wondering if a flood out could cause milky oil or if its a head gasket problemb eaither way i can fix it i just hate to pull the heads if i dont need to.
I would first drain the oil and put a new filter an oil in the engine. Then see if the problem continues. Has the car been sitting for long periods of time? Does the radiator keep getting low for no apparent reason? How much milkiness is in there? Do you drive it for an amount of time for it to get to operating temperature and stay there, or lots of short trips? Try the oil change first, assuming you haven't already, and see how it goes. -Corbin
I agree with Corbin, there is also another factor I have run into. Sometimes when sitting overnight or even longer, a instance of high humidity or condensation will get on the dipstick and turn it milky. The oil change will rule that out if the problem shows up in the filter and drain pan.
