Message: [QUOTE="Black 02, post: 1016428, member: 6916"] The HPOP is staying full. Well, it's about 1/2" down from the top. I thought maybe the Riffraff HPOP spacer was causing an issue, but it wouldn't manipulate oil pressure. The truck fires up after about 3 cranks every time now. Last night I went out and hooked the mechanical gauge to the top of the HPOP reservoir for s and giggles. I ran a long enough lead so I could read the gauge the entire time. Upon startup, pressure went to 25 psi at this location. I let it idle for about 30 seconds. After that, I gradually raised the RPMs up to about 2300. By this RPM range, the oil pressure was over 70 psi. Within 5 minutes of idling, the idle pressure had dropped to around 5 psi and the pressure at 2500 rpm was around 45-50 psi. After 15 minutes, the gauge barely moved at an idle. Really strange that the pressure would fall off that quickly. This is so frustrating. Its not like this was a $500 wrecking yard motor. Looking back, that's probably the route I should have went. [/QUOTE]
