If you do decide to post your final outcome, maybe you could title the thread "How I Finally Fixed my Engine" or something like that so we can remember who you are and what you went through at the beginning. Also, your photos were excellent (IMO).

Best of luck.
I went to the machine shop before work this morning and discussed options with the guys. We are thinking they will build me a custom Stroker, but havent finalized yet. I will keep the thread going and add more pics as things come together.

It didn't work out for the cheapest route but I may get a Custom Stroker build out of it from my local engine/machine shop. Or I have been thinking about this one-

What do yall think about this? Its not a Stroker but has some improvements.

Remanufactured High Performance Jeep 4.0 242 Engine | eBay

""This engine is a modified 4.0 242 cubic inch Jeep engine. We build this for customers that want more performance than stock but don't want to move up to a Stroker. The engine is built with the compression ratio set at 9.25 to 1 with the same valves, springs and retainers we use on our stroker engines. We have several camshafts to choose from depending on the Jeep and how it's used.""

At least you will have peace of mind if you go this route ... plus, if they mean better gas mileage by "more performance than stock" then that's a positive, too.

4 grand for a stroker? I've been out of mechanics too long. What goes into a stroker? I mean what parts are actually changed to bring the cost up? I know different crank and rods, probably the cam but things like reboring the cylinders should be the same as normal because it's just a different size bore. Just thinking about options because with a vehicle that will never be sold, I'll need a motor at a point in time

If you already got a 258 crank, the pistons are the only part that cost more than a stock rebuild. And cam if you want one

This doesn't really matter for me yet, but don't you also need shorter piston rods so the pistons don't hit the valves/head?

there is a specific piston that has a shorter pin height, for the 4.0 rod.

I'm still kinda inbetween cracked engine block (which imo is very rare, I think 1 or more pistons would melt before the block itself cracks...) and a bad head job. They told you the head wasn't warped but I find that hard to believe after seeing your pictures. Let's take the head off again, maybe the gasket tells us another story....

Tailhole, did anything like this ever happen to a block you treated? I'm not a specialist on the 4.0 like you are so maybe you have some more experience with this.

I wonder if a piston did melt. I did hear a metal on metal sound when I cranked it up after it shut down on me. While cranking it sounded like a piston was rubbing on the block without oil and then once it started, at higher Rpm's than idle, it sounded like someone was hammering on my hood with a metal hammer.

On a side note - the shop I called (on Titan's preferred installer list) wants $1300 to install the new engine, If I go that route.

First I find it hard to believe the head wasn't warped. A head that long that has got hot enough to burn through a head gasket is going to be warped.

Is not to hard to crack a cyl, there not but about 1/8 thick.
When water gets in there and sits it rusts. Rings stick and start building up gunk and keeps packing in, and packing and packing.
then the cyl starts to galled along with the piston. Being there is only 0.0015 clearance between the piston and cyl wall, its going to get real bad real quick. and all that is pushing on the cyl.
Thats just one thing that can happen.

Another thing you might be hearing is a rod. water is not a lubricant. When ever oil is taken away the bearing will gall, once again there is only .001-.002 clearance. It can get bad quick.
Kind of like being at the beach and getting sand in your crack and having to run a mile, Not going to be good. haha.

Over the 20 plus years i've been doing this, I have seen it all, Some times its a simple fix and some times it a long fight.

If a cyl has a crack, there is no problem putting a sleeve in.
or buy a reman short block and turn yours in as a core

I agree, It is probably all of the above combined, warped head, galling... etc

I asked about getting the cylinder sleeved but it was almost as much as buying the one from Titan for $1895, which is new and has better components. They said the cost is only a few hundred different because they would have to pull and disassemble the engine to do the work.

Getting an affordable mechanic around here to assist me is my hurdle for pulling the engine myself. I can do almost all of it but I don't have an engine mount/rack thing that holds the engine so you can pull it and or drop the new one in.

If you have a sturdy garage (or a tree, lol) you can use one of these. Hoist up the block and roll the TJ out of the way.

Will you still be able to run regular fuel with that bump in compression (ebay engine)? What about local shops? It's a lot easier to knock on doors than it is to get resolution via email if you have issues.

91 is the lowest they suggest, but its not my DD so I don't mind the xtra $4 per tank and running 93 in it.

$50... that does sound low for all the work it takes to get to the pistons. Maybe DFW just has high prices

Good thought, I called around and found a place that rents a 2000lb engine hoist for $25/day!!! I think i would only need it for one day.

