3	Timing Chain Tensioner Gasket NOTE: Ensure the left timing chain tensioner mounting surface on the left cylinder head does not have any burrs or defects that would degrade the sealing of the NEW left timing chain tensioner gasket.
4	Timing Chain Tensioner- Left Side WARNING: The timing chain tensioner plunger is under high tension and must be retained by using the tensioner retraction pin during removal or installation of the timing chain tensioner. Failure to retain the timing chain tensioner plunger may cause it to be ejected with intense force and cause personal injury. Procedure Reset the timing chain tensioner plunger using your thumb and EN-52234 Timing Chain Tensioner Retaining Pin or a 1/8" drill bit to retain the plunger. Compress the plunger into the body and lock the right timing chain tensioner by inserting EN-52234 Timing Chain Tensioner Retaining Pin or 1/8" drill bit into the access hole in the side of the right timing chain tensioner body. Slowly release pressure on the right timing chain tensioner. The right timing chain tensioner should remain compressed.
