- This bus overheated and was towed in. Coolant getting into the oil. Detroit diesel 8v92TA inspection and tear down.
Misleading coolant sight glass, dirty radiator, plugged up radiator, coolant pouring into oil pan, rusting piston, corroded head and block surface around cylinder.
I loved Jonathon’s comment when taking out a steel exhaust pipe, have they ever heard of aluminum”. This was an entertaining episode.
Everything on that bus is heavy
@@BusGreaseMonkey That engine is a hot mess! Coolant intrusion everywhere!
That final exhaust looks like 409 stainless. They didn't want to do that part twice at least.
Many many years ago at the first shop that I started off as a helper/apprentice the old timer who I was assigned to taught me that any time you do any engine work you always send the radiator out to boiled and rodded out and that you replace the thermostat(s), water pump, and any hose that I take loose/He referred to it as mechanic preventative comebacks insurance. On a side note I was once burned by a sight-glass like the one on this bus since then any time I do cooling system work I remove and clean the sight-glass as a preventative maintenance
As I was focusing on the water dripping down I suddenly noticed the bolt holes, and then the crankshaft, and realized whoa daddy Houston we have a problem. The sight glass was classic.
I distinctly remember thinking oh a sight glass that works… nice.
Same... oh its dripping off those oily metal parts... oh. no.
Uhhh,... hey Lance...
Hey Scott, I sent you an email on the forum last night. Just bought my first 1960 flxible. Really inspired by you . Could I get an invitation to join the forum ?
@@tylerhenry492His patreon is where it's at. I believe link is in his bio. Also, congrats :)
25 years working on newspaper presses dispite the ink, better than an abused bus engine!!! Love your video😮!!!!!!!
Once I was around huge commercial printing presses and those machines were beasts. My hats off to you for working on those things because when one is down, time is money and the pressure for a fix is on.
I ran a press that had the 4 color printing unit sitting side by side running 2 50 inch webs into one folder. We ran paper through at an average of 30 miles per hour. Harris M3000.
That bus engine ranks right up there with locomotive engines in the crappy to work on department.
Looks like the complete maintenance records will be on one page.
LIKE WATCH THE TEAR DOWN ON A OVER HEATED ENGINE AND SEEING THEM RUN AFTER SCOTT HAS WORKED HIS MAGIC ......
Can you say "Poor maintenance" boys and girls?
I'm surprised it ran at all. My hats off to you Scott, that job is a fricking nightmare and I wouldn't touch it with a 10' pole. I can't wait to see it after you've worked your Grease Monkey magic.
That young man has a lot to learn but he’s being taught by a master technician. Peter Lindop UK 🇬🇧
he is getting an education for sure
love that fuel line replacement....yesterday I could not spell mechanic...today I are one....gezzzzz
On these beasts, neglect can get expensive real fast...
100% preventable failures are 99% of what we fix. 1% margin of error in this study.
That is a beautiful bus!!! Sad it was SEVERELY neglected. :(
I'm surprised that engine wasn't seized up! I guess those old Detroits (when I was driving commercially, we called them Driptoits) really are bulletproof.
Reminded of over 48 years of being a marine mechanic,,tigt spaces. 😂
Man, this engine is in great shape 😂
I was burned by a sight glass but it was on my hydraulic fluid reservoir, I swapped out the electric clutch and pump(I had a spare on board) and still could not move my anchor, then I took off the inspection port on the top of the tank and low and behold low fluid. All I had to do was add some. If I can't see it or dip it I don't trust it anymore. :) That bus was nasty. :)
I was screaming at the TV, "Cut it!"
Looks like an engine out for this one. But Scott will work his magic.
Used to work at a radiator shop in junior high, boss took a job, some big off highway radiator, it was taller than I was, maybe 7x7 feet, made up some braces and stands and spent days unbolting the tanks, rodding it out by hand, power washing it clean inside and out, then all new gaskets and bolts, took me a week or more, what a monster.
That rusty coolant made it look like a gunshot victim was running through the shop.
Looks like a big expensive job. I don't have a bus, but tow campers, I always rinse/wash the exterior of my radiators. They are so important.
Teaching the young man wat you have experienced over the years will make him more confident in his skills as he continues to work on buses 👍🏾👍🏾👍🏾
Love watching your Vidios’s from the uk 👍👍👍👍👍
holy crap!!!! maintenance!!!!
