1LW series had the problem. But I've seen two 6TS engines with broke cranks also.

This one had to have had a problem early. 2004 build BXS.

Could have had a spun main, something to need a Align Bore.
Keep track of all the plugs you remove, scrub galleys with a brush.
Air doesn't get rid of dirt it just moves it.
The bolts you took out of starter are not the right ones.
You might consider a gear drive starter if you plan to keep truck.
And last but not least new piston cooling nozzles right after you put pistons in.

How did the bearing shells fit in the cap ?
I was taught that they should kind of snap into place. Anyway hindsight is 20/20 and I am glad you’re getting some resolve.

Even the wrong new shells snapped in place
Have rifling brushes for clean up as needed
Nozzles are on order been for two weeks.
Starter was fine before took engine out
Is no starter spacer so bolts by length are correct.

Those friggin starter bolts just need some anti seize. Personally with rifle plugs removed a hot pressure washer
aimed straight in the rifles works well. I just cleaned that 400 C block that way-shiny through the rifles.

Was always impressed with the amount of crap you can find in the oil galleys of some engines. That is why we always removed every one and put a little prick punch next to the hole to remind us there was a plug removed.
The ones that seemed to be the worst were the plugs in the crankshaft! And those could be a bitch to remove. Found a small heating tip right in the center for a few seconds then let cool a bit and most would turn out easy. For the stubborn ones a 3/16 drill down the center then a second hit with the heating tip and most would come out like they were never tightened!

In my opinion, the degree of cleaning a block somewhat depends on the reason for a repair and also what is found in the oil filter after the engine was last run, as well as a couple other criteria. But that being said, in a bare-block rebuild i feel that there is no such thing as too clean

Just back from dropping off Flywheel to Local that will reface it, stopped by carwash cleaned Frt cover, Bell Housing, Front Mount and Starter, Damn Truck would not start as was 16 here last night (7.3 is tired!) used my old Pimpala to haul that much. Better but Not Spotless. Still need to strip plugs from block and ready for similar haul. Did stop by my Barn and plugged in Cantankerous Allis forklift/Farm Tractor, also a Hard Start.

Looks to be on the back of the rear main?
Exactly where you wouldn't see it doing in frame.

Now for the wildest offer been made to me. SUPPOSEDLY a fella south of me has a Big AL Allis Engine(Probably not but could be) more likely a Allis Genset engine but he offered it to me to install HERE in the KW!!!!
May just buy it to have it even as no parts out there For It.

Had one other issue chewing on my brain, obvious when pulled head that 1/5&6 did not ever fire in any of the run time I put on this. NO carbon in upper sleeve regions just oil. So got to digging thru harness and connections and wiring diagrams. NOT certain if is missed Common Ground on Single Plug 6NZ harness or just corrosion or possibly bad connections in existing Two Head harness, does not matter. Just ordered 6NZ style Single plug Engine side and under cover harnesses, less than $600 and NEW, in stock. should be here sometime LONG before engine is back in frame. Eliminates above questionable issues where will only have to blank off Rear Lower Base Valve Cover harness port. P/Ns 202-1060 ECM side, 425-6526 in cover side. Covers needs of Sensors, Injectors and Engine Brake as Only needs, may need to change out SOME sensor plug styles, maybe not.

Productive day
Shined on crank journals some more and cleaned on it better, set it and no 1& 4 mains
Plastigage confirms under .006 clearance on those set the remainder to initial torque have to set up Xmas tree so stopped for day. Do have to get bell housing seal rings as the OE set up and IPD sent gasket before can get it out of my way.
