Description
Hydraulic clearance compensation: Integrated with hydraulic tacks, it automatically eliminates valve clearance, ensuring the engine operates quietly throughout its life without the need for manual adjustment.
High-precision lever: Precisely transmits the movement of the camshaft to the valves to control intake and exhaust.
Support for VVEL system: On the VQ37VHR engine, it works in coordination with Nissan's renowned VVEL (Variable Valve Lift Electronic Control System) to achieve stepless adjustment of valve lift, which is the key to its outstanding power and fuel consumption performance.
Common faults and symptoms
The cause of the malfunction: After long-term use, the internal wear of the hydraulic tappet or the blockage of the oil passage has led to the inability to establish pressure normally.
Typical symptoms
When the engine starts cold, there is a clear "dada dada" abnormal sound (which may be alleviated after the engine is warmed up).
The engine power decreases and fuel consumption increases.
In severe cases, it may cause inaccurate opening and closing of the valves, leading to shaking.
The meaning of high quality
Choosing the "high-quality" 24170-27001 means:
Material guarantee: Made of high-strength alloy steel, the key friction surfaces undergo high-frequency quenching or nitriding treatment, ensuring extremely high wear resistance.
Precision manufacturing: The internal fit clearance of the hydraulic tappet is precise, ensuring stable oil pressure.
Perfect compatibility: The size is exactly the same as the original factory parts, ready to use immediately after installation, without affecting the functions of the VVEL system.
