1. 1:1 OEM precision mold, completely matches bolt holes, cooling water passages, oil return galleries and intake/exhaust runner layout of 4TNE98 engine, zero assembly deviation
2. MLS multi-layer metal laminated design bears severe combustion temperature and pressure in long-time heavy load operation, effectively prevents gasket blowout, cylinder gas blow-by, coolant and engine oil emulsification mixing
3. Excellent anti-aging and anti-corrosion performance, stable sealing effect under dusty, high-temperature construction working environment, extend engine service life and reduce breakdown rate
4. Core matching spare part for full 4TNE98 overhaul gasket kit, can be assembled with valve stem oil seals, crankshaft front/rear oil seals, injector O-rings for complete top-end engine rebuild

This 4TNE98 cylinder head gasket is the most critical sealing component installed between cylinder head and cylinder block of Yanmar four-cylinder industrial diesel engine. It separately seals four combustion chambers, cooling water channels and lubricating oil passages, isolates high-pressure exhaust gas, antifreeze coolant and engine lubricating oil to avoid cross leakage. It solves common faults including engine overheating, insufficient power, white smoke emission, difficult starting and diluted engine oil, and must be replaced during cylinder head disassembly and major engine maintenance.
