Valve Lash (Clearance) Adjustment

Print

All engines are equipped with hydraulic valve lash adjusters. No periodic valve lash adjustment is necessary.

All vehicles have hydraulic valve lifters and require no adjustment. On these vehicles there will be a sticker under the hood indicating hydraulic lifters.

All engines covered herein are equipped with hydraulic cam followers, which Do NOT require clearance adjustment. If a 'ticking' noise is heard from the cylinder head while the engine is operating, the cause is usually air or small particles trapped within the cam followers themselves. This prevents oil pressure inside the follower, and causes the 'ticking' sound. In some cases, an engine 'flush' treatment can cure this annoying problem. If a hydraulic lifter (or multiple lifters) fails to quiet after an engine flush treatment, it may need to be replaced.