These engines are so tough though its been trough so much abuse and still ran.
That started surprisingly easy despite being down at least that 1 cylinder and likely suffering from chronic overheating along with bearings destruction from coolant in the oil.
Always a good video thanks
So enjoy your fault finding skills Scott
Great video Scott if a hose is that old and stuck like chuck save yourself the trouble and cut it off. Saves your fingers and the wiring around what your trying to remove.
That's what negligence will get you. Great video Scott.
I chased a coolant leak exactly like that in my silver 92. Finally found that one of the o-rings at install two years before had been slightly out of its spot. It took 2 years for it to start leaking and then it just poured
Damn, it’s sad how that wonderful bus has been neglected. They certainly don’t fix themselves!
It seems as though even if the owner has the money and desire to properly maintain them they will have a very hard time finding a shop that can do so properly.
100% Agree
Without knowing exactly what is going on ( when did that ever stop anyone on the Internet?)
Neglect killed the radiator.
The radiator killed the engine.
The Detroit diesel, one of man's greatest contributions to mankind takes lots of abuse
I didn't know Detroit did air cool diesel's
With the state of that radiator, you'd have got more cooling effect from a Wasp's nest! Why do people neglect their cooling systems and wonder why their engines die?! It appears there's as many mechanics who's attitude is "Extinguish a warning light by cutting a wire!" on both sides of the Atlantic, I've had it but normally with brake wear warning systems, not engine condition indicators! Citroen have always been criticised here in the UK by mechanics for the amount you have to remove to get to what you need to deal with, but the way this power compartment is put together makes working on Citroen seem like as we put it in the UK like "A piece of piss!"
It looks like thanksgiving threw up in there😂😂😂 LMBO
Really great video Scott. From what I see, warped deck, and a grossly corroded block. Replace engine.
I been doing mechanic and a industrial mechanical tech, one thing I learn never ever assume something is correct , there are procedure that needs to be followed, one is to physically confirm that it is true no guessing is allowed
When you pulled the red coolant level cover and it was just rust color and dry. I knew that engine was done.. thank god bgm got it.. it needs repairing and updating.
Well, there went the cost estimate..........
A bit more in the preventative maintenance budget could have prevented this.
I would guess $20K for the power train and cooling system overhaul.
@@BusGreaseMonkeywhat kind of coolant goes in those Detroit 2 stroke diesels? Do they take the old school green antifreeze or half antifreeze and half distilled water like a lot of modern gas and diesel engines?
92 series requires an anti cavitation coolant. I have little doubt water used as coolant in this lead to its weakened immune system.
Гигантский радиатор охлаждения! Сколько охлаждающей жидкости нужно залить? Классное видео получилось! Мне понравилось! Круто Круто!!!👍👍👍
Taking the radiator apart is a full days job.
@@BusGreaseMonkey He's Russian. He asks how much coolant goes into that cooling system.
22 gallons
@@BusGreaseMonkey 👍
Hey Scott, I love your channel and I wish the internet was around when our family converted 2 Greyhound buses into motorhomes for my grandparents. Every time you work on a 4104 it brings back some great memories. This is purely my opinion based on my observation from some of your recent videos, as well as my perspective as a former mechanic. When you are working on a bus, and filming at the same time,. have you considered using a tripod? When you guys were pulling that radiator out I thought it looked a little careless to be filming at the same time. That's a massive radiator and if it fell that could really hurt someone, and the cost to repair/replace it could be avoided. Plus it shows that the bus/customer/safety is the priority and not the filming. (But I know the filming is important) Using a tripod would still give us a great view of the job (maybe a better view), it makes the job safer for everyone, I think it looks more professional, and I miss seeing you be more "hands on" like your earlier videos. Again just my opinion and observation.
Boy from the look around that engine you gave us....the dollar bills are going to be adding up fast for repairs....glad I'm not paying for it!
Time to retrofit an overhead traveling crane in the bays...
Need to u use a crack detection dye or magnetic style crack detection on the head. Good luck.
Man what a hell of a mess oh well scott will sort it he always does😊
keep the clips coming
Youre due a head sized wash out station...eh..?
Bio safe scrub solution is available...very nice...can have its own heater element for COLD DAYS...LOL
YOU CAN CHANGE /RINSE AND DILUTE AS NEEDED....
PERFECT FOR YOUR SUPER GREASY STUFF...
