Made a start removing the intercooler and pipes and whilst removing the lower pipe that was working on earlier this week I found the joint that was leaking oil was really loose, I must of missed it checking them, anyway I removed the pipes and intercooler, filled the intercooler with petrol and sealed up to be left soaking over night and cleaned the pipes it with brake cleaner, the inlet manifold has some oil in it but I don't have a gasket but will get one from the Peterborough show next weekend along with a fuel filter and as I had a 25ltr drum of oil I decided to drop the oil and refilled to between the High and Low marks so tomorrow I will clean the intercooler out and refit everything and see how it goes
