I would not pull the engine just yet, reading this last post, I understand that you have flow, but no pressure.Gmanic wrote:My friend and mechanics are thinking to pull the motor again and dye-check the oil pan.
The forward drain plug is still leaking despite new crush washer and silicone sealant.
Thinking the might be a crack somewhere.
He thinks it is an internal leak pushing oil into the oil pan, just don't know where it is coming from.
The bend up gasket is the only piece of evidence we have seen.
Thanks again.
Pressure is.. a resistance to flow, So if the by-pass in the oil filter adaptor is open, you will have no resistance.
Pull it off and put the old screen back in, see what happens.
also pull the pressure regulator under the big brass nut on the right rear of the case. If it is held open by FOD there is no way the pump can create enough flow to get pressure.
Are you indicating RPM while cranking? Tach drive is the oil pump gears. no tach indication no gear rotation.
OBTW, did your new oil sump gasket have the proper holes in it, and were they placed in the proper position ? they can provide a gap in the pump suction side, when the sump gasket is flipped the pump can't prime, because the pump is sucking air from the crankcase, rather than oil from the sump. To trouble shoot this, add oil to over flow the sump and cover the gap between the sump and case. If it primes the pump and provides a pressure indication, you sump gasket is installed wrong.
I'd pull the filter adaptor first.
