Keep your head up CB, you're creative and resourceful. I'm rooting for you and have faith in your ingenuity!
Thanks man!!!

That pic does raise many questions that make me wonder too. It is very similar to another I think you posted earlier.
That design is definitely looking like a weak point for that engine. Your diesel guy would likely confirm that but they all have weaknesses. At what mileage is this happening and that looks like it was tap water or worse added to the mix?
Could installation be wrong from the outset is my thinking? Bolts come undone and stretch under stress so are these not getting required maintenance? If yours does look like that I would think it would be fairly easy to cleanup and reseal.
What you think CB and others?
How much to buy that used cover?

John

anything to me that requires so much rubber 'O-ring' area on aluminum with coolant under pressure raises questions to me in design.. nevertheless design means nothing now.. gotta fix it.. and use the correct coolant that the dealer recommends from here on out.

I can easily see where if that inner channel gets eaten at all then the gasket gets loose and will leak for sure..

I find quite a few of these out there.. many of them look in good shape..

I was looking for the part number stamping location.. guess what its on the INSIDE where the coolant goes through... oh yeah navistar smart one... cant see the part number without taking it apart.

so the danger in tearing it to pieces is that shaun will give you fits for having it in pieces a long time? you'll get in over your head and overwhelmed and have to pay to tow it to a shop?

it seems the first step would be to get the old cover off and assess.. it could be as simple as that POS rubber O-ring is cracked or bad.. just like the rubber O-rings on the 444E thermostats that are notorious.. (me included had one leak)... same style material..

this is the seal on that cover.. its not a normal "gasket" like you are accustomed to..

https://www.ebay.com/i/112686019286?chn=ps

this cover doesnt look too bad... its a file photo but the guy answers questions so you can have him shoot pics of your exact..

https://www.ebay.com/itm/INTERNATION....c100688.m4649


Navistar dealer can tell you the part number installed on your bus at build and the updated kit.. so you know which covers to look for and which ones to avoid if you just want to replace the front part.

I *think* the updated cover has two casting numbers on it.
There's a NOS pre-update front cover on ebay (i think), that may be something to consider.
This is definitely a stupid design!

Shaun's not just going to give me "fits". He's extremely obsessive and compulsive. If something in his yard doesn't run or move under its own power he WILL NOT stop calling and texting until its gone. So once anything is being worked on, I basically will have to do it ASAP. If I bring it to my own yard, I'll have a day or two at most till the city is on me.

If its really bad and the inner cover is shot, I can get a rebuilt engine for about a grand or two more than paying for the repair on this one.

I don't think its the installation that's the issue. Its the design itself.
Why else would there be an "updated" cover. I want to see an old cover and updated cover side by side for comparison. I bet there's an extra fastener or two and thicker sealing areas, but that's just a guess.

IDk, man. That sucks! Where's the leak coming from?
BTW- if you ever need a front cover its only like $500 for yours BRAND NEW with the seals.

For what the front cover costs to replace you can almost pay for an in-frame for this DT.
