The use of sealing aids (aviation cement, copper spray and glue) is not permitted. The gasket must be installed dry. Failure to follow these instructions may result in future oil leakage.
CAUTION:
The cylinder head bolts must be discarded and new bolts installed. They are tighten-to-yield designed and cannot be reused.
NOTE:
Do not turn the crankshaft until instructed to do so.

CAUTION:
If one or both tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. Any cracks, tears, cuts or separation from the tensioner body, or permanent compression of the seal bead, will require replacement of the tensioner.
CAUTION:
Timing chain procedures must be followed exactly or damage to valves and pistons will result.

The RH and LH camshaft phaser sprockets are similar. Refer to the single timing mark to identify the RH camshaft phaser sprocket and the L timing mark to identify the LH camshaft phaser sprocket.
NOTE:
Lubricate the roller followers with clean engine oil prior to installation.
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:
If the engine front cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
NOTE:
Make sure that the engine front cover gasket is in place on the engine front cover before installation.
NOTE:
If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
NOTE:
Lubricate the new O-ring seal with clean engine oil prior to installation.
