Valve Clearance
- Adjust valves with engine cold. Remove valve cover. Loosen nut on rocker arm and adjust position of eccentric cam to obtain proper clearance.
- Adjust valves in same sequence as firing order (1-5-3-6-2-4), with valve being adjusted at TDC of compression stroke. Use a feeler gauge to measure clearance between rocker arm eccentric and valve stem.
