FAQ
Q1: Is this valve suitable for both intake and exhaust positions on the 3TNV84T engine?
A: This listing covers part numbers for valves used in the 3TNV84T engine. Engines typically use different part numbers for intake and exhaust valves due to material and design differences. Please consult your engine’s service manual or cylinder head diagram to confirm whether 129005-11100 or 129508-11100 is the correct valve (intake or exhaust) for your specific repair. Contact our technical team with your engine serial number for precise verification.
Q2: Do you recommend replacing valve guides and seals when installing this new valve?
A: Yes, as a best practice for engine overhaul, we strongly recommend inspecting and, if necessary, replacing the corresponding valve guides, valve stem seals, and valve springs during reassembly. This ensures optimal performance and longevity of the new valve and prevents premature oil consumption or compression loss.
Q3: What is the typical lead time for shipping to Europe or North America?
A: For standard container (LCL/FCL) shipments to major ports in Europe or North America, the sea freight transit time is typically 25-35 days, plus inland logistics. We offer expedited air freight options for urgent requirements, which can reduce delivery time to 5-10 business days. Our logistics team will provide the most efficient shipping solution based on your order volume and timeline.
