Collapsed oil lifter

A hydraulic lifter is designed to ensure that there is zero clearance in a valve train. This leads to a quieter operation of the engine. In the majority of engines there is an adjusting nut on the rocker arm that can be turned to adjust the clearances between the valves and lifter. In many cases, hydraulic lifters have to replaced instead of adjusted. This may be the result of an active fuel management (AFM) lifter that is mechanically collapsed and/or stuck all of the time. This may be the result of internal locking pin damage in the lifter, due to oil aeration. This may be the result of a lifter that has collapsed and is stuck in the lifter bore.

A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device Oil under constant pressure is supplied to the lifter via an oil channel, through a small hole in the lifter body.

Hydraulic lifters can collapse, with no oil cushion to dampen the pounding from the tappet or push rod. Solid lifters can wear on their camshaft side, along with the camshaft lobes. Too much oil in the crankcase can cause oil aeration, or air bubbles, a condition when the crankshaft churns up the oil by direct contact. A bad lifter usually produces a unique sound. It’s just like a tapping sound with quick in rhythm rather than a ping or knocking sound. Depending upon how long does the noise persist after the starting of the engine, we can conclude whether the problem is with the valve train or dirt in the oil tank.
