This morning I removed the valve cover again and found that the rocker arm I put the helicoil in was loose. The bolt was not loose and was still torgued properly (168 plus 30 degrees) the rocker pedestal was firmly in place but I could turn the rocker arm clockwise and counter clocwise about 20 degrees. When I did that the pushrod had lots of play. I am hoping that the rockerarm needs to be replaced and that the clicking sound will be gone. Any thoughts?

Do you mean that the helicoil itself was losse? Could this be because the aluminum casting expands more than the steel helicoil?
