Well I was retightening the fuel rail bolts on my rev hard mani today and guess what...2 of 3 stripped completly out...I could see if I were doing it by guesstimation, but I was using a torque wrench, a nice almost new craftsmen, so I am positive that it was not that. Does anyone now off hand what helicoil to use, or how to repair it...I really appreciate your time.
