What I've learned watching this channel: Old busses are cool Old busses are a nightmare to fix Old busses are a money pit Old busses are awesome I want an old bus 😎
Scott you have already used up the patience of five regular guys. And you have been extremely understanding and patient with Phil as well. He seems to be a pretty neat guy, but he is one of a kind.
Phil knows what he is doing. That engine RPM level is about the same with each acceleration shift. This guys knows his stuff. After all the botched stuff I have watched so refreshing to see a true professional. 😃
These longer videos are awesome. I love the sound of these old Detroits. Thank You for making them longer, trust me when I say I really appreciate every ounce of effort that goes into editing and uploading them.
I used to work in hydraulics for a third party company building machinary and servicing it for the offshore oil/gas industry. If ya like the detroits you would be happy as they use a heck of a lot of detroits out there, they'll scream allday.....
One can only imagine the stories of all the people who rode that bus all the years it was in service. The soldier coming home to surprise his parents, the young girl running away from home, the man moving across the country to start a new job, etc.
Phil seem out of sorts with the engine not firing correctly. Any fuel problems like this you start at the beginning of the flue supply, New fuel,Tank, fuel lines, Flexi pipe, anti confusion connections tests. Phil is lovely gentleman, The knowledge he has, is history , special thank you Phil and Scott's team. You will both sort it out. Bless you all
Listening to the normal rattles as Phil drove gave me a flashback to my childhood on the old NYC 🗽buses with the rattling coin box full of change. Thanks GUYS🚍🔧🐒🎥
Scott and Phil, You guys really bring back memories from when I drove for Mid-American Coaches years ago. When riding along like this, I can still smell the diesel exhaust. Great stuff. Thank you guys!
I think this is the first BGM video I have watched where the driver truly knows how to shift those things. Notice at 17:32 when he realizes he missed instead of just ramming it home he went back to neutral, spun up the input shaft and went again. Good job.
That old fuel definately isn't helping with the smoke issue even with additive, there could be an issue where the line connects to the fuel pickup in the tank or the fuel pickup itself, I had one that had a pinhole rusted through it one time. Those things can be so frustrating to diagnose but there's definitely something your missing. These are the ones that make you smarter in the end though!
I always called those type problems gremlins, you spend so much time hunting the issue and when you finally find it, its so simple and you get a bit mad, fix it, laugh about it and store the knowledge....lol
I commend you for your patience,sir. Sometimes builds will fight you till you pull your hair out, but you've kept your cool the entire time. Great job.
I know you dumped a lot of Lucas in the tank. I can tell you from my experience, that while in the tank of my tractor, my tractor was hard starting and smoked like crazy... I'm not putting the product down, for all I know it was cleaning away just like it should, but it didn't help the performance while I was running it. Your fuel issue's are another story, but don;t get sidetracked by the Lucas.
These videos bring back so many memories. I worked for the dog from 1967 to 1983 and in that time I was in every shop greyhound had from Houston Texas to New York City to Miami Florida to St. Louis. I started at the reman shop at chamblee ga and went to the Atlanta shop in early 80s when chamblee was closed. I also drove the truck that took the rebuilt parts out to the shops and picked up the wore out stuff. Lots of stories and a few nite mares. J.D.Crane
I love the look of that bus, I rode Greyhound some the mid 1960s and rode one in about 1989 for about 120 miles because I sold my car and it didn't make sense to have my wife drive two hours one way to pick me up but I never rode a bus that old. That one may be making you pull your hair out but it is sure a beauty out on the road.
What a beautiful old greyhound! It definitely sounds fantastic going down the road. I’m sure you will figure out the fuel situation, it’s frustrating working the same problem over and over. You are doing a great job👍
Hey Scott, I had the same problem with my 5302 I pulled the fuel tank, the pickup tubes were rusted through. I replaced them and problem solved! Check the tank! Go luck, love these videos Thanks
Very impressive gentleman. Good driver. A stickler for the details. The ideal bus man. Hearing this bus travel and switch gears took me right back to my childhood and the public buses we road everyday, which were GM city buses in Oakland, Ca. The way the bus squeaked and jiggled (often it was the seats, which were overbuilt) yet the power underneath as the bus driver (who we knew by sight) switched those gears and operated the bus like it was part of his own body - it takes me home to that time in the early 1970s. I road the bus to school everyday. It was the #59, which drove up into the windy foothills to deliver us to our brick school house in the flats. And then returned us home 6 hours later, which seemed like an eternity then. Who knew how precious those times would be in the distant future?
