CAUTION: Do not use metal scrapers, wire brushes, power abrasive

discs or other abrasive means to clean the sealing
surfaces. These tools cause scratches and gouges which
make leak paths. Use a plastic scraping tool to remove all
traces of old sealant.

NOTE:

The bolts are part of the valve cover and should not be
removed.
