NOTE:
Identify the location of each push rod. Each push rod is to be installed in the original location to prevent premature wear.
NOTE:
Gently loosen the intake manifold to separate the silicone sealant from the cylinder block.
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:
To clean the sealing area, use silicone gasket remover and metal surface prep. Observe all warnings and cautions and follow all application directions contained on the packaging of the silicone gasket remover and metal surface prep.
