Any help appreciated
 

After attending the Mcrae weekender a couple of the lads following behind me commented that my car smoked a little but surprisingly not when being driven hard but one one occasion when going down hill so I guess off boost.When we arrived home after some 600 miles in a weekend I checked the oil which was between the marks on the dip stick and also took the radiator cap off and found an oily emulsion on the neck of the radiator.My first thoughts were HG as the cars a 2006 WRX Hawk but after speaking to a local mechanic he seems to think the turbo could be the problem.As I am not a mechanic I cant see how the turbo might allow oil into the coolant system so Im at a loss to know which way to start to deal with the problem.Just to add the car never missed a beat all that weekend never over heated in fact if the guys behind me had not told me of the problem I would have never known.
Thanks in anticipation for any input.
