- *READ This is the first video with my new Samsung F40 Camcorder. My batteries are almost 4 years old, they are tired and my fuel is exceptionally old as well. I haven't added diesel in over 2 years now. I finally had to put some jumper cables on it. I think an 8V71 starts better. It was 26 F during the night during the vid it had warmed up a lil to around 50F. Keep in mind all the fluids/hidden metal are 30-40 F. I have another cold start vid from last year. This year, I had to grab my car to jump the bus off after the first attempt failed. I assume engine rotation speed by the starter affects start up. Even with additives, the diesel is just old. I put 67 gallons in I believe two years ago which filled it to the top, there's about 179 gallons, 95% usable I believe.

Oh, I hate to hear someone rev up a diesel so soon after starting, especially when it has sat for so long without being run.
exactly, it clearly abusing the engine, alot of people dont understand that, its very important to let it warm up for a long time during extreme cold weather. people should NEVER EVER rev a cold engine. otherwise they gonna quickly destroy the piston,piston ring(s).
Man, I want to own an entire bus! I wish I could be that cool!
One day you might. It's fun and I wish you luck. Word hard and save.
Party bus
Lord Sandwich agreed. I hope some day to make an RV out of a bus.
+Lord Sandwich they're big and require alot of space
+David Brailsford thats a cute profile pic :3
Congrats! I knew it was getting ready to start, when I saw the white smoke of unburned fuel. You did the right thing to crank and rest, crank and rest, to take advantage of whatever heat you were able to generate, but I would have given it squirt of "incentive" after the second failed attempt...but I've never been known to wait around! Speaking of waiting...your fuel obviously still burns, unlike the stuff we call gasoline these days. I believe I would go ahead and change the primary fuel filter though. When I bought my first bus to convert, we made it home, from Minnesota in December..about 800 miles in the dead of winter. But, when I went to service the beast I was amazed to find the primary fuel filter pretty well clogged with "jelly". BUT, through no fault of my own, it started pretty darn easy. It was an 8V53 Detroit.
Sounds nice and looks smoke free once it gets started!
cannot stop enjoying this old bus singing out the real song floor a Detroit!
That rev is pretty epic!! Sadly they replaced most of those engines with Detroit series 50s on most of these 1980s coach buses. But glad you kept that one!!
That ol girl is just like the city of Detroit itself, all worn out and wont start or run.
She did start & run.
I had a Wanderlodge RV (Steel Bus) with a DD Series 60. Big diesels do NOT like to start when they're really cold. Of course, engine condition plays a role -- but the _careful_ use of ether (starting fluid -- not too much) will get one going pretty quickly. Old diesel (in the tank) isn't as bad as old gasoline ... but there can be some degradation to the fuel over time. It's necessary to ensure that the tank is full during storage/non use to avoid a build up of water from condensation in the tank. The water will drop to the bottom of the tank -- my fuel tank had a special low spot for water to collect, and a petcock that allowed the water or otherwise "bad" fuel to be drained. The biggest danger is for algae to form in the fuel, it can quickly clog a fuel filter (there are 'anti algae' additives). Good luck with your bus.
Love it! Keep faith in old diesel engines.
I think it is fascinating that you own your own bus!
Nice ! Hey it's obvious you are into this sort of thing. I liked the closeups of the smoke drifting out of the pipe after it didn't start. I once watched a cold start of a similar age bus. It was struggling to fire off the cold diesel oil, just not quite fully able to run with the starter still engaged and helping, making a beautiful sweet smelling thick white raw diesel cloud and a big puddle of almost raw oil on the ground dripping out of the exhaust. Sooo Hot !!
I used to be Detroit certified, after a job change 3 years back I no longer have my DD G2, but I'm currently Cat, Cummins and Paccar certified. I thought I might state my credentials before making the following comments:
1) DD's can certainly start cold, but the throttle lever limited gov. travel, so no throttle = no revs
2) No DD in the heavy duty on highway class has been built with glow plugs.
3) EGR was introduced for the EPA '04 compliant engines. It would not effect a 1981 engine.
Great, this is one of the best coldstart videos I've seen.
I just Love this video I own a bus my self lol love a good cold start video.
No where did I rev it while it was cold, just raised the RPM's to keep in from stalling. Watch the vid it tells you it was warmed up before I started revving it. I put that there to keep the trolls at bay.
Starting fluid is your best friend!
Those poor batteries.
No think of the starter
Need this guy in the summer to help fog for mosquitos!!
And it's great that you got her going again
Memories light the corners of my mind.........
@Jobergg Glad you liked it. When its 60F it has no issue starting. There are many variables to starting, another thing this bus uses straight SAE 40 either Rotella or Delo. I probably haven't driven more than 500 miles on the oil, its been in there 3.5 years but it should probably be changed soon. The bus is currently parked and un-registered.
Awesome sound man!
batteries are knackered for a start!
Best diesel cold start ever.
Thumbs up
Are the passengers complaining yet?
WD-40 into the breather and crank. It's a lifesaver!
