You have a blown head gasket ! The milky looking oil is coolant getting in there ! Mite smell like gas because some of that is getting in there also ! It over heated ,warped a cylinder head ! Milky oil How to tell if your oil is milky
So sorry to hear of this Problem, But You have either A head Gasket that has Acquired a Crack or A crack in the Engine Block somewhere between the Cylinders and an Oil port. this is what will cause Milky Oil in the Coolant reservoir/overflow tank, if the color is More Brown then it is Definitely engine Oil if it is Reddish then it is a trans coolant leak But since You say you replaced the Radiator then My money goes to and Engine Problem, You nee to See a Professional Mechanic shop to have the System Pressure Checked, And The Oil Dipstick checked, if You have Milky foam on that stick then You will have narrowed down the Problem
Few possible causes... You could have a leak in pipes or cooling radiator, you could have a leak in your heater matrix, has engine overheated? You could have a blown head gasket, check for leaks & remove oil cap and look for creamy milk colour sludge, if you see milky colour sludge under your oil cap then your head gasket needs replacing
You havw a serious problem with water getting into the oil. Most likely it is leaking from the head gasket. You mentioned that the head gasket was replaced 6 months ago. Did the cylinder head get re-tighten after several hundred kms. If not this should have been done to avoid this problem.
Have your Cooling System pressure checked. Also check your oil and anti-freeze. If the oil is milky or the anti-freeze is oily you have a blown head gasket. Watch for white smoke (Steam) coming out of the tail pipe after it is warmed up. If you have white coming out that is coolant, black is fuel and blue is oil. After the pressure test if there are no leaks detected in the hoses then get a compression test to see which cylinder is leaking.
This is NOT a good thing...Better check you engine oil. When engine coolant disappears without any signs of it leaking on the ground, it is usually because it is leaking into the crankcase via a blown head gasket, blown intake manifold gasket, or cracked cylinder head. If your engine oil looks milky, like a chocolate milk shake, it is time for major engine repair or replacement.
well it sounds like you have a major problems here . If your coolant level is dropping and the oil level is high it sounds like you have a head gasket leaking coolant into your oil system . Is the oil a milky color . if so i would look at a head gasket problem . Also if the oil does look milky it may have gumed up the oil level sensor so it is not working right
