Rubicon Knock Again??
Based on what I know about cars, I'd take a hard look at your oil pump pressure. I don't quite know how the Hondamatic transmission works, Wikipedia wasn't very helpful; but if your oil pressure is high, you may have a partially blocked oil passageway. If it is low, you have a failing oil pump; or a partially blocked return line.
Either way, your failed camshaft and lifters prove that something is wrong, and the fact that the noise is back means it aint fixed.
I would look at an oil pump replacement, and do a complete oil pathway flush to remove any sludge in the lines. Or, just save money for more cams and lifters. You're gonna need it.

I don't know about your Rubi but on the 400ex if you remove the housing on the side with the cam chain you may see obvious wear where the chain has become stretched. I would think that if your cam chain becomes to loose it could remove the tension from the cam and allow it to damage itself as well as the lifters.

If that tensioner was broke I would almost guarantee that it allowed the chain to flop and become stretched. I just went through this process with my bro's 400 last night. His was knocking so when we tore it down the tensioner was broke, when we got the chain off it was about 3/8 inch longer than the replacement. Sounds like we found your prob Rubicon1963! Make them turd heads replace your cam chain!

I don't know how you'll manage that. If it's under warranty they seem to do what they want. I'd just complain about it until they stop the noise. If you don't wanna do it yourself and you give up on the dealership. I'd suggest a non-dealer shop that works on small engines. Hmm..I guess you could stay out back of the dealership until the mechanics get off work and offer them a little cash to repair it on the side. : )
