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 |

when you built the motor, did you keep turning the crank shaft by hand, and specifically did it easily turn when you tightened up the case halves together?
There are pins in the bearings, if you have a bearing mis aligned, the pin wont fit in the hole...and the crank is really hard to turn all the way around... It will turn, but not easily... That will also mean the oil galley is blocked because the hole in the bearing is not lined up. Rich |

If the gallery was blocked wouldn't the pressure increase? Anyhow I will get the car on the lift tomorrow and check the suction pipe and have another look at the pressure relief valve. The engine runs great (except for the oil pressure) I guess I messed up somewhere along the way. |
