Check oil by draining. Trans tank on radiator bottom may be oily slick you see if oil pan drained clean. Then trans is probably contaminated with antifreeze and that's what is mixing.

Crack in head passages could link oil and water, if you verify antifreeze and oil mixed in oil pan.

Engine problems?


Head gasket. White smoke is always a sign of water getting into engine cylinders. And if not the gasket there could be a crack in cylinder wall allowing coolant into chamber! Water does not burn!

Engine will run for sh**.

Vw bora v5 mixing oil with water at the expansion tank. what is the fault?


Most likely a cracked head. They are often difficult to see with the by eye and can be in places you cannot see. One thing though, do any of the head bolts extend into the water jacket? If so, when you install them you need to use a manufacturers recommended thread sealer on the bolts or water from the water jacket will wick up through the head bolt threads into the head itself.

Engine oil mixing into coolant


The only place, oil and water share a gasket is the cylinder head gasket, oil and water galleries run through the engine block and head via the head gasket. The cylinder pressure will be OK, it's the oil pressure that's putting the oil in the coolant, the gasket has gone between the water and oil galleries or there is an internal crack (unlikely). A coolant pressure test should show it up.

I am finding oil in the radiator.


This almost always means a bad head gasket or a cracked head/block, unless you are a mechanic this isn't something you are going to be able to fix yourself and is likely more costly to repair than the car is worth.

I'm losing water out of my radiator but i can't see that it is leaking any where. I'm not sure where the water pump is. For some reason, the water seems to leak out of the over flow when it is hot.


check your radiator cap condition if its ok then your engine must be having a cylinder head gasket problem, normally when engine overheats the cylinder head gasket gets fried-up and the water goes off to the exhaust along with the exhaust gas thats why u dont see any trace of leakage on the floor/ check your engine oil as well if oil and water mix together to conclude the theory.

Suddenly started smoking white smoke and seems to be losing power


White smoke is coolant being burnt. That with your lose of power would suggest a bad head gasket. A compression test could confirm it. Hope this helps.

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.
