What do you think???

You might need a vent and filter with boost. Meaning boost is causing the oil to blow out the pcv system.

I never had this problem before and I've been running it this way for over 2 years.

When it came out the filler cap were you under full boost or close to it?


Mine sprays out sometimes under full boost around the cap and valve cover, like the oil cap doesnt seal all the way

Both! It didn't matter if it was 10 in vacuum or 2 psi.

Pull the #7 plug and take a looksy in there.

Even if there's no smoke and we didn't get into boost before the oil leak?? It's not missing or even hinting that a piston could be gone. Could it still be an issue?

I would think that under normal conditions it could hold together, but boost could push past it.

IDK, I am just guessing too. Do you have any vents that are clogged or otherwise inoperable?

Under full boost would make sense, under vacuum idle ehhhh IDK

Not that I know of but I'm still checking everything. It's driving me crazy!

I am with Jake on this one... Is it a solid line from the valve cover (I am guessing) to the turbo? If so, that would explain the higher psi--which would cause the oil to leak or spray out of the filler neck, or any other loosely clamped fitting.

I would do the easy/cheap things first. Cut the rubber hose from the valve cover and put an inline vent w/filter...do a test run; Compression test...do a test run; etc.
