ISSUE:
A metallic "ticking" noise from the engine valve hydraulic lash adjusters may occur after a hot soak. This noise may be heard under the following
conditions:
^
When returning to idle speed after freeway driving
^
After a hot soak at idle speed just after restarting
This condition may be caused by the factory oil becoming contaminated and is usually noticed in the first 1000-3000 miles (1600-4800 km) of new
vehicle operation. The contamination can cause the oil to have increased foaming characteristics.
ACTION:
Flush the engine lubrication system and replace the engine oil. Refer to the following procedure for service details
NOTE:
THE FOLLOWING TWO SYMPTOMS ARE NORMAL AND REQUIRE NO CORRECTIVE ACTION: (1) "TICKING" NOISE FOR UP TO 3
SECONDS AFTER INITIAL START UP. (2) NOISE JUST AFTER OIL AND FILTER CHANGE. AIR IS PURGED OUT THROUGH NORMAL
DRIVING.
