That is the best looking cleanest GM 671 I've ever seen.....looks like he put a lot of effort into paint and polish on this....props to the owner for that !!!
The sound of a first start of a rebuilt engine is one of the most satisfying things to a gear head….especially a previously worn-out engine that barely made enough power to pull a greased string from a cat’s behind! That 6-71 certainly matches the exterior appearance of this bus….particularly fond of the exterior detailing of the engine.
That 6-71 revving took me back to my teenage days back in the 1970s Puerto Rico, When the island transit authority had Flxible and GM fishbowl buses using these same 6-71 as engines. Great to hear it run and let my mind wander back to those days of my youth.
@@BusGreaseMonkey New York City had *one* T8H5307A fishbowl with the 8v71, S/N 1166, but it was owned by, and painted for, the transit police department, not the regular NYCTA. Figures they'd have wanted the bigger engine. All the other transits were six cylinder powered.
Hey Scott, what a sweet sound coming from that motor! I ran an 8v 92 in a truck and trailer for 250,000 miles. Every day I drove it like I stole it.. magnificent sound at 2300 rpm. Every time you fire up a Detroit it takes me back to that time in my life. Thanks for taking the time to video for us !
Nothing like pouring the coal to a Detroit going through the hole in the wall. My exhaust pipe became disconnected before the muffler and I liked running that way. Yes, you need to keep them wound up and not lug them like the four strokes.
Scott, another transformation from dog to tiger! No smoke even when the rings have barely seated! You always build back better! Thanks for the job you do!
I thoroughly enjoy the sound of the old GM diesels revving up like that. Seems just like yesterday when I was young kid and seeing, smelling, and hearing them in regular service.
Love watching you fine tune this. We had 671s on a boat years ago and the governor was not set right so shifting was a pain. The old Detroit guy got in there and made it perfect. Great series on this rebuild
There's some love gone into that. It's a showpiece engine. However, I see a stud and nut missing from that two stud flange on the governer - or whatever it is.
Another great job! I do miss watching you do a test drive into town. It's always nice to see the buses going through the paces after your excellent work.
So as I'm watching, I see Scott is only wearing a Tee-Shirt, the other guy is dressed for Alaska. I tell myself, must be from Florida. Then I see the bus license plate, Alabama. I was right. Those southern people, if the temperature is below 70 degree's their freezing to death. Funny as all get out. Thanks for sharing Scott. That engine sounds awesome for a first startup. From the video, that bus seemed to have way more kiddy-up, just on flat ground, pulling away from the shop. To one and all do have a Happy Thanksgiving, God bless.
Something is definitely wrong with me… I spend my UA-cam time between here, air cooled VW rescue/restoration channels, and steam locomotive videos. All have their individual and distinctive sound tracks, but you tuning a glorious Detroit sounds the best! Oh, to hear it start its scream (with the turbo spooling up) as it left the shop! Can’t wait to see the hill climb! Hope your Thanksgiving was great!!!
I only ran across Scott and the channel two or three months ago, and by now I have the illusion that I have intimate knowledge of buses and Detroit Diesel engines! It is interesting how much you can learn by watching these videos. I love it when I can diagnose a problem before Scott describes what's going on because I have learned so much from him already. Bear in mid that I have never worked on a bus or a diesel engine in my life. I just love any kind of straight six engine, but these 2-stroke diesels are just brilliantly designed and so perfectly suited to their application. Just beautiful machines. UA-cam is a very strange experience when you can watch someone else's video of some guys trying to start a Detroit Diesel in an old tractor trailer, and here I am sitting in my recliner never have touched one but knowing why their engine won't start because I've been schooled by the Bus Grease Monkey!
Go back 3 or 4 years in the episodes. Back before Scott came off of the road and began building the hill top complex. He and the wife traveled the country making dilapidated 2 stroke Detroit motors run right. In and out of frame overhauls and removing heads was a daily event. You'll learn Detroit's from top to bottom watching them.
So clean! What a sound! I know the feeling and the tension when a rebuild engine comes to life once again! Great job! Looking forward to seeing the hill climb 🎉
Random tip for diesel guys of all kinds: prefill your fuel filter(s) with Seafoam when changing ( should eliminate need to bleed), it'll help keep injectors clean and engine will run fine on it ;) (as per Seafoam recommendations & does NOT void any warranties!)
On older engines, you should add some oil. The old fuel pumps and injectors used fuel that had more lube . Thanks to our EPA, oil refineries were required to remove most all lubricants. That resulted in many fuel pumps and injectors needing to be replaced much too soon. Seafoam may be OK for new engines, but older engines might suffer from getting the lube removed by Seafoam. Just my opinion.
god I still remember when you got the head rebuilt, then found that multivalve head, then when you added propane, feels like yesterday! missed you driving Lenny around the country
You make great content. It’s amazing to see an old GMC with a Detroit Diesel restored like you do. Now for the hillclimb of glory after the hillclimb of shame.
He s going to have put a wooden block under the foot pedal to keep from doing burnouts after he gets all that newfound power, right. Great job. Engine looks amazing in her dress up clothes, Bill
Scott, you know I'm just waiting to see the hill climb. I know how muck better it will do I just can't wait. As a matter of a fact I was the first to ask if that was going to be one of its tests. Keep up the good work love seeing your content.
What horsepower is it set up for? We used to have a few 671’s in dump trucks. Not big horsepower but would run against the governor all day long without any complaints. Sure sounds good. Y’all did a good job on that one.
That is the best looking cleanest GM 671 I've ever seen.....looks like he put a lot of effort into paint and polish on this....props to the owner for that !!!
Exactly my sentiments! 😊❤
you could rest your sandwich on it while you were working
Scott, the mechanic, is the owner. This is Lenny, his bus. 😊
It was a little forgotten while they were fixing buses for everyone else.
And that polished blower cover is really killer.
And another cool old stubbie saved!😊. Is awesome to listen to a Detroit run precisely after years of use 🎉❤😊
That painter has written his resume with that engine compartment. A true craftsman. Just like you Scott. Thank you.

