A bad head gasket , warped head , cracked block etc.
The antifreeze/water mixture is too weak for the conditions or you have engine oil or trans fluid mixing with it
You possibly have an internal water leak in the engine, ergo, a cracked block.
antifreeze....
there is no water mixed with the oil but have antifreeze coming out of the exhaust
No ! antifreeze is usually mixed 50/50 with preferably distilled water for your cooling system
Could be water or antifreeze getting into the oil
I'm not a mechanic / technician but I believe if antifreeze is getting into the engine oil it is because of a bad head gasket , or perhaps the head has warped
If you find traces of oil in the antifreeze it's an indication of broken engine gasket. You need to go consult with a professional.
no but antifreeze in oil will eat the bearings
No, oil is lighter than antifreeze.
You mean like water in motor oil? Easy to find out: just look at it. If it looks like mayonnaise, there's water in it.
NO! Take it to a mechanic immediately. Call AAA at once, if you are a member. Oil is not antifreeze and antifreeze is not oil!
