Well as the title says is all gone tits up.
I started my rebuilt engine yesterday and broke in the cam, today was supposed to be the first drive. I decided to check the actual oil pressure so I pulled the pressure switch and connected my gauge. There was no pressure even at 2k rpm. The pump is working but there is no pressure. Obviously the oil must be going somewhere, if the high pressure relief plunger is stuck open would this explain what's happening? Appreciate some help |

I get >60 PSI at startup with 20w50.
After 20 minutes of hard driving, it will drop to 20 PSI at (slightly high) idle. And it will drop to 10 PSI (where my warning light turns on) when the idle drops so low that it is about to die. |

Is that with the stock oil pump? I am honestly embarrased to say "I dont know". The 2.0L engine came from the PO of my 71 1.8L car. I built it up and paid meticulous attention to everything EXCEPT measuring the gears on the oil pump. It had a steel cover not the stock-like one. I did check it and it had no interference with the cam gear engagement that required modification. And that pressure is AFTER traveling 30 feet to the front oil coolers and back through 12 AN hose. I was able to get 35-40 PSI just cranking the engine with the starter before I fired it up for cam breakin and then I installed the oil coolers. |
