What to do if your engine valve lifter is tapping?
Mega Power is a leader in automotive care and problem-solving products. If you’re having an engine valve lifter tap, caused by the above negatives, this review introduces the best of those new types of products made to end the tapping.
What causes lifter valves to open and close?
The oil inside pushes the rocker arms further away from the camshaft, which causes the valves to open further. Oil pressure failures are usually at the root of lifter tapping, also known as lifter collapse.
Do you need to adjust the lifter on an engine?
If your engine uses adjustable rocker arms, you may need to simply adjust them to obtain the proper clearance (aka valve lash). However, most modern engines use a non-adjustable valvetrain where a properly-functioning hydraulic lifter or lash adjuster keeps the valvetrain running with zero clearance.
Where is the tappet located in an overhead valve engine?
However, a tappet (also known as a cam follower or lifter) is a small cylindrical mechanism which is attached to the end of the pushrod(in overhead valve engines) or the rocker arm (in overhead cam engines).

How does a hydraulic lifter work on an engine?
The pushrods actuate the rocker arms, which open the valves. Hydraulic lifters allow the valve lift to increase with engine rpm by filling up with oil as the oil pressure rises. The oil inside pushes the rocker arms further away from the camshaft, which causes the valves to open further.
