Thanks MB Medic. I tried some rust dissolver and a propane torch today but it won't budge. I don't have any edge to grab either. I guess the years of corrosion have really seized it. I may have to remove the camshaft. Can this be done without removing the timing chain completely? I would rather not get myself into deeper trouble. Anyone else got any ideas?