Looks like that engine had a high degree of preventative maintenance. On a scale of 1-10 it got a minus 2. That radiator is a total mess. Inside rust in the engine looks like they never heard of coolant with rust preventative. Who knows why all the leaks. A few hundred dollars of prevention will turn into many thousands in repairs to correct all the messes.
Very informative and interesting ! Always good watching.
That radiator is stopped up man. Seems like a lack of maintenance. Those Detroit 2 strokes were some strong and good diesels. I was just reminded of how much more it costs to maintain any diesel for semi trucks and heavy machinery. Looks like the owner will have a huge bill to pay.
Thanks for the video.
Bad day when you need a hammer and a chisel to remove a rubber hose.
Just pull the engine it needs a full rebuild but I know it's up to you and what I see I do it
Whoa...wow.. holy moly.
l'm going with what momma always said,
" if you got nothing nice to say"
STFU.. LOL..
Yep she really says it. Haha
Another great vid. Thanx.
✌️❤️😂
The first truck I ever drove had a radiator like that. I had to get towed to the shop.
Hello y'all from Livermore Ca.

I'll be posting a video tomorrow starting up my 8-71 before winter sets in.
The (current) home of Gillig, I see 😁
I can see the need for inspecting private coaches in the same way that commercial buses are inspected. Even if the safety inspection checks out OK, the inspector can advise the owner that some things are in bad shape and should be addressed. The owner may not know about it and get it fixed.

There's also a couple videos from 8 months ago about a guy that got his bus "inspected" by a certified Indiana(?) DOT inspector at a truck garage and while it passed, it was shown to be anything but good when Scott looked it over. There was even a teté-a-teté between Scott and the owner of the shop (with audio) about how bad it was and the need to make it right plus refund the $150 inspection charge. The owner of the shop basically told Scott to "mind his own business" and if the bus owner wanted to, he could bring it back for his people to fix it...at cost of course.
As in DOT-certified inspectors? They are a joke. No incentive to do a good job when the inspection is compulsory.
That whole engine needs to be taken apart cleaned and have new hoses, clamps and what ever else needs replacement.
Really bad sign when added coolant pours thru the block and into the oil pan or ground if the pan is off. The engine is just the beginning. The air suspension is kaput, and lord only knows what the transmission, wheel bearings, kingpins, strut bushings and brakes are like. Perhaps saving the hood ornament and shoving a new bus under it was the appropriate course of action?
Might be cheaper.
Step 1: Remove license plate
That head doesn’t have the wash marks from the injector firing,looks like it’s been down for a while on that cylinder.
Lots of 'shocking'things to consider...The radiator bottom did it for me....along with everything else
Patch Adams check the head if not cracked or warped new head gasket kit, new main bearings rebuilt radiator ship it !!
I guess it's a good thing smell'avisn hasn't been invented yet
When I see you using a tool one-handed while holding your camera/phone (like when using that pick on that ancient hose), I wonder if using a go-pro on a headband along with an LED light might be more effective & less frustrating for you, and give us a clearer/less jiggly view. Just a suggestion...
This was a well-maintained engine....
And by that, I mean "mechanics" took 1 look, said "Well!", and buttoned it back up. It's at a proper shop now.
i use an rv waste tub with wheels for draining oil
I thought the inside of the radiator looked dirty until I saw the outside of the radiator
Looks to me the engine is cooked big time. At least without a substantial rebuild it will not be any good. Radiator might need lot more work than the engine. If the core is busted it's no bueno.
Looks like a Hey Lance kinda thing ! Probably gonna cost a bit to get up to standards again !
Scott, another example of lack of maintenance. This is one of the worst I've seen. I'm surprised you were able to get it to run at all.
Looks like an utter lack of maintenance, borderline-criminal negligence. Obv they've been running staight water as coolant. Imagining what else is worn out, shot, and ruined makes me cringe...someone was broke-ass poor, or ignorant, that was operating this bus. Lots to uncover in this one. Carry on BGM, making the highway safer one bus at a time!
Wish you would explain more of what you are doing in each video and try not to move the camera as much as you. Love watching the repairs.
I guess as many TH-camrs will tell you, this is a working business and not a movie channel. Work comes first.
Ya hate to see such neglect....
That poor radiator never stood a chance.....
1:26 is that a buttery fly valve for the transmission cooler? Don’t forget to open that back up.
