Kohler-SDMO Oil Burning / Internal Engine Wear

Blue smoke from exhaust and rising oil consumption

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn piston rings, Valve stem seal wear, Turbocharger oil seal leak, Overfilled crankcase

Safety first: Monitor the oil level closely and avoid overfilling. Operate in a ventilated area.

Check oil level: Ensure the oil is at the correct level; drain excess if above MAX.
Inspect breather: Check the crankcase breather for blockage that could force oil into the intake.
Turbo inspection: Inspect the turbocharger (if fitted) for oil in the compressor outlet and intercooler piping.
Record consumption: Track oil usage over operating hours. High consumption indicates internal wear and the need for an engine overhaul.

Blue smoke is typically not fixable without internal engine work; schedule service with a diesel specialist.
