I knew it was the filter or crossed lines

What type of cooler do you have now?

I have this setup its about 18inches long overall 3" dia but only 12 of it is oil.

On my engines the bypasses are plugged with pipe plugs. If I switch the lines no oil at all goes through. It would mean a ruined engine.

Well how about this,,,I am getting no flow to my filter and pulled a line to make sure flow is going to the outside(in arrow side) of my filter,it is. I'm using a purolater L34631. My oil pressure is good and have run the motor several hrs this way. I thought I was just overcooling the oil and bypassed my cooler and the filter was still cool after the motor was warm. I had water in my oil from high water pressure and may have to pull the heads. I took out the outside bypass on my block Gen6 and didn't plug. Now I read in a book that that will cause the filter to fill and then just bypass the filter entirely. This must be happening to me. I thought I followed the advice I got here but either got some bad or misunderstood. It's gonna be a ***** to get the bypass replaced or plugged on the inside motor!!!If I have to replace head gskts I can do it then.

Cool

The center bypass can be removed the outside bypass should be a 30lb..
