SOURCE: power loss and black smoke?

I had a similar issue to this after I got in a VERY small fender bender (literally) in an 87 Turbo Supra. In my case, my pasenger fender got pushed in JUST enough to crack a charge pipe and cause a boost leak.

Basically, what was happening was the turbo would spool and build boost, the mass fair flow sensor would read all this air coming in and tell the ECU to dial up the the appropriate amount of fuel. When the air reached the cracks in the charge pipe, it would escape out of them. Thus there was a much lower air-to-fuel ratio, causing less fuel to combust, which lead to power loss and black smoke out of the exhaust.

My guess is either an oxygen sensor, or more likely a boost leak.

Good luck mate.

Subject:
Engine Coolant Loss with No Visible Leaks (Reseal Injector Sleeve)

Some owners may comment on engine coolant loss with no visible leaks. Excessive white smoke or a coolant type odor coming from the exhaust pipe, along with low coolant levels, may indicate coolant in the combustion chamber.
Cause
Condition may be caused by engine coolant entering the cylinder due to a dirty or damaged seal between the fuel injector sleeve and the cylinder head.

If it's black smoke, you could have a faulty or dirty EGR valve and may not be closing 100%. Remove the EGR valve and clean it with spraying carb cleaner and reinstall after inspecting the valve can move without any binding. Goo luck and hope this helps.

SOURCE: 2004 duramax black smoke and sputtering when

Black smoke means "fuel not being combusted" or "runnig rich". I have no doubt you have gasoline. Your spark may not be burning the gas. Is there a check eng lite? If EGR was sticking, you would probably get a check engine light for this. If your truck has a Vortec design, I would find out if you need a new "spider". What is your mileage? Are you due for a tune up? What spark plugs are you using? Vortec? "Not all the time" sounds like intermittent. When was the last time you changed the fuel filter? Can't hurt to change this. This would be the actaul starting point for me. I would change the fuel filter which is under the driver under the chasis. You will need a 16MM and a 20MM. USE ONLY LINE WRENCHES. You may need a fuel line disconnect kit too depending on your model. Notice it only happens on acceleration? that is when you are forcing even more fuel thru the system, but not enough of a fuel stream make cause sputtering and when the fuel comes thru too rich that would be the black smoke. It sounds like you have the 2 extremes. is there afuel regulator on your vehicle? If so, you may need to change that too. Good luck.

Why is my Kia sorento starting to blow out black smoke.? I have had no loss of power


Black smoke means you have too much diesel in the mix that is being ignited. This can be because either too little air is getting in or too much fuel is going in. First step (easy and cheap) is replace the air filter. If there's still smoke check the erg valve is clean and moves easy. If it's still there after that then check the common rail injectors for leakage.

Ford transit 110 T280 I've back smoke on excellaration and loss of power on inclines; could it be the EGR valve at fault ; also have management warning light on.?


Needs piston rings. You have lost compression so you are losing power. The oil is getting pasty the worn rings and entering the combustion chamber which would explain the black smoke and loss of power.
