No oil pressure

[kyletm13]

We have a 428 Big Block Ford engine with remote oil filter/cooler, on a brand new rebuilt motor. There is no pressure reading on the gauge, but when I remove the hoses into the filter, I put them into a bucket and I get oil pumping while cranking. If I put my thumb over it I got the pressure. I hace tested the gauge and it does work. We ran it twice first 10 min then later (awhile) 15 min, The water temp went to 190 and help and the motor did not seize. How can we prove that the oil is getting every where
it needs to go.

Thank Bob Putnam at ERA for this diagram

Now have a look at it and make sure you have the same line orientation....There is a definite "in and an out" in terms of flow direction

If it helps, the oil should enter the filter through the ring of holes in the outer edge, and come out (and hence go back into the engine) through the central hole.
Check to see if your piping is correct - maybe all you have to do is swap the pipes over on the remote filter head.

The reason you may have no pressure is that if your piping is reversed, the anti drain-back valve in the filter blocks the flow of oil. Many an engine builder has fallen foul of this, so don't even think you are the first!

Thank You Gentlemen
My Father and I thank you very much. That was the fix as soon as we swaped them and fired it up 80lbs pressure it runs smoothly its music
Thank You

With 25 minutes run time, and no oil pressure, I would drop the pan and pull a couple main bearing caps for inspection if it were mine.

I highly recommend pulling the pan and looking at your bearings.

I completely distroyed a brand new engine by doing the same thing you did. Also, take off your oil filter and cut it apart and look at the folded filter material. This is dirty work but it is a lot easier than re-building that engine. Bearings are cheap.

Also, if you do find any brass, aluminum, or copper in your filter you will want to throw away your oil cooler too. I have learned this lesson all to well. You probably don't have any damage but it is sure worth it to check everything out NOW!
