it wouldve never been done unless it had leaked previously and they had access to that TSI... and shouldve applied the sticker.. my guess is it probably never got done.. the nature of a TSI is that it is not a recall so its not widely published out... the only time it is discovered is if someone takes a vehicle to the dealer with said complaint and the dealer searches it.. or the school-barn has the manual set and searched for it.. my guess is that since said bus completed a 1000 mile trip without leaking that this issue never occured on it before.. or if it did, it was quite minor and was ignored.. as many minor coolant leaks in hot climates are blown off.. ie driver sees coolant below add line, has mechanic add some.. (yeah we live in a climate thats in the upper 90s every day.. coolant boils off...) even though it couldve been a minor leak that just never dripped enough on the ground to notice..

it obviously wasnt flooding the ground like it is now or shaun wouldve only made it a short distance before the temperature alarm came on..

and believe me you get an 'E' series engine warm and it lets you know about it.. it beeps and screams and flashes multiple lights at you..

PITA for a busted hose.. but otherwise the engines had issues..

not that the 4100 wasnt one of GM;s WORST blunders ever..

unlike navistar where the DT was onbe of the best in the business..

Was it not ECCB that was talking bout mini wood stoves a little back? If so CubicMini is having a Christmas sale 30% off. Got the Grizzly cheaper than the Cub runs normally.

IDK about using sealant. Seems Navistar didn't want to spend the money to actually fix these engines.
Last time I ever used "radiator stop leak" it did so much more damage than it did any good. I swore it off. I've never had any luck with "quick fixes". Maybe if I were selling the bus...
I don't see how a sealant would stop a leak as bad as this one. the video doesn't fully illustrate how much it loses. Lost about a half gallon taking it a quarter mile down the road.
Man, Chris, you're way better at finding stuff than I am, I tell ya what!

Man, Chris, you're way better at finding stuff than I am, I tell ya what!
im. normally not a fan of sealants in a rad either... this one came from navistar... sure sounds like though that this sealant would be more designed toward a slow leak.. I only found it because I was using the navistar Service-manual system and i searched for anything coolant related.. its not online so it wouldve been tough to find online..
the front half of the cover pull looks straight forward... you dont even have to touch the gears.. so perhaps the solution is you get it apart, look for metal damage on both halves... sure seems like everything im reading is that the rear half doesnt get damaged.. itsa only replaced because of an updated part..

find a good front portion.. install it with correct coolant, AND this sealant.. and be on your way..

Son in law had a cracked block on little S10 years ago. Asked me what to do so we added some sealant and it worked for as long as he owned the truck, roughly another two years. And it was pissin' out like a race horse!

Front cover is a must to get off to diagnose further. I don't think it's the back cover at all except to clean it up. Shouldn't take to long with help so city won't get on your case.

Loved the humour CB re the JB weld for Chris, glad you are back man!

I'll have to find out what's involved in getting the harmonic balancer off. I know you have to heat it AND pray to get it back on.
Is the oil pump inside or outside the inner cover? May as well slap a new oil pump in there while its off, if I can. Anything replaceable that can fail should probably go.

I really need that oil analysis kit to get here. I've only got maybe 20 miles on this oil, though. The old oil is gone. Definitely no visible signs of water/coolant in the old stuff, though.
A compression test and a coolant pressure test should be done. I've had a fine mist of blowby smelling of coolant since I got the bus. Just a fine mist. MAYBE its the hotshots additive I put in the oil. That stuff smells kinda sweet. But I don't think it is.
Could the orings around the water area on the front cover failing cause coolant to get in the combustion area or otherwise into the blowby tube?

My humor returned once the finance minister aka Roxy informed me that, in fact, we CAN afford to fix the bus. Now I'm not feeling so stressed.
I got rid of two projects to get something nicer, newer, and something I hoped would be less of a project.
Whatever it takes to fix this thing, it'll be worth it. Passing Jimmies and Whites on grades will totally make it worthwhile! lol

Whatever you do keep that Finance minister forever!
That oil analysis is critical to this fix, I think it will comeback good as afar as coolant not being in it.
The oil pump would be down in the sump or pan no?
Harmonic balancer might be tough but doable once rad is out of the way.
Once she's done right you'll be doinn 6 days on the road for sure.
I'm even feeling better about your situation from afar, sure wish I could be there to wrench with you man.
