Valve Guide: Testing and Inspection

Valve Guides, Checking

Special tools, testers and auxiliary items required

• Dial Gauge Holder (VW 387)

• Dial Gauge 0-10 mm (VAS 6079)

Test Sequence

- Insert the valve into guide. Valve stem end must be flush with the guide. Due to the slight difference in stem dimensions, ensure that only an intake valve is used in the intake guide and an exhaust valve in the exhaust guide.








- Determine tip clearance.

Wear Limit






• If wear limit is exceeded, measure again using new valves. If wear limit is still exceeded, replace cylinder head.

• If the valve is to be replaced as part of a repair, use a new valve for the calculation.
