if i was to replace the head what sort of costs would i be looking at to get a garage to do it? also what other parts/seals would i need? ive seen a head for sale on ebay http://www.ebay.co.uk/itm/321173771905?s...1423.l2649
I think you need to take the head off and look at the threads on cylinder 3. Its obviously not right. Regarding the tube going down, I should hope it does go down past the threads as that's the way to the cylinder. When you were hovering I guess number 3 cylinders piston was lower down than number 4s.
