To diagnose, with the engine running and warm (normal operation temperature), using a mechanic's stethoscope determine if ticking noise is coming from the left hand exhaust camshaft at cylinder number 6 (Figure 1). If ticking noise can be verified, refer to the following Service Procedure.

Remove the left hand camshaft cover. Refer to Workshop Manual (WSM), Section 303-01 of the appropriate manual.

Remove all left hand exhaust cam caps individually and reinstall them finger tight.
Torque bolts in sequence shown in Figure 2, to 72 lb-in (8 N-m) excluding cam cap number 4L camshaft cap.


Figure 2 - Article 06-8-11


Using a screw driver positioned on each side of the top of cam cap number 4L (Figure 3) apply hand pressure and shift cam cap number 4L toward the exhaust side of the cylinder head.


Figure 3 - Article 06-8-11


While holding cam cap number 4L in the shifted position, torque the fasteners number 9 (inboard) first, to 72 lb-in (8 N-m) then torque fastener number 10 (Figure 3).
