Any time your engine oil is milky it means you have water in it It's got water in it from somewhere. Probably a blown headgasket. Hopefully not a cracked or warpped head.
Blown head gasket. That milky look is coolant mixed with the oil. STOP driving this vehicle until you have this repaired or you will ruin this engine.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
A cracked radiator will NOT put water in the engine and make the oil milky. A bad head gasket WILL put water in the engine and make the oil look milky. That does not neccessarily mean you have a bad engine. Have someone fix or replace the radiator and replace the head gasket. It could be a good engine for a long time yet
The head gasket is gone and water or coolant has mixed with the engine oil. Replacing the head gasket is no big deal.
this is usually engine coolant leaking in
It should look like oil. If it has been in the engine for some time it may have an almost black appearance to it due to the dirt and sludge it has in it. If your oil looks milky you could have a problem with a blown head gasket or cracked block.
First remove your engine's oil dipstick and look for discolored oil(sometimes milky colored) or if engine is hot small bubbles. Also look for excessive water from tailpipeand/or white smoke.
Check the oil on your dipstick. If the engine is warm, the oil level will be high and look milky or light brownish. If the engine is cold, the oil level will be high and you will be able to see water droplets on the end of the dipstick. If the oil is mixed with the water it will be grey. If not the water will be at the bottom.
drain oil,raditor.
Just look at your engine oil and you can tell, if it looks milky there is water getting into the oil and that's the sign of a blown intake gasket or head gasket.

A crack in your oil pump shouldn't make the fluid milky. Water mixed with oil will look milky so I suspect you have a cracked block or blown head gasket.