First start sounded sweet. Well done, Scott, Jonathon and Oz.
The sound of a good running Detroit diesel sent me back in time 50 years! I feel young again!
One of my favorite automotive sounds. Detroit running after Scott’s magic brings them back to life.
Ah the glorious sound of a 2 stroke detroit
I can’t wait to see the hill climb!!!
The engine looks fantastic now!
Air B&B with a different view, EVERY MORNING !!! Love it !!!!!!
Nothing sounds better than a Detroit. Could listen to that sound all day.
That 6-71 revving took me back to my teenage days back in the 1970s Puerto Rico, When the island transit authority had Flxible and GM fishbowl buses using these same 6-71 as engines. Great to hear it run and let my mind wander back to those days of my youth.
Pretty sure the fishbowls used 6V71s, not the straight sixes. The older 6-71 has a slightly smoother sound to it.
Old looks used inline 6-71 and new looks had 6v71 probably a few new looks had 8v71’s but i don’t think i have ever worked on a 8v in a fish before.
@@BusGreaseMonkey i know it was a 6 or 6V cause it sounded a lot like yours.

@@BusGreaseMonkey was this a total engine overhaul on this 671?

Oz definitely has the attention to detail down pat, what a beautiful engine. His whole bus is gorgeous.
Kudos ! Zero smoke ,true testament to Scott and the crew on this great rebuild,,,!!!!!!!

Music to my ears. Great build.
There's some love gone into that. It's a showpiece engine. However, I see a stud and nut missing from that two stud flange on the governer - or whatever it is.
The stud was stripped we removed it and a new one will go in. I was not going to not start it because of that.
@@BusGreaseMonkey I'm sure you will. It all looks and sounds as good or better than new. Geat job.
Sounds a lot better than when it showed up; great channel, thanks.
I never get tired of any 2 stroke Detroits
Best looking engine compartment on a 4104 I've ever seen! Matter of fact, it the best looking 4104 bus I've seen in a long time!
Another great job! I do miss watching you do a test drive into town. It's always nice to see the buses going through the paces after your excellent work.
Thank you from all the bus lovers of America!!!!!

