Common failures & inspection points

Methane slip in exhaust (100-3000+ ppm typical for lean-burn SI engines; Bergen designed B36:45 to minimize)
www.rolls-royce.com/media/press-rel...
Piston ring carbon deposits at TDC zone from high combustion temperatures in lean-burn operation
Turbocharger compressor wheel blade erosion and FOD (foreign object damage) requiring visual borescope inspection
www.marineinsight.com/how-variable-...
Fuel solenoid cut-off valve sticking or seal degradation (safety-critical for spark-ignited marine engines)
www.manualslib.com/manual/1458843/B...
Cooling water system corrosion from improper jacket water chemistry (pH, conductance, chloride, iron content critical)
