I'm about to tackle my broken exhaust studs. I need to buy some cobalt left hand bits. For those who have done this already, what sizes will I need? I know I should buy a few of each and I don't want to buy a whole set since I know I won't use most of them. Also, what brands are good? I've searched and found some made by Hanson, Neiki, USA Pro, Northern Tool, etc.

 

Go to Harbor Freight they got some good ones...should be cheap enough 4 ya dude.

 

mine sucked. idk how you could do it with the motor in. when i pulled my motor for the clutch i put all new in then

 

I know it's going to suck, but it's the front manifold and I know it's been done before by many with the engine in. I'll buy some from Harbor Freight. Hoping to drill on center so I don't have to waste any more money on helicoils.

 

I had my old broken studs removed by having a bolt welded on to them and then simply removed with a ratchet and socket
