Just wanted peoples advice on what to do next. My no 2 spark plug decided to pop out the head the other day as i was driving down the road, it looks like it wasn't seated in correctly and with all that pressure it just gave up. Now the spark plug threads in the head are stripped and it just wont go back in.. Can i just buy a thread insert and wack that in? Or re-tap the threads ect Any help will be highly appreciated
