- 1st start of my detroit diesel 671 after the install of the new 4 valve head. Also installed a davco fuel 382 fuel filter. And getting the tires loaded up for the tire shop to install them tomorrow morning at 8am
$147 including tax for all those hoses.
I would get AN (and other) reusable fittings from summit racing and hose. Build my own, like I have done for rods and race cars way back. Keeping some hose and a few common fittings with me, just in case. So I can make a hose on the road. Cheaper? Not really, but flexible.
Great price, where did you buy them?
Great price on the hoses. While on the road in rural areas Napa maybe the only game in town.
Why is there 3 rocker arms per cylinder? And 4 valves?
Outside two open 2 valves each. Center one fires the fuel injector
The sound of that motor at a balanced idle sends shivers down my spine, especially with no hunting, hope I'm not alone with this, Scott, you're the tops!
I was a Detroit diesel mechanic for about 20 years beginning in ‘74 and 6-71’s were my favorite. Easy to tune and set the rack to the governor. Great engine.
‘“Oh, yeah, i’ll just redo my entire fuel system after replacing my head, might as well.”
Respect.
Hands down, one of the best video sites on TH-cam.
Interesting and informative, I look forward to every one!
I love the melodic rocker arm sounds and movements of your engine. It's impressive to see the mechanics of it work without the valve cover being on.
Diesel knock is a really soothing sound.
That motor sure sound goooood, purs like a cat... Must of been put together by hand tools... Nothing like the fine touch of a machanic hands... Good job father and son!
I second that.
I can barely keep my oil changed in my cars & motorcycles-I love following Scott! When I see him hammer on a monster clutch, new head, etc. Then I wait for his video showing it run.
Installing a primer pump is a pretty good idea. Back in my 2 stroke trucking days I put diesel in a pump up garden sprayer and attach the hose with a clamp.
Scott...You give me the incentive to get to the shop each day & do some wrenching! I'm currently working on Range Rover Classic and a turbodiesel Mercedes. I enjoy your "REAL" videos! Thanks for the inspiration!
Starting at approx 3:00, the most glorious engine idle sound. I could listen to it for hours.. I have my surround on and turned up the sub a little. I'm in heaven!
Sir, you are an artist fixing these beautiful diesel motors. I sure enjoy watching your videos, because how you explain in “layman’s terms” helps greatly for one to learn .
Thank You and God bless You and Your Business .
Great video as usual, don't see how you have the patience for that, Scott you Tyler are exceptional,and also the little lady behind the camera, keep up the good work.
The 671 is such a delightful mix of old-school physics and common sense. It might be a bitch sometimes but its simplicity and reliability are really hard to beat.
I'm a cat guy, always been. But when I heard the Detroit two stroke being tuned to an idle it was talking to me. May you have many miles of fun.
Having a 2-year degree in auto tech (1978) from a time when points and condensers where the norm gives me an appreciation of this mans archaeological (he digs them out from the ground) motortech.
I was hoping to learn who did the crappy work on that head. In any case, it did turn out to be a blessing in disguise. We all learned a lot from it and you got to meet some awesome people because of it.
To my untrained ear@4:33 sounds like that thing is idling absolutely perfect.
That sounds insanely smooth for an idling diesel. I love the two-stroke DDs.
Man I can watch this stuff all day! Glad to see I’m not the only one curious about these old buses and their engines!
Goodness that sound. Mmmm. Does something in the primal part of my brain that makes me feel like everything is ok.
Those 71 series run forever, best diesels ever made!
Not helping my plan to walk the dog! Enjoying this series
Walk the dog, this will still be here when you are done
Man I'm getting the fever for an old antique GM bus. I remember seeing the fugitive get off the bus the first of the program and get back on a bus and leave out at the end of the episode. I've always enjoyed the sound of the two-stroke diesels. Used to see quite a few of these pull in to fuel at the truck stops when I went to California and I'd have to go talk to the owner if I could. I really am glad I discovered your channel and really enjoy the videos. Man I've got the hots for one of these. 🇺🇸👍
I was the head hose maker at the Napa store that i used to work at back in the day, it was really something of a stress reliever for me. I once spent a whole day back in the hose room cleaning it up and organizing all of the fittings, it was a complete nightmare. After that? I got on people's cases for not putting things back after pulling them from the drawers and bin's.
Enjoy all your videos and buses are not even my thing. Would you consider adding an ending comment to each video instead of just an abrupt cut? Just a respectful suggestion. I love to see anything old and mechanical restored or repaired. Keep up the good work. doc
Sometimes i do. Tune in tomorrow for the next part ;) Long tiring day so you get to be continued.
Something just musical about the sound of a 2-stroke Detroit... I've been wanting to put a 6v53 in my Jeep... But the motor probably weighs as much as my Jeep!
Those cicadas in the background make me think of hot, humid, dog day afternoons.
My oldest Grandson was recently talking about cicadas and I had never heard that term. I thought it was Locust making that sound when the family visited Oklahoma in the summer.
I live near an Indian reservation on the west coast. A lot of the older fishing boats still run Jimmy engines. I've found both a 3-71 and a 4-71 at their garbage dump, a few years apart. I grabbed the blowers off both of em!
