Could use a little help

Edelbrock Performer Cylinder Heads 50169
^^^^
This is the assembled version of the Edelbrock head for the TJ. For your application you want it with valves and springs installed. It is a direct bolt on to the block. The reason you'd want this is that it is a +25hp bolt on. You might also consider 1.7 roller rockers to get a little more valve lift and about +9hp with a stock cam for $550.

You will need to have the early TJ 6-1 header OR a header instead the 2 piece stock exhaust manifold logs of the late TJs. I'm not sure which exhaust the 2000s got. Late manifold logs on the right below. My compatible headers left. I don't have an Eddlebrock head yet and could possibly end up go a different ported head route.

The newer style horseshoe intake is needed with the Edelbrock head, but I believe all 0331 heads have this. This is what the later intake looks like (air filter intake pipe removed)

Regarding the piston skirt, you can see the good example of a broken one above, but they could also just be badly cracked and making that noise. With the oil pan and girdle removed, you can see up into the back of the pistons. I took these while replacing the rear main seal. You need a torque wrench to reinstall the girdle.

I appreciate you taking the time to posts all this. Am I okay with just doing the head? Some of what you mentioned is probably out of my league to do on my own.
 
Remove the oil cap look straight down. If you see antifreeze bubbling, cracked head. If you see TUPY, the head has been replaced with the later version and a cracked head is less likely.

Go to the Resources section of this forum and download the Factory Service Manual, FSM, for your year.

If the crank and rod bearings are shot, they can be replaced from below in the Jeep. The procedure is in the FSM.

Where is TUPY stamped exactly? I seen a pic last night with it stamped under the valve cover gasket

Oh man, I just looked up that head and it's $1500 -$2000 (I wish I could stick a WOW emoji right here)
 
I drilled mine just behind the front lower control arm mount and just in front of the rear lower control arm mount. I went with a 3/8” hole if I remember correctly. Others have done bigger, up to 3/4” I think. I used one of those deburring tools I got on Amazon to clean up the edges of the holes and sprayed them with ACE rust spot satin paint.

I'm about to go attempt to inspect the frame further. It's causing me anxiety now lol

This.
I paid 3600 four years ago, back when these things were very expensive, for a rust free 2002 Apex from florida. Absolutely beautiful condition rust wise. Intereor seats were junk, motor was rapping, and the transmission was pouring fluid, but, rust free. At that price you can't lose unless you have to pay someone to do the work. I found a motor for $150 and a trans for $100 (both lucky, admittedly), dressed em' a bit, and tossed em in and now its registered and running down the road.

You really can't lose at that price if it's truly rust free. Even today, you could likely sell it for $3k up here (northeast) if its as good as it appears.

Congrats, and have fun!

By the way, I pulled the oil pan off the motor i pulled out, and like most of these it seems, it has broken piston skirts. It's very likely what's going on with yours.

Thanks man, I'm pretty damn stoked about it really. I love the Jeep already. I drove it through the yard yesterday and it felt so smooth with the suspension, nothing like my YJ I had years ago. I'm inspecting again today for rust just to make sure that I didn't miss anything.

Right under the oil fill hole. No need to remove the valve cover.

Thanks, those def look handy. I assume that cannon is online only?

I bought mine online but I would assume you can source them from local auto parts stores or even Walmart. That brand, along with local auto parts stores, will cost you more than something off of Amazon. Just search foam cannon and you'll get tens of options from cheap junk to expensive detailer cannons.

Drill one in the very back at a 45 degree angle:

... but a little bit more outboard to avoid the nutsert.
 
So it looks like you guys were right about the rust inside the frame. I inspected both sides pretty thoroughly and the passenger side was clear of it from what I could tell, other than some mud/dirt in there. The driver side between the front and rear control arm mounts had some flakes. Not thick flakes but some flakes. The from still felt thick it seemed and didn't feel like anything I should get stressed over but I would like to stop it in its tracks immediately and seal it somehow so that it doesn't continue..any suggestions on what to spray or put in there after I drill the holes?

When drilling behind the front control arm and in front of the rear control arm, shouldn't I be looking for the lowest points in those areas so that all the water drains?

And is that very back area that you said to drill the 45 degree hole at closed off or something? It looks like there is a drain hole right on the other side of the nut.

The problem is micro in scale...

The end cross member wraps UNDER the frame. Water can - and does - accumulate in the micro groove between the end of the frame and the inner face of the cross member. I originally drilled a 1/2" hole through the cross member congruent with the inside bottom of the frame. I found this:

I flushed all that out with a bunch of water, but saw the afore mentioned gap/groove at the bottom of my hole. So I did this:

Hogged the hole out so it would be low enough to keep that section drained. Because this ended up being as FUGLY as home made sin, another member here learned from my mistakes and drilled the 45 degree hole previously shown. He in turn recommended drilling the hole further outboard than he did. Thank Goddess this is all hidden behind the rear bumper!

Flush the crap out of your frame after drilling the holes, not only to get rid of what's already there, but to get rid of the drill shavings. After it dries, spray the crap out of it with Rust-Oleum primer, then top coat it too. The above picture hadn't be (re)painted as yet.

YMMV and all that.

After I drill and flush the inside of the frame out, what can I put inside the frame to stop the rust that I did find? I there any type of rust-oleum for that?

And what kid of drill did you use? I started to drill today but that bit did not want to penetrate that steel.

I just used "Rusty Metal Primer", my old standby.

A good SHARP one! ;)

Start small, like 1/8", then work up in size until you get where you need to be. But they need to be SHARP. I have a "Drill Doctor" bit sharpener which is worth its weight in gold.
So when you say a little more outward, you're saying a little more toward the outer side of the jeep? To miss the nutsert but stay at a 45 degree angle?
Correct. You don't have to do the 45, you can drill it straight in then slot it down like I did. But that's more trouble and looks terrible.

I think I'm okay (or say that now lol) to drill at a 45, just wanted to confirm what you meant by outward. Outward=move to the right or left a little (depending which side of the jeep I'm working on) to avoid the nutsert inside the frame?

Use the Eastwood internal frame coating,tape up all holes in frame with blue painters tape.the nozzle has a long hose with holes that spray everywhere.make sure you do it outside it will stain concrete.i did mine 4years ago and it’s still great.
