APPLIED VEHICLES:
All vehicles with VG30E or VG33E engine.

APPLIED DATES:
Vehicles built before October 13, 2003

IF YOU CONFIRM:

The valve lifters make a rattle/clatter noise for 2-3 seconds when the engine is started cold,

NOTE:
^ To duplicate this incident, the engine usually requires an overnight "cold-soak".

^ You should hear the noise coming from one or both valve covers.

^ A moderate amount of engine noise that may occur during starting or during the time needed for oil pressure to build (about 1 second) is considered normal, and does not require repair.

ACTION:

Replace the valve lifters with the ones listed in the Parts Information.

^ Go to the EM section of the appropriate Service Manual (ESM) for lifter replacement instructions.
