1. Coolant leak: If there is a leak in the cooling system, coolant can enter the combustion chamber and be burned along with the fuel. This can cause white smoke to come out of the exhaust.
2. Blown head gasket: A blown head gasket can also allow coolant to enter the combustion chamber. This can cause white smoke to come out of the exhaust, as well as other symptoms such as overheating and loss of coolant.
3. Faulty fuel injector: A faulty fuel injector can cause too much fuel to be injected into the combustion chamber. This can cause incomplete combustion, which can produce white smoke.
4. Worn piston rings: Worn piston rings can allow oil to enter the combustion chamber. This can cause blue or white smoke to come out of the exhaust.
If you are experiencing white smoke coming out of the exhaust of your Lincoln Town Car, it is important to have the vehicle inspected by a qualified mechanic. This will help to determine the cause of the smoke and ensure that it is repaired correctly.
