Hello and Welcome -

My name is ***** *****

The Engine light will be coming on as a consequence of the problem casuing the white smoke.

White smoke occurs when raw diesel comes through the exhaust completely intact and un-burned. It will usually sting your eyes when you get this -

Common causes are as follows:

  • 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)

Water entering combustion spaces will also create white smoke. Faulty head gaskets and cracked cylinder heads or blocks are a common cause of water entry, and are often to blame.

Check your coolant levels - with your outlined symptoms I would first suspect coolant getting into the engine ( head gasket leak ) as the cause -

Let me know how you go..and / or let me know if you need anything further on this..

~>>>~~~ Meantime - Please do click on the "Exc / Ok rating" for me at this time.. Thank you in advance for that . ..

Note that you can get back to me anytime at all after doing the rating - it doesn't close you out -

- Best Rgds, MIKE.
