You should be able to see a bit of light on one side of the base under the straight edge. If so the cam lobe is good that the particular lifter lived with. It the lifter is flat or is worn concave you also need cams.

Thanks for this additional information, I will check this.
As the 'ticking' is not continuous I hope it is not a cam lobe. Having mentioned this though, the lifter rotates so there might be cam as well as this might have a flat spot (if this makes sense)
