I hate the smell of modern “clean” diesel exhaust. Loved the smell of the exhaust from my old Mercedes OM617 and the old Ford L9000 that I learned to drive truck in.
well, fellas. I tried using the video for mood music on a dinner date. it triggered an emotional interlude that was astounding. yep, she got pissed off, threw her drink at me and left. Me? I was so horned out I played it back in super slo-mo and provided the happy ending myself. if you know what I mean.
With this I get some special memories of when I was in 7th grade and was in band. It happened during the "Monrovia Day Parade" while we were awaiting our time to march. This one Crown School Bus that was in service with Pico Rivera Unified School District went past us. It was a Detroit 6inline71 and yes it was straight piped. I felt so good when I heard the engine running like that, I just burst out laughing and at the same time wished that some of the Crown Buses that were in service with Arcadia Unified School District which had the same engine were straight piped. Oh boy did I feel good when I heard that.
I've rode a bus with a 8v71 with a loose manifold. I fell asleep to its loudness. Being a traverse setup I think the back seat crevice was where the loose manifold was. Music direct to my ear...
Just don't overheat it after you fix it hopefully. The 6-71 was the primary workhorse in it's history. One of the longest production engines in history
Awesome. Im wanting to do a 6V92TT swap in my truck. Just gotta figure out what trans to use. I do know I want a air starter just because they sound cool as shit.
Sounded like it was 4-stroking in certain parts of the video. Either that's how they normally sound and I just never paid attention or it could be due to said leakage issues with the cylinder head and blower seal. Sounds pretty decent though!
On the 71’s we’ve had and do have I’ve never had a head gasket failure, they seem to be pretty stout. Now the 92’s are a different story, we’ve had lots of issues with heads and liners and just generally coolant going where it shouldn’t.
A lot of 6v92s got rebuilt after a few years for MANY bus companies from what I heard was due to header issues... Weren't those headers the same ones from the 71 series?
@@ENYoriginal when you say header what do you mean: the exhaust manifolds, or the cylinder heads. Exhaust manifolds were the same basic design, yes. The heads were different when it came to clamping force and gasket surface area due to the 92’s greatly increased bore size over the 71 with the same bore spacing. This means less room between cylinders.
@@ENYoriginal I really can’t say 100% whether they failed “early” or not, the ones I’ve seen have issues were already 35 year old engines, some older than that, with high miles and god only knows how many hours. I’m not saying the 92’s were really bad, just that the 71’s were far better, excellent really as far as having great longevity with little major work compared to 92’s. One thing I’ve noticed, which I assume is due to the 92 being a “wet liner” design vs the 71 having dry sleeves (sleeves don’t have O-rings and don’t contact coolant anywhere) is that if you go to work on a series 71 after it’s been sitting for 5, 10 or even 15 years often times it will still be full of coolant, if not a tiny bit low. Every 92 that’s sat that same amount of time that I’ve ever seen is low on or out of water/coolant and usually has a lot of rust and junk in the rad, block and hoses.
@@J.R.in_WV my friend has a 1980 Grumman 870 transit bus that was original to New York City Transit and it was sold off after 4 years to a small company in Bayonne NJ. The original engine apparently never was taken off the cradle for a overhaul. 6v71. Only thing wrong is that it does run hot (2 o clock position) and the alternator acts funny...
Too much blue to be head gasket. That's a lot of lube oil getting into the cylinders and you're not gonna have that with a HG; gonna be the blower gasket instead.
Think aboot it. I could say, when queried of what i do, "this guys stuff and stuff." And they would say "you do this guys stuff?" And id say "and stuff". Then, when the say "I am confused." Then I could say "what?" I would get to have the same exact conversation with different pee-oples, all day, long. Just like this hillyou go up, its fun only if it takes all day. 😂 😂🤪😳
@@Youmommacallsme it's possible, depends on if the smoke persists even it it is completely warmed up. This 6-71 may needs some rings soon. But that mass amount of smoke at first start is from the oil pooling around that blower (kinda). It burns it off after 30 minuets or so. You can also smell the difference between coolant smoke and oil smoke too.
What a great sound, we need more trucks like this on the road.
You know it's an awesome Detroit video when you can smell the cold-start diesel exhaust through your screen.
No more acid for you🤣

