I bought the truck with 111,000 miles, all freeway miles. It has 223,000 now and I replaced the plugs at 150,000. Bosch plugs suck, in a chevy anyway lol
Look at the threads!!!! Thats the threads from inside the head. Gezz I will try a helicoil repair, if not I get to replace the heads. Damn I can't win for losing right now........
