41. NOTICE: Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.

NOTICE: Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.

NOTE: The No. 1 cylinder is at Top Dead Center (TDC) when the stud on the engine block fits into the slot in the handle of the Crankshaft Holding Tool.

Position the crankshaft so the No. 1 cylinder is at TDC with the Crankshaft Holding Tool.





42. Remove the Crankshaft Holding Tool.





43. Position the LH (inner) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.





44. Install the LH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.





45. NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.

Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner and the 2 bolts.

- Tighten to 25 Nm (18 lb-ft).





46. Remove the retaining clip from the LH timing chain tensioner.




47. Position the RH (outer) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.





48. Install the RH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.





49. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and the 2 bolts.
- Tighten to 25 Nm (18 lb-ft).





50. Remove the retaining clip from the RH timing chain tensioner.





51. Make sure that the copper (marked) chain links are lined up with the dots on the crankshaft sprockets and the camshaft sprocket.





52. Install the crankshaft sensor ring on the crankshaft.





53. NOTE: Camshaft roller follower is removed from art for clarity.

Install the Valve Spring Compressor Spacer between the valve spring coils to prevent valve stem seal damage.





54. NOTICE: The camshaft roller followers must be installed in their original locations. Failure to follow these instructions may result in engine damage.

NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed.

NOTE: It may be necessary to push the valve down while compressing the spring.

NOTE: Position the cam lobe away from the valve stem prior to installing each camshaft roller follower.

Use the Valve Spring Compressor to compress the valve springs and install the camshaft roller follower.





55. Repeat the previous 3 steps for each camshaft roller follower.

56. NOTICE: Only use hand tools when removing or installing the spark plugs or damage can occur to the cylinder head or spark plug.

NOTE: Use compressed air to remove any foreign material from the spark plug well before removing the spark plugs.

NOTE: If an original spark plug is used, make sure it is installed in the same cylinder from which it was taken. New spark plugs can be used in any cylinder.

NOTE: Refer to the specifications for correct spark plug identification.

Install the 8 spark plugs.

- Tighten to 18 Nm (159 lb-in).

57. NOTICE: 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 with silicone gasket remover and metal surface prep. Follow the directions on the packaging. 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: Make sure that the engine front cover gasket is in place on the engine front cover before installation.

Apply a bead of silicone gasket and sealant along the cylinder head-to-cylinder block surface at the locations shown.





58. Install a new engine front cover gasket on the engine front cover. Position the engine front cover onto the dowels. Install the fasteners finger-tight.





59. Tighten the 15 front cover fasteners in the sequence shown to 25 Nm (18 lb-ft).









60. Lubricate the engine front cover and the crankshaft front seal inner lip with clean engine oil.





61. Using the Crankshaft Front Oil Seal Installer, the Front Cover Oil Seal Installer and the Crankshaft Vibration Damper Installer, install the crankshaft front seal into the engine front cover.





62. 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. Follow the directions on the packaging. 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.

Apply silicone gasket and sealant to the Woodruff key slot on the crankshaft pulley.





63. Using the Crankshaft Vibration Damper Installer, install the crankshaft pulley.





64. NOTE: Use a suitable Strap Wrench (such as 303-D055) to hold the pulley while tightening the bolt.

Tighten the new crankshaft pulley bolt in 4 stages.

- Stage 1: Tighten to 120 Nm (89 lb-ft).

- Stage 2: Loosen one full turn.

- Stage 3: Tighten to 50 Nm (37 lb-ft).

- Stage 4: Tighten an additional 90 degrees.





65. NOTICE: 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.

Inspect and clean the valve cover sealing surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
66. Apply instant adhesive completely around the gasket groove in the LH valve cover. Install the new valve cover gasket.





67. NOTE: If not secured within 4 minutes, the sealant must be removed and cleaned with silicone gasket remover and metal surface prep. Follow the directions on the packaging. 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.

Apply silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.





68. Position the LH valve cover and gasket on the cylinder head and install the fasteners loosely.





69. Position the LH valve cover and tighten the 11 fasteners in the sequence shown to 10 Nm (89 lb-in).









70. Apply instant adhesive completely around the gasket groove in the RH valve cover. Install the new valve cover gasket.





71. 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. Follow the directions on the packaging. 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.

Apply silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.




72. Position the RH valve cover and gasket on the cylinder head and install the fasteners loosely.





73. Position the RH valve cover and tighten the 11 fasteners in the sequence shown to 10 Nm (89 lb-in).
