If a customer brings in his vehicle with a ticking noise in the left bank cylinder head engine area, refer to the following service procedure to identify and resolve the issue.

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.

For 2007 Fusion and Milan, check the date on the front cover label. If the engine build date is 5/9/2007 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 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.

6. While holding cam cap #4L in the shifted position, torque fastener #9 (inboard) first, to 72 lbs.-in. (8 Nm), then torque fastener #10 (Figure 3).

7. Install the left-hand camshaft cover. Refer to the appropriate WSM, Section 303-01.
