A quick albeit unrelated query, on the rocker cover of my 1997 P38 there is a hole with a off set edge into which a braided pipe has been pushed, this goes into the turbo intake which spans the top of the engine cover. However other rocker covers I have seen, seem to have an aluminium pipe sitting at 90degrees into which the braided pipe seems to be attached. The braided pipe seems to be attached to a round jobby which I think I some sort of breather for the turbo. Sorry for the rambling post guys
