Liqui Moly Kit for Hydraulic Lifter Noise and Valvetrain Wear – Engine Flush, MoS2 and Hydraulic Lifter Additive

Liqui Moly cleaning and treatment kit designed for maintenance services where the goal is to help reduce hydraulic lifter noise, improve internal engine lubrication, and reduce friction and wear in valvetrain components.

This package combines an internal engine cleaning treatment before the oil change with oil treatments added after the new oil is installed. It is a recommended option for engines with noisy idle, hydraulic lifter noise, or symptoms related to internal deposits and increased friction.

 Oil and oil filter are not included.

 Application

Recommended for 4-stroke gasoline and diesel engines, with or without turbocharger, as long as these additives are compatible with the vehicle specification and the type of engine oil used.

Compatible with most commercial motor oils. Always verify the engine oil capacity and the vehicle manufacturer’s recommendations before use.

Kit Includes

1- Liqui Moly Pro-Line Engine Flush – 500 ml

Part No.: 2037

Internal engine cleaner used before the oil change. Helps dissolve and remove deposits in the lubrication system, including oil passages, bearings, and piston ring areas.

2- Liqui Moly MoS2 Anti-Friction Engine Treatment – 300 ml

Part No.: 2009

Anti-friction engine oil treatment with MoS2 for use with new oil. Helps reduce friction, wear, and engine noise by providing a protective layer on metal friction surfaces.

3- Liqui Moly Hydraulic Lifter Additive – 300 ml

    Part No.: 20004

    Hydraulic lifter additive. Helps reduce hydraulic lifter noise, clean oil passages, and improve the operation of the hydraulic valvetrain system.

Technical Note

This kit is designed as a cleaning and treatment solution for the engine lubrication system. It should not be presented as a mechanical repair. If the noise is caused by severe wear, low oil pressure, a damaged lifter, internal engine damage, or another mechanical failure, the treatment may not solve the problem.

Not recommended for motorcycles with wet clutches.

Compatibility Note

Always verify the engine oil capacity and the vehicle manufacturer’s recommendation before use. For engines with oil capacity above 5 L, review the Engine Flush dosage before application.
