FAQ

Q1: Is this Rocker Arm Assembly a direct replacement for the Nissan K25 engine?
A: Yes, this assembly is specifically designed as a direct replacement for the Nissan K25 diesel engine. However, we always recommend cross-referencing your existing part number (13251-FY500) and visually comparing the part to ensure it matches your specific engine configuration.

Q2: What should I check before installing the new rocker arm assembly?
A: Before installation, inspect the camshaft lobes, pushrods, and valve stem tips for excessive wear. Ensure the rocker arm shaft is clean and free of debris. It is also critical to adjust the valve clearance (lash) to the manufacturer’s specifications after installation to prevent valve train noise and potential engine damage.

Q3: How long does shipping typically take for international orders?
A: Shipping times vary based on location and chosen method. For express air freight (DHL/UPS/FedEx) to major cities, delivery typically takes 5-7 business days. For standard sea freight, transit time is approximately 20-35 days depending on the destination port. We can provide a precise shipping estimate upon ordering.
