7. If the camshaft-to-holder oil clearance is out of tol-

erance:

— And the camshaft has already been replaced, you

must replace the cylinder head.

— If the camshaft has not been replaced, first check

the total runout with the camshaft supported on

V-blocks.

Camshaft Total Runout:

Standard (New): 0.03 mm (0.001 in) max.

Service Limit: 0.04 mm (0.002 in)

Rotate camshaft

while measuring.

If the total runout of the camshaft is within toler-

ance, replace the cylinder head.

If the total runout is out of tolerance, replace the

camshaft and recheck. If the oil clearance is still

out of tolerance, replace the cylinder head.
8. Check the cam lobe height wear.

Cam Lobe Height Standard (New):

INTAKE: 39.203 mm (1.5434 in)

EXHAUST: 38.875 mm (1.5305 in)

Check this area for wear.ProCarManuals.com

Camshaft/Rocker Arms and

Camshaft Seal

Installation

CAUTION:

• Make sure that all rockers are in alignment with their

valves when torquing the rocker assembly bolts.

• Valve locknuts should be loosened and adjusting

screws backed off before installation.

• To prevent the rocker arm assembly from coming

apart, leave the camshaft holder bolts in the holes.

1. After wiping down the camshaft and journals in the

cylinder head, lubricate both surfaces and install the

camshaft.

2. Install the camshaft seal with the open side (spring)

facing in.

Lubricate the cam lobes after reassembly.

KEYWAY

3.
CAMSHAFT OIL SEAL CAMSHAFT

Seal housing surface should be dry. Keyway up.

Apply a light coat of oil to camshaft

and inner lip of seal.

Apply liquid gasket to the head mating surfaces of

the No. 1 and the No. 7 camshaft holders.

— Apply liquid gasket to the shaded areas.

NOTE: Be sure to wipe any liquid gasket off the sur-

face of the No. 7 camshaft holder where the distrib-

utor is to be attached.
