itsmemtn Posted February 6, 2014 Share Posted February 6, 2014 I know ive seen this before on here but for some reason cant seem to find it. I have two broken exhaust manifold studs on the drivers side. Ive tried to get a drill bit/easy out in there and drill them out but I am unable to get it lined up correctly. The way i see it the only other way to remove and replace them is to remove the head. I already have 6 new studs and a complete head gasket kit. Was wondering if yall have any tips or Info on removeing the head and if any special tools are needed. thanks in advance Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 6, 2014 Share Posted February 6, 2014 If you know someone who has a MIG welder or can rent one it is possible to weld a large nut on the remaining steel stud in the head and remove it with a wrench. There's no worry about welding anything to the head itself since it's made of aluminum not steel. I hear it's way easier to fix it that way than to remove the head!!

itsmemtn Posted February 6, 2014 Author Share Posted February 6, 2014 only bad thing about doing that is there is no part of the studs sticking out of the head Link to comment Share on other sites More sharing options...
k9sar Posted February 6, 2014 Share Posted February 6, 2014 placing the nut against the head and throwing a weld insode the nut, to the stud is what would be needed. Don't worry about the aluminum head getting screwed up at the threads by the heat, as you ease the stud out (slowly, carefully and with penetrating oil), it will rethread it if needed. You may lose a thread or two but since the stud goes in ove a half inch, there's plenty to grab. Link to comment Share on other sites More sharing options...

5523Pathfinder Posted February 22, 2014 Share Posted February 22, 2014 If you have a decent amount of drill bits, I used to use a larger drill bit to drill the face of the broken stud and knock a small amount of of the aluminum out of the way. This deburs the area and centers for a smaller drill bit. Drill, tap and remove. Link to comment Share on other sites More sharing options...
Precise1 Posted February 22, 2014 Share Posted February 22, 2014 ^ Always apply penetrating oil, use left hand drills (CCW, sometimes they will walk the bolt out themselves) and good removers, I prefer the square design for the smaller bolts. An automatic centerpunch can help a lot to make a start point in the center as well... B Link to comment Share on other sites More sharing options...
