at 75 and 50 within a matter of minutes. Whenever the truck idles it drops to 50, but when on the move, it is at 75...
