2. Coolant Leakage: A blown head gasket or cracked cylinder head can allow coolant to enter the combustion chamber, causing white smoke.
3. Worn Engine Components: Excessive wear and tear on the engine's internal parts, such as pistons, rings, and bearings, can lead to smoke due to increased oil consumption and blow-by gases.
4. Turbocharger Issues: If your vehicle has a turbocharger, a faulty turbocharger seal or other problems can cause oil to leak into the exhaust system, resulting in blue or white smoke.
5. Faulty PCV (Positive Crankcase Ventilation) Valve: A malfunctioning PCV valve can lead to excessive crankcase pressure, pushing oil past seals and causing smoke.
6. Transmission Fluid Leak: A leak in the transmission fluid cooler lines or a faulty transmission seal can allow transmission fluid to mix with engine oil, resulting in smoke.
7. Clogged EGR (Exhaust Gas Recirculation) System: A clogged EGR valve or EGR system can disrupt the flow of exhaust gases, leading to incomplete combustion and smoke.
