Mechanic Gold!
Reminds me of the old joke "Guy comes into the shop with his engine running rough. Mechanic walks up and turns a screw, it smooths out instantly. Then he turns to the guy and says '$50'. The guy is incensed, '$50 dollars for turning one screw!'. Mechanic replies, 'No, that's free. The $50 is for knowing WHICH screw to turn'".
Absolutely BRILLIANT!
Thanks for sharing!!
It's about Value
That story about knowing charging for knowledge is older than the automobile. The earliest story I know of was with Charles Steinmetz identifying a fault at a power plant in the late 19th century.
👍
You got it.
A vacuum gauge is still a useful automotive diagnostic tool, even when troubleshooting modern vehicles.
Yep, but too bad cannot connect it into windshield wiper hose fitting anymore ;)
@@TheSimoc 😂😂
I'm buying the '52 Chevy that my grandfather bought new. If I remember correctly, the vacuum wipers stop when you go up a hill.
amen brother !!!
That's right because no matter what no computer knows how to give you real time ,unless it's a clock , but,,, seriously it takes an actual Guage w/ pressure and vacuum ,something you have to do separately .
Clearly, the vacuum/pressure gauge was the scan tool of the era. Really enjoyed this.
And in 2023 it's still one of the most important and usefull tool for the gasoline combustion engines!!!
Yup ! Still need a vacuum guage to set hi and low jets on a carb. You also use them to set your pre-load on the waste gate actuator on a turbo, in a round about way.
1942; “how to fix complex mechanisms that are broken or damaged.”
2022; “WARNING: DO NOT DRINK AUTOMOTIVE COOLANT OR BATTERY ACID!”
that just means people after '42 drank coolant and acid so often that the idea of labelling those warnings onto cars evolved into a "there's no way around labelling those to the cars"
At one time in the history of internal combustion engines, before glycol based coolants were created, alcohol/water mix was your antifreeze. Trouble was that the boiling point of alcohol is way lower than water and created inherent problems as you can imagine. I'm sure it was wood (methanol) alcohol that was used and that could kill you, thus the warning.
Engines were very serviceable back then. Today you cant even see the ground under an engine.
They HAD TO BE serviceable, servicing was required so often! Ah, the good old days.
Had a Freightliner come into the shop once where the engine would completely shut down on occasion while driving, then after a short rest would run as normal. Took 3 trips back and forth to the shop before I finally found out what the problem was. Some IDIOT had thrown his cigarette pack wrapper in the fuel tank. Probably too lazy to walk the 3 feet to a garbage can.
Every time the wrapper would float into the suction of the fuel tank outlet, it'd drop the engine off like a stone. Then with suction gone it'd go back to floating around in the diesel. We finally figured it out when on a 'hunch' we drained the entire 120-gallon tank and sure enough, one wrapper... Marlboro.
a camel man would never
Oo, man. That sounds like a prank!
O god, that is something you are unlikly to find easily. Sounds more like sabotage to me
I had something like that too. I bought Maserati 4.24. when testdriving in the neighbourhood it drove okay. I bought the car. On the way home the car would not go beyond 80km/h. Are the turbo's broken? The next day i took it to a Alfa and Maserati garage. They cleaned all the fuel tubes and injectors and changed the fuel filter. Your car is now okay. 25 km further it stopped totally. The garage dude came and towed me back. He gave me an other car ti get home. The days later: a call. We found the problem: i showed up and the showed me what they found. They left it on the ground: al kind of dirt and salt. A lot. They changed out the gasoline tank for free and now it drives as it should be. Indeed can the gas cap be opened by anyone from the outside with a screwdriver. So, someone did that in the car when it was still from the previous owner. I have a foto from the found salt. Regards from the Netherlands
@@gerhard6105 у меня были похожие проблемы с машиной. Купил фургон у мужчины, у которого как оказалось, были проблемы в бизнесе и со своими работниками. Кто то ему насыпал сахар в бензобак. Так же обнаружил, что машина не едет и не тянет. Всë проверил - всë работает, жужит и крутится. Снял бензобак - там сахар.
Пришлось мне промывать бензобак и все топливопроводы. После этого машина заработала как надо.
Man I remember adjusting points and valves … damn I’m old 😢
My Dad used to say
“It’s hell getting old, but it sure beats the alternative!”
Now I am saying it.
That was the most diagnosis I ever saw a vacuum gauge used for.
The previous scan tool. You had to know how to read it. I still use it for carbureted engines.
A perfect diagnosis method was explained very well , in the olden days....
Wow with ,
Key points to B noted is -
ignition,
compression &
carburation
Then the power was stabilized as per optimal need of the vehicle movement ...
Very informative vedio by them to re-gain the engine power ....
Back in '69, the "speed shop" where I had work done used a vacuum gauge to adjust "racing HYDRAULIC lifters" on a '68 Mustang that I was having "souped up".
