A probable cause for this condition is the intake rocker shaft clearance is excessive at the number two cylinder. To correct this condition, adjust the valve clearances or replace the cam holder and the adjoining intake rocker arm shafts at the number two cylinder.

Repair Procedure:
1) Measure the intake valve clearance at the number two cylinder intake valve closest to cylinder number one (Figure 1). If the clearance is more than .040 mm, replace the cam holder. If the clearance is less than .040 mm, go to next step.

2) Adjust the valve clearance (Figure 2). If no adjustment screw threads are visible above the locknut, replace the cam holder.
