If your comp gauge doesn't hold, it's probably the check
valve leaking or missing - Same valve as a tire Schrader
valve - use a two-pronged tire valve tool to unscrew it and
screw a new one in. OR swing by a tire shop and ask them to
put a new valve in your compression gauge for you. Cost
should be Zero or very nearly so.
When you do your comp tests: Ground coil hi tension lead or
disconnect positive low-voltage lead from the coil.
Remove ALL the sparkplugs at once. Have a pad to write down
what you get for a high reading. Throttle wide open for all
tests. Turn engine over while watching gauge needle - don't
stop until at least a couple revolutions after the highest
reading. Do all of 'em, then squirt some SAE 30 oil
(preferably, or 40 but you CAN use any engine oil) in half
the holes and spin it over a couple turns. Check compression
on those holes. Squirt and check other holes. If you have
one that is down, put the sparkplug back into the hole NEXT
to it and try the low one again - No change? then put the
sparkplug into the hole on the other side of it and try
again. If adding the plug to the hole either side of the
hole in question causes an appreciable increase in
compression, you have a leak between cylinders - most likely
a head gasket. If adding oil gets you from say, 20psi up to
90psi or similar, expect rings not sealing. Ring problems
don't normally occur in only one cylinder unless something
was ingested and got into that hole, but then you prolly
have a bent valve and a hole in the piston!
I'm just passing through here - my last Jeep was a WW2 and
some 30 years ago, but this IS an inline 6cyl you're
discussing here isn't it? They usually have the intake ports
grouped - that is, #1 intake is the second valve and #2
intake is the first valve. Look at how the exhaust manifold
bolts on - Is there a single "pipe" (I realize it's probably
a casting) at each end and all the other connections are
wider? If so, it goes E-I-I-E-E-I-I-E-E-I-I-E.

Further notes: Do all your checks with the same compression
gauge. Don't expect anything you get to correspond with what
somebody else gets with their compression gauge or a
different engine. You are looking at the relative values on
your engine. When discussing this with anybody else, you
need to tell them what your "highs" are as well as your
"lows." One compression gauge may read 100 where another
one might read 120. Also, when you add oil, don't let a lot
of time lapse before the comp test. Ideally you would squirt
one hole, turn two revolutions, run test; then suirt the
next hole, turn two revolutions, run test. Be consistent in
how you do it each time. Also make a mental note if one or
two take a lot longer to pump up, but get up to a relatively
high value.
Hope I've helped!
