Removing

• ‒ First check whether the valve seat insert rings and if necessary the cylinder head sealing surface can be reworked. If this is not the case then the valve guide should not be replaced.
• ‒ Press the worn valve guides out with drift 3360 from the camshaft side.

Note:

If repair version guides are already fitted in the cylinder head, these must be pressed out from the combustion chamber side. To do this the cylinder head can be supported on the valve spring seats with sleeve VW 421 and press piece VW 447h.

Installing

• ‒ Coat the new valve guides with oil and press with drift 3360 into cold cylinder head from the camshaft side until the shoulder makes contact.

Note:

When the shoulder on guide makes contact, the pressure must not exceed 1.0 t otherwise shoulder may break off.

• ‒ Ream guides out with hand reamer 3363 using plenty of cutting fluid.
• ‒ Rework valve seats .
