Engine oil in coolant?

2001 Mitsubishi Montero not the sports one the problems with this vehicle

Overheating, radiator boiling (no thermostat took it off when i flush the cooling system ) oil in coolant and alot of it looks like milk shake, i have flushed the cooling system many times and the milky substance always comes back.

I have already replaced the upper and lower intake!manifold gaskets dont know!if they will help but could it be a crack head because there is no white smoke coming from the tail pipe.

The car has a external oil cooler the only thing attached to the radiator is a transmission cooler. Radiator was replaced a few months ago. Im thinking its a crack block near the oil pump maybe any info is appreciated

    The reason can looks like it's a head gasket failure. You have to get it pressure tested to confirm. You can quickly check the oil in the engine for water which would appear milky. If all is fine can be the external oil cooler mixing with oil. Do the simple checks to verify. A pressure test or a carbon test in the coolant will reveal the result.
