102. Install 6 of the engine front cover bolts (finger tight) into the 6 threaded holes in the engine front cover.
^ Tighten the bolts one turn at a time in a criss-cross pattern until the engine front cover-to-cylinder block seal is released.
- Remove the engine front cover.





103. CAUTION: Only use a 3M Roloc Bristle Disk (2-in white, part number 07528) to clean the engine front cover. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean the engine front cover. These tools cause scratches and gouges that make leak paths.

Clean the engine front cover using a 3M Roloc Bristle Disk (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15,000 rpm.
^ Thoroughly wash the engine front cover to remove any foreign material, including any abrasive particles created during the cleaning process.

104. CAUTION: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.

CAUTION: Do not use wire brushes, power abrasive discs or 3M Roloc Bristle Disk (2-in white, part number 07528) to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. They also cause contamination that will cause premature engine failure. Remove all traces of sealant, including any sealant from the inner surface of the cylinder block and cylinder head.

Clean the sealing surfaces of the cylinder heads, the cylinder block and the oil pan in the following sequence.
1. Remove any large deposits of silicone or gasket material.
2. Apply silicone gasket remover and allow to set for several minutes.
3. Remove the silicone gasket remover. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4. Apply metal surface prep, to remove any remaining traces of oil or coolant and to prepare the surfaces to bond. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
5. Make sure the 2 locating dowel pins are seated correctly in the cylinder block.

105. Rotate the crankshaft clockwise and align the timing marks on the VCT assemblies as shown.





106. NOTE: The special tool will hold the camshafts in the top dead center (TDC) position.

Install the special tool onto the flats of the LH camshafts.





107. NOTE: The special tool will hold the camshafts in the TDC position.

Install the special tool onto the flats of the RH camshafts.





108. Remove the 3 bolts and the RH VCT housing.





109. Remove the 3 bolts and the LH VCT housing.





110. Remove and discard the VCT housing seals.





111. Remove the 2 bolts and the primary timing chain tensioner.





112. Remove the primary timing chain tensioner arm.





113. Remove the 2 bolts and the lower LH primary timing chain guide.





114. Remove the primary timing chain.





LH camshafts
115. Compress the LH secondary timing chain tensioner and install a suitable lockpin to retain the tensioner in the collapsed position.





116. NOTE: The VCT bolt and the exhaust camshaft bolt must be discarded and new ones installed. However, the exhaust camshaft washer is reusable.

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





117. NOTE: When the special tool is removed, valve spring pressure will rotate the LH camshafts approximately 3 degrees to a neutral position.

Remove the special tool from the LH camshafts.





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

Verify the LH camshafts are in the neutral position.





119. NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.

Remove the bolts and the LH camshaft bearing caps.
^ Remove the LH camshafts.





RH camshafts
120. Compress the RH secondary timing chain tensioner and install a suitable lockpin to retain the tensioner in the collapsed position.





121. NOTE: The VCT bolt and the exhaust camshaft bolt must be discarded and new ones installed. However, the exhaust camshaft washer is reusable.

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





122. Remove the special tool from the RH camshafts.





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

Rotate the RH camshafts counterclockwise to the neutral position.





124. NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.

Remove the bolts and the RH camshaft bearing caps.
^ Remove the RH camshafts.
