I really like the look of that bus. It's still got all the windows, the sides are pretty straight (except for minor dings on the baggage doors) and it looks like it's been cared for. And yeah, I used to drive a 4104 so I have a soft spot for them.
My family was in the autobody business, so, by extension, I was the one who repaired most side panel replacements. MCI's were a breeze, fishbowls, most of the time we straightened lower panels, but 4104's, 06's, and Buffalo's, those aluminum rivet removals/replacements, and making certain the substructure had a nice, fresh zinc chromate or phosphate coating, including the underside of the rivets, was a pain. Better order a few cases of good beer for that part of the Scenicruiser's restoration. If your going to texture coat the dash/switch panel, and area around the rest of the driver, urethane impact coating - base, with a matte-finish acrylic enamel topcoat seemed most forgiving, and held up well. Love those Scenicruisers, tho!
Sad part of an old GM bus, no transmission selection. A double overdrive Allison will make a vintage vehicle run with the new ones. I know, have one in my FC/3208 Wanderlodge, 70 mph @ 1800 RPM.
That is a great looking bus. Would love to see the inside too. Freshen that engine up and the old Detroit will be screaming again!!! Thanks for doing what you do.
Go to an airshow where the Blue Angels are performing. They will do a maximum performance takeoff with Fat Albert. Backs up to the end of the runway, runs the engines up to the WFO position get it rolling and then fire the RATO bottles. It jumps off the runway, climbs out at a 45 degree angle. This is a C130, big airplane and a pretty amazing show.
JATO. Jet Assisted Take Off. Early jet aircraft had to have solid fuel rocket "bottles" fired to get them off the ground with a load. Look up B-47. Almost as much smoke as some the buses on the hill!
Before he bought it the engine was overheated. The head was cracked and was replaced. I suspect a few cylinders lost some of their compression in that incident as well.
As a youth i worked part time in a garage. A glazier came in with his work van which we diagnosed as slipping clutch. He looked around the workshop at numerous broken windows and asked if a clutch change equated to replacement of the windows to which the boss agreed. I imagine you have some similar agreement with Oz.
I used to run a boat that had twin 671s. We made decent speed but you could tell on the back of a swell it wasn’t right. Turned out it had a cracked head and a bad piston or something, thing still cranked right up! Gotta love the ol Detroits
Body and paint for an in-frame seems like a pretty fair swap! I was jazzed when I thought we were going to get just a body work video. The engine rebuild double feature is going to be fantastic. Cheers!
Oz Has a beautiful 4104. What year is it? A fresh rebuild will have that bus flying down the road and climbing hills. May have to flush the tank and limes too. That’s a lot of sludge in the filter
it's got an ALGAE problem , he needs to add some BIOCIDE to his fuel ,, this is a big problem in vehicles that set a lot ,,modern diesel is worse than the old diesel from 30 years ago about allowing algae growth
Isn't it always the case when working on old equipment? There's usually that one bolt that you just have to keep spinning and spinning until the threads grab on, or the heavy part you really need 3 hands to finagle into place. What should take five minutes turns into hours of doing the same thing over again hoping for different results.
I would be curious to see what adding Restore would do for an engine like that. Checkout Project Farm where he had good success on a tired Ford tractor.
Rode a few years in a 1954 model with Del McCoury. That thing was virtually indestructible.. Del ran it for 16 years.. between Greyhound and being a tour bus it likely had upwards of three million miles on it.
Not sure what I like more is the property that these big buses get to visit or the beautiful land. Nah I take the land but do like the flavor of what’s visiting your property. How many fixes have you fixed? As one that gets fixes limp me back to fix the fix. A good buddy (maybe not such a good buddy)gave me some of the Pittsburgh power max fuel additive. now my truck is addicted to that stuff be careful of additives.
I shuddered when he did that clutch dump to make the summit! The tractor was sitting right there to. An in-frame overhaul is one thing but adding a clutch replacement is quite another.
I have a issue on my 4104. In pedal and linkage i think.. i can back up..but forward i cant hardly move it in driveway.. from back its responsive. When on pedal its a turd
I was afraid of the same thing. When he cranked it back up and started to move again I said, “oh no, he’s gonna smoke the clutch”. The good thing was, he didn’t have far to go.
How is it not smoking if it is not running on some cylinders? Where does the unburnt fuel go? Is it possible, that the non running cylinders don't get fuel?
Did that back door go up by itself on one of the attempts to make it up the hill? If so is that something the bus does by itself or did the door just go up? Great looking bus.
Lol full throttle riding the clutch, holly shit it made more rpm doing that and squel went the clutch but it seemed a good clutch, the bus weight and step grade, go the the little screaming demon
Man has no one learned to quick change a gear up a hill or what. I do it all the time with the trucks I drive, There's no gear grinding it just goes straight in ( you do need to do a quick clutch spiking though), but your timing has to be exactly right, it's as quick as an Alison auto & no force involved either. I think it's the sudden unloading of the drive train that makes a quick change possible for a millisecond on road ranger type gearboxes. I drive trucks up & down 1 in 7 grades all the time.
He’s in 1st the whole time. It’s a gravel drive if you hit the hill in 2nd on the governor your going way to fast and if the engine can’t even keep it on the governor in 1st no way are you keeping up in second for more than a second or two.
@@BusGreaseMonkey unbelievably high gear ratio then, in the Mack trucks that speed your doing at the bottom of the hill would be in at least 4th & in 2 nd gear the truck would be lighting up the back wheels in 2 wd on the dirt empty. Now I see what your saying about smoking up the clutch being a last resort with no lower gear. I'm shure the Ausie versions of greyhound was I think an 8 speed road ranger and some had a split diff like a truck and most had v6 Gm's in them but a few had V8's and they flew. I'm shure I saw the V8 GM pull 140 Km/hr one late night when the driver was in a hurry to make up time.They used the diff splitter to climb up steep driveways & dips slowly.
Hello, I live out here in California and I know where there is a field full of old crown busses. If you want to know where they are I can go out to where I've seen them and get the address.
Because they were made by GMC coach division so the GM Diesel aka Detroit diesel was the obvious engine to use... detroit series 50 and 60 are still very common in buses even today. Detroit used to be part of GM FYI... then they got split off.
They also had the Cleveland Diesel division… used to be the Winton Engine Co before they bought it in the late 1930s. They made locomotive engines for Electro-Motive Co. until GM bought that as well and made it EMD. Imagine an engine similar in design to a 12V71, but with 567 cubic inches per each cylinder (later enlarged to 645 or 710 cubic inches). The later engines were labeled EMD when used in locomotives, but for marine use they still used the Cleveland Diesel name.

