Valves, Adjust
A longer or shorter pushrod is available to compensate for dimensional changes in the valve train. If clearance is less than specified, a shorter pushrod should be used. If clearance is more than the maximum, a longer pushrod should be used.
Using an auxiliary starter switch crank engine until No. 1 cylinder is at TDC of compression stroke, Fig. 3, then compress valve lifter using tool No. T82C-6500-A or equivalent, Fig. 4. At this point, the following valves can be checked:
No. 1 Intake No. 1 Exhaust
No. 3 Intake No. 2 Exhaust
No. 6 Intake No. 4 Exhaust
Ensure valve clearances are .088 - .189 inch on V6-232 engines and .085 - .185 inch on V6-182 engines. After clearance on these valves has been checked, rotate crankshaft until No. 5 cylinder is at TDC compression stroke (1 revolution of crankshaft), Fig. 3, and then compress valve lifter using tool described previously and check the following valves:
No. 2 Intake No. 3 Exhaust
No. 4 Intake No. 5 Exhaust
No. 5 Intake No. 6 Exhaust
Adjust valve clearances to .088 - .189 inch on V6-232 engines and .085 - .185 inch on V6-182 engines.
