How fix the problem of white smoke from hyundai accent


White smoke is usually indicative of unburied fuel. Have injectors checked and cleaned. Easiest solution, run some injector cleaner with half a tank of gas, then when that is gone put in a half tank of high grade fuel and run that. If you still have the problem then it may be time for new injectors.

Audi 2.5tdi white smoke on exhaust low revs


Hi
White smoke is usually a good sign of un-burnt diesel so reading your post and all the things you have already changed ie the glow plugs I would have the injectors tested to make sure they are atomising properly as it sounds to me like when your car isn't under load ie at low revs you have a cylinder that isn't firing correctly
Hope this helps Nick

Excessive exhaust smoke on the first start of the day


Sounds like the valve guides are leaking oil into the cylinders, or there is a coolant leak somewhere. Usually white smoke is coolant but could be oil.
Are you adding either fluid often ?

Ford Focus 2005 - cold start backfire - runs great after 5 mins, when hot


White Smoke out the exhaust, is usually a sign
of coolant & most likely the start of a bad head gasket

At this point your use of the car should be curtailed,
to prevent any further damage

You should not use the car at all, until all issues are
diagnosed & resolved

Plan on using other means of transportation

Misses and lots of white smoke on start up when sitting for 10-12 hours. New glow plugs and injectors. 141000kms. Non return fuel valve fitted between filter assembly and injector pump. Cheers stu.


first question is it smoke or steam ? if if ligers in the air behind you as you drive with little dissipation or if its steam it will dissapear more quickly . either way , head gasket is first . once saw a car do that excessive engine oil put in by owner . giant flumes of white smoke . if you ever want a true smoke scren to get away then adding about 2 to 4 quarts of oil extra . man it is something to see
