SINOTRUK OEM-Compatible Engine Valve Seal – Model VG1560040032 | For HOWO Truck Diesel Engines
Ensure maximum engine efficiency and prevent excessive oil consumption with this genuine-specification valve stem seal (No de pièce. VG1560040032) , designed specifically for SINOTRUK HOWO trucks equipped with WD615, D10, and MC05/MC07 series engines. This critical engine spare part plays a vital role in maintaining proper lubrication balance while preventing engine oil from leaking into the combustion chamber — a common cause of blue exhaust smoke and reduced performance.
Manufactured using high-temperature resistant NBR (nitrile butadiene rubber) or optional FKM (fluoroelastomer/Viton®) material, le VG1560040032 valve seal withstands extreme heat up to 250° C, aggressive blow-by gases, and prolonged exposure to diesel fuel and oil contaminants. Its precision-molded design ensures perfect fitment on the valve guide, offering long-term sealing integrity under heavy-duty operation.
This part is widely used in Sinotruk spare parts maintenance programs, especially during mid-life engine services, injector replacements, or turbocharger repairs. It fits both intake and exhaust valves across multiple models including HOWO A7, A5, T7H, T5G, cement mixers, dump trucks, and logistics vehicles.
