oil pressure woes - help!
Posted: Fri Apr 14, 2017 5:31 pm
I've had an annoying leak from the pump cover of my oil pump for a while now so today I removed the cover and fitted a new O ring.
I restarted the car and raised it back up on the lift so that I could inspect the pump for signs of leaks - I must have had it running on tickover for 2-3 minutes.
When I dropped it back down to turn off the engine I was horrified to note the oil gauge on zero.
I removed the plugs and spun the engine but could still get no pressure. I then removed the pump cover and pressed vaseline into the pump vanes the tried again for a long as I dared - still no pressure.
What has gone wrong? The fact that the car started and did not prime the pump makes me think that the pump is 'bad'. I'm now thinking that perhaps the new o ring is too thick causing a gap between the plate and the vanes in the pump - is this a plausable explanation?
Can anyone make any suggestions?
Is it possible that running the engine on tickover has caused bearing damage?
I now feel inclined to buy a new pump then go from there.
