  • This is a very broad question. There are so many things it could be, from a bad gasket to a bad head gasket allowing coolant into to the exhaust. The two things may or may not be related. Can you add more details about the problem? – CharlieRB Aug 23 '16 at 13:02
  • White smoke usually indicates a coolant leak into a cylinder. This is usually caused by a blown head gasket, but there are usually other ways as well. Definitely not a good thing. – Pᴀᴜʟsᴛᴇʀ2 Aug 23 '16 at 15:32
  • Muffler is clogged? – Moab Aug 26 '16 at 21:57
