Project: Struggle Bus - 2006 FS-65

My problem is the inaccuracy of many of the claims. Even when you cited a reference, it was for OIL temp not "engine" ("engine" temp is almost always a measurement of coolant temp, usually in a cylinder head).

Then "google" says t444e had aluminum heads. Well, the engine in question is not a t444e, and even if it was, those don't have aluminum heads (that I've ever seen).


I'm in agreement to not overheat an engine. I'll also say, don't UNDERheat it either. But I digress...carry on.
 
A very good example of why this is a frustrating place for me. A claim was made that was pretty vague, and then "google" crap is sited as a backup for the claim. That google garbage was "liked" by the poster of the vague claim.

I hate to derail a topic, but, how many errors can you find in that google crap?
Please point out the errors and stop complaining like a child!

Oh and since you asked @niklitas what can go wrong at high temps, he shared his experience with his bus, a T444e, that's why I searched under T444E!

Are you saying NONE of those things from Dr google can ever occur?
Are you saying all of it is FALSE?
Be clear now!

Is that your position???

It does say (Lube oil temp), but that's how they referenced max engine temps back in the day in their technical docs. Many times in those EGES books they can be about as vague as this forum when you need to look something up. It literally mentions 156 times the word "Operating Temperature" of the engine but never lists what that should be in the whole book. I know, I searched all 650 pages of it.

The mechanical writers assume anyone looking at these things would know what that means. Their interpretation of Lube Oil Temp also equals engine temp.

The reason the oil value is set to 230F is because if the engine core is also 230, that heat will transmit into the lube oil that is lubing up your engine pistons etc. As i stated prior, temperatures balance. Oil has a property which cools down engine parts by reducing friction, but if the lube oil has reached 230, then the engine itself is also likely as hot.

So it's assumed to be equal to engine temp in the minds of those old mechanics.
 
Additionally, if you search the web about lube oil temps, it references engine temps as well and states not to exceed generally for most engines out there 110 C / or 230F. There are some lube oils that can reach 260, but those are special applications, not mid size/grade bus engines.
 
OP has MBE906
From the MBE-900 service manual
page 9
Coolant Thermostat...
Opening temperature = 81 to 85 C (178 to 185 F)
Normal operating temperature = 95 C (203 F)
A real far cry from 230 degrees F!


This info is, of course, in general and not specific or tied to any isolated or specific event other than Overheating a diesel...

What Happens When the Engine Overheats?​

When the engine runs hotter than usual, the excess heat causes the gaskets and cylinder heads to expand where the fuel enters the combustion chamber. This leads to blown gaskets and warped cylinders, which can cause leaks and injection failure.

Once the engine oil reaches 240 degrees F, it will start to break down, which can damage the oil system, including the high-pressure oil pump and fuel injectors. If the oil deteriorates, it can’t pressurize the fuel, leading to poor fuel efficiency and reduced acceleration.

Once the engine exceeds 240 degrees F, the damage is done, and the vehicle may need extensive repairs.
Hot oil can also damage the HPOP that sends oil to the injectors.
Hot air from the engine can also damage the turbocharger, weakening the spring and wastegate over time so that it opens sooner than it should, resulting in reduced acceleration.

So that's normal operating temps, not the overheating temps. 203 is about normal for all of these engines. I wouldn't even take it to 240 personally, but is there a value in the service manual about Max Lube oil temps? That's what I'd go by.
 
Found in the MBE900 manual:

Several references in here to shut down engine when lubricating oil temps are greater than 230. Same value as on the International Engines.
 
Delete.

If you don't see the errors in the google "answer", then go do some research.
 
Transmission and engine temps were all good, the engine was knocking at 210 on sustained grades once or twice, but cooled down rapidly after cresting the hill.
Well it seems that "knocking at 210 on sustained grades" is not much of an issue if 203° is normal operating temp.
 
Another day, another couple of states down. We switched up the plans and decided to detour down to Abraham Lincoln's birthplace, and then set down for the night at Trail of Tears State Park in Missouri.

To be honest, today was pretty uneventful. Keeping the drive to under 6 hours (Google time) is the way to go. The portable AC is trying it's best, but, as expected, it can't keep up with the heat and humidity that just keeps ratcheting up as we move southwest. We definitely need to leave earlier, so we can get the camper set up and cooled down before it gets so oppressive. Still, this may change our gulf coast plans to hitting the hills and maybe going to the Atlantic. I've only been to the Carolinas once (to get the bus), and I wouldn't mind seeing Kittyhawk. Gotta see what the rest of the fam wants.

