Hi I want to remove a damage stud .It is locate a oil pipe to 2nd turbo.so can I use a electric weld machine weld other stud then using a plier(It can have more torque can hold the stud because too little room that I can't hold the stud when I using plier).I also can't use a stud remover .So any fire or cable shot If i use the machine?or any suggest?

 

try a plumbers pipe wrench, they work great on the exhaust manifold studs. you might need a smaller one for the oil line stud though
