Need help in diagnosing a motor problem in my 03 a4 quattro 1.8 turbo.
One afternoon while checking the oil in my wife's 03 a4 Quattro 1.8 turbo I noticed that the water reseviour was full of dark fluid appearing to be engine oil. When I checked the oil there was barely any on the dip stick. I had high hopes that after allowing our daughter to use the car that she might have added oil to the wrong place. But unfornately there appears to be bigger problems at hand. Normally the car doesn't use any oil and as of now it still runs great, but after adding some oil to the engine and running it for a few minutes there is water in the engine oil as well. I done a compression test and all cylinders still have over a 170psi. Like I said the car still runs great but this oil exchange is not right. I'm wondering if someone else has maybe had the same problems and could give me some advice in witch direction I should go in diagnosing the problem. I would hate to pull the head and that not be the problem.
