My coolant looks like chocolate milk?

Sound like it might have some oil contamination, which means a blown head gasket.

yup, probably a head gasket then. You should try not to drive it if you can get away with it and take it to a mechanic to have it pressure tested.

def head gasket on that car. I have a 325es sitting in my drive right now that I will be doing this on once it warms a little. Easy job on the 318 though, take you 6 hours or so if you know what you are doing. Get the head decked while it is off

The break in the gasket could be around one of the oil/coolant channels and not cylinders so you aren't getting coolant in there. An engine will run with a blown head gasket depending on where it is, just not for very long.

Headgasket's gone. Replace rod bearings as well, depending on how bad it is, otherwise you may get the knock soon.

Chocolate milk means (as others have pointed out) that oil is entering your coolant, most likely through a leak in the head gasket. There is also the possibility that coolant has now entered your oil supply as well (check your oil fill cap and dipstick for the same foamy mixture). You'll need a new head gasket which on a 318i isn't too bad but if you have the time & patience to do this:

to your engine. If not then it may cost you around $1k depending on how much labor costs where you live.

Does it taste like chocolate milk?

Quickly sell it. You'll get a buyer that doesn't look at the coolant and you can sell it for a fair market price. Saves you a grand in repairs, and you can go buy a 318iS.

i dipped my fingers in the coolant and rubbed them together. doesent feel oily at all. Also there is no coolant under the valve cover, oil looks normal. is it possible there is something else wrong with the coolant?
