SDMO Oil Burning / Internal Engine Wear

Blue smoke from the exhaust and noticeable engine oil consumption on the SDMO standby generator.

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, Overfilled engine oil level, Turbocharger oil seal leak

Safety first: Monitor the oil level closely and avoid running the engine if the oil level approaches the minimum.

Check oil level: Ensure oil is not overfilled, as this can cause oil to be drawn into the intake. Drain excess oil if above the maximum mark.
Inspect breather system: Check the crankcase breather for blockage. Clean or replace as necessary.
Monitor consumption: Record oil usage over several run hours. High consumption indicates internal wear.
Plan major service: Internal engine repairs (rings, seals, turbo) should be performed by a qualified engine technician.
