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

    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.

    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?

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