Awesome job Scott,sounds great. Can't wait to see the turbo installation.
One of the best Sounding startups of Lenny, that's Great Scott & Kelly
Sitting here listening to you set the idle on the engine made me realize that I need a white noise generator that sounds like a Detroit Diesel at idle. I’ll take 10% as royalties.
I like watching the valve "fingers" do their thing, its an interesting design.
Samuel Samsonian big EMD locomotives used basically the same design scaled way up. Think of instead of an 8v71 having a 16v710. That’s 11,360 cubic inches of 2-stroke GM diesel goodness. The turbo charged versions of those sound absolutely amazing. A rumble that will move your soul.
Rocker Arms, but valve fingers does have a nice ring to it. Rocker fingers is better IMO. Running full tilt they are certainly rockin.
@@Shane-Singleton , 2, 12v567 EMD. Were my baby's while in the Navy. LST-1150. On one tour (Vietnam) did not shut them off for 257 days.
Very interesting they use one rocker arm to operate a fuel injector for each cylinder. I think it's so innovative how injection timing ties right in with the cam timing like that on this engine.
When I worked for the railroad we used to shut the down once per month for maintenance. Since I retired the railroads both GE and EMD have gone from a 30 day maintenance schedule to 90 days and with computerized locomotives today when the locomotive is isolated on the control panel shut themselves down so long as air pressure and engine temperature are maintained to operating norms will restart themselves as necessary to maintain air and temperature.
Horsepower is from 1000 to 4500 horsepower. Bot GE and EMD do it the same.
This was a great series of videos, Scott. The bus sounds a lot throatier now with that 4 valve head installed.
Great video that brought back some memories, I know that drill all to well.
One step at a time. Scott, get some Super Clean, I find it at Napa, it's in a purple jug, squirt it on, wait 5, hose, the stuff is amazing, my blow by hose fell off, and before I found out, the whole underside had a liberal coating, Super Clean took it all off and about an hour.
Great video. The military uses them for years back in the WW2. days easy to train GIs so versatile to mount and interchangeable parts from 4 to 6 to871s thank you for your show how.
I am amazed with what you know about the old Detroit diesels and making then run.
Adjusting buffer screw. I"ve not seen that like since 1987 when i went to school and had to set the rack on a 3-53. Great video, THANKS. Cheers from Canada.
You know your way around your bus like I used to know my way around my Chevy...The new set-up is much cleaner, & you're helping the environment. And your wife can not only run the camera, but she can support the new filter base while you secure it. Truly fortune smiled upon you. #winning
Wow...easy start! Nothing like knowing what you're doing
Good Deal.. Looks like Lenny is almost ready for some New Adventures..
I can't wait see turbo and exaust 😁
There is that sweet music we've all been waiting for! Mighty nice job on the new fuel lines, too!
I like the tap on the back of the bus starter you have!
man, i dont have a clue what you are doing, but i watched the whole thing ! great vids!!
First Diesel Mechanic I ever saw wearing a diamond ring. :)
The decrepit hoses caught my eye and I didn’t have long to wait for you to take action
Ah, those are the taller 12R22.5 tires! Those should make the bus look really nice and run a lot better on the highway for those long open road trips. Cant wait for the test drive and your thoughts after its all done.
I'm worried that there will sap some power if he is already struggling on some hills
Taller tires will definitely make it long legged. But how much taller are they over an 11R22.5. Will they run at full lock on steering or suspension dump.
I don't like using gloves either. My hands will sweat enough to cause the sweat to run down my arms and somehow end up in my face. But they do a great job of keeping that grease out from underneath my fingernails, and the cuticles. I am very irritated by the grown in dirt under my nails etc. Several days excavating each nail with a good knife after a job is common.I find the old non-pumice style hand cleaner like stay lube was to be the overall best for breaking down that tough to get to grease and grime. Hat's off to your wife for doing such a good job with the camera.
Last Detroit 2 stroke I dealt with was a 6v92 Silver with ddec on it. Ran so nice.
only a pro can work up and old two stroke like you can excellent work
That is the exact filter I run on my Detroit. I think the new filter from napa ( in bulk package ) is 8 bucks. I love running it
Looked like you still have a leak at 19:15 in the video. Bottom curb side of filter dripped. I would also bend the positive alternator lead back away from the alternators case as it is very close and would cause big issues if it should touch.
I think it sounds a bit throatier! Nice work!
Thank you! That was really awesome! Congratulations!!
As much as you replace houses I would think you guys would buy the equipment to make them seems you do a lot of it I love watching your videos guys
You are a freaking Diesel guru! I love watching your videos!
That started up without any problems. 👍
I was just thinking what would the guys who built the engine think of it now. I dont think they would expect it to be still running and working so well.
I've been waiting for this
Thanks for the Great Channel. Your a Damn Good Detroit Mechanic. Had a Chevy PU with a 353 and Browning behind it. Couldn't wear it out.
Nicely done,Mr. C!!
Great job, I’m super happy for you and graduations.
