In the interests of accuracy I`m 99.99% sure that the foil (an attempt to stop it freezing I`m guessing) was placed there by the guy I bought it from - NOT by any of the mechanics who have subsequently worked on it
I should also add that the guy who first replaced the gaskets added a "blow off valve" type device that didnt work (obviously), most likely because it was installed at the rear of the engine with the output pointed downwards meaning that water (condensate) could collect there and freeze (Doh!)
I only discovered on friday as to how he had modified a vacuum line into the CCV too - he did tell me when I last picked it up that he had undertaken this modification and it should cure the problem
I dont fully understand what was going on but from memory I think there was a vacuum pipe blocked off and another drain pipe had been rerouted to somewhere it wasnt designed to go - my current mechanic said this was a bad idea as it created too much vacuum and was unnecessary so he intends to put it back to stock
