It's time to finally put an end to the leaky bastage that is my 360. I think the culprit is pressure, not the seal itself. Now that the motor sees higher RPM and temps for longer periods, it's rather evident that the crankcase is building too much pressure and blowing out seals. When running at high speed for a while, I'll see the dipstick covered in oil, and the rear oil pan seal and back of the block covered in oil.
The info:
360 on propane, Edelbrock performer cam & intake, shorty headers
When I get to the garage tonight, the first thing I'm going to check is the PCV.
To the best of my knowledge, the black grommet at the back of the intake is the PCV. That needs to see a vac, correct?
Where else should I be looking on this beast?