2 ,3,4,671 series are some die hard motors.Dad had a671 ran it daily for over 20 years without rebuild.Yes it did white smoke until it warmed up worn fuel injectors worn sleeves.Come to find out the serial number on the block was 00000006 sixth engine out of production. ROBERT JOHNSON gave my Dad a rebuit engine for his old one which he put on display at his shop.
man, detroits are awesome
scott, looks like you have a great little helper there. Great video,stay safe !!!
Diesel motors in all there variance ARE the workhouse of the modern (current) world we all live in, if all these engines stop now just imagine what WILL happen , YES I know they are polluters ect but they are the only major mover would wide. time will come with better motive ideas ect & welcome them until then well still here & lov the diesil engine sound ( work horse of the would)
this weather right now is the best mechanic weather
Another little tip - ALWAYS plug the oil drain holes that are right beside the ends of the Injector rack - if you drop one of those little screws your day is going to hell - it will head right into the engine and it will have to be retrieved... also on those old machines that ur unsure of always change out the restricted fitting in end of the head on the fuel return side - if it is washed out u will have low fuel pressure and therefore low power... I'd run something like a gallon of marvel mystery oil per fuel tank to give the fuel some more lubriciticy... fuel has changed since those injectors were put in use...
I concur with your comments regarding veggie oil. I ran a car for a year on it, got through two sets of filters in 5k miles whilst using "normal" clean diesel they would last at least 15k miles. ( long runs not 5 mile trips)
Hi Steve ,you must pay special attention ,to the Air Compressor ,,Remember all those Air compressors Do pump engine Oil into the Brake System ,,also the fist Air compressors discharge hose ,
Have you ever had one start up while baring it over ,,,,I have had a ratchet on the front and it started ,,,also love it when they run backwards,,13 speeds in reverse one speed forward
can't correct my comment I'm so sleepy i drive at night but me and my nephew meet up in morning over bfast he lives with me 18....hes going to college diesel repair....i get home he's waking up...we eat breakfast watching grease monkeys vids 😁
"Want me to hold it?"
...
DAMN! Look at that rock!
Sounds deeper, lower pitch....power!
I can't believe how nervous you were at the 1:40 mark as you started the engine, you were shaking all over!
Also being new to your channel I would very much like a tour of your bus to see what you did and maybe get some ideas for a future build of my own thank you again.
Awsome with the new fuel lines and filter.
6:40 my bus actually has a vacuum gauge on the dash to tell you when the filter is plugged. It actually just said vacuum, took me a while to figure out what part of a diesel engine would pull a vacuum....
Engine sounds great. You got a ton done.
Those oil hose's and lines need some lovin
I always use a clear solo cup when draining fuel lines. Easier to get into tight spots, and I can see what kind of funk came out of each one.
Good job, now you gotta put it to work visiting clients...earn it's keep!
Cicadas in the background? Some noise every vid at you're place lol great channel more more I have learned heaps about GM 2 strokes not scared of them anymore great engine
Sorry traffic noise lol got it figured
I have learned a lot from your videos and I just enjoy watching you work. Please remove your ring when you are working on engines, hate to see someone else loose a finger to a direct short.
This reminds me...I've got a Racor R45 that I need to get hooked up in my ambulance. I've only been putting it off for like...forever.
My old 30 foot motor home had an electric fuel pump that pushed gasoline from the rear tank to the 454 engine up front. The engine had the old mechanical fuel pump. While on a family vacation, the engine started chugging so we limped it back home. The shop discovered a blown fuse on the electric fuel pump that was causing the engine to starve for fuel. Had I known about the minor fuse problem, we would have fixed it and continued our vacation. Live and learn.
those new hoses makes a big difference to the look of the engine bay
I would have thought you would have used a2 air & fuel line with aeroquip reusable ends.
Wow! That has a transfer case.
The installation of the filter with the new hoses looks great. And that electric aux fuel pump looks like an old Stewart Warner? They were noisy but super dependable.
Tell your fuel lines can be a pain in the butt. My motorhome had a CAT engine in it and it uses a mechanical fuel pump the problem was as it was all vacuum from the tank were no pressure l until the injector pump head. The fuel line was hard to find because it was designed to be rigid and not collapse under vacuum and it was very expensive when we finally found enough to do the entire motorhome
I'm buying five 175/80R13 tires for my trailer this week. I think all five take up the same room as one of your tires! =)
Consider getting a new clear filter housing? No clear fuel bowls allowed on an inboard boat engine per ABYC standard.
Why is that??
Wire up the fuel heater on the filter. you never know you might visit a cold state and the water separator I would wire in too.
Sounds nice, power lead on that alternator looked a bit loose.
Sorry, should have watched the whole video first, you tightened it ;-)
Nice progress on Lenny
sounded greate but looked at the end of it that you had fule dripping from the filter still.
Have you considered instead of running idiot lights to the dash (I know you said you weren’t) for the new fuel filter to just install idiot lights next to the fuel filter? I know you’ll have the engine running at times while at the back of the buss. That way occasionally you would see if you had any fuel system problems if the lights were on while servicing in the engine compartment.
Thank you camera lady:)
