Hopefully I can stay ahead of the non related postings and offer some continuity to what I am building. In part 1, although I was building a LS engine, we were taking pages to chat about Cummins powered Nissans with AAM axles.

Ya, I know, I don't see the correlation either...

So I left the park over there a couple pages from the end of the mindless chatter, where I was getting ever deeper into this Suburban project. Hoping it does not turn into an "Oil-Change" and returns to being driveable, I press ever onward

With the engine secured to the HD stand I use for Cummins engines, I broke it down to just the short block

I actually started off pressure washing it all again and then spraying some purple degreaser on some heavily gunked up steering and chassis parts. After one pressure washing I was getting down to dull aluminum

Most things look like this AC compressor mount and will require scrubbing and paint to renew them

Flyin6 · « **Reply #3 on:** January 21, 2019, 08:07:05 PM »

Then I pulled off the motor mounts, and the oil cooler lines. Yes, the gasket had been leaking!

Flyin6 · « **Reply #4 on:** January 21, 2019, 08:08:25 PM »

Then the oil pan was removed to complete the teardown

Flyin6 · « **Reply #5 on:** January 21, 2019, 08:10:46 PM »

This oil pan is one rough, crude casting. That junk in the bottom of the sump is all casting flash, a part of the pan original casting! Other than that I found nothing and went about the business of cleaning the inside of the block up. I used a brake cleaner soaked rag and rubbed everything clean, then cleaned the gasket surfaces and cleaned it all again.

Flyin6 · « **Reply #6 on:** January 21, 2019, 08:11:26 PM »

Looking a lot cleaner:

Flyin6 · « **Reply #7 on:** January 21, 2019, 08:13:13 PM »

After cleaning as much as I could I taped it all up and applied several coats of paint

Tomorrow should start the reassembly in ernest if everything goes OK and no one needs to go to the hospital!

Flyin6 · « **Reply #8 on:** January 21, 2019, 08:14:49 PM »

Still undecided about the torque converter. The stocker was getting the job done, but the temptation to bolt something in of greater capacity and a few hundred RPM more stall is pulling at me.

Bigdave_185 · « **Reply #9 on:** January 21, 2019, 08:50:53 PM »

Kobota orange!!! And did I see mention of Cummins? I see that Nissan is putting them in Vans now!

Jk. Glad the motor came out easy and you were able to get the cam out with no fuss. Plus now you can switch to a larger oil pan right?

OK, then, back to the Kubota engine it is! ;-))

Flyin6 · « **Reply #22 on:** January 22, 2019, 07:51:15 PM »

Starting to zero in on the bumper with Bear (Brian). Hey, that's close to bear Bryant...Roll tide!

Going with three different sized holes in the front bumper, 5" inside, 4" just outside of that, and 3" in the flats on the sides for rock crawling lights

He was playing with ideas for a brush guard, but for now, I'll forgo that and just get a bumper/winch on the front to bolster capability

We still have some work to do on the rear, and we have decided to re-install the factory hitch in lieu of Brian's much heavier, and more capable offering pictured below:

KensAuto · « **Reply #23 on:** January 22, 2019, 08:06:37 PM »

That Brian guy is sure professional, using fancy computers and what not. ..bet he works on space ships as a hobby...oh wait, that's the pig sticking guy out west.
Kidding aside, I like the design(s).

Flyin6 · « **Reply #24 on:** January 22, 2019, 08:22:47 PM »

Well like always, I like using talent from right here, like you, Ken as you will see shortly with tonight's post. Yes, Brian is easy to work with and pays attention to detail. I hope that lots of folks see his work here and order bumpers from him.

Flyin6 · « **Reply #25 on:** January 22, 2019, 08:23:38 PM »

So the paint cured out fine. My Kubota engine is lookin' purdy!

I was going to for XJ but it went away before I could. Perhaps with the WK2, since apparently only ARB wants to make a front bumper and no one makes a rear bumper.

Flyin6 · « **Reply #27 on:** January 22, 2019, 08:25:22 PM »

But one thing that wasn't very nice looking is the oil pan. Look at that casting flash. Must have been cast in a russian tank factory!

Flyin6 · « **Reply #28 on:** January 22, 2019, 08:32:01 PM »

Wire brushed, sanded smooth, cleaned and re-cleaned, and painted

Flyin6 · « **Reply #29 on:** January 22, 2019, 08:36:13 PM »

Gave a similar treatment to the other parts and coated the motor mounts with bed liner. Harbor Freight stuff, but sprays like the more expensive stuff

Flyin6 · « **Reply #30 on:** January 22, 2019, 08:38:05 PM »

And oh, by the way, this is the single pesky bolt that caused me to remove the engine from the chassis. Like many of you suggested, it just made too much sense not to!

Flyin6 · « **Reply #31 on:** January 22, 2019, 08:39:00 PM »

Felpro center valley cover gasket kit

Flyin6 · « **Reply #32 on:** January 22, 2019, 08:40:23 PM »

Which included the rubber seals that seal contaminants out of the engine internals while isolating the knock sensors

Flyin6 · « **Reply #33 on:** January 22, 2019, 08:43:41 PM »

That went together easily

Flyin6 · « **Reply #34 on:** January 22, 2019, 08:45:06 PM »

New wiring harness as per Ken's recommendation

Flyin6 · « **Reply #35 on:** January 22, 2019, 08:46:42 PM »

Used some stickems to hold down the harness, then applied a 1/4" tall dam of RTV as per the GM bulletin that Ken also supplied. So, thanks to him, I think the job is done right.

Flyin6 · « **Reply #36 on:** January 22, 2019, 08:49:03 PM »

It's a 6.0L for sure!

Next up the cam/timing cover. Bolts loose for now, snugged after the oil pan install

Flyin6 · « **Reply #37 on:** January 22, 2019, 08:51:27 PM »

Bolting stuff back on...good feeling to reverse the trend line!

Flyin6 · « **Reply #38 on:** January 22, 2019, 09:46:32 PM »

Felpro supplied the oil pan gasket. I applied four small dabs of RTV to the parting lines of the front and back covers where they mate to the oil pan

Flyin6 · « **Reply #39 on:** January 22, 2019, 09:47:26 PM »

Then torqued the oil pan down

Flyin6 · « **Reply #40 on:** January 22, 2019, 09:48:33 PM »

And that is the enchilada for today, get back at it in the morn.

TexasRedNeck · « **Reply #41 on:** January 22, 2019, 10:17:35 PM »

So I guess that means no stroker kit?

Don,

Could you replace the pesky bolt for a 2 or 3" stud or cobblefabricate a longer bolt to make it easier on the next guy that need to reach it and still have clearance?

You could put a stud in there,

But

You still have to either pull the motor, or drop the front diff to get the pan down far enough to get the bolt started, and all the while you can't see what you are doing

Keep in mind, this is the MAIN AND ONLY oil supply for the engine. Get this one operation wrong and you are back to A. Pull the engine.

Secondly, remember Ken's dire warning: Don, there is no other way to say this, your oil pan is now going to leak

I'm only a pilut, and not a very bright one, but that was as clear to me as when my wife told me "If you join the Army again and go off to war, I'll divorce you! Simple easy to sort through messages are the most effective for me.

So, in the end it was the factory bolt with a dab of lock-tite blue
