Most likely cause is " you have a blown head gasket" or " a crack cylinder head" either way you look @ it You have serious problem. This is an expensive job that can run you anywhere from $1000 to $2000 depends on the problem and who do the job.
A bad head gasket is the most common cause of antifreeze mixing in the oil. The antifreeze will dilute the oil and it will eventually cause your engine to seize up.
Bottom of the engine
When antifreeze is poured into your oil, it weakens your oil cause it to break down prematurely and can cause your engine to fail by spinning an engine bearing and even smoke. This is also a sign of a blown head gasket.
Head gasket could be bad
Blown headgasket or an idiot pouring oil in the wrong hole.
cracked head or bad gasket
You can fix oil that is getting mixed with antifreeze in a Ford Econoline 250 of the year '98 by replacing the head gasket in the vehicle. A blown head gasket will cause the antifreeze and oil to mix.
If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.
