DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in DealerCONNECT/
Service Library, verify all related systems are functioning as designed. If DTCs or symptom conditions, other
than the ones listed above are present, record the issues on the repair order and repair as necessary
before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above, perform the Diagnosis Procedure.
1. Raise and lower RPM to confirm the noise is coming from the engine. Listen and determine if the noise
is coming from the valvetrain of the engine. Use of a stethoscope may be necessary.
2. Is the noise coming from the engine valvetrain?
• YES>>> Proceed to Step 3 of the Diagnosis Procedure.
• NO>>> This Bulletin does not apply. Normal diagnosis should be performed.
3. Remove the valve cover of the suspected cylinder head. Refer to the detailed service procedures
available in DealerCONNECT/Service Library under: 09 - Engine, 3.6L / Cylinder Head / Cover(s),
Cylinder Head / Removal and Installation.
4. Inspect the intake lash adjuster(s) for a collapsed condition. Press down on the intake rocker arm in a
manner that would compress the intake lash adjuster(s). Normal intake adjuster(s) should feel very firm
and difficult to compress. If the intake lash adjuster(s) can be compressed or there is lash between
the rocker arm and cam lobe, proceed to Step 1 of the Repair Procedure.
NOTE: Exhaust adjuster(s) are designed to be compressible. They will exert a reactionary spring
force during compression and return to full expansion without a compression force. If the exhaust
lash adjusters are shown faulty, follow normal service procedures. This bulletin is for replacing
the INTAKE lash adjuster(s) only.
REPAIR PROCEDURE:
1. Replace the HLAs on the intake side only of the cylinder head that the noise comes from. Refer to the
detailed service procedures available in DealerCONNECT/Service Library under: 09 - Engine, 3.6L /
Cylinder Head / Lifters(s), Hydraulic / Removal and Installation.
NOTE: Only replace the intake HLAs on the noisy cylinder head. Do not replace both sides.
2. Run engine and confirm noise is not present.
