    My exhaust manifold gasket needs to be changed on the passenger side. I went to pull off the exhaust manifold and found that the reason it is leaking exhaust so bad (hot exhaust is just being trapped under the hood and everything is hot to the touch) is because one of the exhaust manifold bolts is broken off in the head. What is the easiest way to fix this? Or would it just be better to pay someone to fix it for me and if so about how much does that cost? Thanks

    Is there any of the stud still sticking out from the head, or is it flush or inside? If there's none sticking out then you'll need to drill it & use an "easy out" Be sure & spray the heck out of it with WD-40 or some other penetrating lube a few times before trying to remove it. The reason these snap off is because of the length of the exh manifold allows it to warp outward with all the heating & cooling cycles & pop the stud(s). You will need to have the manifold machined back to true. I have no idea how much this would cost at a shop because labor rates vary so much across the country.