My grandpa drove till he was in his early 90s he hit a lot of things cars, fences, ditches, his house, etc, but he loved to drive so they let him drive!
Love the way he's maxin out those RPMS, that truly is an old greyhound bus. Since watching you and your crew I have learned a lot and cherish the knowledge, starting to like the bus as a home on wheels.
After watching your video of you at Phil's house and seeing the picture of him in his junior high class picture and doing a bit of math I put his age at roughly 86-87? He is doing fantastic and he drives like he is in his 40's! Great guy to hang around with a talk to and he LOVES to talk! I am thinking the same as others about the old fuel and also air in the lines causing the smoke. Not to mention the massive amount of additive Phil dumped in there. I think a dump and flush of the fuel would work wonders and also a check and replacement of the lines from the tank to the engine.
I remember Christmas 1969 a bunch of us loaded up at Ft Leonard Wood Missouri to go home for two weeks before heading for Vietnam to Charleston WV and the driver said I've got a thermos up here and when we stop for lunch you guys keep this thermos full and we'll make Chas in 10 hrs...and that was before the interstate was completed..and we sure as hell made her in 10 hrs and ever since then the best I could run a Big Rig from Chas to St Louis had been 10 hrs and Ft Leonard Wood is another 2 hrs...Man we flew in that Old Five Speed manual...lol
Scott, you’ve got a lot of things working against you. Old, dirty fuel which probably doesn’t burn right. Old injectors, old style filter canisters, used valve guides and head. Any number of places for air and oil leaks. I would replace the old style filters with a good separator and spin on filter. Drain the old fuel and put in fresh clean diesel. Put in all new injectors.
@@gilbertfranklin1537 - That's the problem. Always trying to do things on the cheap. Why rebuild an engine and use old worn out injectors and other parts? Why fight those old rotted fuel lines for so long? Why overdose old stale fuel with too much additive which can do absolutely nothing to improve the fuel quality. There's an old saying -"Penny wise and Pound (Dollar) foolish". I think that describes this repair to a "T".
@@flick22601 If I had to use the old injectors, I would had them put on test stand and at least know good or bad. Detroits are fine motors but they can be touchy in the fuel department.....
Sounds like the Apollo 13, only kidding Scott, blue smoke is also old flat fuel specially if it's cold. Put some old fuel and new fuel in cups and watch the difference in viscosity. The 6-71 generator I got running had 40 year old fuel in the day tank, i pumped it out and carried it out of the building 20 litres at a time, all 500 liters, before tipping in 200 liters of fresh fuel. It made a huge difference to the exhaust smoke. The old fuel smelt like turpentine and was oily viscous not like diesel at all.
Hi Phil, Enjoy watching you drive. The sound of that 6-71 is beautiful. I drove for TCL back in the 60s, and I think you were one of my trainers. I hope to get back up there this coming year. The last bus I drove before going in to the USAF was 1399. Sure on May 3rd. Stay well.
I've had bad injectors installed during an overhaul wash out a cylinder liner really fast, depending on how bad the injector is leaking or misfiring, it doesn't take long to screw a cylinder up. We had a Detroit Diesel Shop rebuild one of our 6-71 inline generator engines and let it idle way too long without putting it under a full or near full load and for the next 26,000 hours that engine used at least 1 gallon or lube oil every 24 hours!
Phil shifts that bus like a surgeon, precise!!! I thank you Scott for letting go on the rides with him driving. I'll bet he's 18 again behind that big ole wheel!!
Pretty much the same problems we had once with one of our Leyland buses some years ago. Swapped out the injectors just to be sure. No fuel issues, no dirt or clogged filters. Finally, we replaced the fuel pump. That did the trick. Afterwards, we had the faulty pump checked and it turned out to be way out of specs due to.......modern diesel! The lack of sulfur made it to wear out way faster. So on our older buses, we add additives every three fill ups or so. Until now, no problems whatsoever. Greetings from Holland. Willem.
Perhaps it is Phil who is reluctant to change injectors, but Scott IT NEEDS 6 NEW INJECTORS! and new fuel!!! I've been doing these Detroits for 40 years and I can tell you that stale fuel and a bad injector blowing combustion pressure into the fuel galley will cause many of the problems you're seeing.
The fuel pump itself can sometimes suck air also. If there's no air in the strainer and air in the filter that would be a suspect, a crack or a bad seal.
@@toddde6997 - but the air is being introduced on the suction side of the fuel pump. I agree with others and think it is probably between the fuel pickup tube in the tank and the filters.
