ISSUE
Some 2005-2007 Five Hundred, Freestyle, Montego, and 2006-2007 Fusion, Milan, 2006 Zephyr, 2006-2008 Escape and Mariner vehicles built 1/17/2006 thru 5/31/2007, equipped with the 3.0L 4V Duratec engine with exhaust camshaft driven water pumps may exhibit a ticking noise from the left bank cylinder head with the engine at normal operating temperature.
ACTION
Refer to the following Service Procedure to identify and resolve the engine ticking noise.
SERVICE PROCEDURE
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.
For 2008 Escape and Mariner, check the date on the LH cam cover engine label. If the engine build date is 5/16/2007 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 to Workshop Manual (WSM), Section 303-00.
For 2007 Fusion and Milan check the date on the front cover engine 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 to 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 number 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 lb-in (8 N.m) excluding cam cap number 4L camshaft cap.
5. 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.
6. While holding cam cap number 4L in the shifted position, torque the fastener number 9 (inboard) first, to 72 lb-in (8 N.m) then torque fastener number 10. (Figure 3)
7. Install the left hand camshaft cover. Refer to appropriate WSM, Section 303-01.
