ADJUSTER Valve Lash Customer's complaint may include a ticking noise coming from the engine.
Read full bulletin
Technician's observations can refer to spongy or stuck hydraulic lash adjusters. Exhaust lash adjusters found with a "spongy" condition (compressible plunger) leading to the assumption of being defective/malfunctioning. EXHAUST lash adjusters are designed to be COMPRESSIBLE by hand. Intake lash adjusters found with a stiff or stuck condition (non-compressible plunger) leading to the assumption of being defective/malfunctioning. INTAKE lash adjusters are designed to be NON COMPRESSIBLE by hand. Do Not Replace EXHAUST lash adjusters when the following condition is present: should be compressible, but they will exert a reactionary spring force during compression and return to full expansion without a compression force. Do Not Replace INTAKE lash adjusters when the following condition is present: should feel very firm and difficult to compress. Once the correct functioning of the intake and exhaust lash adjusters is validated with the procedure above, refer to the Service Manual "HYDRAULIC LIFTER(S) NOISE DIAGNOSIS" procedure. After the corresponding service procedures from the Service Manual involving the Lash Adjusters have been conducted, refer to the detailed instructions in the Service Manual to diagnose and/or service any other component.
