No oil pressure 351M
The quick version:
I have zero oil pressure. 0 when cold, 0 when warm. Needless to say I don't run it very long. I added a mechanical oil pressure gauge and it doesn't even push any oil up in to the tube.
The long version:
When I bought the Bronco the PO said it had a blown head gasket and that it was showing no oil pressure, and that he had just installed a high volume oil pump because it had no pressure. He said it still had no pressure after the new pump. I noticed the gauges didn't work at all so I was hoping once I got the gauges working it would show oil pressure. I never could get the gauges working so I hooked up a mechanical oil pressure and temp gauge yesterday, and as mentioned above it doesn't even push any oil up in to the tube for the gauge.
I'm looking for any advice or experience here. Are the 351M's bad about snapping oil pump drive shafts? Or stripping at the pump or distributor?
I did search, but all the serches came up low oil pressure rather than zero. :(
No fullsize right now, but acquired an uncut I could not resist!