There is a $350 core charge and shipping on that Titan engine is $400 total.

$200 to get it here and $200 to send my block back... That puts the total at $2645 not installed.

The $350 core charge is refunded if my block is rebuildable.

dude. It is not a hard one to build, really.
You've already got experience with harder part.
If you can get it out. Its very straight forward tear down.

Take the block to the shop, Have them mag it. they will have to remove the cam bearings and freeze plugs, then vat it first. If its cracked, sleeve it. bore it. deck it.
(I said to deck it to make sure its flat, shouldn't take more than .010) make sure you take the main caps and bolts too so that the main bores can be check for size.
Install new cam bearings, freeze plugs, and there two 3/8npt, one in front, one in back. The shop should take care of all that.

Also take the rods and pistons. the shop will press off your old pistons, wash your rods and check them size and out of round, and correct them if needed. then install your new pistons.

Take the crank too. once again have them check it. (size, out of round and run out) regrind if needed or if to bad, get another one.

Buy the rebuild from the shop. unless there just real high. Once the shop has the sizes (block bore,crank size) all the parts can be ordered.

Also take all the parts to the shop to be cleaned. rockers,push rods,oil pan and oil pump pickup tube,valve cover, timing cover, and all the bolts. I've got a spray cabinet and a large basket and can put all that in it at one time, theirs maybe different.

When you get it all back, but it together. You've already got the torque wrench. just need a ring squeezer.

Really, its one of the easiest to put together. If you can pull the head you can do this.
I would like to give you an idea on prices but it seems im low ball'n

I am going to do it. I will pull the front clip, remove all the accessories and pull the engine.... Any hints as to how to remove the front clip easily?
Its going to take me a while but I can do it on my weekends and evenings after work. I will document it with pics.

Did you ever think one week ago that you would be come a "star" ? You've got quite a following here with your upcoming rebuild. This is good viewing with lots of hits on this thread. It's cool to see how you're forging ahead with this project even though it may be your first overhaul.

Hopefully, the pressure of millions of viewers won't get under you skin and cause you to "choke" and drop the block on the floor or something like that. Also, you may have to start signing autographs and marketing stuff out of your garage; hats, T-Shirts, etc. Maybe you could find a relative to assist in this endeavor - someone you could argue with over every little detail just to liven the episodes? Paul Sr and Paul Jr (American Chopper) come to mind .... !

On a serious note, we're behind you all the way on this. Some of us hackers are learning almost as much as you while you go through the process. Those experienced posters who have been giving advice based upon their knowledge and experience are absolutely awesome. Thanks a lot, guys.

It's not necesary to remove all that, if you want to you can take off the grille and head light combo. But you don't have to. Take out the radiator though, they damage easy.

Back in my younger days I pulled a 304 out of a cj. took the cap off, took a chain from the motor to a 4x4 post and me and a buddy picked it up and set it on the ground.

them were the good ol days.

On my lunch break (while reading this) I am actually watching Paul Sr rip Jason a new one about his welding abilities...

Probably wouldn't have felt comfortable jumping into something without Tailhole and Tonycrd's motivational advice .

You are the first guy I meet on a forum that actualy jumped in and did it all by himself, so all the praise is yours and well deserved.

Back to your TJ: If you don't feel comfy stripping the block, take it to your local engine guy or get a refurbished short block. (so a block without the head).

It's not rocket sience rebuilding an engine, but you must work in an area that is super clean (so not on the ground in your driveway) and you need at least one special tool: a piston ring compressor. It's a shame I am so far away, I have all that kinda stuff...



Do you have a metal ruler or can you get one? Then check the head. Lay the ruler on the mating surface and check yourself if it is warped or not. Do the same on the cylinderblock.

Haha, yeah, before we got sore backs and worn out joints (I did that with a 302 T-bird)

I used to do clutch jobs on anything lying on the ground, even on 4x4's...young and dumb... (made a lot of extra $$ though, which was all converted into beer.. )

Nowadays I get realy bad cramps in my hands if I try to wrench on something for more then a couple of hours, getting old sucks...

------->Itsfun00

If you do decide to take it apart yourself, we are here to help you out in any way we can. When you got the block out of the TJ, let's start by pulling the rods/pistons, (you can do that, it's pretty easy, take off the head, take off the sump, take off the rod nuts and push) maybe we find something there already.Do mark the rod bottom caps so you know which is 1 and which is 6!


And I hate it that I cannot edit a post on this forum after 30 minutes. Hello, I am a European, I make mistakes typing in English...
