Re: Engine Still Knocking 4K q



David Thoresen was concerned about his engine still knocking.

Check the vacuum pump by removing it from the block.  Then reinstall it
without the cam follower.  If the knocking goes away you have oil in the
vacuum pump.  Carefully take the pump apart, clean it and put it back on
with the cam follower in place.  You'll be as good as new until the pump
gets oil in it again.  (usually about a year)
