1.7 pedestal roller install ?

I bought some crane 1.7 rockers and followed install instructions.But I seem to hear some ticking.I can't tell if the injectors or rockers.The noise isn't loud,but wondering if some noise is normal with rollers.Instructions said 1/4 to1 turn before hitting tourqe spec(18 tt 20lb).Tried to get 1/2 turn before hitting spec.Which I did except for 1,just got 1/4turnon that one.
