hi ali, nice to hear from you so soon, you need to check your coolant for any oil in water, if you find some then its possible your head gasket going, if none showing, then you have a leak somewhere, so check your gearbox seal, rocker box gasket, change them if leaks found. or, take car for a run park up as normal and put cardboard or paper under car to see if any oil dropping down.

hope it helps, October 2010