If the tires were not old enough to vote I would over inflate them by 10 or 15 pounds and then up put a couple of hundred on them because those tire are D shaped to square from sitting for so long. If the tires are not to old most times you can drive them back round but when they get old “square” tires it has been my experience they tend to slip a belt which means if they are not changed very quickly you are going to have a blowout sooner than later.
Steering was OK. Someone had adjusted right side steering stop pin out too far to keep back of right tire from rubbing brake hose on right turn. Repositioned brake hose and reset stop pin. Perfect now.
Not sure how I hadn't watched this before! I have a '52 MoPac 4103 that has been partially converted in Northern Minnesota. Would like to find one to compare against considering a previous owner completely wrecked all of the electrical. Thanks to this video at least I was able to see the fuel shut off solenoid placement! Thanks!
When you were using compressed air to blow fuel from the tank to the back the flow did not look right. At the time it looked like something wrong with the pickup or the line to the back. I would try to run the supply and return into a temporary container and see if the issue goes away. The smoking could well just be aerated fuel causing late injection timing.
My thoughts too. Some Mungrel put a small amount of sawdust in my fuel tank (like a hand full) which contaminated the fuel so bad it near on wrote the fuel tank off by the time I found it (Rust in the tank from it) & caused problems like seen here.
Scott A good dose of seafoam seems to really clean the system out. We used it on a ford 6.4 with 200k on it and after a couple hundred miles it ran smooth. We added it to the oil and after 2 changes the lifters quieted down and now 6k later it still runs smooth. I believe in that crap. Magic. ( like STP!!lol)
We were faced with the very same problem, minus the smoke that is. Culprit was the fuel pump. Pump worked fine at idling but as soon as the accelerator was pushed, one of the plunjers obviously stopped working or failed to deliver the required amount of fuel. It drove us mad, so much time we had spend on that bus. We had the pump overhauled and it turned out the faulty plunjer had a broken spring. Fuel issues can be difficult to deal with. But we learned...
Hola Amigos soy mecánico pensionado y me encanta ver que ustedes son genios en Detroit como me encantaría saber tanto como ustedes de esos motores los felicito soy de Costa Rica Saludos. Todos ustedes 👍
At 18:15 looks like a lot of air sucked in from the tank. Looks like it is coming in on the very right side then to the top of the sight glass, over the top and directly into the filter. There should be none. Every bubble of air will cause a problem and add up in short order.
I'm in Alaska and it's warmer here than there. We had a very light snow weeks ago then it warmed back up the next day and melted. Ya you have got to get that fuel system cleaned out. No telling what all is in that fuel system clogging stuff up.
All the hassle with that ancient fuel system.. first thing I would do is bypass it all with a jerry can of diesel right into the pump. Then you can isolate engine / fuel system. Good luck! There's lots of work to do on an old detroit.
Scott- Have you considered a fuel restriction either pickup tube or an obstruction floating in the tank? Those Detroit’s have very strong fuel pumps pinch off fuel supply and it will find air. Might be time to run it off a Jerry can and rule out supply. Also I would not worry of smoke color. The air box Is still dirty, you have old fuel, with lots of Lucas! I would avoid idling until it is broke in. (It could be already they don’t take long, 1/2 hr on Dyno is all we did).
Yep, Phils injector tester will be very handy . There's more to testing an injector than belting it to see if it atomises ,especially if there is a worn or broken spring, worn pintles, blocked nozzle offices etc etc all of which can conspire to fool you when you are trying to sort a dead cylinder.
I’d run it out of a boat tank/gas can to isolate the rest of the fuel system. I’ve had a lot of experience with trash in the tank sticking to the fuel pick up, then when the engine quits, it will fall off and the engine will hard start but run ok for awhile. Also, Jimmy’s are hard to seat rings on if you can’t load them heavy right away, I’ve had best experience with F.P. kits but even then if you can’t load the shit out of them it’s a bit of a crap shoot. Thanks Scott I do enjoy your videos, Will
Aside from a cracked fitting or pickup tube allowing air into the system, the only thing left in the chain left unaddressed for fuel starvation is the mechanical pump itself. It might be too worn to maintain constant pressure, thus causing the system to lose it's prime over longer run cycles.....would be great to monitor inlet and outlet pressures over a run cycle.
I think the pickup tube in the fuel tank has a rust hole from sitting and needs to be replaced. Friend's 4104 conversion started running out of fuel once it got below 1/2 a tank. Once he decided to pull and replace it the engine purred like a kitten. After the replacement he was able to pull the fuel level down to the bottom of the gauge and still it ran fine. After he saw your video of replacing two fuel filters with one he bought and installed the clear one with and electric pump for priming the fuel system. Simply carries a couple of extra fuel filter kits with him.