Dagon Naxos 🤣🤣🤣
Shister
@@thegeneral3094 What is a "shister?" Is that a portmanteau of "she" and "sister?"
Thanks, there will be more videos coming hope fully in the next few months. There will be an MC8 with an 8V71 in the show.
Cranking speed was fine during the first four minutes or so, just to dang cold. A trick I used with GM two strokes was to crank them while holding the fuel rack closed, this stops them drowning on their own fuel. Then while cranking slowly allow the rack to come in, giving it just enough fuel to light without 'flooding'. That way you get some heat from combustion to help. BTW, ether cold start aids were a factory fit option on these things -).
The only problem I seem to have with Cat engines (newer) is regaining fuel after losing prime (filter change, etc.,). We plug all the block heaters in on the Cats, and as long as the batteries are good, they seem to not mind temps. This is in quarry work.
People don't understand the dangerous chemicals involved in getting rid of those batteries. Things just mysteriously disappear into a portal of magic and green happiness.
Someone should show this guy what starter fluid for diesel looks like and where to spray it in the engine. I could have had that started in about two minutes. Did many, many years of ski trips in the mountains of Colorado, and would make sure I always had starter fluid with me. It never let me down!
Must have run buses you didnt own, or you would have known what that ether did to them motors.
Duckyistrippin you do understand that proper use of ether causes no damage in a direct injection diesel. the only diesel engines that you should never use ether on are IDI and those equipped with an inlet air heater. Theres a reason Cummins equips their generator units with an automatic ether injection system, and its not cause it damages the engine.
here in Maine when it gets 30 below zero we have to use ether because alot of diesels wont start so when your 100 miles in the woods a can hours away from any towns a can of ether comes in handy the only time i seen ether hurt a engine is when some one put a whole can in it and blew it up. a little sniff wont hurt it.
@studpuppy69 Damn, SAE 40 is real thick oil, can you use that oil durig winter or do you need to change to 15W40 etc?
Correct. It even states it was warmed up. Of course, you have to raise the throttle to keep from stalling and it keeps the oil pressure up.
SWEET ! .
I love these old Two-Smoke Detroit ' Road Oilers '.
City of Los Angeles still has quite a few here and there (City Hall,Piper Tech,L.A.P.D. Etc.) in service as backup generators , listening to them go down the open road at full chat is wonderful , don't hear that anymore though =8-( .

I carried 5 gallons of #30 oil with at all times. Before the rebuild the black smoke really rolled and oil leaked from every possible connection. After the rebuild the first leak took a year to show up. Also went from an A block to The B block for better water cooling. Had to also replace the cracked heads and worn cams, crank, and blower.
So, you still have it and it's running well ? .
-Nate
No. I had to sell it. Couldn't afford to keep it at that time.
Classic sound!!
Would certainly pay off to check the injectors. If they don't produce a fine mist then it will be harder for the engine to start.
don't know anything about diesels but is the smoke thats almost 'seeping out of hte exhaust at the start just residual or is there a reason behind it
I love the video
Hey thanks for posting if you look around on the intake system you will find a ball cup a brass cup with a piercing needle inside and a spring hinge top i takes either balls a small shot of starting fluid, It will do no more harm to the engine than your cold revs did, My best advice plug her in 2 hours prior and no problems cold starts are death on deitroits. If your in the midwest and need service ask for matt at interstate service Altoona Iowa. Again thanks for posting.
love watching this.
A little bit of ether would've had her on the go QUICK!
does this bus happen to be in denver nc?
Those Detroits are pain to start..Talk about good engines though. My Uncle had a Long nose Pete that had a 12V71 in it... Talk about a screamin truck
How much did motor coach industries cost to purchase? I ask because I would like to purchase one.
what means this white smoke from the engine when it not runing?
Starting fluid is not good for the engine. It causes the engine to become reliant on it and causes rapid internal wear. One trick I discovered, simply giving the engine a small amount of throttle when starting cold, the engine fires up quickly.
Nothing rides better than a MCI bus.
I’m not knocking the 6V92 but I preferred the 8V71.
DD 71s LOVE a little heat. Block heaters, even when it's not that cold out. Where I live, it will hit 40 F at night. I try to start my 8v71 once a week. No block heater and the motor will crank for a few seconds before it fires. Plug in a block heater over night and it's roaring to life before my finger tip even leaves the starter button! One quick touch, with a little heat.
Detroit diesel does offer an ether start kit, or just a slight whiff of ether into the air intake, half second shot or less. Even the slightest amount makes a big difference and a huge amount can do damage, sparingly is key
Oh by, I thought my ol girl started hard in the cold. One trick I learned was to hold the fuel shutoff lever down while cranking for 10 seconds. This warms the cylinders without dumping fuel, I find it kicks over better then. Of course even 30-60 minutes of block heater time works well too. Never either though, unless you like like an engine turning backwards on you or worse.
Do you use it for charter service or something?
Starting fluid does not cause the engine to become reliant on it for starting. It can cause internal wear and even destruction if not properly used. By personal experience, I have noticed that most people do not understand how to administer it into the intake. Ether should be sprayed only when the engine is being cranked over. If it is sprayed into the intake when the engine is not cranking, the ether will enter the first cylinder and cause an explosion only in that cylinder causing a bent rod.
