This hammering manifests as a very noticeable tapping that increases in volume and frequency with engine rpm. A bad lifter will throw off the affected cylinder's ability to move and burn air and fuel, which will typically lead to spark plug fouling and a miss on that cylinder. Consequences A collapsed lifter puts a great deal of stress on a vehicle's valve train. Collapsed lifters can easily bend pushrods, which will subsequently fall out of the space between the rocker arm and the top of the lifter. Once a push rod falls out of the space, the very least you can expect is a dead cylinder. Worst-case scenarios include broken rocker arms, broken valves, cracked heads, a damaged cam or complete engine destruction.

## Features

- These lifters are used in all NON ''DOD/MDS'' They are not the same as the ''MDS'' lifters used in the DOD engines on some of the vehicles.
- Valve lifters play a key role in the valvetrain of pushrod engines. A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. The hydraulic lifter was designed to allow the valve train to operate with zero clearance—leading to quieter operation, longer engine life.
