Common failures & inspection points
Piston cooling nozzle blockage/misalignment: Gasket residue and combustion deposits can clog cooling nozzles, leading to piston crown overheating, expansion, an
Scavenge space fire risk: Blow-past from defective piston rings or worn liners allows combustion products/oil into scavenge space; leaking air cooler can raise
Exhaust valve seat erosion/regression: High combustion temperatures cause valve seat wear; internal clearances tighten as seats erode, reducing flow and increas
Fuel injection nozzle coking: Poor fuel quality and high combustion temperatures cause deposit buildup in injector holes, reducing spray pattern and combustion
