Possible Causes

Worn valve stem seals, Worn piston rings, Overfilled engine oil, Turbocharger oil seal leak

Safety: Monitor oil level closely; do not allow engine to run out of oil.

Check oil level: Ensure oil is not above the maximum mark on the dipstick. Drain excess if overfilled.
Observe consumption: Track oil usage over several run hours. High consumption indicates internal wear.
Inspect breather: Check crankcase breather for blockage, which can increase oil carry‑over.
Seek engine specialist: Persistent blue smoke usually requires engine overhaul or turbocharger replacement.
