NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.

NOTE: For additional information, refer to the exploded view under the Assembly procedure.

Inspect the VCT solenoid seals and the spark plug tube seals. Remove any damaged seals.
- Using the VCT Spark Plug Tube Seal Remover and Handle, remove the seal(s).





76. Using the Strap Wrench, remove the crankshaft bolt and washer.
- Discard the bolt.





77. Using the 3-Jaw Puller, remove the crankshaft pulley.





78. Using the Oil Seal Remover, remove and discard the crankshaft front seal.





79. Remove the 2 bolts and the engine mount bracket.





80. NOTE: Only use hand tools to remove the studs.

Remove the 2 engine mount studs.





81. Remove the 3 bolts and the engine mount bracket.





82. Remove the 22 engine front cover bolts.

Remove and discard the LH VCT assembly bolt and the LH exhaust camshaft sprocket bolt.
- VCT assembly, secondary timing chain and the LH exhaust camshaft sprocket as an assembly.





98. NOTE: When the Camshaft Holding Tool is removed, valve spring pressure will rotate the LH camshafts approximately 3 degrees to a neutral position.

Remove the Camshaft Holding Tool from the LH camshafts.





99. NOTICE: The camshafts must remain in the neutral position during removal or engine damage may occur.

Verify the LH camshafts are in the neutral position.
