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.
