Common failures & inspection points

Fuel injection pump sticking due to low viscosity MGO fuel below 2 cSt causing reduced lubricity and hydrodynamic film breakdown

Verify fuel supply viscosity (maintain 2-14 cSt). Inspect fuel pump drain line for clogging by fuel oil sludge. Monitor drain hole/groove inside barrel.

Excessive carbon deposits in combustion chamber, exhaust gas ways, and turbocharger when operating continuously with low sulfur fuel (below 100 ppm sulfur conte

Inspect combustion chamber deposits via borescope. Visually inspect turbocharger inlet/outlet for deposit accumulation. Check exhaust manifold for buildup.

Piston ring blow-by caused by hard carbon deposits cementing rings in grooves, restricting seal ability and reducing cylinder compression

Measure crankcase pressure for blow-by indication. Inspect piston rings for freedom of movement. Check cylinder compression via pressure test.

Cylinder liner scuffing/wear from improper metallurgy or poor manufacturing, leading to piston and piston ring damage

Measure cylinder liner wear (limit 0.4 mm). Inspect flame ring wear (limit 0.2 mm). Perform borescope inspection for scoring/scuffing marks.

Main and connecting rod bearing wear exceeding limits, requiring shell replacement if thickness drops to 4.925 mm or less

Check main bearing and connecting rod bearing clearances at major overhaul. Measure thrust bearing axial clearance. Verify shell thickness specifications.
