Valve Guides, Checking: Procedure

WARNING: This page is about a different car, the 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If valve is replaced during repair, use new valve for measurement.

Due to different stem diameters, only use an intake valve in the intake guide and an exhaust valve in the exhaust guide.

-- Secure the Dial Gauge VAS 6079 to the cylinder head with the Universal Dial Gauge Mount VW 387.
