FAQs

What is a hydraulic tappet?

A hydraulic tappet, also known as a hydraulic lifter, is a component in an internal combustion engine's valve train. It is a self-adjusting device that sits between the camshaft and the valve, designed to automatically maintain zero clearance or valve lash. This ensures quiet operation, reduces wear, and optimizes engine performance by compensating for thermal expansion and component wear.

What is the function of a tappet in an engine?

The primary function of a tappet is to transfer the rotational motion of the camshaft into the linear motion required to open and close the engine's valves. Hydraulic tappets perform this function while automatically adjusting their length to eliminate any gap between the tappet and the valve stem, ensuring consistent valve timing and eliminating the noise associated with valve lash.

What are the symptoms of a bad hydraulic lifter?

Common symptoms of a failing hydraulic lifter include a distinct ticking or tapping noise emanating from the engine, particularly at idle, which is caused by excessive lash it can no longer compensate for. Other symptoms can involve engine misfires, loss of power, poor fuel economy, and excessive exhaust smoke due to improper valve operation affecting combustion.

What is the difference between mechanical and hydraulic lifters?

The fundamental difference lies in adjustment. Mechanical lifters (or solid lifters) require manual adjustment to maintain the correct valve lash clearance at specified intervals. Hydraulic lifters are self-adjusting, using engine oil pressure to automatically maintain zero lash. Hydraulic lifters offer quieter operation and less maintenance but can be more complex and susceptible to issues from dirty oil.

How does a hydraulic valve lifter work?

A hydraulic valve lifter works via a piston and plunger assembly housed inside its body. Engine oil under pressure is fed into this assembly. The oil pressure acts on the plunger, taking up any clearance between the lifter and the valve stem. A check valve traps the oil inside the lifter, making it a solid unit that pushes the valve open. A small amount of oil can leak down over time, allowing the lifter to adjust to wear.

What causes hydraulic lifters to fail?

Hydraulic lifter failure is commonly caused by contaminated or old engine oil, which can clog the small internal passages and the check valve within the lifter, preventing it from filling with oil and maintaining pressure. Lack of proper lubrication, using the incorrect oil viscosity, excessive engine wear producing metal debris, and simply reaching the end of the component's service life are other primary causes of failure.
