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
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...
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!
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.
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. 😂 😂🤪😳
@@crazytrucker2376 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.
