My son had his truck recently tune up. The dealer seemed to have left a spark plug loose. It now has came out damaging the last 2 threads in the head. I know the thread size is 14mm but I cannot find the pitch. They told him at the dealer ship the torque on the plugs is only 15 ftlbs. is that right. I would like an answer asap as he can not drive the truck. Thank you
