I found out that oil and water mix in my engine.what could be the cause
Could be a blown head gasket, intake gasket....whatever it is, it isn't a simple fix...
You'll need to take it to a BMW shop or reputable shop and have a pressure test done.

SOURCE: Oil engine oil mix with water
sounds like you have a problem with the head or head gasket.Pulled out the spark plugs and see if you have any showing signs of leakage from head/gasket.

SOURCE: water/oil mixing in 22r engine
yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.

That is not true oil and water being mixed can come from many different places. Such as a bad radiator which would cause transmission oil to mix with the water also alot of audi's have a water cooled oil cooler which are a very common cause of oil being mixed with with water. These type of oil coolers are located under you oil filter. They have water lines hooked to them which cools the oil and when they go bad the water and oil will mix. So dont be convinced that its your head gaskets it could be but not as likely. You can pressure test your oil cooler to see if this is the problem just romove it an plug one off the inlet or with rubber plug which can be purchased at you local hardware store (I found mine at ace hardware in there specialty drawers where they have all there bolts) then attach a air hose to the other outlet pressureize the system and place it in a bucket of water. this should tell you if the oil cooler is bad but be careful not to ove3r pressureize the cooler this could damage it and caust it to leak. 15 to 30 psi should be plenty.

SOURCE: oil mixed with water in coolant
have you checked your engine oil if it looks the same?? If your engine oil is mixed/milky colored, then its your head gasket!!hopefully this helps!!
