1993 Grand Voyager 3.0L lash adjusters

So this afternoon I finally get around to replacing the lash adjusters in my
minivan. They've been bugging the hell out of me for years, ticking until
the engine has warmed up especially while going up the hill that my driveway
is at the base of. So off comes the airbox, alternator, valve covers, and
finally the rocker shafts. Old adjusters out, new ones in, held in place
with twist-ties until the assembly is bolted into place. Everything torqued
to spec, new valve cover gaskets and cam end-plugs. I buttoned everything
up, fired it up, and...

.... it's ticking WAY worse! It's LOUD, sounds like one tick per revolution
(maybe 2), and didn't go away once I let it warm up. Before two or three
would tick away until she warmed up, now one or two scream at me constantly.
Figures, it sounds like it's coming from that rear valve cover too. I guess
my question is, did I miss something? Will the adjusters relax and quiet
down, or did I get a couple of bum parts? I haven't taken a close look at
the old parts yet but none stood out as being severly damaged (I was more
worried about keeping the cams in place rather than studying.). Thoughts?
Suggestions? Hysterical laughter?
