Electronic Fuel Injection Update
Bulletin 01-06-01-029 was released in December 2001 regarding excessive engine oil consumption in 1999-2002 Chevrolet and GMC C/K Trucks and 2002 Cadillac Escalades with a 5.3L (LM7), or 6.0L (LQ9/LQ4) engine.
If engine oil consumption is verified by following the bulletin procedure, a fixed-orifice PCV valve is to be installed.
An article titled Changes to the Gen III Engine Family Fuel Injection System in the January 2002 issue of TechLink incorrectly stated that the throttle body and PCV valve must be matched.
You may use the fixed- orifice PCV valve as stipulated in the bulletin without affecting vehicle operation.
