This chart is for selecting main bearings 2, 3 and 4 only.
NOTE:
Lubricate the crankshaft bearing journals with clean engine oil.
NOTE:
The oil groove on the thrust washer must face toward the rear of the engine (against the crankshaft thrust surface).
NOTE:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod or engine damage may occur.
NOTE:
Do not allow the piston connecting rods to come in contact with the piston cooling jets or engine damage may occur.
NOTE:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod or engine damage may occur.
NOTE:
The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
NOTE:
The connecting rod caps are of the "cracked" design and must mate with the connecting rod ends. Excessive bearing clearance will result if not mated correctly.
NOTE:
Main bearing caps are removed for clarity.
NOTE:
Oil pump must be held against the cylinder block until all bolts are tightened.
NOTE:
The 2 oil pump screen and pickup tube-to-oil pump bolts must be tightened prior to tightening the oil pump screen and pickup tube-to-spacer bolt.
NOTE:
If the rear crankshaft seal retaining plate 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 5 minutes, whichever is longer. Failure to follow this procedure may cause future oil leaks.
Fig 20: Locating Bead Of Silicone Gasket And Sealant On Rear Crankshaft Seal Retainer Mating Surface Of Engine Block
NOTE:
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 oil pan is not installed and the fasteners tightened within 5 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage. If this timing cannot be met, tighten fasteners 7, 8, 9 and 10 to 8 Nm (71 lb-in) within 5 minutes of applying the sealer and final torque all of the fasteners within 1 hour of applying the sealer.

NOTE:
Make sure all coolant residue and foreign material are cleaned from the block surface and cylinder bore. Failure to follow these instructions may result in engine damage.
NOTE:
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.
NOTE:
The cylinder head bolts must be discarded and new bolts installed. They are a tighten-to-yield design and cannot be reused.
NOTE:
Do not turn the crankshaft until instructed to do so.
NOTE:
LH shown in illustration, RH similar.
NOTE:
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 scraper to clean the sealing surfaces.
NOTE:
Lubricate the O-ring seal with clean engine coolant prior to installing.
NOTE:
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 scraper to clean the sealing surfaces.

It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain guide. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain guide.
NOTE:
It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain tensioner arm. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain tensioner arm.
NOTE:
Complete the following 3 steps on both the LH and RH primary timing chain tensioners.
NOTE:
Do not compress the ratchet assembly or damage to the tensioner will occur.
NOTE:
Lubricate the camshaft roller follower and hydraulic lash adjuster assemblies with clean engine oil prior to installation.
NOTE:
Lubricate the camshafts with clean engine oil prior to installation.
NOTE:
Intake camshaft shown in illustration, exhaust camshaft similar.
NOTE:
It may be necessary to rotate the exhaust camshaft slightly (using a wrench on the flats of the camshaft) to seat the VCT assemblies onto the camshafts.
NOTE:
Use a wrench on the flats of the camshaft to hold the camshafts while tightening the VCT assembly bolts.
NOTE:
It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain guide.
NOTE:
It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain tensioner arm.
NOTE:
The Variable Camshaft Timing (VCT) variable force solenoid pins must be fully depressed to avoid interference with the VCT valve tips when installing the engine front cover. Failure to follow these instructions can result in damage to the engine.
NOTE:
LH shown in illustration, RH similar.
NOTE:
The engine front cover must be installed and all fasteners final tightened within 5 minutes of applying the sealer. If this cannot be accomplished, install the engine front cover and tighten fasteners 6, 7, 8, 9, 10 and 11 to 8 Nm (71 lb-in) within 5 minutes of applying the sealer. All of the fasteners must then be final tightened within 1 hour of applying the sealer. If this time limit is exceeded, all 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:
The engine front cover must be installed and all fasteners final tightened within 5 minutes of applying the sealer. If this cannot be accomplished, install the engine front cover and tighten fasteners 6, 7, 8, 9, 10 and 11 to 8 Nm (71 lb-in) within 5 minutes of applying the sealer.

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

NOTE:
If not secured within 5 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
NOTE:
Lubricate the new coolant pump O-ring seal with clean engine coolant.
NOTE:
Lubricate the new thermostat housing O-ring seal with clean engine coolant.
NOTE:
Installation of new seals is only required if damaged seals were removed.
NOTE:
Installation of new seals is only required if damaged seals were removed.

NOTE:
If the valve cover is not installed and the fasteners tightened within 5 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.

NOTE:
Apply a small amount of dielectric grease to the inside of the ignition coil-on-plug boots before attaching to the spark plugs. RH shown in illustration, LH similar.
NOTE:

NOTE:
Lubricate the seal lips and bore with clean engine oil prior to installation.
NOTE:
The flexplate bolts are torque-to-yield design and are not reusable.
