Thanks for that though it does seem to be more than a thin film where is the turbo located and no I haven't checked the pipe I presume that's the black one to the right of the picture. Not to good with cars does it show but also don't want to take it to a garage and be had over did think it was turbo seals as there is a slight whistle everytime I change gear either way I best get it to the garage me thinks thanks again. Could I be looking at a big bill??
