SOURCE: 1.5 diesel. Blue smoke, not

Not sure what you mean by "heavy on diesel".   Most diesels, except for late models say 2005 or newer, will have a tiny amount of smoke when cold.  It's hard for a cold motor to combust diesel without a little smoke.  
My money would be on one or both of the other two injectors, dirty, dripping or bad spray pattern.  If you near anything lke a small city, you may be able to find a shop that has the abilty to clean and check them. I use a big marine diesel shop, RPM, in Ft Lauderdale, they can generally get injectors back to new for cheap (maybe $30 each) and have a big expensive high tech machine to test them (they can afford to, they use them for engines on million dollar yachts, among others).  The hyundai injectors might be cheap, the Bosch ones are not.
Injector cleaner in a can that the parts store is happy to sell you, has not worked for anyone I know.   
If you ever lay the car up (e.g. go away on holiday for a month so) put additive in the diesel to keep bacteria from growing in it.  If you can't get it in the auto store, try a marine store.

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.

Blue smoke when starting van & engine ticking very loudly in gears1 to 4


Blue smoke is caused from the engine burning oil along with the gas and oil. This indicates an INTERNAL oil leak. An external oil leak is one that makes spots on the driveway.
The ticking is probably from low oil or low oil pressure. Id have it checked pretty soon by a professional mechanic. It may be time to spend serious money.

2005 sorento 2.5 diesel.tick over fine.lift reves to 2000,engine goes lumpy,some white smoke then all hell breaks loose engine revs up to limit ,wont shut off with key and dissapears in thick white smoke....


Sorry to say this but you have a blown head gasket, this white smoke is diesel and water mixed, depends on how far you want to go now if you want to strip down or get a tablet that I mean a special tablet that you put in the radiator that does do an instant and effective repair, garages don't tell you this as it's for them only if you know what I mean, you get this tablet of the internet as garages not sell you one. please do not use the liquid sealers you can get to repair radiators.

Hope you get sorted with out to much cost.
Good Luck

Smokes when I start it, smokes ALOT when I start it, it is embarrassing...... after it has sat for aprox 3-4 hours and I go to start it there is so much smoke that I wait for people to clear the area. The...


I have a similar problem - though my timing is right exactly where it should be

I'm wondering if it has something to do with the build up of carbon in the manifold... the smoke has a blue gray hue as well and defiantely smells like diesel

But I'm also zen with the fact that there's always going to be smoke upon a cold start up... it's the price you pay for a diesel... now if I can just get it back up to 50mpg instead of the 44 I've been getting I'll be happier

Gray smoke & lost of power


The engine gray smoke is from excessive fuel burning to give the engine power. I am assuming the vehcle is an automatic transmission. Sound like I would have the transmission check for a lock up torque convetor. The transmission maybe taking off in second gear and starting out in a fail safe mode. I suggest taking to the dealer or tranmission shop.
