Relying on that engine management is like entering an FB group and asking a question. The number of answers you’ll get back will range from reasonably accurate to downright bizarre. The moral of this story is fit two aftermarket temp gauges, ideally with a warning buzzer so you don’t miss the cooking whilst admiring the scenery. All this pain for one poxy thermostat! 🙄
After high school I worked at a Detroit shop in Houston called Stewart & Stevenson. We found some 92 series that overheated would crack the block right across the liner O-ring grooves at the thin section in the block between the liners. After you clean those grooves give it a close look. The cracks were always visible. We also checked thermostats in hot water to verify they opened. Most of the time when they failed they froze in the open position. The 92's were just rolling out in 1977 and we spent most of our time replacing main and rod bearings after DDA redesigned them by adding the large slot across the top shell. Your channel brings back a lot of vivid memories.
Thanks for the opening fault explanation Been wondering why you needed the overhaul (I know VERY little about engines) Just a simple part causing so much damage Seen so many guys sent thermostats to a trash can saying unnecessary You just proved them wrong
I am an old aircraft mechanic and I have a exhaust temp and cylinder temp guage that monitors both sides of the engine. The CHT pickup is a washer that goes under a spark plug or a bold somewhere on the head the egt gauge is designed to do the same under a bolt on the exhaust manifold. This way you can monitor the head temp as well as the exhaust gas to see if you have a dropped cylinder. They are available on line for about $400 for two. They are a great indicator of the type of problem that the Wanderlodge had.
A was with a woman who’s father was a Member of Vintage Bluebirds. He was grandfathered in and allowed to keep his two digit number placard on his new Wanderlodge. I first met him at the Balloon Fiesta in Albuquerque. He drove the Coach from Titusville, FL to Alaska and stopped here in Denver area on the way home to Titusville. Some line fitting had broken from the rough Alaska roads. I’m not sure what part it was, but a place outside of Denver had the part in stock. He pulled a Cadillac Escalade painted to match for his go to town rig. Very nice setup 👍🏻
You, Tyler and Jerry are one hellava Team !!! Just WOW !!! At a "Diesel Shop" and "out of bay" Engine rebuild is around $16k ... betting Jerry got a good deal here ...
Yes. Dual thermostats on this beast. My first thought. Great repair, Scott! Bet you feel more comfortable with the 8v92 DDEC. Good stuff, man. At its heart, it's still a Detroit. You're a good man. Don't limit yourself...i didn't. The electronic stuff is different, but it has the same soul. Hehe, at 10:25? Yes, those are foot-pounds! Love those Detroits! Beautiful Silver 92. Loved seeing Leroy at the startup. Bear's scared of the relief valve sound on the air brakes (compressor), poor guy. I have to get him used to that. Didn't think a 180 pound Saint could be afraid of anything... Glad to see Tyler out there, man. You guys are a real team. Thanks for making yet another weekend great for this old wrench. Hehe. On my good friend's Prevost, 8V92TA, I've been telling him I'll do his bearings soon. It's a labor of love. You guys understand. Looking forward to having a coach of my own soon. I'm 56. You understand. I have a nice FLIR digital camera I use at work. Going to test the Webasto heater soon on that coach. Why? Because it's fun, man. Replaced the electronics on that system last year. I want to be sure it's distributing heat through the block properly. We went crazy with solar as well, three industrial panels on the roof. Lots of fun. MPPT system, he's been boondocking with no issues.
Thanks so much from me n my family for returning the theme song because it is like Icing on the cake! Ps awesome job ya'll R Doin up there! I Luv Detroit 2 strokes!
I've worked on a couple 6v71 &12v71 marine versions. This brought back memories. Penski and Peninsular diesel made a ton of cash selling rebuild kits. We put 14000 hrs on our 12v71 before the first rebuild. You guys could have heard her duel 8 inch wet exhaust howl for miles.
