Valve Guide, Checking

Special tools, testers and auxiliary items required

• Dial Gauge Holder (VW 387)

• Dial Gauge

- Insert a new valve into the guide. The tip of the valve stem must be flush with the guide. Due to the slight differences in stem dimensions, ensure that only an intake valve is used in the intake guide and an exhaust valve in the exhaust guide.






- Determine the tilt clearance:

Wear limit: maximum 1.3 mm

- If the tilt clearance exceeds the wear limit, the cylinder head must be replaced.