The threat of the pull of shame from the tractor scared the bus into making the last few feet. Remember hose engines are very proud
He brought his bus to the right place.... just like the song says :)
Our church had the same bus back in the 80’s my Dad drove it. Far as I could remember he was the only one that could. I love these particular models.
It just amazes me how tough these GM 2 strokes are. Running on 3 cylinders.
I bet once they tear it all apart, there's about 2 working cylinders and a bunch of gunk in the engine
I love the sound of those old buses.

I love the color scheme on that bus, it's very understated and crisp !!
Love seeing these old gal's... :) Thanks!
It may not be mechanically right, but the bus is a beautiful example. Greetings from the UK
Beautiful Bus. 👍😎
Nice looking bus!
Sad part of an old GM bus, no transmission selection. A double overdrive Allison will make a vintage vehicle run with the new ones. I know, have one in my FC/3208 Wanderlodge, 70 mph @ 1800 RPM.
I’m thinking about having C.A. Conversions do an Allison 2000 swap in my school bus with a IHC 9.0 in it
That is a great looking bus. Would love to see the inside too. Freshen that engine up and the old Detroit will be screaming again!!! Thanks for doing what you do.
I am thinking it needs a JATO pack to get it up the hill.
How many here know what that's for? B-36 had them , I think.
Go to an airshow where the Blue Angels are performing. They will do a maximum performance takeoff with Fat Albert. Backs up to the end of the runway, runs the engines up to the WFO position get it rolling and then fire the RATO bottles. It jumps off the runway, climbs out at a 45 degree angle.

Man that motor shure looked clean for being weak

King of backing up!!!!

Wow, what a pretty coach ( cant let mine see me type this, it will get jealous!). Thank you for the video

Might need another shop, at the bottom of the hill... 😊
This is the guy that rebuilt his own engine on the curb back when he lived in Indiana. Much to the chagrin of the HOA. I think he's got this.
Beautiful 4104!
attractive bus, and very clean engine. must be as nice inside the bus.
I like the automatic airfoil back door. Good luck on the rebuild.
I’d like to see a performance build on a 671, turbo, aftercooled and that beauty is just the place for it.
From what I could see, that bus looks new. Very nice.
Restriction in the fuel system . Speedometer cable core is a great fuel line plumbing snake.
A good old fashioned swap out of services !
Hopefully the clutch is ok after that....
Body and paint for an in-frame seems like a pretty fair swap! I was jazzed when I thought we were going to get just a body work video. The engine rebuild double feature is going to be fantastic. Cheers!
Laughed at your definition of insanity haha! Love this channel!
Good looking classic.
Well it did make it up under it's own power . . .
Oz Has a beautiful 4104. What year is it? A fresh rebuild will have that bus flying down the road and climbing hills. May have to flush the tank and limes too. That’s a lot of sludge in the filter
Looked like someone hacked a lugie in that fuel filter.
it's got an ALGAE problem , he needs to add some BIOCIDE to his fuel ,, this is a big problem in vehicles that set a lot ,,modern diesel is worse than the old diesel from 30 years ago about allowing algae growth
I’m sorry but I laughed really hard at your “definition of insanity” comment. 😂