When you are working with thin headed bolts you either need to grind the end of the socket flat or you need to get the special sockets for that purpose. With the tapered tip on sockets you are only grabbing about half of the thickness of the head of the bolts. If I don't have the specific size flush end socket I just take it over to my belt/disc sander and make the end of the socket flush.
Love the channel. Would it be feasible adding a temp guage for each bank of pistons to watch overheating. Prob not too common of a prob but that's a $$$$$ repair.
I think he said he still does the mechanical engine stuff and will even scan the system for info/codes but will not "repair" it. Personally I think he'll just work his way into it. I doubt it's that difficult but I guess that's not what he likes to do.
Buy a decent torque multiplier, (not the cast iron type for wheel nut removal, but one with a reaction bar) I work alone & it's saved me so many times ‼️
I am not a 2 stroke Detroit Diesel specialist, however i have built a few engines and whomever said " It sounds great" , you are absolutely right! That messed with me; After Torquing the main caps, showing no oil pan, oil pick up screen in full view, ............ , forgot to show or say we installed the oil pan and filled it, and then "We are just going to run it for about sixty seconds" engine starts and i like was holding my breath.. Consider me pranked.
Scott you mentioned there were 2 temp sensors on this engine. Is there a way you can install 2 temperature gauges to designate right and left head to get a more accurate readings.
Scott Good night May I Ask this? Did You think about digging a pit in one of the maintenance docks? It may allow one person walk below the buses. Sometimes it makes repair easier Thank You
Short head hex bolts.. require grinding the end of the socket flat to get rid of any relief cuts put in by the socket manufacturer.. i have also had to regrind sockets that get used a lot to work down to fresh hex broaching to avoid rounding over the bolt heads.. yes.. it will void the warranty on the socket.. but that is better than rounding a bolt head.. on similar 12 point bolts.. i have shortened the socket significantly..
Here's a comment for you used to work on the old GM did a lot of 71 and 53 series I noticed due to the aging of the blocks when they're new you need the line borrow them for cylinders and crank didn't get the mileage out of them I know in that situation with the bus what else do you do usually got 125,000 miles out of before you had issues again I don't know what's your thoughts
I know you changed out liners and pistons. I don't know this engine, but why did you remove the main caps? Did you need to remove them to push out the liners?
Cant understand after so long and at last setting up a great workable base he didn't go the extra mile of effort and dig a long pit with solid wood pit boards making life so much easier!
Would it help to put another temp gauge just for the left side engine as you had two in like this or may be the bus suppliers should recall the bus in for new thermostats on both side's
Grabbing the the thickest blade in your feeler gauge reminds me of an old joke. If they made these .001# blades thicker they wouldn’t bend so easy 🤷♂️😏
Owner got very lucky, didn't warp/crack the head or cook the injectors. I'd mod those head temp sensors and put 2 gauges in, Left and Right bank Ever pressurize the cooling system cold and check for liner leaks?
I have to do Fuel Filter changes on Two-- 8V- 92s, if I fill the FILTERS with FUEL is that all I have to DO Will I still have AIR in FUEL lines will i still have to somehow BLEED out Just asking. NEVER have changed FILTERS on these RIGS that I do minor service work on.
Weird engineering. Two thermostats, then averages the temperatures? Doesn't seem to make much sense. Love the sound of diesels in general but those old DD 2 strokes are hard to beat.
I found that utterly dumb as well.. Especially Wanderlodges have a dang near space shuttle cockpit with all those extra gauges, so why not one temp sensor for every cylinder bank (oh, and a warning buzzer).
An extension with a swivel and socket can affect the torque depending on the angle. Adapters will affect the torque wrench setting if the distance changes between the fastener and the torque wrench handle. A straight extension will have no effect on the torque wrench setting.

