1. Coolant Leak: Check for leaks in the cooling system, such as a damaged radiator or hose.
2. Head Gasket Leak: If the head gasket is leaking, it can allow coolant to enter the combustion chambers, causing white smoke and a sweet smell.
3. Burning Oil: If the engine is burning oil, it will produce blue-white smoke and a burning oil odor. Check the oil level and condition.
4. Transmission Fluid Overfill: Overfilling the transmission fluid can cause fluid to leak onto the exhaust system, resulting in white smoke and a burnt smell.
5. Faulty PCV Valve: A faulty positive crankcase ventilation (PCV) valve can cause oil vapors to enter the intake system, leading to white smoke and a burning smell.
6. Exhaust System Problem: A damaged catalytic converter or exhaust component can cause unusual odors and smoke.
7. Condensation: Sometimes short-distance driving, especially in humid conditions, may lead to condensation in the exhaust system. After some driving, the condensation evaporates, causing white smoke.
Note: For safety, have your vehicle diagnosed and repaired by a qualified mechanic if you're concerned about the smoke and odor.
