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.

Mercedes c200 wont start lots of new parts white smoke comes out but says low pressure diesel rail replaced injector rail and two injector switches still wont start


WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include
  • Faulty or damaged injectors
  • Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway).
  • Low cylinder compression (eg caused by leaking or broken valves, piston ring sticking, cylinder and/or ring wear, or cylinder glaze)

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

Toyota Caldina 1999, too smoke from exhaust


if it is diesel and you have black smoke you need fuel injectors either serviced or replaced also you must check the engine valves clearance. If your smoke is blue white smelling unburned fuel renew injectors.If it is blue white smelling oil and diesel then you will have piston rings and valve steam seals.

2005 transit loud turbo,no power especially on inclines,puffing black smoke from exhaust


The black smoke is blow-by you need a ring job. Oil is getting by the top ring of your pistons in one or more cylinders. Loss of power under a load is also indicative of this.

White smoke


these engines are pron to injector failure !!! white smoke means dumping fuel ! black smoke means lack of air ! blue means burning oil! its not an easy task! by all means not cheap! ull need 7 injectors and one #8 injector call a ford dealer to see the price ! but i would also call an international aka navistar dealer! there sometimes cheaper
