Camshaft

Removal (Steps 81-119)
81. Disconnect the heated PCV valve electrical connector.





82. Detach all of the wiring harness retainers from the RH valve cover and stud bolts.
83. Disconnect the LH VCT solenoid electrical connector.





84. Disconnect the 3 LH coil-on-plug electrical connectors.





85. Detach all of the wiring harness retainers from the LH valve cover and stud bolts.

86. NOTE: LH shown, RH similar.

Remove the 6 bolts and the 6 coil-on-plugs.





87. Remove the 11 stud bolts and the LH valve cover.
^ Discard the gasket.





88. Remove the bolt, the 10 stud bolts and the RH valve cover.
^ Discard the gasket.





89. NOTE: VCT solenoid seal removal shown, spark plug tube seal removal similar.

Inspect the VCT solenoid seals and the spark plug tube seals. Install new seals if damaged.
^ Using the special tools, remove the seal(s).





90. Remove the 3 bolts and the power steering pump.





91. Remove the 3 bolts and the accessory drive belt tensioner.





92. Using the special tool, remove the crankshaft bolt and washer.
^ Discard the bolt.





93. Using the special tool, remove the crankshaft pulley.





94. Using the special tool, remove and discard the crankshaft front seal.





95. Remove the 2 engine mount studs.





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





97. Remove the 22 engine front cover bolts.





98. Install 4 of the engine front cover bolts (finger tight) into the 4 threaded holes in the engine front cover.
1 Tighten the bolts one turn at a time in a criss-cross pattern until the engine front cover-to-cylinder block seal is released.
2 Remove the engine front cover.





99. CAUTION: Place clean, lint free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine.

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 that make leak paths. Use a plastic scraping tool to remove all traces of sealant.

CAUTION: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.

Clean all engine sealing surfaces, including the engine front cover and cylinder block.
1 Remove any large deposits of silicone or gasket material with a plastic scraper.
2 Apply silicone gasket remover, following package directions, and allow to set for several minutes.
3 Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4 Apply metal surface prep, following package directions, 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.
100. Rotate the crankshaft clockwise and align the timing marks on the variable camshaft timing (VCT) assemblies as shown.





101. NOTE: The special tool will hold the camshafts in the top dead center position.

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





102. NOTE: The special tool will hold the camshafts in the top dead center position.

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





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





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





105. Remove and discard the VCT housing seals.





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





107. Remove the primary timing chain tensioner arm.





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





109. Remove the primary timing chain.





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





111. 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.





112. 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.





113. CAUTION: The camshafts must remain in the neutral position during removal.

Verify the LH camshafts are in the neutral position.





114. CAUTION: 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
115. Compress the RH 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 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.





117. Remove the special tool from the RH camshafts.





118. CAUTION: The camshafts must remain in the neutral position during removal.

Rotate the RH camshafts counterclockwise to the neutral position.





119. CAUTION: 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.
