Here's a lil' tip on getting the twist/push in breathers/grommets to seal....

Materials needed.. tube of black RTV, spray can of brake cleaner, clean shop rag.

Pull your breather off and thoroughly clean the valve cover and breather contact area with the brake cleaner.

Place a thin bead of RTV tightly around the perimeter of the hole in the valve cover and some RTV on the other mating surface of the breather. Carefull, more is not better on the RTV. Too much excess can land inside the valve cover(s).

Carefully push/twist in your breather.

You can wipe tightly around the breather grommet with the brake clean damp shop rag.

It will not leak and it'll will easily twist loose with minimal intended force..