I'm finding the bus seems happiest at 55 and under so I'm trying to keep it there. I hate being a clot in the flow of traffic, which is why I've been keeping to the 4 lanes, and keeping an eye out for safe areas to pull off at. Google also got up to its antics of sending down a completely stupid road in order to shave 300 feet from the drive distance. But, I still haven't hit anything I could figure my way through.

I'm working on a list of fixes on the bus and trailer when we get to my buddy's place in Arkansas tomorrow. The parking brake issue keeps popping up, which seems to be an issue with the valve not releasing the pressure. Basically, it feels like the mechanism gummed up, and if I wiggle it and push it in with more steady pressure (I know, phrasing, but I can't think of a better description). I'm also getting sick of the spazing brake controller, so I'm going to fix the power lead and remove the splice to the backup cam monitor since it's acting stupid too.

I've gotta say, this part of the country is just gorgeous. I was trying to think of what it reminded me of, but it really doesn't have any comparisons that come to mind, between the geology (very different looking rocks in the road cuts) and the tree cover, it just seems to hit different. And running up to the Mississippi, I was really expecting it to be more of a flat floodplain, but coming down to the campground it was a beautiful wooded drive.

I didn't get any shots at Lincoln's birthplace, but I got a couple of shots of our luxurious KOA (Kamping On Asphalt), and the rest are from our 'cheap' state park campsite. KOA is like McDonald's, it seems like a good idea, but it's really a subpar version of something you can get elsewhere, and that elsewhere is cheaper too.

No video again today, I was trying to get some driving shots, but the wonderful KY roads almost launched my phone out of the mount, lol. I do want to record the sights, since a lot of people can't get to these places, and like I said, it's just beautiful. That, and i just got a notification that the channel has hit 50 subscribers, so I'm feeling obligated to get over myself and just film something already... starting tomorrow!

I do want to address some comments/questions, but I'm honestly beat and the wifi down here in A Van! Down BY THE RIVER!!! (my 90s kids peeps know what I'm saying!) is crap at best, so I'll do that tomorrow.

KOA:

I bet you had quite the lightning show over the river last night.
 
Nice pix!! Glad you enjoyed your short time in Kentucky. We have a little bit of everything here. Come through my neck of the woods sometime, in the central part of the state.

Yeah, I really like KY, then again, I also am a fan of bourbon, Corvettes, and caves, so i guess that tracks. To be honest, I haven't hit a state I *didn't* like.

I'll be putting up my update for the last couple of days in a minute. It looks like we're heading to St. Louis tomorrow and spending a couple of days at a KOA outside of there. I know, I know, I just complained about KOA a couple of days ago, but we're doing it because the kids are losing it with this heat, and the KOA has a pool. It's also only 4 hours away (so probably 5-5.5) so it won't be as brutal.
 
Sorry for the lack of updates, we got to my buddy's, Kevin's, house around 6 last night and spent the evening just catching up after 3 years or so.

The drive through Missouri was... Interesting! We stayed outside of Jackson at Trail of Tears State Park right on the Mississippi and pretty much on the Illinois and Missouri, and had to get almost to the other side of the state and down to Berryville. The first 2/3 was pretty uneventful, the normal hills, but nothing remotely concerning. And understand, I was a little concerned, since Kevin was adamant that "This is the Ozarks, so if it's too much, you can set up somewhere and we'll come to you." He also said his road was a little tricky, so if I needed to, there was an RV park in town. After he told me that, I scouted some of the route in Gmaps and it looked pretty chill.

And like I said, the first 2/3 was fine. And then 65 got me! I don't know what's up with those grades, but they knocked me down under 25mph at least 3 times, and under 40 more times then I can count. The bus made it up each time, and fortunately, 65 was a 4 lane highway, so people could pass, but I felt horrible looking at both lanes piled up behind me (seriously, if you're gonna pass a slow vehicle, put the hammer down and get around them).

I'm really taken aback by the natural diversity in this area. I wasn't expecting the amount of pine forests we've seen through MO and AR. I was expecting more deciduous forests, like most of PA, and this really brings me back to when I lived near the coast range in OR.

Today, we went over to Eureka Springs and had a lot of fun walking around downtown and walking through the shops. Kevin was kind enough to lend us his truck, since the Struggle Bus would have been a bull in a china shop if I brought her down. Never thought a 2000s Super Duty would feel like a sports car, but here we are. It's a good thing I had his truck, because maps sent me down some crazy narrow road, and then tried to send me down what, I swear to god, was a driveway with a street name. I decided to GTFO, and backed out of the street, when my kids decided it was a good time to point out one of the residents watching us. I go to take off, and since it was on a hill, and I was used to the bus's throttle response, I may have been a little to aggressive and chirped the tires (sorry Kevin!) and the guy just loses it laughing.

