Now I dont know how to get to that valve cause the aluminum screw got badly damaged as it held the position and the screwdriver messed it up to the point it cant be moved a bit by a screwdriver. Any suggestion on how to get trhough this? And what to do when the spring is broken? Do they still sell them and what part number is it? Maybe I need to get another valvebody . Are they interchangeble with v8 valvebodies? (except v8 w124 I know its 1gs)

Sorry for my engish Im from Slovakia

thanks
