I've recently had the cylinder head off my 1976 1098 Clubman to replace head gasket and studs.
I have come to adjusting the valve clearances and have found nearly all tappet adjusting screws to be heavily seized and have snapped the screw head whilst trying the undo.
Obviously I now need to replace those broken and any more that break when adjusting.
Does anyone have any bright ideas to help to remove/loosen the remaining screws without breaking them?
To replace these adjusting screws, I assume I need to remove the rocker shaft as the ball won't come through. What will happen where I have torqued the head down? Will I need to replace head gasket/studs?
Any help or ideas would be much appreciated!
