here's the deal, I heard I needed to test it when I had the miss fire issue. so I reproduced the miss and tested it, I realized that this is probably causing the valves to not seat properly, so later I am going to test cyl 1 again, my dad said cyl 5 was reading 27, and they just did a test on one of their race car motors (stock car K&N Cup) and it was reading 15 and was fine. so I'm guessing cyl 5 was fine. so if I test it when it is running fine, and it reads that it has compression, I am going to do my best to keep it running smooth with no miss fires (means I really have to keep my foot out of it and change my driving style completely, should be fun to learn really) this will give me the confidence to drive it till I have the money to rebuild...
here is a link to the trouble shooting thread so you guys can get an idea as to what the motor is doing and what we have discussed to try and diagnose thus far...

I think this was stated in my last post in that thread but, for those that don't care to read through that my plan is:
save up, buy a junk yard motor with the same casting codes, immediately pull the head. it will be thermal baked and magnafluxed to check for cracks, resurfaced, new valves, valve job, valve springs, and all that hard ware, roller rockers, the springs will probably be stiffer a bit, I will hand port and polish the head, it will be built for a more performance application.. I will pull my intake one weekend and port match, as well as replacing the header and making sure that is matched up, then swap that head for my current head.
my current head will be set aside in storage.
the JY block will be torn down, sell off what I can to other Jeep owners. of course, I am never the type to screw someone over so I will only sell what is in decent shape after I clean it up really good and possibly even have the crank micro polished, rods thermal baked and shot peened to relieve stress etc. (I like going out of my way to make sure I am really helping someone/ giving out a really good product) the block will be baked, decked .010"-.020" if needed potentially bored out a very slight bit, it will get a 4.2l (258cid?) crank and rods, the crank will be ground .010" maybe, same treatment as the parts I sold, micro polished (happens when it is ground) baked, shot peen etc. higher compression hyper eutectic pistons, head and block will be painted with high heat ceramic paint, same color as the intake so an aluminum grayish... basically build a stroker, and do it right. and clean everything up.
once all this is done, I will rebuild the original motor, keeping it a 4.0l, but it will be completely freshened up over time. then stored in a crate till/if I ever need it...this is the plan anyways...
