Assuming this is a gasoline engine, it is running rich from excess gasoline.
Black smoke is a symptom of an overly rich fuel/air mixture.
on the left hand side of the motor on the wall should have a 3 prong black cord in it
Excess fuel causes black smoke.
how can i get black exhaust smoke stuck on my dual exhaust
black is excess fuel
carbon result of incomplete combustion.
Need to know why this is necessary.
black smoke is usually a sign of bad piston rings, meaning they arent sealing correctly, and meaning that they need replaced which means a total engine rebuild basically.
Bad engine coolant sensor. Bad fuel injector. Plugged air filter.
Water and carbon are byproducts of combustion. Its all good...
If it's the inside of the exhaust that's black it could be caused by burnt oil in the engine.
It usually means too much fuel or not enough spark.
The plug should have a black cap on it, and be located on the passenger side near the oil filter. This is for diesel engines. The power cord must be purchased, and screws in. This info per Dodge dealer, but not verified yet.
Blowing black smoke is indicative of an oil leak in the engine.
they have elected a pope? in cold weather it is normal to see white smoke coming out of your tailpipe. the one you have to worry about is the black or the blue smoke
possibly needs a new carborator
AGE and engine failure
Catalytic converters clog due to the carbon that the car produces. Usually, when the carbon has built up inside the cat., black smoke will come out of the tailpipe when you rev the engine. In extreme cases, black soot is visible on the ground next to the vehicle's tailpipe. Crystal Woll
Behind the accumulator sticking out from the firewall about 3/4" on the passengers side. It is a little black stub. Really hard to see but you can get to it from up top if you are flexible.
probably a blown head gasket
running too rich check the air filter could also be defective injectors
bad rings or really bad valve seals.
black smoke means your burning oil and the head gasket will go sometime soon
You can stop your 7.3L from blowing black smoke by verifying that it is burning fuel cleanly and make sure the fuel mix is not too rich. You can also verify that it is not burning any oil.