Fuel on hot exhaust pipe......check. Guaranteed to cause major engine fire.......check.
If my life dependent on it , I never be able to put that exhaust back together, even with the video...😮
hi all this Bus is a rust bucket around the enigue
So what cost him engine was that little bitty sight glass that no one ever questioned😢
Just a matter of time. The bus has been very neglected.
That bus has been badly neglected, having run a fleet of more than 80 Detroits all of them V71 series I have to say and we did, that before using a V92 we would rather retrofit a CAT 3406, V92 are junk, not reliable use lots of fuel not to mention oil consumption and leaks, you over heat one of those thing and is done, the seals on the liners will let go for sure. They like to spin bearings too.
I love your channel, but I keep on wondering why they keep using those Detroits, yes the sound great, nostalgia maybe but at the end of the day it will run much better with a Cummins 6BTA not to mention relatability and fuel saving, are they just not worth the investment?
By the way if you ever do keep in mind that the harmonics on a 4 stroke are way different than a 2 stroke, 4 stroke tend to tear tings apart, like the gear box, did find out the hard way. Had to have an harmonics study made an get better rubber couplings.
So with this engine, are all 4 valves in the head "exhaust" valves ? Because the fresh air intake, comes in via slit ports on the side of the upper block, but below the cylinder head mounting area, "2 stroke" style, and with the diesel obviously injected through injectors.
Yes all 4 are exhaust valves
Engine got baked like a christmas ham
Pure negligence and lack of proper maintenance. A MerCruiser dealership once told me that owners who ignore proper maintenance of their equipment which often results in serious damage was their bread n butter for income.
Could you use a couple gallons of something like CLR to unclog that radiator?
Rust = water used only?
WOW does anyone ever maintain their equipment anymore. GEEZ
My thoughts are that if you can afford the bus, and you probably bought it for FAMILY use, then you would and should keep it properly maintained. If not you are putting YOUR family and possibly many other road users in a very dangerous situation. If you can't afford to run and maintain the bus in the first place, then don't buy it!!!
Greetings and a happy and safe 2024 to one and all from the UK.
A cooked 92, I would not trust any of the liner o rings or the heads, it has for sure run with water below the deck.
The preventive maintenance on that thing was none existing wonder what the suspension parts look like
Where is Tyler? Did he leave the hill? He has been absent from all your recent videos
What happened to @indianadiesel?
Are you using the "Speed of Air" pistons for much better economy, emissions and power?
Scott, why not have a pit or hoist to make it much easier to repair the buses instead of crawling around on the floor? It's an additional upfront expense but would reduce back pain and speed up repairs.
Overhead trolly would be easy to install
Overhead trolley would not be very useful on bus work.
Agreed, BGM. A trench/pit, with maybe an air-operated diemakers lift table on wheels down in the pit, would be safer, more comfortable, give much better access, in significantly help with capturing clear video. Not that it's a cheap solution of course, but would surely be a good thing in the long run. I know that service pits present their own hazards, though...
Clearly everything is milky in the block. What will
Clean the radio CRW? Poor neglected maintenance for sure
Is that just a four cylinder motor or one bank of eight?
I thought it’d be a six.
V-8
Liner dropped, liner protrusion
The part # on that radiator has to start with a B A 😅 cuz it's one big a _ _ radiator
does your son still work with you >??i have not seen him for a wile. keep up the good work .
Pretty sure he made the move to work for Lance and do work for Scott when Lance didn't have anything for him. I'm guessing he foresaw Lance liquidating and hightailed. Just my guess. It wasn't a surprise to me when I heard about Lance liquidating, I suspected something was up when The Bus Grease Monkey Jr. was no longer putting out content of his own or in his dad's videos.
@pcspecialistpdx nope you shouldn’t guess anymore. He wanted to get away from turning wrenches. He was looking for something else to do. He currently works an office job now.
@@BusGreaseMonkey Thanks for clarifying that, Scott. We kind of wondered what happened to Tyler. Glad that he's pursuing a trajectory that makes him happy. He's a smart kid and is very knowledgeable around Detroit Diesels. Does he still live on the property in his PD 3751, and did he ever finish the interior build?
Are we betting $20k or $40k needed to bring it up to Scott's level of safety and quality?
Was that bus run on dirt roads a lot? Itblooks a lot like tractor radiators or heavy equipment rads?
