What did you do to your TJ today?

Replaced the 5.5yr old battery that was definitely showing signs of weakness with an Odyssey extreme battery.

The required pic per forum rules. 😉
 
Those are nice, I have the kit from JeepCables.com. My battery cables and terminals looked awful, so it was easier to replace everything. They seem well made, and it definitely cranks over faster. I'm sure you could make it yourself cheaper though if you have the time.

I snagged the K Suspension power upgrade kit for my LJ last year shortly after I purchased it, mating it with the terminals above as well as a new alternator. Figured that would address any potential power issues. I also installed their H4 headlight wiring upgrade while I was at it.

Finally completed the transmission/brake/steering overhaul.

At first it wouldn’t start, turns out making sure the crank position sensor gets plugged back in is a key step. After that it fired right up.

Let it idle in N for a bit, then ran it through the gears. Then low key freaked out because the fluid level was good but there was no telltale clunk of it going into gear, although you could hear the idle change. Turns out having the t-case in neutral is a factor here.

Net result is we have a jeep that jeep that shifts gears, firm brakes, and a bled power steering setup.


But F ME RUNNING, there’s a drip at the bellhousing, which was the exact problem I set out to solve.
 
That is definitely repairable by a competent, old-school radiator shop, and it looks like a contact wound, rather than a corrosion pinhole, which is good. Corrosion pinholes mean it's likely to see more soon. Is it worth it? Only if the rest of the radiator is in good shape. The common failure seems to be the top plastic tank splitting. Look at that closely for signs of cracking. Here's some posts with pics:

I think I'm going to try to pre-empt my radiator cracking at the top by epoxying on some aluminum or stainless shim stock to add some stress relief for the plastic. I did the same for my door panels, where they typically crack at the top towards the front. So far, that's worked out.

The rest is in good shape but I already have a Denso inbound. It’s a good suggestion though and I’ll get it repaired to keep as a backup.
 
This is from yesterday, but I'm taking a break since it's raining outside.

The timing cover was missing a fastener and the one below it was loose. Someone previously put RTV over the seal rather than replacing it.

The chain was super loose and the guide was in two pieces, so I installed a melling kit that I had on hand.

Replaced the sprockets & chain and then installed the seal and cover. There was no splash guard on the crankshaft. Hopefully, that won’t undermine my efforts.

I cleaned the threads well with many Q-tips and brake cleaner. Used a combination of the Fel-pro gasket and light RTV (The Right Stuff) since the cover had nicks. Going to replace the HB as well since it’s showing wear.

The starter looked as grimy as the timing cover so I cleaned that up as well.

Next up is the rear main seal and oil pump. I just read about the new pickup being difficult to install unless a tool is use (no idea what tool exist for that).

I let the engine drip over night on a trash bag that I mounted with a bunch of magnets to keep dirt out. The bag and magnet trick also works well for covering open axle/differential.

No noticeable heat damage to the pre-cats from running the Banks turbo.

Yesterday, but I'm not ready to work again today lol.

Along the way, someone put the seal in dry but put rtv over it to address a leak.

The tool for oil pump tube.

I have no experience with this, but just happen to come across it. I’d think it would be easy to make for the knowledge and right tools. Or improvising with common tools and hammer. LOL
