Checking the valve guides (VW Beetle)

When repairing an engine with leaky valves, it is not enough to just treat the valves and their seats or replace them. In addition, it is necessary to check the valve guide bushings for wear. This check is especially important for high mileage engines. If the wear is too great, the guide bushings must be replaced (this operation is performed in the workshop).

Using a brush, remove carbon deposits from the valve guides.

Insert a new valve, secure the cylinder head with the combustion chambers facing up. The valve stem should be pressed down, under the guide.



Measure valve runout using a dial indicator by rotating the valve disc.

If the runout exceeds 0.8 mm, replace the valve guide.
