AnswerThere are several possible answers to what makes a car smoke. If the smoke is blue-black the engine is burning oil. This could be caused by worn rings or valve guides. If the smoke is gray black it is caused by a to rich gas mixture. This could be caused by a malfunctioning choke or injector, oxygen sensor, or other fuel related equipment. If the smoke is gray white it could be a blown head gasket or cracked block, allowing coolant to get into the exhaust system. Other causes of smoking could be an oil leak that is dripping on to the exhaust pipe or muffler.

Water is in your engine. Check intake and head gaskets.

An Rx7 is a model of a car that Mazda makes. All cars can smoke lightly through the exhaust system. If the smoke that is coming out becomes excessive or black consult a mechanic.

Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.

from smoke from car, train exhaust, smoke from refuse burning

To be damaged by smoke you need to actually inhale the smoke, so it there is smoke still lingering in the air of the house or car then YES. If however the smoke has cleared entirely then NO.

Blue smoke = excessive motor oil. Black smoke = excessive fuel. White smoke = engine coolant

the smoke comes out the rear of the car in a pipe. the smoke comes out only when the engine is on. you do not have to be moving to have smoke come out. just the fact that the engine is on creates smoke due to the byproduct of the fuel and energy.

When you smoke your teeth do go yellow and fall out gradually.

Smoking all the time is probably the piston rings. Smoking when you first start it is probably the valve seals. Smoke may be coolant and not oil which would mean a head gasket, cracked head or block. What color smoke makes a difference. Black smoke, to much fuel (flooding). Blue smoke, engine oil. White smoke, engine coolant.

Car smoke or exhaust contains many toxic chemicals that are harmful to health and the ozone layer. The major chemical in car exhaust is carbon monoxide.

When a car begins belching smoke, it is probably burning excess oil or gas. It is likely that a seal is leaking in the engine.

Examples are: Littter, gas from a car, factory smoke, smoke....

Black smoke from an engine is caused by unburnt fuel.

The color of the smoke will help identify the problem. Blue smoke is engine or transmission oil. Black smoke, excess fuel. White smoke, engine coolant.
