If the issue has been on going then you may need to pull the heads and replace the valve guides and clean out the secondary air ports on the head. Valve guide replacement is 6K+.

There have been a small amount of issues with the vent valves on the valve cover(s). They are cheap and easy to inspect and replace has they pop off of 4 clips on the valve cover.

6K+?? OMG, I think I just had a mini heart attack.
