Milky oil means that there is water in the oil. This can come from several sources. There can be a failure of the head gasket, a crack in the block, or a crack in the head. The only way to be sure is to take the head(s) off and examine the head and gasket!!
If the car was sitting for a long time, and you find milky oil, you could change the oil, and drive the car for a bit. If the oil does not turn milky again, it was just condensation in the engine (not something to worry about). This would likely only be the case if the car sat for over a month without being run!

At the very least, you need a head gasket. Hope like heck that you don't have a crack in the head itself! Milky oil means that water has gotten into it from somewhere.

Coolant mixed with oil -could be from a number of sources. Usually head gasket or a cracked casting.

Yes,most often a milky oil means water is sipping through,it also could mean crack head or warped head,problem needs to be fixed immediately or cylinder walls,pistons,bearings,crankshaft,rocker arms and anything that has to be lubricated will corrode and seize

Not always.Is the oil milky on the stick? If it is just on the filler cap and you do a lot of stop start around town,this can also cause milky oil.
