Too much smoke coming from car exhaust

Then after about seconds to a minute, the white smoke should clear up. If this is the case then you have nothing to worry about. In this case, bad seals or piston rings cause oil to leak into combustion chamber which then mixes with fuel and burns. The result is a white or light bluish smoke that comes out from exhaust manifold. Pay attention to what it needs to ensure more miles for your vehicle.

This will cause white smoke , along with the idle issue. Especially in a humid environment. I guess a lot of moisture gets inside the exhaust. Each engine has valves that open and close. These Valves are manufactured to open mechanically by pressure from a Rocker Arm.

They let air and gasoline come into the engine. If there is a problem within the engine that produces smoke , that smoke will exit the engine through the exhaust. A leaking valve cover gasket might produce smoke caused by oil dripping on a hot manifold.

One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant, it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust. Blue or gray smoke coming from the exhaust pipe. White smoke or water vapor coming from the tailpipe, especially in the morning when the engine is cold.

Black smoke or very dark smoke coming from the exhaust pipe. A new fuel odor or drop in MPG that seems to be coming from the exhaust pipe. This is nothing but steam caused due to condensation.

As the engine warms up after a few minutes, this white smoke will not be reduced because condensation is dissipated. It should reduce or even disappear after the car becomes reasonably warm. Some white exhaust smoke is normal, especially when you first start the car. Condensation can turn to vapor, providing what looks like white exhaust. But excessive white smoke likely means coolant is leaking into the engine combustion chambers.

The actual cause of the increased fuel consumption varies, but it is often fairly easy to diagnose. When a cold engine is starte it soon begins to heat up, and a byproduct of this is water. If thick, white smoke comes out the exhaust pipe, this can be an indication that there is too much oil in the engine. Taking the car to the mechanic immediately is important to minimize the likelihood of permanent damage being done to the engine block. If oil was pouring out the fill cap, it probably wouldn’t even run.

One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating. You’ll also notice that the exhaust is darker, particularly on large trucks with powerful diesel engines. The color of the smoke determines what system could be malfunctioning.

A small amount of smoke or steam from the exhaust pipe of the car is normal at start up or under power. Typically, once a vehicle starts producing smoke the pattern will continue until the engine is repaired. When white smoke is spewing from your exhaust , it is usually an indication that something is burning. The typical culprit is a burning fluid from the vehicle, but other causes are possible.

A backyard mechanic can diagnose the problem by observing and smelling the smoke. You can usually determine the problem in a few steps. This can be caused by a worn piston ring or rings.

Mine started misfiring, with new plugs. Why do some cars have more than others? Smoke came out the exhaust.

But even when the car had be driven for an hour, sit in traffic and it continued to plume. I suppose water vapour.
