Condition

Some customers may comment or technicians may notice needle bearings being found during an engine oil change. The bearings may be found in either the drain pan used or on the magnetic oil pan drain plug.

Cause

One or more rocker arms may have experienced a bearing failure.

Correction

Inspect all of the rocker arms for bearing retainer cap failure. If one or more defective rocker arms are found, replace all 16 rocker arms. Refer to the Engine Mechanical sub-section in the appropriate Service Manual.

If no condition with the rocker arms is found, refer to the service history for previous rocker arm repair. If previous rocker arm repair was made, then the engine may not have been thoroughly cleaned of loose roller bearings. If no previous rocker arm repair was made, then look for another condition.

Remove the oil pan and clean out any additional bearings found within the oil pan. Refer to the Engine Mechanical sub-section in the appropriate Service Manual.

Install the oil pan. Refer to the Engine Mechanical sub-section in the appropriate Service Manual
