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.
Good Luck

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.

SOURCE: water is mixed with oil.

I think you have a bad intake gasket. These engines,(vortec v8 and v6 ) are well known for this problem

SOURCE: audi a4 mixing water and oil together hissing,grey/brown foam

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.

What can cause a heavily mixing oil and water in the engine but no oil found in the radiator


There is oil already in the engine oil pan and lubrication system and apart from some condensation there should be no water. The only place water can come from in any quantity is from the cooling system and although cracks and leaky water heated inlet manifolds and gaskets can be the cause the most common source of coolant ingress is the cylinder head gasket.

A failing head gasket doesn't very often mean there will be oil in the coolant.

Hi, i have automatic passat 1999 model and recently water happens to get into the gear box and it control board, i experiences a boom sound anytime the gear is changed, the oil has been changed by the...


If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

Antifreeze looks almost black in color is thisnormal.


No this is not normal, Sounds like you may be getting a little oil mixed with the water flow. I would have this checked out because you may have a crack within the engine allowing oil to mix with your coolant system.
