Condition
Some customers may comment on a tick type noise coming from the engine while the engine is running during cold or hot operation. The condition will
be most noticeable on vehicles that have been stored for extended periods of time without running the engine or on vehicles following a repair to the
valve lifters and camshafts.
Cause
This condition may be caused by oil drain down. Air may get trapped in the valve lifters, not allowing for proper lifter adjustment. This condition may
also be referred to as "lifter bleed down".
Correction
Replace the valve lifters with P/N 91177364. Refer to the Lifter Replacement procedure in the Engine Mechanical sub-section of the service manual.
Part Information
Parts are expected to be available from GMSPO on June 27, 2003.
