Okay, I have had an oil issue for a while and at first I assumed it was the well pump so I replaced that but it turns out I had oil pressure, but there is no oil flow it goes to the filter and that's as far as I believe it gets. I'm not sure if the crankshaft is getting oil or not but I know the camshaft is not you can hear the dry lifters as the engine runs and the oil pressure gets up to 80 PSI. I did find that there was some college in the oil pump where are some leaves had somehow gotten into the engine. I have cleaned all that up, but I'm not sure why there is no oil going through the engine. I was wondering if anyone has any suggestions or recommendations?

Good afternoon,

This sounds like you have a clogged oil passage inside the motor. If you have that much pressure and no oil to the lifters, then there is a restriction inside.

The engine will have to be removed and disassembled and inspected to determine the issue.
