CAUTION:
Make sure the components are installed in the correct location.
NOTE:
Lubricate the crankshaft main bearings prior to installation.
CAUTION:
The crankshaft journals must be protected from damage when installing the crankshaft.
CAUTION:
The main bearings are precision selective fit. Inspect the bearing clearance. Refer to ENGINE SYSTEM-GENERAL INFORMATION
.
NOTE:
If the rear main bearing cap is not installed within four minutes, remove the sealant and reapply.
NOTE:
Lubricate the crankshaft rear seal lips with clean engine oil prior to installation.
CAUTION:
Inspect the piston clearance. Refer to ENGINE SYSTEM-GENERAL INFORMATION
.
CAUTION:
Do not damage the cylinder wall with the sharp edges of the connecting rod.
CAUTION:
Inspect the connecting rod bearing clearance. Refer to ENGINE SYSTEM-GENERAL INFORMATION
.
CAUTION:
The connecting rod cap will fit only one way.
CAUTION:
All timing marks must be aligned with the No. 1 cylinder set on top dead center (TDC) of the compression stroke or the synchronizer assembly will not be installed correctly.
NOTE:
The crankshaft must not be turned until the camshaft synchronizer is installed.
CAUTION:
Always use new bolts.
NOTE:
Lubricate the bolts with clean engine oil prior to installation. Make sure the bolts are installed in the correct location.

Lubricate the parts with clean engine oil before assembly.
CAUTION:
After installation, do not loosen the synchronizer bolt and rotate the synchronizer assembly. The synchronizer assembly is not adjustable. Do not loosen the synchronizer bolt after the alignment tool has been removed in order to align the CMP electrical connector for any reason. If the electrical connector is not in the correct position, the synchronizer assembly must be removed, the alignment tool and the assembly reinstalled if the engine has not been rotated from top dead center (TDC) of the compression stroke on the No. 1 cylinder.
CAUTION:
A Synchronizer Alignment Gauge must be used during the installation of the synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
NOTE:
Always coat the synchronizer drive gear with clean engine oil prior to installation.
NOTE:
During installation, the arrow on the Synchronizer Alignment Gauge will rotate clockwise as the gears engage.

If the oil pan is not installed within four minutes, remove the sealer and reapply.
NOTE:
Inspect the valve cover gaskets for damage. Install a new gasket, if necessary.
NOTE:
Install a new oil level indicator tube O-ring seal.
NOTE:
The lower intake manifold must be installed within four minutes of applying the sealant.
NOTE:
Make sure the bolts are installed in the correct locations.
