Default Breather Chamber (PCV) leakage

hey HT im having a leakage problem all over the oil pan, half shaft, and header near the cat and can really pin point the exact location, and i suspect its leaking at #10 in the picture bc i just changed the oil pan gasket. has anyone ever had a leak from there?

Not to common to leak there. It's just an O-ring on the breather box, everone will have one. The big question is, is your PCV valve stuck open or closed? Change it, it's cheap and get neglected. Question 2., do you overrev or abuse the motor? Your rings could allow a much more pressurized combustion pass around them that your breather can not handle (flooding with oil instead of draining into the pan). When the breather is off, flush it out good and check that your oil level is correct.

It really doesn't help if you cannot pinpoint the oil leak. I suggest you clean everything thoroughly so you are able. It may not be from there at all. You could very well replace that o-ring and the leak is actually from somewhere else.
