Note! Measurements should only be taken on a cold engine. A suitable temperature is approximately 20° C.
Use feeler gauge 999 5752 Feeler gauge See: Tools and Equipment/999 5752 Feeler Gauge.
Press with a finger so that the feeler gauge lies parallel to the upper side of the tappet (see illustration).