24:00 There was no charging problem. The heater fan switch was on and I know one of the two motors is stuck, drawing excessive current. I don't know why the hell neither of us noticed the one fan running, it's obvious in the video. I knew this because I went thru this last year when I thought something was wrong with the charging system, and then I forgot. I am disconnecting the fan switch until I can get to the problem.
37:17 "This was filled with fuel, this was not" pointing to the filter on either side of the pump. Replace the fuel pump. Then check the supply line coming from the tank. You could leak-test it by disconnecting it from the tank, plugging one end, then doing a leak-down test from about 50 psi...
The Gm Greyhound Bus you are working on , i have to say I really love that bus. I would like to know are there many of those buses available? Beautiful Bus. I would like to own one like that one...
I don't know anything about engines but these videos are very therapeutic.

2500 rpms and only 4 gears got to be a Detroit
It felt like he ran first gear out a bit too long.
The auto-generated captions at 9 seconds concluded that a 6-71 starting was applause.
I couldn't agree more.
I absolutely LOVE the sound of those old GM buses! Brings back a lot of memories of the many miles I rode in one when I first joined the Army.

Me too! That's the bus I rode to high school back in the 60s. We always waited for the "old" bus with our old driver... it was the best ride!

No doubt truth spoken here.
agree , replacing bad fuel injectors with old used ones , not gaining ground .

hi another outstanding video thanks for sharing please keep them coming bob
Out the door and foot to the floor.love the way Phil drives them.

This is the most down I’ve ever heard you. Keep your spirits up!
If you want to get a good look at the atomizer pattern from those injectors try filming them at 240fps for a slow motion playback.
Great videos! 😃👍🏻
Maybe a fuel pick up tube in the tank, rusted out or cracked ?? I feel Forya
Has he mentioned the tank yet? I don't recall that he did.
The fuel pump itself can sometimes suck air also. If there's no air in the strainer and air in the filter that would be a suspect, a crack or a bad seal.
@@toddde6997 - but the air is being introduced on the suction side of the fuel pump. I agree with others and think it is probably between the fuel pickup tube in the tank and the filters.
But why would the primary be full and not the secondary if it was the tank? Crack in the Secondary casing or bad seal? Pain in the caboose.
By eliminating the fuel tank and it's fuel lines and drawing fuel off and auxiliary tank you would know about where the problem is
The lovely sound of a screaming Detroit love it
Things I don't want to hear while riding in anything - "Somebody's had the steering apart and put it together wrong."
And then driving it at 70 mph with bad tires to boot. Let me off this thing.

My thoughts too. Some Mungrel put a small amount of sawdust in my fuel tank (like a hand full) which contaminated the fuel so bad it near on wrote the fuel tank off by the time I found it (Rust in the tank from it) & caused problems like seen here.
The old guy is one hell of a good driver
Scott A good dose of seafoam seems to really clean the system out. We used it on a ford 6.4 with 200k on it and after a couple hundred miles it ran smooth. We added it to the oil and after 2 changes the lifters quieted down and now 6k later it still runs smooth. I believe in that crap. Magic. ( like STP!!lol)
I think you are right Scott.. I think new injectors are going to clear it up..
We were faced with the very same problem, minus the smoke that is. Culprit was the fuel pump. Pump worked fine at idling but as soon as the accelerator was pushed, one of the plunjers obviously stopped working or failed to deliver the required amount of fuel. It drove us mad, so much time we had spend on that bus. We had the pump overhauled and it turned out the faulty plunjer had a broken spring. Fuel issues can be difficult to deal with. But we learned...
Hola Amigos soy mecánico pensionado y me encanta ver que ustedes son genios en Detroit como me encantaría saber tanto como ustedes de esos motores los felicito soy de Costa Rica Saludos. Todos ustedes 👍
Love that screamin’ jimmy! Driving it right!
At 18:15 looks like a lot of air sucked in from the tank. Looks like it is coming in on the very right side then to the top of the sight glass, over the top and directly into the filter. There should be none. Every bubble of air will cause a problem and add up in short order.
I'm in Alaska and it's warmer here than there. We had a very light snow weeks ago then it warmed back up the next day and melted. Ya you have got to get that fuel system cleaned out. No telling what all is in that fuel system clogging stuff up.
All the hassle with that ancient fuel system.. first thing I would do is bypass it all with a jerry can of diesel right into the pump. Then you can isolate engine / fuel system. Good luck! There's lots of work to do on an old detroit.