I would be curious to see what adding Restore would do for an engine like that. Checkout Project Farm where he had good success on a tired Ford tractor.
I am extremely interested at what restore / cleaning / cetane boosting additives would do to tired AND well running two stroke detroits.
Oh can we get part numbers for his pneumatic reverse? I was thinking of doing a motorized linear actuator... but pneumatic would be good too.
It's been a while since one hasn't made it first try. Should be a mover after the rebuild.
Nicest looking bus I've seen. for a while. Just needs to go as well as it looks.
Full rebuild indeed! That is a beautiful bus the body work looks cherry mint, looking forward to a full tour and history.
Rode a few years in a 1954 model with Del McCoury. That thing was virtually indestructible.. Del ran it for 16 years.. between Greyhound and being a tour bus it likely had upwards of three million miles on it.
May have to rebuild that clutch.
This makes want to bring my motor home just to see if it will climb the hill!!!!!!

That’s a beautiful old bus, and it deserves the chance to get that Detroit screaming again.
Good diagnose,weak cylinder's! she'll be good as new once rebuilt !
I can relate. I am older than the bus and even with full "fuel", I might not make it either.
I have a issue on my 4104. In pedal and linkage i think.. i can back up..but forward i cant hardly move it in driveway.. from back its responsive. When on pedal its a turd
I havent done filters..but im also running out of a can at back.. fuel tank has a leak now
Poor beautiful 4104!
That is one nice looking 4104. Has Oz had to replace any body panels?
One clean bus.
Hes got a bad case of Diesel Bug in his tank! I'd bet the fuel line is like a clogged artery!
Ì work at a bus company which is 65 year's old and they had these kind of buses when I started and they were fun to drive full pining and all 😂😂😂
No SMOKE, give it More FUEL & maybe a Turbo as well
I was afraid of the same thing. When he cranked it back up and started to move again I said, “oh no, he’s gonna smoke the clutch”. The good thing was, he didn’t have far to go.
Well if the driver didn't know his engines condition before the hill he knows it now.
Dyno Hill ✅
How is it not smoking if it is not running on some cylinders? Where does the unburnt fuel go?
Is it possible, that the non running cylinders don't get fuel?
Scott, it doesn't seem like he really has the pedal to the metal?
Curious to see what the rebuild will show
Looked like the air filter restriction gauge had some red showing?!
I think it’d be smoking if there wasn’t enough air.
@@fmccloud Yeah, you're right and it would probably be BLACK smoke, at that!
I like the body on this bus, has a nice front end. That fuel filter was disgusting. What year is she?
Definitely looks like it's not getting enough fuel. Weak/bypassing fuel pump?
That thing's clean and tight
The Bus is sso nice. I like the Windows and bis bug
I was thinking at least half an engine rebuild but if it’s out just make it all new 👍👍
Bus grease monkey is the absolute best on these old Detroit engines only other one i would trust is Detroit WAYNO.
maybe a set of N70 Injections?
in video when first hearing it run, my ears said not all cylinders are contributing equally, by 6:33 my ears were confirmed as still working right. 😁
What about checking the clutch?
I forget, what is the grade on that hill? It never looks terribly steep on camera but I remember you saying that it's really steep.
4104s are the best looking bus after the 3751s like Lenny.
check the air filters
Good job
Did that back door go up by itself on one of the attempts to make it up the hill? If so is that something the bus does by itself or did the door just go up? Great looking bus.
What's the squealing caused by?
Sounds like it possibly wasn't in a low enough gear trying to get up the hill?? I'm assuming it's an automatic transmission?
Manual and 1st is as low as it goes ;)
Lol full throttle riding the clutch, holly shit it made more rpm doing that and squel went the clutch but it seemed a good clutch, the bus weight and step grade, go the the little screaming demon
It might be prudent to alao rebiild the ttansmission too
That fuel system is some kinda biological h*ll!
That bus is going very fast, should 1st gear not be much slower?
It’s only a 4 speed so no.
Clearly a fuel delivery problem, Its not overloaded, Not running coal.
Was that algae in his fuel?
Biological growth
@@BusGreaseMonkey Nasty stuff.

keep the clips coming
Have you had to flush fuel systems on buses? I suspect my tank has algae in it.
IT'S NOT BLUE UNBURNT FUEL SMOKIN' EITHER . HE SHOULDA TRIED LOW GEAR . YOU COULD TELL HE WASN'T LOW WHEN HE TOOK OFF
He was only in 1st gear pedal to the floor
Serious torture.
Took about a year of that poor old clutch
Probably a bunch of soot/fuel in the oil.
Dirty injectors
Plus u need hot engine cold air intake
Crucial
