Using engine oil pressure, it automatically compensates for valve clearance, helping maintain smooth, quiet and efficient engine operation without regular manual tappet adjustment.

Confirm compatibility with the engine specification and original part number before ordering.

What Does It Do?

The hydraulic lifter automatically maintains the correct valve clearance using engine oil pressure.

This helps the camshaft operate the valves accurately while reducing mechanical noise and unnecessary valve train wear.

Why Does It Fail?

Common causes include:

• Contaminated or ageing engine oil
• Blocked internal oil passages
• Insufficient oil pressure
• Internal wear or sticking mechanisms
• High mileage and prolonged engine use

When Should It Be Replaced?

Replace if the lifter is worn, seized, damaged or no longer maintains correct valve clearance.

Common symptoms include persistent tappet ticking, excessive valve train noise and uneven engine operation.

Checks & Diagnosis

Check engine oil level, condition and pressure before replacing the lifter.

Inspect the camshaft and associated valve train components for wear. Confirm that the noise originates from a faulty lifter rather than another engine component.

Follow Porsche workshop procedures when installing replacement tappets.
