If you have those drains plugged then it might be trapping too much oil in the top if you don,t have it vented some how. Ran into this years ago

I would take those screens out. A wise old builder from Detroit told me its like watching water run down the street and how it backs up when it hits the drain. I have never used them. Stock baffled pan ( Milodon) and a stock pump will take you far.