Exactly. Renovation of the fuel system including the fuel tank should always be job 1.
That peeling dash and A pillars would look fabulous scuffed and smoothed with a Scotch Brite pad and then a thin coat of boiled linseed oil.
Phil knows how to drive a bus...Still a Rebel !!
Phil knows how to rev up that bus!! LOL
Scott- Have you considered a fuel restriction either pickup tube or an obstruction floating in the tank? Those Detroit’s have very strong fuel pumps pinch off fuel supply and it will find air. Might be time to run it off a Jerry can and rule out supply.
Also I would not worry of smoke color. The air box Is still dirty, you have old fuel, with lots of Lucas! I would avoid idling until it is broke in. (It could be already they don’t take long, 1/2 hr on Dyno is all we did).
Phil sure can drive those old Detroit Busses...!!! He loves to get them revving high... lol. they ARE 2 strokes....
Man you still have a ways. To go. Come a long way already
This bus just purrs. Nice ride.
Yep, Phils injector tester will be very handy . There's more to testing an injector than belting it to see if it atomises ,especially if there is a worn or broken spring, worn pintles, blocked nozzle offices etc etc all of which can conspire to fool you when you are trying to sort a dead cylinder.
I’d run it out of a boat tank/gas can to isolate the rest of the fuel system. I’ve had a lot of experience with trash in the tank sticking to the fuel pick up, then when the engine quits, it will fall off and the engine will hard start but run ok for awhile. Also, Jimmy’s are hard to seat rings on if you can’t load them heavy right away, I’ve had best experience with F.P. kits but even then if you can’t load the shit out of them it’s a bit of a crap shoot. Thanks Scott I do enjoy your videos, Will
Awesome bus, it still has the greyhound logo on it,👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻✌✌✌✌✌✌✌✌✌✌✌
love the sound of these old twostroke diesels.
Very nice bus!
Start at the tank and work back. My guess is a worn or chaffed rigid line or pick up tube,
This is my guess as well.
That's what I was thinking also.
Marvin Wegner looking that way, the simple things are always missed.
Suction leak at fitting coming thru firewall.
Respect to the old man double clutching like a boss
That engine sounds so good
#3 for sure, but #2 sounded weak too.
Aside from a cracked fitting or pickup tube allowing air into the system, the only thing left in the chain left unaddressed for fuel starvation is the mechanical pump itself. It might be too worn to maintain constant pressure, thus causing the system to lose it's prime over longer run cycles.....would be great to monitor inlet and outlet pressures over a run cycle.
AHH the good old daze :0 reminds me of my second career bus mechanic after 20 in the usaf working aircraft THANKS PEACE
You seem to be getting the hang of this stuff now 😀.
Man I loved the sound when he opened her up
If it has all new lines. As well as a new line from the tank. The only thing that is left would be the take up line in the tank.
Great Bus!
I think the pickup tube in the fuel tank has a rust hole from sitting and needs to be replaced. Friend's 4104 conversion started running out of fuel once it got below 1/2 a tank. Once he decided to pull and replace it the engine purred like a kitten. After the replacement he was able to pull the fuel level down to the bottom of the gauge and still it ran fine.
After he saw your video of replacing two fuel filters with one he bought and installed the clear one with and electric pump for priming the fuel system. Simply carries a couple of extra fuel filter kits with him.
We found the suction leak in a fitting where the fuel line passes thru the firewall.
All I can say is that this Video is great!!!
The hits just keep coming
Nice, Nice and beauteful design! i like very mutch!
Wow very loud bus nice job
24:00 There was no charging problem. The heater fan switch was on and I know one of the two motors is stuck, drawing excessive current. I don't know why the hell neither of us noticed the one fan running, it's obvious in the video. I knew this because I went thru this last year when I thought something was wrong with the charging system, and then I forgot. I am disconnecting the fan switch until I can get to the problem.
I would get rid of the old fuel (or use it for something else) and Pop in new injectors.
i had a prob with old diesel smelling like varnish, the fuel was super thin and didnt run right at all. swapped it out and run fine after that.
37:17 "This was filled with fuel, this was not" pointing to the filter on either side of the pump.
Replace the fuel pump.
Then check the supply line coming from the tank. You could leak-test it by disconnecting it from the tank, plugging one end, then doing a leak-down test from about 50 psi...
The Gm Greyhound Bus you are working on , i have to say I really love that bus. I would like to know are there many of those buses available? Beautiful Bus. I would like to own one like that one...
Phil's hair looks like the Dr. that was in back to the future with Marty.....lol
