GT, he had said that he changed all the lifters to try and fix the problem, and no doubt it is possible to get faulty new parts, but it seems unlikely.

RF, you speak for yourself. What you posted is video of the text that I posted: too loose of a lash (and preload) will allow the tapping and in his case in the video, the rocker to pop off when the lifter bleeds down. His fix was to measure and find the range of the plunger in the lifter, then used a shim to adjust the preload to about half of the range, which is about the right preload. Notice he also checked compression on the cylinder to ensure that preload was not too much (valves not closing all the way). And it does actually appear to be the same problem.

This is exactly what I think should be done in IN2H2O's case, but I think he should check them all, to be sure they are all ok.
