If water gets inside the gearbox, it will emulsify due to the "blending" caused by the gears and crankshaft. It turns the oil a milky color. The water can come from a bad oil seal on the water pump (if the bike is water cooled), or from condensation inside the gearbox. Sitting out in the rain, pressure washing or riding in creek beds can also be the water source. Find the water source and fix the seal or otherwise remedy the exposure. You will need to do an oil change. Please rate my answer. Thanks.

Ingersoll and 15T2 lub oil turning milky, why??

The milky appearance of the oil is due to moisture (water) getting into the oil. I recommend that you drain and change the oil immediately. atmospheric variations (particularly high humidity) will cause this. There are two reasons. First, when the compressor is running, air coming through the air intake will have water particles in it. That moisture in the air slips past the piston rings and accumulates in the crank case. There's no stopping that, but a clean air filter will help. Secondly, while the compressor is running, it tends to heat up. Any moisture that has entered the crank case will vaporize due to the increased heat of operation. When the compressor is shut down, the moisture vapor will condense on the inside walls of the crank case and form droplets which will run down into the crank case oil. When the compressor is started again, the oil agitators at the bottom of the pushrod caps will agitate the oil, thusly mixing the condensed water with the oil causing the milky appearance. Best to check the oil at each start-up, and change it when it gets milky.

Car stalled had no pick up milky leak

check your oil, if it is milky looking it is likely 1 of 2 things, head gasket (most likely) or a cracked head/block

in either case oil could also be in the radiator but its usually water in the oil, i would check both

look for coolant in your oil ,the oil will look ''milky'' if there is coolant mixed in it. if you have milky oil then you have a blown head gasket. if thats not the case then we have to look elsewhere. hope this helps
