engine smokey when starts?

Question

it clears after when engines warm it's a diesal engine.

does anybody know whats wrong with it?

how much it would cost to fix?

Thanks Guys I don't know which is the best answer not knowing much about cars. so I will let it go to vote

Answer 1

theres probably nothing wrong as most diesels do it. try to keep it serviced regulary

Answer 2

If its white smoke then it is unburnt diesel and can be attributed to poor compression or valve timing.Mostly it is not restricted to cold starts.
Blue smoke when cold started is usually excess oil that leak from sump to cylinder when the piston is contracted by cold temperature.As the engine warms,the piston expands to close the gap,excess oil cannot pass into the mix and the smoking ceases.
The engine is worn,unless it is a new car ,it is probably not economically viable to make a repair on this engine.You would run it as long as possible before replacing.

Answer 3

this is just black smoke caused by loads of carbon build up you will also find when you accelarate in a diesel it does the same thing most diesel cars do it these days nothing to worry about, always good to flush the fuel system though try wicks injector and valve cleaner 10x better than redex pop some in a full tank of diesel and drive it up the motorway like you have stole it, sounds harsh but it flushes everything. good luck

Answer 4

Probably leaking injectors alowing fuel to drip into the cylinders and coating the pistons and cylinder walls.
Then, when it starts, all the fuel that's been sitting there takes a little bit to burn off.

Check you engine oil level to see if it's over full, and smell it to see if it smells like diesel.

You may need to replace your injectors.
Sorry, I don't know how much that would cost though.

Answer 5

If it's blue smoke, it's oil that has probably run down past worn valve seals. If it clears well & you aren't using an substantial amount of oil, it's nothing to worry about.

If it's black smoke, that's just excess diesel & most do it to a certain extent, though your car could probably benefit from some injector cleaner.

Answer 6

probably valve stem seals worn and a small amount of oil is passing the seal on to the piston but as the valve warms with the engine heat it makes a better seal and stops smokingThis is assuming you are not using large amounts of oil

Answer 7

what colour smoke? White- I hope not thats water getting in the engine. black - ok well it probably needs an oil change.
speaking of oil check the level if its too much it needs draining and changing

Answer 8

without seeing it i cant realy say for sure, try a fuel addativev (red ex) or the like if its not serious that will fix it.

Answer 9

a think every thing has been covered by the above contribute-rs, some good answers.

Answer 10

dont give it 40 fags a day tell it to give up
