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

For 2008 Escape and Mariner, check the date on the left-hand cam cover engine label. If the engine build date is 5/16/20007 or before, refer to the following to identify and resolve the engine ticking noise. For engines built after this date, this procedure does not apply; refer the Workshop Manual (WSM), Section 303-00.

1. Remove the left-hand camshaft cover. Refer to WSM, Section 303-01 of the appropriate manual.

2. Rotate the engine clockwise until the cylinder #6 exhaust cam lobes are pointing up and the valves are fully closed.

3. Remove all left-hand exhaust cam caps individually and reinstall them finger tight.

4. Torque bolts in sequence as shown in Figure 2, to 72 lbs.-in. (8 Nm) excluding cam cap #4L camshaft cap.

5. Using a screwdriver positioned on each side of the top of cam cap #4L (see Figure 3), apply hand pressure and shift cam cap #4L toward the exhaust side of the cylinder head.
