As previoiusly mentioned, the dealer replaced the OCV valve the first time, but they rushed the job and didn't properly seal the valve cover. I had to take it back so they could redo the valve cover. Two months later, the OCV was leaking again, only worse. So I went back a 3rd time and they replaced the valve cover, valve cover gasket and OCV. This was about a month ago. Today I noticed it leaking from the top of the valve. It only occurs when I bring the rpms above 4.5k. I'm about to give up on it.