The sound of a properly tuned 2-stroke diesel is very satisfying!
Looks like torquing the main bolts was truly Foot Pounds.....lol
You earned the Dad Joke of the Day award. The prize is satisfaction.

Man that bus is going to run good as new by the time you guys get done with it.

I really love to see your attention to detail and patience with reassembly!
This engine is getting some badly needed maintenance. Nice work. Sounds awesome.
Thanks for the opening fault explanation Been wondering why you needed the overhaul (I know VERY little about engines) Just a simple part causing so much damage Seen so many guys sent thermostats to a trash can saying unnecessary You just proved them wrong
I don't always listen to the theme song at the end, but when I do it always puts a smile on my face :)

I absolutely love the sound of that engine, I'm not going to lie but I love the smell of diesel exhaust, pre DEF that is.

Hi guys nice to have you back nice job on the wonderlodge sounds fantastic
Well, I would call that repair a great success. Well done BGM.
I didn't see a bit of smoke out of that thing when you started it up. That's a good engine!
You, Tyler and Jerry are one hellava Team !!! Just WOW !!! At a "Diesel Shop" and "out of bay" Engine rebuild is around $16k ... betting Jerry got a good deal here ...
I believe i would've added a left and right bank temp sensors and gauges
Good idea... worth the peace of mind.
Me too on the dual temp gauges.
Yes. Dual thermostats on this beast. My first thought. Great repair, Scott!

I hope you build an inspection pit in your new work shop ☺️
Great video 👍 I definitely would take a impact socket and trim the leading edge off and have a dedicated 12 point socket for the main caps.
Killer!..great job...darn good work........& love the tune in the end...perfect!
Beautiful coach and excellent content!!
A man with a dream came to real life. Pretty damn awesome I stumbled across your videos I'm hooked many thanks brother God Bless
Thanks so much from me n my family for returning the theme song because it is like Icing on the cake! Ps awesome job ya'll R Doin up there! I Luv Detroit 2 strokes!
I'm glad I have a 1999 Cummins 8.3 with a Banks kit that runs great with no leaks! I guess no one cleans an engine be coming to see you for work. LOL
Nice bus, great job, well done.
Must feel good to the owner !

The finished product looked good.
Way to go "Ralphie Boy" I see that "Ed Norton" is doing his part. Alice is now cremating dinner. I enjoy this greatly, Ken
Wow great job guys the engine sounds and looks great
Well done guys, bring another back up to standard.
Another awesome video. Thank you
Thanks for posting. Great video
Boy, Tyler's eyes looked like saucers when his foot slipped a second time from that torque wrench!
Like the new Ft # torque wrench!
Love that fiddle kick off on toms song.
Sounds great!
Awesome job guys!
I bet your customer is very happy. I know I would be, that thing purrs!
Nice job , well done BGM . Stay safe 🇬🇧
Looks like you should have a left and right bank temp gauges since it has 2 thermostats. Good job!! Cheers!
Love the channel. Would it be feasible adding a temp guage for each bank of pistons to watch overheating. Prob not too common of a prob but that's a $$$$$ repair.
Sounds real good
Scott, I remember some time ago you said you would never work on a DDEC....what changed your mind?
I think he said he still does the mechanical engine stuff and will even scan the system for info/codes but will not "repair" it. Personally I think he'll just work his way into it. I doubt it's that difficult but I guess that's not what he likes to do.
Hell Yeah Nice Job BGM Family & Friends
8:30 gives new meaning to foot-pounds.
Buy a decent torque multiplier, (not the cast iron type for wheel nut removal, but one with a reaction bar) I work alone & it's saved me so many times ‼️
Do you ever inspect the cam followers or replace them .just curious.I’m a retired cat tech and have only done some injector jobs on series 60’s
Did you put Highway or Transit rings in it? I know Transit rings will need more time to wear in but they wear longer.
I am not a 2 stroke Detroit Diesel specialist, however i have built a few engines and whomever said " It sounds great" ,
you are absolutely right! That messed with me; After Torquing the main caps, showing no oil pan, oil pick up screen in full view, ............ , forgot to show or say we installed the oil pan and filled it, and then "We are just going to run it for about sixty seconds" engine starts and i like was holding my breath.. Consider me pranked.
I would not let anybody touch my DD except BGM if i owned one.
Music Sound track : Great music song writing Tom Feller. Nice
Maybe it's an overwhelming task but, after this repair, it sure seems worth while to get a temperature gauge up front for each cylinder bank.
Nice repair
Scott you mentioned there were 2 temp sensors on this engine. Is there a way you can install 2 temperature gauges to designate right and left head to get a more accurate readings.
Seriously cool theme song!
👍👍
Scott

