Hi I have a 2003 SE Passat, 1.9 td (red) I . 78000 miles.

Ive recently had to top up the oil I assumed I had a leak as its needed topping up slightly a couple of times over the last week or so.
Today I had a warning -STOP- check coolant level.

I stopped of course, opened the coolant reservior and found it full to the brim with thick black oil. Not the chocolate mousse type mess you find with a head gasket but a real thick custardy black used engine oil.
There is no contamination with water in the engine oil, but as I say the water has turned to oil lol. Power is deffo down but more noticable in lower gears. (stopped driving as soon as prob was noticed btw)

My first thought was Head gasket but now Im not so sure because of the sheer huge amount of oil in the coolant and the fact that it hasnt been whipped up into a froth and no water in oil.

Now Im thinking its a problem with the oil cooler or maybe the turbo. (prays not)

Has anyone else had the same prob ? any help/advice gratefully accepted!

Thanks
