Re: 97 wrangler valve lifters...
I have had rocker noise or tappet noise in mine since I bought it, twelve
years ago. Simon is like one of those old geezers in the balcony of "The
Muppet Show", but in this case he knows what he is talking about. I
wouldn't replace the lifters unless the noise problem got EXTREME, and in
that case I would replace the cam too. That lifter removal tool is probably
in the KD Tools catalog.

Re: 97 wrangler valve lifters...
My lifters were recently giving a lot of noise at startup and I figured
a clean needed or maybe old age....
I then changed the oil and tossed the Fram oil filter in the garbage and
went with a different brand and no more noise...

Of course, it's always possible, go ahead and report back here if you
suceed.
Or if need be report back and we'll help you pull your radiator, core
support, grill, alternator, harmonic balancer, timing cover, chain, gear
set, intake, exhaust manifold, valve cover, rockers, head, lifters, and
finally Cam if things didn't work out that great.
All joking aside, all of the lifter and cam manufacturers will tell you
the exact same thing, of course they want to sell you a new cam to go
with your new lifters (or vice versa). So don't let them stop you :)
