ACTION
To diagnose, with the engine running and warm (normal operation temperature), using a mechanic's stethoscope determine if the ticking noise is coming from the left hand intake camshaft at cylinder number 6, (Fig. 1 ). If the ticking noise can be verified, refer to the following Service Procedure.
Fig. 1: Locations To Listen For Ticking Noise
SERVICE PROCEDURE

Rotate the engine clock wise until the cylinder number 6 intake cam lobes are pointing up and the valves are fully closed.
Remove all left hand intake cam caps individually and reinstall them finger tight.
