SOURCE: Lots of black smoke, not the best power

Check the breather filter, a quick test is pull the oil dipstick and rev engine if oil rises up dipstick replace breather filter straight away as it will blow engine if not

SOURCE: 2004 Ford F-350 6.0 Turbo Diesel - Severe Hesitation at Take Off

Some of these engines have a place to drain water out of the fuel system.. Some fords actually have a stick under the hood that you push or pull That opens a valve on a water collection bowl. It's not labeled usually. It might state where it is in the owners manual under fuel water drainage or something similar.. if that bowl is full it will cause hesitation... If it gets over full it will cause runability problems. Another possibility since you said it's black smoke is one of your injectors is sticking at low rpms and squirting raw fuel into the cylinder till the rpms get up enough to burn that fuel off completely then then the injector works a little better.... Do you notice any missing... Feel something under the hood like the air cleaner housing and make sure the vibration is constant and doesn't have a small sudden shake and the n smoothe... And then a small sudden shake again.
If it does have this shake you can trouble shoot which injectors by with the engine running loosening an injector line and seeing if the engine runs worse or not.. If it runs worse tighten it up and move to the next line till you unscrew one and feel and hear no difference... When you find that one that's the injector with the problem.

SOURCE: smoke is coming from the dipstick, 6.5L turbo diesel

Sounds like you have a clogged PCV valve thats the valve that lets the gases that get into the crankcase be rerouted back into the intake. It's silver about two inches and is usually in a rubber fitting in the valve cover and will have a hose on the other end. it's no tools installation just pull the hose off pull it out and replace with a new one. thats the first thing i'd do - 10 mins and 10 bucks should do it

SOURCE: mazda 6 2o diesel replaced turbo new unit same

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.

My 1992 nissan terrano blows to much black smoke .how to fix this .some say i have unbirt fuel?


if diesel and turbo , check turbo operation of for holes in the intercooler
if turbo or naturally aspirated check/ replace injector tips as black smoke indicators squirting and not atomizing
if petrol check for excessive fuel pressure, faulty injectors , leaking injector seal
regardless of petrol or diesel --black smoke indicates incorrect air / fuel ratio ( too much fuel) so injectors, intercooler, bad turbo or blocked air cleaner are all candidates for the fault

No power black smoke 2001 6.6 duramax


There are many reasons for black smoke. This color indicates incomplete combustion of the diesel fuel. Possible injector or injector timing problem would be the first thing to look at. Other causes can be a defective turbo... air restriction... engine running too cold... internal issues to name a few

I got a tata 407 turbo but the performance is poor it also smokes black and the fuel is black can some please help


Best I can tell this is a diesel truck? I know diesel, but
depending on age could be injectors, possibly Diesel injection pump hopefully not. The fuel is black? Someone is putting old engine lubricating oil in the fuel tank. It will increase the problem of black smoke. It may also have a bad smell because of the engine oil. If the turbo is not spinning properly (high pitched whine) the bearings may be bad and it's not getting enough air into the engine. This would also explain the smoke problem. Take it to a Diesel specialist!

Twin turbo 80 horse power deutz Diesel engine blows black smoke under load


Diesel engines smoke when under a heavy load. Unlike a gas engines, a diesel engine uses fuel that is more like an oil.Smoking is a good indication the fuel is not completly burning because of loaded engine spee. White smoke indicates the fuel is not ignitingefficiently. Truck, boats, tanks abd anything else using diesel fuel will smoke when it gets more fuel than it can use.. Easing up on the throttle will lessen the smoke but not eliminate.. Of coarse if the demand is lessened by applying less loadyhe fuel consumption drops.Not to worry as long as the smoke doesn't attract the EPA.

Jaguar x 2.0 Diesel Problem no power alot of black smoke coming out as you drive , now i have oil on rad and all over battery


run fault codes and look for EGR valve and pcv valve faults. Black smoke is unburnt diesel so it may be the injectors need attention. If it is a turbo then check the oil lines to the turbo and check turbo operation as it may not be producing air pressure for the engine.

Black smoke under acceleration that comes and goes. Have changed mass air flow sensor and did not help. Model is 2005 six speed turbo diesel


Black smoke indicates you are running rich. You may have to address the fuel injectors to make sure one is not stuck open. After replacing the MAF censor this would be my next step. Also your turbo seal might be leaking causing your truck to run rich throwing off the o2 censor. Also you can get black smoke from turbo blowby. Not burning oil but actual oil passing the rear turbine seal and getting into the exhaust. This should give you a few good places to check out. Good luck to you.

Welcome to the world of diesels....

Black smoke is produced when too much fuel is injected into the cyl. There could be several issues here, but I would start with running a diagnostic on your O2 sensors and MAS/MAP sensors.

I hope this helps
