Black smoke means the engine consumes too much gas - possible problem with fuel injection, or you could have a bad fuel pump. I would recommend to check fuel pressure. Fuel injected cars are very fuel pressure sensitive. Fuel pressure is very important and must be within specifications! But if the pressure is low, it does not mean the pump is bad. A plugged fuel filter, a pinched line, and low voltage at the pump can contribute to low fuel pressure. Both must be checked before replacing the pump. U can get a fuel pressure gauge at a local auto parts store for cheap. I hope this helps and Good luck!

2000 Cadillac DeVille running rich city exhaust engine runs great uses boil it but doesn't burn have a blue oil leaves white smoke what could be the problem with it?


Running rich burns black smoke.

Burning oil, burns blue smoke.

Burning white smoke is steam and can be indicative of a damaged head gasket, or just weather conditions. Fuel contains water at molecular level.

Heavy exhaust smoke coming from tail pipes while sitting still or taking off. What's the problem


Is it black? black smoke means you are burning too much gasoline could be a bad choke or even a dirty air filter.
Blue smoke means you are burning oil out of your engine
.White means water getting into crank case or pistons.

I have a Mitsubishi challenger 2.8 turbo diesel Which just started smoking and when I leave sometimes the level counter is not picking up causing excessive smoke from the exhaust pipe.I don`t know what...


What is a "level counter"? I am not familiar with this terminology.
What colour is the smoke from your tailpipe? White: possible coolant leak/head gasket failure. Blue: Possibly running too rich or burning oil. Black: Burning oil

Black smoke leak power


Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
Check your EGR. it wil cause those problems.

I hope this helps; remember to rating this and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.

Chevy Prizm or Toyota Corolla 2000 valve cover gasket problem? Right after oil change, engine check light came on & car started smoking & losing oil. I took out all 4 spark plugs: they were in very...


The valve cover gasket isn't hard to change. Oil on the plugs indicates a more serious problem. Smoke from the exhaust would be from rings, rich mixture, worn valve guides. It may be that the engine is overfull (that would show on the stick). Oil loss from a leaking gasket would smoke under the hood and leave oil on the engine and the ground.

Black smoke coming out of exhaust, only on immediate acceleration. Leaves black spots on ground under exhaust pipe.


Your engine is running "too rich" meaning more gas is going into the chamber than is supposed to. If it is a late model, to need to see your mechanic. FYI , blue smoke is oil, black too much gas, white, antifreeze, (really bad).

A temporary solution for removing oil smoke. (oil burning )
Use synthetic oil with 3 cans of STP oil treatment with oil level brought only to the add mark on the dip stick.

The synthetic oil will burn clear and the STP will reduce the oil burning to almost 0 for a day or two.

To reduce antifreeze burning.......put a rad cap on that cannot hold pressure and is vented to the overflow bottle......rip the rubber gasket on the cap in two...leave half there.
This will cause no pressure to build up in the cooling system and should reduce antifreeze burning greatly.

REMEMBER.....if you have filled the exhaust system with a burning product....antifreeze or oil.....it will take time to burn off and out of the exhaust system.

These are temporary solutions just to get you through the test.
You may need major engine work to correct a smoking engine for long term use.
