Note

♦

If the valve has to be renewed as part of a repair, use a new

valve for the measurement.

VW 387- to cylinder head.

– Insert valve into guide.
• End of valve stem must be flush with guide.
– Measure the amount of sideways play.

ther damage, the following steps are required after completion

of repair work: clean the oil galleries carefully and renew the

oil spray jets, engine oil cooler and oil filter.