But, these 'stupid' reroutes took me up a hill with a view of a mansion. If anyone knows what this place is, LMK. I couldn't find anything on maps, and the shelter the picture was taken from didn't say anything either.

20250719_125908.jpg


After that, we headed out to the Turpentine Creek Wildlife Rescue. This place takes in large cats from DOJ seizures, breeder raids, and similar situations. Many of these cats are actually from the Tiger King of 2020 fame. It's really sad to hear about the conditions these animals lived under and the crap they went through. They also don't make the animals 'perform', or handle them (other then veterinary type things). It's just a really good place. I'll be honest, with 95° temps and heat indexes in the 100s, most of the habitats looked empty. But the admission includes a drive around tour with a guide, and that area was more shaded, so we got to see a few of the cats. I honestly wouldn't have been pissed if we didn't see any, the sanctuary is so well run, and is funded by the tours and donations, that I didn't feel bad about the money going to help them.

And even with all this fun stuff, the real topper was sitting down this evening and enjoying a home cooked Puerto Rican dinner with Kevin and his family. And really, isn't this the point of all of this? And I don't mean Skoolie life, or travel in general. The real point in life is those connections we make. Sorry if this is a little too philosophical for a old gearhead, but maybe if everyone focused more on those seemingly unimportant connections, we'd have a lot less fighting over stupid crap.

I'm not sure what tomorrow will bring, but that's kinda the theme of this trip, I guess. Probably just a quite day since we'll be leaving on Monday. Maybe I'll record some video, I've got some from the sanctuary, including a bit that sounded like a lion about to puke. Any of you cat owners out there know that sound, just imagine with the volume (sound volume, not capacity volume... Ewww) of a lion. We have 2 cats, and we all looked at each other with a WTF expression!

From there, it looks like we're heading for mountains. Which ones? I don't know! All I know is the kids (and Crystal and I, honestly) are done with the heat/humidity down here. The Carolinas are still in the running. I kinda want to see a plantation. I've always loved that style of architecture, even though I oppose pretty much everything else about the part of our history. I'd also like to have the kids learn more about the Civil War era. While we live near Gettysburg, I haven't given it the time it deserves, and we've seen nothing of the south side of the war. So I guess we'll just play it by ear and see what happens!

Oh, and I got a comment about having seen us on the road, so i just want to throw out there that if any of ya'll see us out in the wild, feel free to say hi. Even though I'm kinda introverted and have RAF (the male version of RBF), I don't bite, and it's cool to meet people who like my stories, or just think the whole thing is ridiculous!

Well, as anticipated, today was a quite day at Kevin's house. It's a real shame that the weather just isn't conducive to almost any activity. So, yeah, we pretty much hid out in the camper. I've been super conflicted during this visit, because I know Kevin's going on a vacation soon, and I know how stressful prepping for a vacation can be, so I've been trying to balance spending time with him and his family, and letting them not have to keep us entertained. I'm sure I'm just overthinking things as normal, but we're already trying to figure out how to get out here again during spring or fall. Better weather, and more time to hang out and see things.

The real highlight came this evening. See, one thing I've probably neglected to mention is that Kevin, besides being an absolute tech genius (seriously, if you all need any IT/SysAdmin work, he's your guy!), also has his pilot's license, and his own plan. So, around a half hour before sunset, he takes two of the kids and I on a little tour of the area. Remy and Crystal didn't want to go up, so it worked out well. So he takes us up, and after a little while, he let's Gwen take the yoke and let's her fly for about 20 seconds before she decides that's enough, oh, and it's also her first time in a plane. After that, he did some 60° banks, demonstrated how slow the plane can go, and does some climbs and dives. And then to make it perfect, as we were descending to land, I watched the sun dissappear behind the Ozarks. Seriously, it was almost a transcendental experience. And, of course, my dumb ass left my phone in the camper, and couldn't take any pics or video. No wonder I'm such a sucky YouTuber! Remy got a video of the take-off, so I'll see if I can at least edit some of the videos together and post them up.

Unfortunately, tomorrow we hit the road. It looks like there's no escaping this heat wave, so after much deliberation, we've decided to back track a little bit and head up to St. Louis. Since we can't escape, I searched for campgrounds with a pool in a 4-5 hour drive that's back towards the Appalachians. After much searching and getting only places that either want you to call, or fill out a request form (Seriously, it's 2025, it ain't that hard to implement an online booking and inventory platform, I'm sure Kevin could set that up!), I remembered why I hit up KOAs and McDonald's. I know it's there, and I can just click a few buttons and be done. For the record, I checked Jellystone, and they were 2x as much, so yeah, St Louis KOA it is, lol. We'll be spending at least 2 nights there, since there's stuff we'd like to see in St. Louis. Beyond the Arch, we also have been told to go to the City Museum. If anyone is in the area and sees us, say Hi!

