Both.

Weird I put the cap back on, drove 250 miles yesterday and not squeaks or squeals. The fuel trims quickly returned to where they originally were.

no........the squeal is from air trying to enter the crankcase because of the vacuum pulled through the manifold.
That's what Dave said in his write-up too. So the potential oil leaking is not from gaskets blowing out but from being sucked in?
