What a bugger I was driving along this morning started loosing power suddenly got worse it has broke the rocker shaft, the front bolt had pulled out took the shaft off and a helicoil was still on the front bolt, obviously the coil had pulled out dont know why. The question is how to repair it can you helicoil it again or drill a larger hole and helicoil a helicoil, are the liquid metals on the market as hard as they say they are, the other trouble is I think the first bolt is also the oil feed also, I dont want to get another head, gaskets, and all that carry on. Any of the experts have an answer to my dilema, any help would be appreciated.
