1. 1:1 OEM precision die-cut, perfectly matches bolt holes, water jacket passages, oil return holes and intake/exhaust runner layout of 4TNV84 engine, direct installation without modification.
2. Reinforced cylinder bore sealing edge improves anti-burst performance, effectively prevents cylinder gas blow-by, coolant leakage and oil-water emulsification under long-term heavy load working conditions.
3. Good compression resilience and thermal insulation, stable sealing performance under continuous high temperature operation, effectively extend engine service life and reduce maintenance times.
4. Single matching part for complete 4TNV84 engine overhaul gasket kit, can be assembled with valve stem seals, crankshaft front/rear oil seals and injector O-rings for full top-end rebuild.

This 4TNV84 cylinder head gasket is the critical sealing component sandwiched between cylinder head and cylinder block of Yanmar 4-cylinder industrial diesel engine. It separates four combustion chambers, cooling system and lubrication system to avoid cross leakage of high-pressure exhaust gas, antifreeze coolant and engine oil. It solves common faults including engine overheating, power drop, white smoke emission, difficult cold start and engine oil dilution, which must be replaced during cylinder head disassembly and major maintenance.