Do you wanna switch and give it a try. I'll gladly switch with you haha. Sounds like he tried to throw dad under the bus...😄
good video, keep them coming
Here's a comment for you used to work on the old GM did a lot of 71 and 53 series I noticed due to the aging of the blocks when they're new you need the line borrow them for cylinders and crank didn't get the mileage out of them I know in that situation with the bus what else do you do usually got 125,000 miles out of before you had issues again I don't know what's your thoughts
After you add water and check the liner o-rings, do you pressure check the cooling system before you install the pan?
I know you changed out liners and pistons. I don't know this engine, but why did you remove the main caps? Did you need to remove them to push out the liners?
To replace the main bearings
Dang, she sounds sweet! Great Job, Guys!!!!!
Excellent video
Cant understand after so long and at last setting up a great workable base he didn't go the extra mile of effort and dig a long pit with solid wood pit boards making life so much easier!
That is in an rv site not a work site. Plus i don’t like working in a pit
Did you think about installing a second temp gauge so you could monitor both banks of cylinders independently?
Need a greasy hand print(like that person suggested) to go with the regular Bus grease monkey logo sticker.
This is one reason I use oem or Napa thermostats and water pump lubricant
Would it help to put another temp gauge just for the left side engine as you had two in like this or may be the bus suppliers should recall the bus in for new thermostats on both side's
Grabbing the the thickest blade in your feeler gauge reminds me of an old joke. If they made these .001# blades thicker they wouldn’t bend so easy 🤷♂️😏
Meant.001” oops 🙊
Owner got very lucky, didn't warp/crack the head or cook the injectors.
I'd mod those head temp sensors and put 2 gauges in, Left and Right bank
Ever pressurize the cooling system cold and check for liner leaks?
Great videos!
Have you ever had a liner leak after building the top end up lol? Nothing worse than seeing that drip I know the feeling 😭
Milkshake immediately after startup once because one of those head coolant orings got knocked out 1/2 way when the head went on.
I thought the DDECS still had the wax plugs to show an overheat?
Did you replace all the rod and main bearings? I remember you said th 8-92 rod bearings wear faster than the 6-71 engines.
Yes
Scott where did you get those feeler gauges ?
I have to do Fuel Filter changes on Two-- 8V- 92s, if I fill the FILTERS with FUEL is that all I have to DO
Will I still have AIR in FUEL lines will i still have to somehow BLEED out
Just asking. NEVER have changed FILTERS on these RIGS that I do minor service work on.
Wow! All that due to a Thermostat.....
Do they make a digital torque wrench as heavy , to use ?
I need a turbo on my Dodge that takes two people to install. These small snails we use 🤣
I have an 8v71 that needs attention. How do I contact you?
Weird engineering. Two thermostats, then averages the temperatures? Doesn't seem to make much sense. Love the sound of diesels in general but those old DD 2 strokes are hard to beat.
"Averages the two sensors" Arrg! WHO WOULD DO THAT? Just show the highest reading sensor!
I found that utterly dumb as well.. Especially Wanderlodges have a dang near space shuttle cockpit with all those extra gauges, so why not one temp sensor for every cylinder bank (oh, and a warning buzzer).
Awesome
Geez, how many “foot” pounds do those bolts take?
Why not add a second temp gage rather than average the bank sensors..No way a $5 part should result in a $10,000 loss!
Hay I am looking for a bus. I love Detroit 's also. 6v53 was the most I worked on. MGBYAAIJNA 👍😎
Needles. Necessarily for sewing. The only thing stronger than you is us depends wear them
DDEC doesn't seem like a much better design lol. Didn't you say you don't work on electronics?
For electronics it's fairly simple though
DDEC fixes many issues detroits have... namely idle fuel consumption, which leads to slobbering and also allow for increased power.
@@Wingnut353 thanks. I was kinda being sarcastic, but it's weird that they would just average the two temps. I love screaming jimmies 😁
Why not get the next bigger torque wrench out? Tyler needs a full face mask hockey helmet or motorcycle for that job
how come you stoped going ouy on the road ??
Covid
If he had a Digital Display it probably would had indicated a temperature problem.
I'm sure you compensated for the overly long extention.
Of course. We always try to not use extensions to torque but good luck not using one on there.
@@BusGreaseMonkey Just curious, how many #'s did you add to the scale?
We even more importantly used international compound #2 aka peanut butter on the bolts as well. It’s required for correct torque as well.
An extension with a swivel and socket can affect the torque depending on the angle. Adapters will affect the torque wrench setting if the distance changes between the fastener and the torque wrench handle. A straight extension will have no effect on the torque wrench setting.
Why do DD's use defective gate valves instead of ball valves?
