NOTE:
Note the position of the alignment dowel on the engine front cover.
NOTE:
Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surface. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove all traces of sealant.
NOTE:
Note the location of all bolts and stud bolts for installation.
NOTE:
Only use hand tools when removing or installing the spark plugs or damage can occur to the cylinder head or spark plug.
NOTE:
LH shown, RH similar.
NOTE:
This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30RFF" (orange in color).
NOTE:
Do not scratch the camshaft sealing surface while removing the camshaft oil seal. If scratched, camshaft oil seal leakage may occur.
NOTE:
The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.
NOTE:
Do not allow the camshaft to rotate from the neutral position while removing the camshaft phaser and sprocket or damage to the engine may occur.

Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for removal of the camshaft phaser and sprocket bolts.
NOTE:
Cylinder head camshaft bearing caps must be assembled in their original positions. Some engines have factory markings on the camshaft bearing caps (as shown in illustration). Engines that do not have the factory markings must be marked for correct position and orientation prior to removal. Failure to install the camshaft bearing caps in their original positions may result in severe engine damage.
NOTE:
After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (1L and 5L) first, or damage to the thrust caps may occur.
NOTE:
Make sure the camshaft bearing caps are marked as instructed in the previous step.
NOTE:
The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.

Clearly mark the position and orientation of the pistons, connecting rods, connecting rod caps and connecting rod bearings for reassembly.
NOTE:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod.
NOTE:
If the main bearings are being reused, mark them for correct position and orientation for reassembly.
