Yes, blue smoke from the exhaust and a burning oil smell are common indicators of internal oil burning in the Changan Karvaan. These signs suggest that engine oil is leaking into the combustion chamber and burning along with the fuel. This issue is often caused by worn piston rings, valve seals, o r a faulty PCV system. If these symptoms appear, its important to monitor oil levels and have the engine inspected by a mechanic to prevent further damage.
