Common failures & inspection points

Turbocharger fouling from soot deposits: fouling and blockage from carbon deposits is the main cause of turbocharger surging. Contaminat

Regular cleaning (every 200-250 operating hours): water wash (routine), dry cleaning (stubborn deposits), chemical cleaning (overhaul with OEM-approved agents)

Cylinder head cover oil leaks: gasket wear (approx. 70% of all failures) due to embrittlement after approx. 5 years of operation. Also misalignment of cover (3 m

Visual inspection for oil stains around cylinder head; check for correct assembly and gasket aging; check oil level (overfill increases pressure)

Fuel injection system common rail: injectors can exhibit wear, coking and O-ring failure under high pressure load (1600 bar). Single solenoid ve

Inspectors should check for fuel leaks around injection lines; periodic injector testing and pressure testing recommended; overhaul per operating instructions

Connecting rod bearing wear and scuffing: insufficient lubrication under high pressure can lead to adhesive wear and microscopic welding. Excessive

Visual inspection for scratches, discoloration, embrittlement at accessible bearing points; oil pressure monitoring; inspections per service intervals

Cylinder liner and piston wear: wear is normally operational; critical are cold corrosion (when operating temperature not sufficiently reached) and the

Periodic cylinder cavitation testing; inspections during cooler operating phases; thermal monitoring of exhaust gas temperatures