Robert, very interesting explanation. Another mechanic told me that ether can damage the 'fire rings' (topmost rings?) which would basically reduce the compression and increase blowby. Any thoughts on this? This was on a DD 6v92.
Great start! Agree that the 8v 71 starts better. (if batteries are good) otherwise it's no different. And they sound better. Great vid though. Keep it up!
You speak about old fuel in your description and how it affects the starting.
Did you try yet with fresh fuel ?
i have a diesel with 3 years old fuel at least and it's not very good at starting....
it's supposed to last around 9 months or so.
agreed, particularly if they are smoking like this they are close to running. Little sniff of ether does it right away, no harm to the engine
Do you still have this bus? If so can you get a longer clip of the AC coolers running
The batteries are low, now they are completely shot. Do you think there is something wrong with the injectors? It's lost a little power on the top end. I could run 80 MPH at one point, now I'm lucky to run 75 MPH. I'm sure it needs some adjustment.
Same works for the NA 6.5(I think)liter GM V8 diesels in Humvees. I get one that doesn't want to start right away, give it some throttle and it fires up instantly.
@sledheadchris Thanks, I've added annotations and a description. I've started before in cold weather the batteries make all the difference it starts first try. The starter just can't spin fast enough. I suspect the old diesel doesn't help, I've put additives in it but it can only do so much.
Mount Cook Landline New Zealand had many of these...a great Coach besides the Alison Trans that would get a bit testy between certain gears on some hills
Mr.Grayhouse really got someone on this auction item
i have to say your the first one ive seen that didnt dump a whole can of starting fluid in the intake for a cold start or as soon as it cranked reviving it wide ass open those old detroits are very tempermental im gonna say good job regardless of the trolls that scream egr and glow plugs there are alot of people that need an education on the start up and operation of a diesel engine and before you trolls ask why i know so much 27+ yr exp/cert auto/lt truck and heavy diesel tech good job !!!
I remember this video from when I was young.
is there anyone can tell me why engine cannot start in winter as easy as in summer
Bleed the fuel system?
what year is that mci coach
Looks like my old MCI 8 w/an 8V71 starting up. Mine had even more smoke though, lol.
these engines have no glow plugs to pre-heat. but a webasto parking heater in water system to pre-heat the coolant would be a great help, would warm engine coolant and oil, give some heat to help start compression fire of diesel start. if used in cold weather often just a thought.
1981'mci Detroit bus...this one reminds me Flesh&Bone movie ..the bus station scene while Meg Ryan had rather smoking on bench for having a ride to Marfa TX specially at 7:00 I've throwback to scene when I heard this engine sound
excuse me sure you have some really nice looking buses i love the mci coaches made from 1981 to 1999 were did you purchase yours from im looking to by one
I love listening to that thing idle.
Is this the Atlantic City express bus?
Whats with all the white smoke is it becouse the fuel is old??
does this not have diesel glow plugs???
I do. Read the description, I don't need a rebuild. I learned after applying a little throttle it starts right up when cold.
the diesel gets all gloopy and solid like goo
Do you have cat diesel? If so i would like to see a cold start.
id love to drive that damn bus i love it!!!!!
would it help to pump the gas on that?
I think you'd probably benefit from a block heater. A big one.
Is that engine the same used in the M113 APC ?? It sounds like the APC one... and has the same colour!!!
I like this smoke
I like to inhale the smoke 👍😋
are you converting it or are you chartering it out
Do you have to have a CDL when you own your own bus?
It varies on the condition of the engine and if it has prime for the two strokes. Applying throttle on the 6V92T helps during starting. The 8v71 seems to fire in the first rotation in a split second. The Series 60 stumbles a little when cold but starts fine. Not sure what Detroits you work on? The L10, M11 and NTC seem to have trouble firing when cold or losing prime. Also, MUI 2 stroke vs. DDEC 2 strokes effects it too. DDEC starts easier I believe.
Which engine, an 8V71 or a 6V92?
its probly just a simple problem with either the compression or bad glow plug designs, motors do like to be hot hehe what you think?
Victory at last. I always find myself smiling whenever I hear a DD 2 stroke start and run. It gives you a little holiday during your working day.
Mechanical parts do not become reliant on starter fluids but for sure it can destroy diesel engines because of the pre-ignition effect of the fluid wich is very easy to ignite.
those fluids are for gas engines with half of compression ratio.
I like that sound engine
What are you listing to ? sounds fine
That motor would make an awesome swap for somebody!
these things must be clapped out. my 8v starts like a dream.
should have tried to plug up the block heater if it has one but a shot of starting fluid would make her start I do not recommend starting fluid but it does work.
This kinda like the morning start in my 4WD lol
My bad. Let's agree we both live in tough weather counties. Keep you feet warm and so long
always been a fan of a hair dryer in the intake
you can really hear the batteries/starter starting to die as he keeps trying to start it.
Hello studpuppy do you still have your 9?
