- Carefully lift off the cover, exposing the engine components underneath.
- Locate the valve assembly; it’s typically near the top of the engine, close to the cylinder head.
Measuring Valve Clearance
- Utilize a feeler gauge to measure the gap between the rocker arm and valve stem.
- Insert the gauge into the gap.
- Note the size of the clearance; it should match specifications listed in your owner’s manual.
- If the gap is too tight or too loose, proceed to adjust the valve clearances.
- Loosen the locknut on the rocker arm with a wrench.
