After all 12 capscrews on one head have been torqued to

298 N•m [220 ft-lb], they must be rotated in the tightening

direction an additional 90 degrees. Rotate the capscrew

until the mark on the cylinder head is between the next

two marks joined by an arc (more than one flat and less

than two flats).

NOTE: When using torque plus angle, the tolerance on the

90 degree angle of rotation is one to two flats (90° plus or

minus 30° ). If the capscrew is rotated beyond two flats, do

not loosen the capscrew. The clamp load is still acceptable;

however, rotating the capscrew beyond two flats causes

additional stretch and reduces the number of reuses. With

proper torquing, the capscrew can typically be reused for the

life of the engine.

Camshaft - Installation

Apply a film of LubriplateT 105 or its equivalent to both

sides of the camshaft thrust washer.

Caution: The oil grooves on the thrust washer must be

toward the camshaft gear to prevent thrust washer fail-

ure.

Install the thrust washer on the camshaft.

Install four camshaft pilots, Part No. 3375268, over the

base circle of the valve lobes between the camshaft jour-

nals.

Use a rubber band to hold the installation pilots in place.

The rubber band must straddle the valve lobes.

Apply a film of LubriplateT 105 or its equivalent to the

camshaft journals and the camshaft bushings.

Rotate the camshaft slowly as it is being installed in the

cylinder block.
