If you are getting oil out of the front and rear main seals and/or around the oil pan gasket, you are very likely pressurizing the oil pan with combustion pressure. I had an old truck with a 350 and a bad vacuum advance, so I set the initial timing up a bit (so it wasn't lazy around town, you just couldn't floor it or tow or it would knock...I forgot and pulled a trailer with it). After towing with it, it started using 1 qt per 30 miles. It was coming out of the front and rear crank seals. When I tore it down, the top rings were all shattered into 3/4" to 1 1/2" pieces. Compression was blowing right past the rings and into the pan, the pressure was blowing out of the seals and taking oil with it. If you have ring seal issues, you'll likely have oil leaking issues. The only way to fix that is to tear it down, check the bores and re-ring it.

Passenger valve cover has a pvc valve -hose to a catch can. oil is coming from the grommet area of the PVC. The catch can has hot water in it. The driver side has a oil cap on it. Oil is pressurizing out around the cap. Oil is spraying all over the back of the engine bay coming out of both holes. Oil pan had condensation all over it after shake down drive. My first set up was breather filters in both valve cover holes. Oil comes out in idle Ran car hard up and down a private airplane runway. Car felt strong and just installed new C5 brakes and t56. Please help me
