1. Blown head gasket: This is a common cause of white smoke, especially when coupled with antifreeze odor. If the gasket between the engine block and cylinder head fails, coolant can leak into the combustion chamber, leading to smoke and reduced engine performance. Repairing a blown head gasket can be a complex job and it's best to seek help from a qualified mechanic.
2. Cracked cylinder head: In some cases, a crack in the cylinder head can also cause similar symptoms, including white smoke, coolant loss, and engine vibration. If this is the issue, it might require a replacement of the cylinder head, which is a significant repair.
3. Coolant leaks: Other coolant leaks, such as a faulty radiator, heater core, or damaged hoses, may also cause white smoke. Check for any visible leaks and ensure there's no obvious coolant loss from the radiator or any connecting points.
4. Mass air flow sensor issue: While disconnecting the mass air flow sensor leads to reduced engine shaking, it doesn't necessarily mean the sensor itself is the root cause of the problem. The mass air flow sensor helps regulate the air-fuel mixture in the engine, and its failure can indeed affect performance. However, its dysfunction wouldn't usually result in white smoke or an antifreeze smell.
To properly diagnose the issue, it's recommended that you take your vehicle to a trusted mechanic or auto repair shop. They should be able to accurately identify the problem and recommend the necessary repairs or maintenance to resolve the smoking, shaking, and antifreeze odor issues. Ignoring this problem can lead to more significant damage and costly repairs in the future.
