Might have another problem/project…
I believe our Gen 2 4Runner needs a new/rebuilt steering box. Leaking consistently now. Put a litter box under her a while ago, but she’s getting worse. 240,000 miles though.

Maybe this will be helpful as a tip for removing the oil pan on a CJ Jeep AMC 258 i6 / 4.2l , AMC 258 i6 / 4.2l .
That last bolt (dang sucker) tucked under the passenger side motor mount, is a bit tricky.

I believe, conventionally, the passenger side motor mount is in the way and removing it is the chore.

Instead of removing the motor mount, I took one of my 1/4” drive sockets in 7/16” and I ground it down on the bench grinder to as short as possible. The goal is to get a socket on that sucker.

We all have “junk” sockets. There’s a small space in there, behind the motor mount, to fit a socket. The socket ends up being about 9/16” tall to squeeze in there.

The scale vs a .280 Rem case (same as 30-06). Ha!

That replacement bolt will be a socket head bolt (Allen head).

Interesting !

Wife is in So Cal with the ladies for a girls long weekend. They did a “Jeep Tour”.
Nice looking CJ!

Is that tour out in the Sierra Mountains or in the costal mountains ?

Mar 2, ‘24:
-Been thinking about a very minimalist rear bumper. More of a step up to the back than anything. Have a naked rear now. Swing away spare carrier might come later, eventually.
- I spent a few hours and about $50 to get something that’ll do.
-3x3x1/4” angle with a stubby receiver tube and the d-rings attached. Used the 8 factory bolt holes. Chamfered the 4corners to clean it up. Simple and it’ll work.
-I was thinking that I could always attach a spare swing out to it later, since it’s heavy enough. Would penetrate through the top with the pivot point and get a good weld.

That's a great looking bumper. I'd go with that for sure. Have you sold the OME console you had? If not, I'd be interested in it if it is for sale. Thanks,

They’re in Ojai, which is between LA and Santa Barbara. So, I’d say the coastal hills.

Thanks. That console is long gone. About the only thing left for sale is the dash pad.

-Spent a couple hours and about 10 razor blades scraping off the old gasket residue and crud from the bottom surface of the motor block. Very messy but got er clean.


-In anticipation of a tight fit when replacing the oil pan, (since I didn’t remove the motor mount) I took the angle grinder and shaved a bit of the metal plate and rubber from the inside corner of that passenger side motor mount. Has a bit more breathing room now.


-Cleaned and wire brushed the oil pan and gave it a couple coats of new paint.


-Decided I should probably replace the oil pump while I’m inside the bottom end. Poor little spinner has been grinding through a lot of crud, from the looks of it.

Are you doing the rear main seal?

 

[KRUPP]

CJC,

Yes, I’ll be replacing the Rear Main Seal.

 

[CJC]

Excellent - same products I used but I had to do the upper seal twice. First time used grease, it didn't slide in and tore the rubber. Bought a new one and used Dawn liquid soap on the outer part and it slid right in. The little shoe horn helps to start it. I also loosened a couple rear main bolts. Wish I had done the oil pump while there. All in all not hard, just messy, had to remove my passenger side mount and you are on your back. The Snap UPs really help too.

 

[KRUPP]

CJC,
Thanks for the info. I'll be doing that soon and will post how it goes.

Today I picked up my resurfaced flywheel.
Still have to install the pick up tube into the new oil pump. Then I'll do that seal and then the oil pan.

 

[CJC]

It's looking very nice, good luck with it.
You can see the timing chain with the pan off. I wiggled my finger up in there and it was super loose so I replaced that with a new Cloyes chain. One thing seems to lead to another

Mar 8, 25:
-Oil pump pick up tube cleaned (Hot water, detergent, brush, wire and swab).
Drove it into the new oil pump with the help of a 5/8” open end wrench as a driver.


-Rear Main Seal removed and replaced. This could be a separate topic/write-up on its own. Key here is cleaning the bearing cap and block mating surface & carefully inserting the upper seal into groove. A bit of dish soap on the outside of the seal made it easy.
A swipe of RTV on either side of the bearing cap too, over the “ears” of the seal at the cap’s mating surface.

-Oil Pump installed, with pick up tube.


-Cleaned up the mating surface on bottom of motor block again, along with the 187 bolts for the oil pan.
-Cut my under-Jeep time short today. Very important day tomorrow to prepare for - My wife’s birthday and I have some presents to wrap.

That is one clean bottom.
