Operasi dan Fungsi

The hydraulic valve lifter is a critical component in your Porsche engine's valve train. Its primary function is to maintain zero valve lash, which is the small gap between the valve stem and the rocker arm or camshaft lobe. By using engine oil pressure, the lifter automatically adjusts its length to compensate for thermal expansion and wear, ensuring quiet operation and precise valve timing.

A properly functioning hydraulic lifter contributes to:

• Reduced valve train noise (e.g., ticking sounds).
• Optimal engine performance and efficiency.
• Extended lifespan of valve train components.
• Consistent engine power delivery.

• Penukaran Minyak Biasa: Follow your Porsche's service schedule for oil and filter changes. Dirty or degraded oil can clog lifter passages, leading to malfunction.
• Use Correct Oil: Always use engine oil that meets Porsche's specifications for your vehicle model.
• Pantau Tahap Minyak: Regularly check your engine oil level and top up as needed to prevent low oil pressure, which can affect lifter operation.
• Dengar Bunyi Luar Biasa: A persistent ticking or tapping sound from the engine, especially after warm-up, can indicate a failing hydraulic lifter.
