Common failures & inspection points
Inspect fuel pump drain line connection for flow blockage during operation; verify fuel viscosity maintained at 2-14 cSt at engine inlet; check for fuel sludge deposits in drain hole and barrel groove
Inspect turbocharger for deposit buildup on turbine blades; examine exhaust valve surfaces and combustion chamber for carbon deposits; verify L.O (lubricating oil) specification matches fuel sulphur content per manufacturer list
Monitor piston ring clearance and condition; inspect main bearing cap studs for looseness after each overhaul; verify hydraulic tightening force applied to underslung crankshaft support studs
Verify MGO temperature maintained at ~22°C to achieve 2 cSt viscosity; check fuel heater function for cold climate operation; test actual fuel viscosity at engine inlet before commissioning
Monitor boost pressure trending; inspect turbocharger exhaust seal condition during regular intervals; check compressor and turbine blade condition for foreign object damage; verify turbo oil supply/drain lines clear of sludge
