Hi Makis,

The honing was actually on the camshaft journal and not the lifter bore. They were never honed at all, so the tolerances should be the same as factory, aside from wear.

If I at some point had material score the lifter bore, could that cause binding severe enough to cause lifter noise? From the appearance of the lifters they appear to be rotating.

***I've uploaded a video. The quality is a little bit weak. My phone's microphone seemed to change tone and kind of creates a bathroom / tube type effect. But it clearly shows the sound and how it reacts to changes in RPM***

This noise was gone for a few days. It spontaneously returned. And is only present when the engine is hot. No noise on cold start.

Again, I just popped off the valve cover, and no lifter was abnormally soft. I could not depress any of them using the end of a wood dowel pressing against the lifter.
