When I changed the valve cover gasket and I think that one of the studs may be stripped. While tighteneing the lower, left cover bolt all the way in the back, the hardest to get to, I think the force required during tightening got easier. I was using a 1/4" drive and could hardly get a grip on the rachet, I do not know how I did it. My questions are - Can a new stud be purchased? Has anyone ever changed one? They do not appear to be too difficult to change. I appreciate all help..
