    Posted: 18 Sep. 2019 at 12:28am
So I took the jeep off roading in April with a group of flat fender guys in southern Missouri and had a blast but I could tell something just wasn't right as I was burring oil and and just I smelt like fumes at the end of the day. Got home and pulled the head, pistons and valves and found that the valve guides were lost as I could wiggle almost everyone of them. In the mean time I bought a new Gladiator and my Willys kind of fell off of the radar for a while. Long story short, I just ordered new rings, valves and guides and everything else needed but am having problems finding the correct tools.  Spring compressor, guide removal tool and guide install tool.  Anybody have any leads or would be willing to loan them to me, I would make it worth their while!  Also looking for any feed back or tricks on how to proceed with the work.

The only special tools would be a valve spring compressor.
Also a tool to drive and or set valve guide depth.
The driver/depth tool can be ho-made from an old valve stem.
The old valve shaft needs to have the head cut off; then weld a collar on so you can drive in new guides without damaging the guide.
You can also add another stop onto the tool so that guide depth is regulated to exactly 1" of exhaust guide depth below the deck surface. (L and F  head exhaust guide depth)
Put guides in deep freeze to shrink them and be ready to install them with no delay because they will swell back up quickly as you drive them in. 
So that means the guide bores are clean and oiled. 
The tools are right there and handy.
The block should be room temp or warmer.
Hope that helps...

Replacing rings too I see, so will need a ridge reamer, ring squeezer, cylinder hone, and a feeler gauge to check ring gap. If the gap is too small, rings will break, and if the gap is far above specs the engine may need bored to next oversize.

With the valve guides, and rings worn out, the rod and main bearings are probably worn out too.

Were I going as far as you describe, I would just bite the bullet and do a full rebuild.

I got all the valve guides pulled yesterday, that’s a lot of wrench pulling right there!  Will probably put the new ones in this coming week. Also got the ridges taken out and honed the cylinders. I got the new pistons mounted on the rods and rings installed so they are ready to go in. Next I need to track down a valve seat cutter and possibly some reams.

You may not need a valve seat cutter I did not and was able to hand lap my valves and they sealed up good engine fired right up. Be sure you know which guide gets installed in proper hole the first time AMHIK

   Ridge-Reamers !   Omg, they are sometimes needed to remove pistons from worn engine cylinders if wishing to remove out the top of the block. In today's engines, I am just not seeing worn cylinders and ring grooves.
   Decades ago, an old school-bus mech told my father that you could not wear-out an IH engine, but it took forever for rings to seat too. Then on the flipside, it was seldom to find a Ford or Chevy block that didn't have ring grooves on tear-down. Technology has improved things for us and engines run for many thousands of miles before significant wear.

   An old engine machinist showed me how to quickly remove the valve guides with a hammer and punch. Cast iron guides are Brittle. You use punch to drive the guides down, give the bottom end of the guide a good smack with the hammer and punch, and they snap right off. Next, drive the remaining piece of guide on down through the block. Next use a roll-pin punch to drive the new guides into the block, and pay attention to the depth.
   For those of you who do not have access to a ream, just use valve lapping compound and work the valve back and forth by hand and lap the stems to your Satisfaction.   Remember: exhaust valves heat up more than intakes, so keep the exhaust clearances looser-than-tighter.
    
    I always relish memories of using ridge-reamers ( yes I have a petrified one in my drawer ), Piston-knurlers (don't have one yet), and hand-honing the cylinders for good cross-hatch pattern (hones don't work evenly in worn cylinder walls), so I always used Plumber's Cloth (emery-tape) in heavy grit to put scratches in the cylinder walls.
    For good entertainment, go to the website for Hastings Rings, and visit the Tech-Section about "Glaze-Breaking".
The link below will get you to Hasting's page:

I agree with turning the crank and new bearings. Unless you had excellent oil pressure and you pull a cap and things look good. Also, remove the oil pump and use emery cloth on a flat surface to remove the scoring from the pump plate. It's easy to do.  If you have the motor out of the Jeep, you might as well tear it down and clean the heck out of everything and install new gaskets and seals.