2:12 that sweet morning mist... (or put another way, no mosquito troubles round these parts) :D
Skeeter deleter LOL
Nothing like hearing and smelling a Detroit. Diesel exhaust smells much different than the others
The echo driving that thing through the residential area was insane! Probably the loudest thing those folks have heard in a while lol

The sound was actually starting to make me fall asleep
My God Those 2-Stroke Detroit’s Are Loud. Can You Imagine A 12V71 With This Exhaust???
Yes, and I lost my hearing because of it.
What was that in? We ran a straight pipe 6-71 in our boat for a long time she was loud. I actually was sick of it all the time but now i miss it.
man do I LOVE that truck !!! and the sound !!! bad ass

damn! that sound is the best
Nothing says good morning America like a screaming Detroit Diesel
Excellent! If it dosn’t make noise & smoke, it’s no good.
I've got to say there's nothing like a good old Detroit fog LOL
That straight-six Detroit sounds beautiful
I'd pay to see an in cab or tailgate style gopro shot of this monster!
No wonder why the older generation deaf af 😂🤣
The horn is so funny!!
I bet that smells amazing man I love the smell of diesel smoke
Haha great stuff love the sound of a Detroit
Did I tell you how much I love this truck?
I still love this truck. Maybe more now. Took that damn muppler off.
Great truck.
that things a beast

oh yeah it never overheats, if fact it has trouble warming up. So it needs new thermostats.
@@ThisGuysStuffandStuff what year is this truck and what's the make and model of it?
@@dustinlanphear422 It is a 1976 Ford L9000, with a 6-71 Detroit Diesel
Awesome to see a new upload mate! And what a truck!

All the townspeople: "Not that flipping black truck again!" 😂

Dear Santa...
6-71 doesn't have one piece head gasket but love the for and power train
Have I said how much I dig this truck?

Yeah the blower seal is a problem on this truck, hence all the blue smoke on start up.
Cheech!! Love the sound of that beast!

glazed up to hell i deal with theses alot in buses
badass
If I download this video, can i put it on loop and just let it run?
Well, 5:09 is where that quivering begins to travel uppards from my toes. Damn! That's goo.
About time I see another video of that smokey L9000! Any progress on the 6.9?
yes actually, will be a video with in a few weeks. getting it put together now
I got it! We canraise the intake on the aircleaner. Maybe 8or9 more feet.
is it me, or do these sound like a straight pipe 4.3 with a mild cam when cold?
...just you??? I don't know what that sounds like
I guess I've never heard one
I'm telling you, you should bring in an expert. Someone truly spectacular stikn-n-stabbin a 2stroke. Pick me, pick me, pickme!!!!!!!!!!!
It doesn't have a head gasket
Homina homina homina!!!!
ment love the ford and power train
But still love the sound
is this in central oregon
Washington?
Run an 8' pipe to the rear bumper😁
What kind of truck is that?
It is a Ford L 9000, 1976. Motor is a Detroit Diesel 6-71, and it has a 16 speed twin transmission Spicer
Think aboot it. I could say, when queried of what i do, "this guys stuff and stuff." And they would say "you do this guys stuff?" And id say "and stuff". Then, when the say "I am confused." Then I could say "what?"

Good morning fellas.
Must of reached 140 dB and be heard 10+miles away.
They don’t have head gaskets they have oil rings
true! sometimes the word headgasket just slips out
Build more please
is it a v8
Nope it is a 6-71.
This means it is a
6 = 6 cylinder
- = Inline
71 = 71 cubic inches per cylinder
Try calling Delta Boy. He can tell you.
Blowing white smoke that can't be right
it's blue and white, the blower seal is failing
@@ThisGuysStuffandStuff i have the same problem on my 8v 71 you think its just the blower?

@@ThisGuysStuffandStuff i don't smell any coolent at all. But blow by is crazy. Im hoping I don't have to rebuild the whole motor
@@Youmommacallsme does the smoke go away after it gets moving and warms up?
Nice pollution machine, although sounds beautiful.
Technically
Homina homina
Um over rev it much???? Jeesh, no wonder why she's belching..
Its a 2 stroke its supposed to sound like that
12 ecologists gav thumb down
Detroit diesels sound horrible by today's standards ijs...
You're right! Mazda MX-7 / 8 sounds better!
everyone can have their own opinion, i much prefer this sound to anything modern, But that's just me
@@ThisGuysStuffandStuff I agree. I don't really care for cars. Mainly older diesels. Pretty hard to beat the sweet sound of a n/a 6-71
