So I went to start my truck today and the back spark plug on the drivers side blew out. I just bought the truck and it has newer plugs and coil packs so I'm assuming the person who installed those cross threaded the hole and made it weak.


My question is what the heck do I do from here? I don't really want to tear the head off of the truck or tear the truck all apart. Is there a product out there that is designed to fix this while the head is still on the truck?

Any help will be greatly appreciated, thanks.