@@johngaither9263 Yes, John, I've been plowing through those old ones. Enjoying this very much and wishing I had engines like that in my road cars!
Love that engine looks the goods (I realize in only a short term appearance )
Bravo !! Hearing that baby start up for the 1st time was music....Can't wait for the hill climb...
I know more about "screaming Jimmies" than ever , even tho I installed 100s of jugs and pistons with crankshaft work. Heads
Sure wish I could afford an old bus , they're so cool and the sound those ol' Detroit's make is music , nothing like a straight piped Detroit
So clean! What a sound! I know the feeling and the tension when a rebuild engine comes to life once again! Great job! Looking forward to seeing the hill climb 🎉
Parts came in. Great tuning.
This is so nice, not a whiff of smoke! I knew a Detroit can run clean! What a lovely engine. And pretty, too. GOOD JOB.
Must be so satisfying to see all your work and expertise culminating in a great result Bravo
That engine sounds amazing.
That sound never gets old ..! Two stroke heaven .. got to love the Detroit Diesel chorus 🤗🙏
The 6-71 not only sounds great, but also looks amassing. Attention to detail.👍👍👍👍
If the interior of that motor is as clean as the exterior, that's one good looking motor.
It is appropriate that the auto generated closed captions say “applause “ while it’s running.
wow shes stunning . not one puff of smoke from the rebuild , great work guys :)
Какой звук выхлопа... Мощь и силища!!!
Scot and Kelly may you have a happy Thanksgiving! ❤
So NICE when that first start after heavy engine work sounds so normal!! Cheers!!

Love your channel and lenny strokers will never die that sound sam in devon england
That engine really shines and sounds excellent 😊👍 Great video 😊👍
Sounds great. The inline Detroits are fantastic ! Has to be one of the nicest bus engine compartments ever. Great work,,,Rock on,,,,,Izzy Strong,,,,
god I still remember when you got the head rebuilt, then found that multivalve head, then when you added propane, feels like yesterday! missed you driving Lenny around the country
This is Oz’s bus. Not Lenny.
Even on the very first start, it just sounded so amazingly smooth. Well done! And so pretty too!
That Detroit Diesel sounds awesome
Looking and sounding good 👍 guys
Nothing, I repeat NOTHING sounds as good as a Detroit/EMD diesel!!!
Sounds perfect! Gonna climb it now!!!
Great job, congrats
I just noticed a bus graveyard in Williams CA. There must a couple dozen of them, sitting on an industrial lot. You can see the lot from I-5.
Damn, that thing fired up right now. That was impressive. Nice job!
What a beautiful sound!
100% goals. What clean freshness
That engine is pure music.
Sounds so good
Has to be so satisfying the engine looking good and sounding great 🙌
Nice job, Scott. That first fire-up sounded like a fine Swiss watch.
Great Job Guys
That's NICE 👌 REAL NICE ☮️✌️
What a beautiful sound
It seems like you and Oz have become very good friends. You and him make a good team.
You make great content. It’s amazing to see an old GMC with a Detroit Diesel restored like you do. Now for the hillclimb of glory after the hillclimb of shame.
Sounds like a strong beast now
G'day,
That's a sweet looking engine and what a sound.
✌️ Peace
He s going to have put a wooden block under the foot pedal to keep from doing burnouts after he gets all that newfound power, right. Great job. Engine looks amazing in her dress up clothes, Bill
Sweet sound of success.
To me, the hill climb is the ultimate make it or break it test! I'm looking forward to that video!
Great sounding Detroit, started so easy! Clean air, clean oil it will last!
Looks and sounds great!
Just fantastic and a good end to all of your hard work that was put in !!
That motor is a work of art! Wow! Sounds amazing. 👍👍
Love that sound.
What a Nice sound❤
Beautiful! Sounds good to!
Dang, really moved out good there at the end! Can't wait for the hill climb!!!

Very nice! Well done! 👍 🙂
Sounds as good as it looks - SWEET 🙂
That detroit purring like a cat. Great to hear.
She sure is running great now. Nice work and happy Thanksgiving.
Looking good it sounded nice. Liked the way it took off down the drive way.
What a lovely sounding engine!
Wow, she cleaned up nice! Sounds great, Scott.
that first start is magnificent❗️
Wowwww..nice job guys looks very very nice.....happy turkey 🦃 day to all 👍

Engine sounds great. Bus color scheme is just right, not too much, not too little and the painted rims work well too.
