CAUTION:
Install new D-ring seals on the crankcase-to-head tube. It requires several hours after installation for the D-ring seals to relax back to their original size. If the tube assembly is installed before the D-ring seals have relaxed, damage to the D-ring seals can occur.
NOTE:
Late build shown, early build similar.
All vehicles
NOTE:
Check alignment of the oil holes after installing the bearings.
CAUTION:
The patch bolt is unique - do not substitute or engine damage can occur.
NOTE:
Apply Threadlock 262 to the threads prior to installation.
CAUTION:
Do not nick or scratch the camshaft bearings with the camshaft lobes or engine damage can occur.
NOTE:
Apply clean engine oil to the camshaft prior to installing.
NOTE:
Apply clean engine oil to all the bearings.
NOTE:
Do not turn the crankshaft during the main bearing clearance check.
CAUTION:
To prevent engine damage, make sure that the longer main cap bolts (M14 x 2 x 127) are installed inboard and the shorter bolts (M14 x 2 x 114) are installed outboard.
NOTE:
Apply clean engine oil to the lower main bearings.
CAUTION:
To prevent engine damage, make sure that the longer main cap bolts (M14 x 2 x 127) are installed inboard and the shorter bolts (M14 x 2 x 114) are installed outboard.
CAUTION:
To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is removed and reinstalled, it will result in engine vibration and premature transmission component wear.
NOTE:
Lubricate with clean engine oil.
NOTE:
Make sure the ring openings are 120 degrees from each other, or engine damage can occur.
NOTE:
Cam V8 is toward the inside of the engine.
NOTE:
Coat the cylinder walls and piston assembly with clean engine oil before installing.
NOTE:
Install a new press-in-place gasket.
CAUTION:
To prevent engine damage, keep the cam followers in the order in which they were removed. Install all cam followers back in their original positions.
NOTE:
Only the front guides use bolts.
Early build vehicles
Late build vehicles
NOTE:
RH side shown, LH side similar.
All vehicles
NOTE:
Install a new cylinder head gasket with the part number facing up. Verify the top 5 bolt holes and the head gasket push rod holes line up.
NOTE:
Use care to avoid scratching the blue compound on the cylinder head gaskets.
CAUTION:
To prevent engine damage, keep the push rods in the order in which they were removed. Install all push rods back in their original positions.
NOTE:
Higher mileage engines require push rods to be cleaned so the copper colored end of the push rod can be identified.
NOTE:
If a push rod has been replaced, it may not have a copper-colored end and can be installed with either end up.
NOTE:
Coat the end of each valve stem with clean engine oil.
NOTE:
Rotate the crankshaft until the damper locating dowel notch is in the 6 o'clock position.
NOTE:
Apply clean engine oil to the top center of each valve bridge.
CAUTION:
Using too much engine oil on the threads of the cylinder head bolts, can cause damage to the threads and poor sealing. Using anti-seize compounds, grease or any other lubricants other than engine oil on the cylinder head bolt threads can affect the true torque value of the bolts.
NOTE:
Lightly lubricate the new cylinder head bolt threads and flanges with clean engine oil.
NOTE:
Left cylinder head shown, right cylinder head similar.
Early build vehicles
CAUTION:
To prevent engine damage, check that the crankcase-to-head tube assemblies bottom out in the branch tube assembly. The oil rail, crankcase-to-head tube and the fuel injectors will not function correctly if these tubes are not bottomed out.
All vehicles
CAUTION:
If the fuel injector oil inlet O-ring is damaged, a new fuel injector must be installed.
NOTE:
Lubricate the fuel injector and O-rings liberally with clean engine oil.
CAUTION:
Failure to tighten the injector properly can lead to engine failure.
CAUTION:
To prevent engine damage, do not use air tools to install the fuel injectors. The snap ring that extracts the injector can dislodge and fall into the oil drain hole.
CAUTION:
Make sure the injector wiring is clear of all moving parts or engine damage can occur.
NOTE:
Apply clean engine oil to the top fuel injector O-rings before installing the high-pressure oil rail.
Late build vehicles
NOTE:
Apply clean engine oil to the crankcase-to-head tube prior to installing.
All vehicles
NOTE:
The crankshaft rear oil seal and wear sleeve are installed as an assembly.
NOTE:
Lubricate the outer diameter of the rubber seal with a solution of dish soap and water (approximately 50/50 mix) prior to assembly. Do not use any other type of lubricant.
NOTE:
Apply a bead of Threadlock 262 around the circumference of the outer rear edge of the secondary crankshaft flange.
NOTE:
The rear main seal and wear sleeve are correctly seated when the crankshaft begins to rotate.
NOTE:
Use guide studs to aid in installation. Studs must be fabricated locally.
NOTE:
Install oil pump drive rotors with marks pointing outward.
NOTE:
Install a new O-ring seal.
NOTE:
Apply Threadlock 262 to the outer circumference of the leading edge of the crankshaft.
NOTE:
The seal and wear sleeve must not be separated.
CAUTION:
To prevent engine damage, you must always install 4 new bolts when installing the vibration damper.
NOTE:
Do not use anti-seize compounds, grease, or any lubricants. Lubricants have an adverse effect on the torque results.
NOTE:
Install a new O-ring on the coolant pump.
CAUTION:
To prevent engine damage, do not use air powered tools when installing the valve cover.
NOTE:
RH side shown, LH side similar.
NOTE:
Clean and inspect the O-ring.
NOTE:
Clean and apply clean engine oil to the O-rings.
Early build vehicles
Late build vehicles
CAUTION:
To prevent engine damage, use only approved pump cover seal. Substitution can cause damage to the pump cover.
CAUTION:
To prevent engine damage, the high-pressure oil pump cover must be firmly seated on the O-ring seal to prevent cracking the cover plate.
NOTE:
Apply clean engine oil to the high-pressure oil pump O-ring seal prior to installing the high-pressure pump cover.
All vehicles
CAUTION:
In the event of a catastrophic engine failure, always install a new oil cooler cover assembly (with oil cooler). Foreign material cannot be removed from the oil cooler.
NOTE:
The old oil cooler cover bolts or new self-tapping bolts must be used to cut the threads in the new oil cooler cover.
NOTE:
Install new sealing washers.
NOTE:
Install a new O-ring on the thermostat.
Early build vehicles
All vehicles
NOTE:
Install a new O-ring on the oil indicator and tube. Apply clean engine oil to the O-ring.
NOTE:
LH shown, RH similar.
NOTE:
Lightly lubricate the O-ring seal with clean engine oil prior to installing.
NOTE:
LH side shown, RH side similar.