And just so 8 have some kind of pictures to put up, here's a couple I stole from Remy's Insta of the plane

Sorry, forgot the last couple of days of updates. Here's Mondays update:

Well, today was interesting. We had to leave Kevin and Arkansas, and made our way back to the 'Show Me State' (look at me knowing my State mottos). We wanted to get an 'early' start, which is guess we did, since we headed out around 9am. I really wish I had a camera that I could dedicate to driving shots, there's so much great scenery around here.

We did swing by a Buc-ees, not because we needed fuel, but Crystal needed a restroom, and it was at the next exit, so I had to get a shot with the Struggle Bus for lols. From there, we headed up I-44, where we made a surprise pit stop at a place I've wanted to visit since I was a kid, The Uranus Fudge Factory. We never made it as far east as Missouri on my vacations as a kid, so it was always a bummer. If you haven't been here, it will totally appeal to the immature, puerile people, such as myself. Seriously, I knew there'd be innuendo galore, but this place is over the top, in the best way possible. Needless to say, we picked up some fudge. How they managed to pack a pound and a half of fudge in Uranus is beyond me (OK, that's the only one, I promise). We haven't tried the fudge yet, but it looks great! I also got a Route 66 shot glass to add to my collection.

But, it wouldn't be one of our camping trips without a something going sideways. In this case, two things, both with the camper. The first is more of an annoyance, but I need to research if it's something more serious. When we got to the KOA and got set up, after the AC was running for about an hour, it just started missing water out of the central unit. My guess is the condenser (or evaporater) froze up due to the humidity, and when it melted, it poured out from the AC. It hasn't rained, so it's not that kind of leak. It also could be a blocked drain line. It's been working great all trip long, and water is draining off the roof, so it's partially working. I'll probably climb on the roof tomorrow and see if I can see anything. It's only a slow drip if the fan is set to on, but if you put it to auto and the fan shuts off, it'll piss itself like a drunk at 2:30am. We got towels down and a bucket where the worse of the drips are coming from.

The second issue is a bit more serious. So my wife goes into the main bedroom in the camper and asked 'What happened here?' and I look in there, and the wall on the curb side was all busted up. It wasn't like that this morning, and it looked like it had been pushed in. The weird thing was, I didn't see any damage on the front when I disconnected. After dealing with the AC issue that happened not long after that, I went back out and looked closer (and higher up), I saw where the bus had clipped the front of the camper. I couldn't tell you when it happened, I had to make a sharp backing maneuver at dollar general, which was to the right, so that's the only thing I can think of, but I didn't hear or feel anything, and neither did anyone else in the bus. The good news? It has a plastic front cap, and while it's dented and has one gouge from the incident, it doesn't appear to have actually broke through, so we still look to be water tight, the bad news is I now have to be careful of splinters in my head. I also need to be more cognizant of my clearances when backing.

On the bright side, the KOA is pretty nice, there's actually trees, and there's a creek running behind us. It's not perfect, as usual it's next to a highway (well business loop), and it's also next to an active rail line (3-4 trains have gone by since we got here at 5. But the people were nice, it has a pool and some other activities for the kids, and we're not far from St. Louis, so I'm pretty happy with it. We'll see how we'll I sleep, I guess.

Tomorrow, we headed into St. Louis, and at a minimum see the Arch and City Museum. We're under an excessive heat warning, so I don't know how long we'll be out and about. I'm not gonna say 'Maybe I'll record some video' because that always seems to jinx it.
 
Yesterday's update

Well, the heat wave has smacked down St. Louis. We had to scrap the visit to the Arch and City Museum. One of the kids had a bit of a meltdown this morning and by the time things got smoothed over at around 9:30, the heat index was already over 100. I'm going to be honest, i straight up didn't think it would be safe walking around a city in this weather.

So, we decided to head over to Meramec Caverns. We left at around 2, and the heat index was up to 112. The 45 minute drive was rough, the AC is just a hummingbird fart against this level of heat/humidity. But the caves were just beautiful. Yeah, they're no Carlsbad, but it was a really interesting tour, and the 60° temps were just what the dr ordered.

I'm not positive where we're headed next. We're leaning north towards Michigan, but I gotta see what the temps are looking at. I think we're gonna need at least one more resort type stop for a pool, no matter what direction we go.
