Valve Guide: Testing and Inspection

Valve guide wear, checking

- Place new valve in guide. Valve shaft stem end must be flush with guide.

CAUTION!

- Due to differences in valve stem diameter, make sure that only intake valves are used to check intake guides, and only exhaust valves are used to check exhaust guides.






- Install VW387 on cylinder head, adjacent to guide being checked.
- Rock valve back and forth (arrow) against dial indicator and note total travel.

Wear limit:

- Intake valve guide: 1.0 mm (0.039 in.)

- Exhaust valve guide: 1.3 mm (0.051 in.)
