Was searching the forums and had no luck, was trying to find the VIN range on the recall for the 2010 L99 Lifters.

Attention: This bulletin only applies to the AFM V8 engines listed above. It DOES NOT apply to Non-AFM Engines. If you are dealing with a Non-AFM engine that is experiencing a similar noise, please refer to Engine Mechanical > Diagnostic Information and Procedures > Symptoms in SI.

This bulletin is being revised to add models. Please discard Corporate Bulletin Number 10-06-01-007B (Section 06 - Engine/Propulsion System).

Condition
Some customers may comment on an engine valve lifter tick noise that occurs after the engine has been shut off for at least two hours. The tick noise may last from two seconds to ten minutes.

Cause
This condition may be caused by any of the following:

• Aerated oil in the valve lifter body, resulting in the valve lifter being unable to purge the air quickly.

• A low engine oil level or incorrect oil viscosity.

• Dirty or contaminated oil.

• A low internal valve lifter oil reservoir level.

• Debris in the valve lifter.
• A high valve lifter leak down rate.

Correction

If the SI diagnostics do not isolate the cause of this valve lifter tick noise and normal oil pressure is noted during the concern, perform the following steps:

Inspect the engine oil condition and level. Refer to Owner Manual > Service and Appearance Care > Checking Things Under the Hood > Description and Operation > Engine Oil in SI.
⇒If the engine oil is more than one quart low, an incorrect oil viscosity is being used or if poor quality/contamination is observed, change the oil and filter.
Note: Allow at least a two hour soak time between engine OFF and start up when evaluating the tick noise.

Start the engine and evaluate the valve lifter tick noise.
⇒If the valve lifter tick noise is still present, replace all 16 valve lifters. Refer to Valve Lifter Replacement in SI.

Parts Information

Note: A V8 AFM engine requires 8 AFM lifters and 8 non-AFM lifters for a total of 16 lifters.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

JCL-2SS · 05-05-2011, 02:14 PM

AFM is Active Fuel Management on L99 Automatic motors only. Chevy dealer replaced my lifters after i had an issue where i was blowing blue smoke on startup out the back.

nitto85 · 05-08-2011, 12:52 PM

I think my lifters are ticking, what are the chances they would replace them on a supercharged motor?

Buffnshine · 05-08-2011, 01:26 PM

none unfortunatly

nitto85 · 05-08-2011, 04:40 PM

Going to call a dealership sometime this week, going to suck if I have to come out of pocket for this, since its a known issue.

Mine doesn't do it every day. Is just a noise issue, or is there the potential for failure?

1FAST SS · 05-08-2011, 04:46 PM

Could this cause excessive smoke from the exhaust? Mine isn't a daily driver, so I don't know if this is normal.

stikSS · 05-08-2011, 05:16 PM

Its an obvious noise that you will hear, especially on startup... It sounds very noisy and like a knock almost.

I can hold off if its just a noise issue, but is it a potential failure issue as well?
