my bus had sat for a week in cold weather while i was on a work trip so it was good and cooled down.

im going to track down my DT466 manuals today so I can get them for EC.. the best idea of how big a project this is, is to look at the step by step teardown and rebuild for it.

I have oncommand 2014. data which runs on windows but its huge.. 7 gigs i think. i'll look in that and see if it has the 466E in it.. i think it does.

JB Weld

Long story short?
I slid a 360 excavator in a wet ass ditch and almost on its side and when I went to use the boom to push it out it blew a hydraulic piston cap?
Went to the parts store and of course it had to be ordered and I said that tractor has to be out of there ASAP so they sent me back to a man I knew in there machine shop and he looked at the ear/bolt hole broken off of my aluminum part and reach over on his milling table and handed me a hand full off alum. Millings and said mix it with job weld,bolt everything up lightly with a piece of paper under to keep it from getting into the piston and pull the paper in the morning tighten it up and get it out?
That was almost 16-years ago and that excavator still runs and works flawlessly to this day with job weld.
There's not to many times I use it but when I do I go to a machine shop and get a handful of millings for whatever material I am working on.
Same idea?I ended up working on a backhoe where a new operator put a piece of rebar through the oil pan and the mobile mechanic couldn't get his truck to it so he wouldn't do it.(of course it was a mud hole)
Went to the same machine shop got a handful of steel millings and some JB.
That oil pan ain't leaked a drop in around 10-years.
Not saying it's a permanent fix or the right way to go but if in a bind to fix something like a pinhole in an aluminum waterway I would do it again.
Never tried to be cheap but never really had money either.
That's a crazy-good endorsement. I never used the stuff myself, but I will be picking up a tube after reading about your experience.

Reminds me of this guy

I've never "tried to be cheap" either. It just comes naturally.

I totallt Love it!! and if the darn things dont stay tight I will LocTite them!!

ISIS did suck.. OnCommand sucks but its browser based.. tyou need ie or compatible and need to turn on all scripting abilities for it to work but the info is in there..

I found a brand new sealed DT-466 mechanical manual .. not sure its the same service procedure though.. looks like there are differences on the E v s the mechanical.

pulled up my OnCommand and searched for TSI's on this engine.. and got a hit... I dont have software that lets me print to a PDF reliably under windows.. so i took screen shots.. let me know if you can blow these up and read them..

ill summarize here.. TSI 04-12-23RA. international released a coolant sealer conditioner kit to service engines leaking at front covers..

the gist of it is that ELC coolants were not compatible with the seals on the front covers and caused them to leak.. navistar part number 1850155C92 is a kit of 26 tablets you put in your coolant.. 20 of them for a normal vehicle, 26 for a large cooling system like a bus .. it specifically states to use it only once even if you change your coolant dont apply it again.. and that it does not invalidate any warranty and is designed as a lasting repair...

I also found the manual pages on the front cover removal.. the front half of it is pretty easy pull.. the rear half is a pretty large tear down... you have to pull the head.. as the camshaft must come out which means the lifters need to come out and that requires the head off on this engine.. .. so thats why its a $5k repair its half an in-frame right there to get at the inner front cover... I can see why if you have never torn an engine down before why it might be a daunting task to replace both covers..

I also noted that throughout this engine;s life there have been several front cover replacements.. although the only TSI i saw for needing a new pair is related to a different HPOP and not to coolant leaking.. though ive seen forum posts about an updated cover (as youve seen).. so im sure its a multi-faceted thing.. i didnt read every TSI.. there are a bunch.. as there are for any engine..

I can give you TeamViewer access to that machine if you want to mess around in the onCommand manuals at all until i can get you a copy of the file..
