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. |

Stu - are you checking the pressure reading at your gauge plumbed in by the pressure sender or the gauge in the console? I have a pressure gauge in the engine compartment similar to your setup.....my VDO gauge reads about 6 psi at full warm but the external pressure gauge is over 10 psi. I put that external one in after seeing your setup and wondering how accurate the VDO gauge is.... |
