Exhaust soot is Carbon based molecules that have not reacted to completion in the combustion chamber.
We input Hydrocarbon, Air, and Exhaust gas (EGR), and hope that we burn all the hydrocarbon into carbon dioxide and water. If there is not enough oxygen in the combustionchamber for the amount of fuel (through over allowance of EGR or otherwise) then we get soot paticles forming.
burning oil
No. This means that the manifold has an exhaust leak.
engine tune just a major service then maybe a new exhaust system
If you have an issue with furnace exhaust in your home and soot is exhaust. Please stop wasting your time here. That is dangerous. Call somebody! Nobody here can tell you what it is with out looking at it.
either its running to lean or you have a bad exhaust valuve
burning oil
A running Diesel engine releases soot in its exhaust. Another word for soot is particulate pollution - as soot consists of small particles.
"Catalytic Converter" not cadillac, lol. The black liquid is carbon soot mixed with water from condensation in your exhaust. The carbon soot is from the oil that lubricates your engine, it also gets small amounts in the combustion chamber, thus when your fuel/air mixture ignites in the (combustion) chamber, the oil (with carbon in it) is burned off and exits with the exhaust.
A chalky gray is a good sign that evrything is running well. Heavy black soot would indicate a rich condition, not good.
soot
The name is soot.
Soot is often produced when burning wood.
