So in my rather pathetic attempt at trying to drop the engine (wanting to only do this by 1" or so to remove the water joint) I managed to break off one of the two pegs on the Lower Adjusting Bolt the Upper one came out fine (well not all the way but enough to free the spacer).

My guess it is suffering from corrosion, I tried wedging a screwdriver end in the gap to close up the gap when trying to undo it but to no avail. I guess the only way to get this out is to use a large extractor (tap and die) or is there anything else, any ideas suggestions would be most welcome. Just to top it off I can not get the castle nut to thread back on 

If I can not remove this is there likely to be some kind of vibration, chatter?
