Common failures & inspection points

Turbocharger fouling and carbon deposits

Inspect turbocharger for fouling/contamination; clean if necessary when high exhaust gas temperatures detected; check fuel quality for excessive sulfur content

Exhaust gas temperature imbalance between A-bank and B-bank (50–80°C difference)

Check Fuel Pump Rack Index for even distribution; verify Maximum Firing Pressure and injection timing; inspect fuel injectors and intake/exhaust valve condition

Piston ring damage and wear; top land deposit formation with incorrect lube oil BN balance

Inspect piston rings for damage/breakage; measure ring groove clearances; verify correct cylinder oil grade (BN balance); check for lacquering on cylinder liner surface

Cylinder liner scuffing from insufficient lubrication or contaminants; excessive corrosive wear with low-sulfur fuel + high-BN lube

Measure liner bore diameter at multiple points; inspect for scratches/burrs; verify crosshatch honing pattern; confirm correct lubricant viscosity and additives per specifications

Fuel injection nozzle coking and carbon deposits; fouled injectors reduce flow rate

Test fuel injectors with injection tester; check nozzle spray pattern; verify fuel quality and separator function; inspect nozzle tip for coke deposits
