Spent all day getting ready for the wet stuff on monday when I noticed a hose that runs round the back of the engine and goes through a clip that is connected to the cyl head, i was concerned that the clip had rusted quite badly and could cause the pipe to leak, in iyself not a problem, i was just about to undo the rusty bolt holding the clip when I noticed that the rust was not limited to the rear of the head but extended all the way round the side just above the sparks. I then entered the "it aint broke dont fix it mode"<br />but have come away rather worried about how long the head is going to last and how much it would cost to replace........is this a common problem??any help/advice appreciaited.
