White smoke coming from the exhaust of a vehicle is almost always burning radiator fluid. Go in to a local shop and have them drain the oil and check it for any sign of water. If you are a DIY kind of person, drain the oil into a clear sided bucket and check to see if there is any separation in the fluid(oil is heavier so water will rise to the top).
If it so happens that you have water in your oil the most likely culprits are cracked cylinder heads, or a blown head gasket.

Hi I have a 1997 cadillac eldorado 4.6l northstar engine. It went from normal to blows clouds of smoke out the rear exhaust. Run sluggish.


clouds of smoke out the rear exhaus ,What color ? blue smoke is oil , white smoke is most of the time coolant is getting into the engines cylinders , Black the engine is running rich ,too much fuel . DTC P0135 HO2S Heater Performance Bank 1 Sensor 1
DTC P0147 HO2S Heater Performance Bank 1 Sensor 3
DTC P0340 IC Module Cam Reference CKT No Frequency
DTC P0401 Exhaust Gas Recirculation (EGR) Flow Insufficient
P0441 has nothing to do with the gas cap !
DTC P0441 Evaporative Emission (EVAP) System No Flow During Purge
DTC P1441 Evaporative Emission (EVAP) System Flow During Non-Purge

P0441 & P1441 will be back , may take a day or two , but will be back because gas cap has nothing to do with it .

Honestly , you should take your vehicle to a qualified repair shop !

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust


What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

WHY DOES MY 1996 GALANT BLOW OUT A HUGE CLOUD OF SMOKE WHEN I START IT THEN GOES AWAY IM USING A TON OF OIL


Hi Joseph, I'm glad to help!

When engine get a lot of miles on them the seals get hard and bridle and allows oil you slip by and it goes out the exhaust in at cloud of smoke. Here's a way to see if it is you "Valve Seals". When your driving it usually clears up and you have no smoke. Here's what you need to do after driving the car and it has cleared up, pull into a parking lot and let it sit and idle for 3 minutes. If a cloud of smoke comes out of the tailpipe when you take off, then you have bad "Valve Seals" and they will need to be replaced. Hope this helps and have an awesome day Joseph.

I have Hyndia Tucson 2006 Deisel. I have a problem in it. This problem is smoke heavily (Black) and there is no intention of any force during press the accelerator.


mean there might be fuel leaking into the engine or the air to deisel ratio is and not atomised correctly. the main causes are normally is the air filter that isnt allowing air into the engine. Fuel filter can also be at fault not allowing enough fuel in or allowing to much in the engine sometimes. This causes the chamber to burn it out. Fuel injector if fualty could allow to much fuel or not enough. My personal suggestion would be to run fuel injector cleaner first, then change the air filter. If that doesn't fix it change the fuel filter. I would go the cheapest route first. Is is prolly something simple

White smoke from exhaust


If you are getting clouds of white smoke out the exhaust it is a good indicator of antifreeze getting into one or more of the cylinders. I bought a "Great" car sight unseen from a friend once and when he pulled in the drive the whole car disappeared in a cloud of white smoke that only left when he shut the engine off. I found head gasket leaks in half the cylinders. It takes very little coolant to cause the white smoke. If you are absolutely sure of zero coolant loss perhaps the smoke is a little blue--an indication of burning a little oil from a sloppy turbo bearing. Try the nose test-- it may give you the answer. Burning oil has a distinctive smell.
