Safety first: Monitor oil level closely; do not allow it to drop below minimum.

Check oil level: Ensure oil is not above the maximum mark; drain excess if necessary.
Inspect breather system: Check crankcase breather for blockage that could force oil into intake.
Observe turbocharger: Look for oil in the compressor housing or intercooler piping.
Plan engine inspection: Persistent blue smoke indicates internal wear and should be evaluated by an engine specialist.
