hey guys, i recently blew my turbo, so im reverting the car back to stock and in doing so, i rethreaded the thread for the oil sensor. so i rethreaded a new thread, and as you know the oil sensor screws into a small piece of the block that sticks out, so anyways i put a bolt in and then CRACK, the top part of thread breaks off completely. what am i to do now?? can i weld this hole shut or jb weld it??

 

anyone?

 

weld and re-tap or just leave it welded shut
