engine is burning oil could be valve seals or piston rings
there is no water mixed with the oil but have antifreeze coming out of the exhaust
Maybe a blown head gasket
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
your not getting oil to the engine or its running low
Your engine is most likely overfilled with oil. Check your oil and make sure it isn't overfilled. However a little oil coming out the exhaust isn't gonna hurt anything, your just gonna waste a heak of a lot of oil
high probability you have a damaged engine
if you have blue smoke coming into the exhaust that means your piston rings are bad and are letting oil into your combustion chamber and then causing the oil to be burned with your air fuel mixture and that's why your exhaust is blue from having that burnt oil dumped out of the exhaust valve and out the exhaust
There is usually a noticeable aroma of anti-freeze coming from the exhaust, or bubbling in the radiator with the engine running. Also, there is sometimes oil in the radiator or anti-freeze in the oil. A compression test usually tells the story.
You have too much oil in your gas, that's why oil and gas is coming out your exhaust.
leaking past the rings
You may have very worn piston rings, letting oil through. Take it for a'compression test'/
cause so times if you crash in a rock or a tree . then the oil comes out of the pipe
