Head stud removal

[Denis Sweeney]

Having now removed all the valves, tappets and core plugs, have cleaned to top head to check for any cracks, unfortunately the block is cracked between the central stud and the waterway immediately behind it. The crack then continues on the other side of the waterway and travels up between valves 4&5 where it reaches beyond the mid point of the valves. The crack was not visible until the block face was cleaned and wire brushed, once clean it clearly visible to the naked eye without any dye pen. I’m gussying this is pretty terminal, but if it wasn’t I’m not sure I would ever use it.
