This is most likely a severe failure somewhere internally in the engine that resulted in coolant in the oil. different root causes are probable. oil should be checked regulary (do a oil sampling) after it has been replaced.
oil getting by the rings causes white smoke and oil dripping out of the tailpipe.
White smoke normally means you are burning oil.
blue smoke is oil. white smoke is water. black smoke is unburnt fuel
the engine is burning oil. blue smoke oil white smoke antifreeze black smoke excess fuel
depends on the color of smoke... white=water black=fuel blue=oil
Two cycle engines have an oil gas mixture and if there is too mush oil to gas you will see it burn as white or gray smoke That or your valves are bad.
Piston rings or Rich oil .
Head gasket
Any vehical which emits white smoke out the back means there is a problem with the engine burning oil. Check the tail pipe to see if it is dripping a mixture of water and oil.
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.
It depends on what color the smoke is. If it is white smoke that usually mean coolant is in the oil and that can be a result of a blown head gasket. If it is a greyish bluish color then it is oil burning. if it is black then you are burning gas.
piston rings going bad oil leaking around to top of piston so when you start the oil will burn white
