Cylinder Head Cover Bolts 10 Nm (90 in. lbs)

HEAD BOLT REUSE/REPLACE

The cylinder head bolts must be examined BEFORE reuse. If the threads are necked down (2) the bolts should be replaced.

INTAKE MANIFOLD





Intake Manifold - Lower 28 Nm (250 in.lbs)

Intake Manifold - Upper 12 Nm (105 in.lbs)
- Starting in the center working outward in a cross sequence pattern.

MAIN BEARING CAP Torque

NOTE: The main bearing cap bolts must be tightened in the proper sequence. First the inner main cap bolts, secondly the windage tray bolts, lastly the main cap tie (horizontal) bolts.

NOTE: Lubricate main bearing cap inner bolts (2) with engine oil before installation.

Install each main cap (1) and tighten inner bolts (2) finger tight. Align the location reference mark scribed on the #2 main bearing cap during disassembly.






CAUTION: The #2 main bearing cap must be centered over the inner bolt holes located on the block. Failure to center the bearing cap can result in contact with the crankshaft counterweights and thrust bearing failure.

Following verification of proper #2 bearing cap centering, finish tightening the main bearing cap inner bolts an additional 90° turn.










Install windage tray (3). Lubricate bolts with engine oil. Finger tighten all bolts first, then tighten to 28 Nm + 90° turn (20 ft. lbs. + 90° turn) beginning with the inside bolts tightening outward.
Install oil pickup tube (1) and tighten bolt to 28 Nm (20 ft. lbs.).






Install the main cap tie (horizontal) bolts and tighten to 28 Nm (20 ft. lbs.).
