Lifter / Lash Adjuster, Valve

Hydraulic lifters

Note:
^ Replace faulty hydraulic lifters complete only (lifters cannot be adjusted or serviced).

Check condition
^ Determine clearance between cam lobe and lifter.
^ If clearance is greater than 0.2 mm, replace lifter. If clearance is less than 0.1 mm or no clearance exists, then proceed with check as follows:





^ Push lifter down lightly with a wooden or plastic wedge. If when lifter is pushed down a 0.2 mm thick feeler gauge can be pushed between camshaft and lifter, lifter is to be replaced.

Note: When new lifters have been installed the engine must not be started for about 30 minutes. Hydraulic compensation elements must settle (otherwise valves will strike pistons).
