What causes a crack in the tappet valve?

This is the reason why valve adjustment should be completed when the engine is as cold as possible. On the other hand, if the tappet adjustment is too tight, the valves can stay open slightly too long, meaning much more heat is transferred through to it than it’s designed to handle which can cause chips and cracks in the valve.

What does a tappet do in an internal combustion engine?

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. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower.

How do hydraulic tappets affect performance of a car?

Hydraulic tappets are automatically adjusting that have a plunger inside the main body. This plunger has a cavity that is charged with oil through a ball valve. The spring expands the tappet and takes up all the clearance. As the valve is lifted, the ball valve closes which retains the oil inside the plunger.
