Excessive blue smoke from exhaust during running

Safety first: Monitor oil level closely and avoid extended operation if oil consumption is high.

• Check oil level: Ensure oil is not above the maximum mark on the dipstick. Drain excess if overfilled.
• Inspect breather system: Check crankcase breather for blockage, which can force oil into intake.
• Observe smoke pattern: Blue smoke mainly on startup may indicate valve seals; continuous smoke suggests rings or turbo.
• Plan overhaul: Persistent blue smoke with rising oil consumption usually requires engine or turbocharger overhaul by a specialist.
