Hydraulic Valve Lifters

Bucket-type hydraulic lifters operate in sintered metal sleeves that ride in camshaft housing. Cam lobes depress lifters (which are oil filled under pressure, through internal passages). With hydraulic lifters, no valve clearance adjustment is necessary. Whenever lifters and sleeves are removed, mark components for reassembly reference.
