Stuck lifter (I think)
2000 XJ stock. Got a sewing machine thumping click on start up, sounds like a loud chug, goes away after it warms up. Tried Seafoam 1/3rd intake, third crank and a third gas, also did spark plugs. Still making that awful noise. Beside just replacing lifter any advice?

That's where I would begin. STP filters are junk.
Try this also. When you start it up and it ticks, shut it off. wait 10 seconds and restart. Tick gone?

It's beating the lifter and cam if you just keep driving it. It's not normal at all.
I've been down this road numerous times over the years. There are sometimes solutions. Simple ones. Let's have the OP post back their results, eh?

All I am saying is the noise may not be much of an issue, 4.0s are known for having a noisy valvetrain and lifters, it is well documented, and there are many different fixes people have tried. As long as it runs fine, has good oil pressure, and good compression it may not be a big problem.

It could not be a problem til his cam goes flat.

O.P. - Just in case you hadn't visited his site - Cruiser managed a Jeep service department during the heyday of the I6, so you can't ask for better advice than he can offer. (Not to discredit 0tt444e who is a well respected forum member as well). The engine is known to be noisy and last for a long time, but you're worried enough about it to post a question (and it appears join the forum).
My $.02 -
Provide the details and let Cruiser help.
In my life I've been intimately involved with an I6 that ran great after 400k original miles, an I6 that ran great after 300k original miles and my current I6 that runs pretty well with 165k miles. None of them I would ever liken to a sewing machine, (And my mother and grandmother are expert quilters, so I'm no stranger to sewing machines), or have sounded like some engines I've heard that I might liken to a sewing machine.

Its also well known that stp filters are crap, they just look cool.
OP,, I would get a new filter,,Wix or Napa gold..start from there.. Then report back with the outcome..
You could be dealing with a crappy anti drain back valve causing dry starts.
My 95 has zero lifter tick..never been rebuilt or anything.. 278k on the clock,,just saying

This is getting a little confusing
first:
followed by:
reinforced yet again
then:
OK, lets hear the synopsis, you are suggesting that you fixed something that wasn't there?
But the OP shouldn't "worry about it" correct?
Maybe you should sit this one out.
