How do lifters work?
Your vehicle’s lifters actuate both the exhaust and the intake valves. The cam is equipped with egg-shaped lobes that allow the engine lifters to move upward and downward. As the heel of the cam is the wide and short end of the lobe, the cam moves. That movement creates little pushes that cause the engine lifters to go up and down. The engine lifters move the valves into a closed as well as open position. For a vehicle that has a non-overhead cam engine, the lifters move a push rod downward and upward. This in turn moves the rocker down and up as well. The front of the rocker then moves the valve.

Why do hydraulic lifters have holes?
Hydraulic lifters have a small hole in the cylinder body to allow oil inside the unit. Oil is virtually non-compressible, so it is perfect for hydraulics. Dirt in the oil–usually caused by poor maintenance–restricts the free flow of oil. It can even clog the lifter hole. Without enough oil in the lifter, you will hear metal on metal tapping–especially on start-up. Get the motor hot, drain the existing oil, fill the motor with new oil, and take it for a drive. Quite often magic occurs, and the tapping will have disappeared.
What is the space between a solid lifter and a rocker arm?
Solid Lifters. Solid lifters have a small space between them and the rocker arm–around 10/1000th of an inch. (The space is necessary to prevent motor parts from binding as they expand as the motor heats up.) This gap is known as valve lash, which when not adjusted properly, leads to lifter noise.