Wasn't it lovely how basic and simple engine diagnosis and trouble shooting was back then. With just a small box of tools and the right knowledge you could solve any problem on any engine. The vac gauge was such a great indicator and easy to use like everything else. Those simple mechanical times are gone unfortunately and not for the better 😢
Who doesn't want to have a programming degree and OEM tools to do a 5 minute job? It's just modern engineering efficiency obviously!
Its actually easier now, the onboard computer using the sensors seamlessly performs all of adjustments shown in this video. If there are any issues, it will show you via a scan tool and the appropriate PID.
@@PremiumFuelOnly for those willing to spend several thousand euros every couple of years to upgrade the software.
@@MsRustynuts Nah, it's all free and out there. Just need to know where to look
Thats right without the modern trash and high costs...
Took me a lifetime to get good at this... All i had to do was watch a video that would have saved years of learning the hard way.
Aaaaaah the bliss of working on old motors.😊
I’m of the age cars and trucks operated just like this. To this day a vacuum gauge still works. Valves are valves. I ran a compression test yesterday on a 2016. I still keep a timing light and a dwell meter, but been a long time since I used them.
My truck is a points and carb engine cant fix perfection!
@@Victorsvolkswagens🙏🤠👍
Vacuum gauge the most powerful tool for engine mechanical testing
I loved my 1963 Ford Galaxie 500 it was such a simple engine to work on and understand.
Mine was a 65 Fairlane 500 Good Times !!
I had a 64 galaxy 500..I'd fill her up with oil and check the gas lol .sure miss it
When Ford was great!
It's a good thing it was SO SIMPLE to work on because those engines had to worked on ALL the time! Try to imagine that 352ci engine running with the SAME spark plugs for 100Kmiles, or not needing a valve job at 200Kmiles or not needing a COMPLETE overhaul at 60Kmiles, and on.......! There is a reason why the warranty was only good for 12mo/12000miles back then!
My father went thru this very mechanic’s course during WWII at Fort Leonard Wood, Joplin, Missouri.
Fort Leonard Wood is located near St. Roberts, MO about 150 miles NE of Joplin.
@@sarider6294 now maybe, have you checked to see if they moved location?
@@spazemfathemcazemmeleggymi272 I grew up 12 miles from FLW and my grandfather worked to build it during the depression. It hasn’t moved.
Ft. LostInTheWoods. I was stationed there
I trained there last year as a motor transport operator.
95% percent of these procedures are still used today on new automobiles. I love the relevancy.
i can't remember the last time I checked timing on a car I think it was a 72 oldsmobile. I remember when we all owned vacuum gages, compression testers, timing lights and dwell meters.
you still can use vacuum gages and compression testers
Left out "feeler gauges", grease guns and a "Sun Machine" (for you wealthier guys).
Not a lot changes,,same faults today as 80 years ago except no vacuum gauge, now a computer plugged under the dash board great film thank you
no software yet to tell me what the reason is why cil#4 is low on compression
@@lt.lasereyez8891 It was clearly covered in the film, nothing has changed : do a wet / dry compression test to discern the problem .
-Nate
@@VWNate1 hence my comment, this hasn't changed in a 100 years
I Learned how to be a mechanic from people of this era. I can diagnose engine noises most mechanics couldn’t. Or time and tune an engine without a timing light or vacuum gauge. It took wayyyy more talent and skill to be a good mechanic back in the day than ever today,
Cool
Back in the day, being a good mechanic meant understanding the "mechanical" operation of an engine. Today, you have to be an "electronic tech" in addition to being a mechanic!
My neighbor had a garage and one of the military Chevy 1.5 tons…used it as a tow truck, took many a ride i it and wow…it was on is 15th engine by then as it was a dump truck prior to it military service…later I had a 50 chevy 3100, basically the same engine, either the 216 or the 235….neat to find this video…..
I'm glad that fella was there to help out the operator. Gee, I wonder if he ever got it runnng right - and I mean right!
Just like my 45 Chevy PU. Or like my 46 Suburban or like my 46 3/4 ton flat bed. Love those old trucks.
This video is an absolute gem! I was surprised that they suggest checking the carby last. I find about 70% of low power situations are caused by the carb and usually it turns out to be bad fuel.
The cars they were training them to work on weren't old yet. The carbs were less than 5 years old nice and shiny :D
Carburetors are very reliable until they get old or sit a long time. Or somebody thinks they need a Holley double pumper instead of the stock carburetor
That might have meant that other stuff used to happen way more oftem, that nowadays is unlikly to happen.
Bolts getting lose is something you come across in documentation of the era suprisingly oftem. It was a big enough concern to use left handed threads on the left wheelnuts and other places for example, something that is unheard for many decades now.
@@crazy031089 Carby is always the very last thing to check, not the first .
Moist older engines will have tight valves followed by poor timing and you cannot possibly adjust the carby unless those are dead nuts first .
Surprised they showed a spark plug gap gauge but didn't mention it's proper usage .
Most older engines will run noticeably better if you run a slightly wider plug gap .
Contact points should be set using wire gauges .
-Nate
@@BlazingBlakesGaming Replacing a 4barrel that has vacuum "secondaries" with a double pumper does wonder for acceleration off the line. I ran Holley 4 barrel double pumpers in Boss 302 and Boss351 Mustangs instead of the stock set up, they were just as reliable! The only BAD thing was watching the gas gauge drop EVERYTIME you kicked in the secondaries!lol
reminds me of my 1965 rambler convertible. a very simple engine.
Boy, it's been a long time since I've used a vacuum gauge on an engine or adjusted points. Miss the simple times sometimes.
and I just DIY it last week....its great mechanical Engine Scanner
And some people used to do the tuning by the feel of engines running, and adjust the timing etc one of my uncle does that on old school engines back in my country as they still have alot off good old cars there from 70s 80s 90s so on.
Even if you changed points every other month?
@@stvargas69 if you set your gap correctly, changed or tested the condenser and kept dirt and moisture out of the distributor they would work as intended and be reliable. They'll never be as good as their electronic counterparts though.
@@PorkyHontas points are way better than the junk old Ford dura spark ignition! Tho GM HEI was the best.
This is my favorite video on TH-cam! I have one of those 1.5 ton G506 trucks, It has outstanding info for keeping her in Tip-Top shape!
There is a book called : G506 FULL MAITINECE GUIDE 1945
Look it up
in line 6 cylinder engines are bullet proof!
@@fidelcatsro6948 Stronger but not really bullet proof .
This engine didn't have pressurized rod bearings, good search "Target Lubrication" for some eye opening info .
They'll handle anything *except* high RPM's .
-Nate
@@VWNate1 🤔i see
That was a nice Era for diagnosis. They have changed so much. A lot of new engines with variable.valve timing don't produce enough vacuum to operate the brake booster safely. On the flip side we can monitor a huge amount of live engine data. I guess the key is understanding what your looking for. Thank you for this gem of a time capsule
I ENJOYED THIS FILM MORE THAN ANYTHING ON THE TUBE PERIOD!!! 😊❤
Nice Tripp down memory lane!! My father was in the 82nd airborne in ww2...reminded me of him..my dad won six bronze stars through out all the yrs he spent In ww2!!! I really enjoyed this❤peace✌️🇺🇸🇬🇧🇺🇦🙏
You praise men who fought Nazis in WW2 and then have a neo Nazi country's flag at the end of your comment?
@@spazemfathemcazemmeleggymi272 heah you say something about my father an ill tear off your face!!!🖕
Fukkn glory to 🇺🇦 🇺🇦 🇺🇦 🇺🇦 ukraine!!! How bout them challenger tanks an ammo they just got!! There's plenty more stuff on the way too..they will drive the communists out of their country!!! And we will help them!!! How bout that!!!🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🖕🖕
Even if some of these techniques and tools are outdated, the process and general operation still work very well. Don't fire the parts cannon at it, diagnose and work through all your possibilities before confirming. The same can be said for other scenarios outside of automotive, be sure and work through all your possibilities before coming to a conclusion. You'll be less likely to make a mistake that way.
Today seems the complete opposite. 'Annual service oil change' is an opportunity to 'find fault', point out a rusty brake disk or excuse to do unnecessary shoddy repair work that makes more problem s later on. And diagnosis is now the opposite, even with a scan tool they'll just replace whatever is unscrewable mentioned on the screen, instead of finding out what's wrong first they'll replace every single component one-by-one until the customer stops coming back.
This guy is the original south main auto. 😆
Cool video , do you think Eric O . Has seen it !
The best video on Vacuum testing, I have come across on youtube. Great Explanation....
Good stuff here, what I was taught 60 years ago .
This is the Chevrolet "Babbitt Pounder" engine, able to run nearly forever if you take proper care of it .
The intake manifold tightening sequence is dead wrong ~ you begin at the center and work outwards .
Failure to do so is why so many have cracked manifolds ~ it 'crawls' as the heat expands it .
Too bad so few care about how it works and how easy it is to make an old tired engine run well .
-Nate
Matchbook cover thickness works good for setting ign. point gap.
Running two 1944 Dodge T214 flatheads , this is pure gold!
This is the best “How-To” I’ve ever watched
I work on post war BMW motorcycles, and this was both a good reminder of basic skills as well as a great watch! thanks
I LOVE THESE TRAINING VIDEOS FROM LONG AGO! VERY EDUCATIONAL AND INTERESTING !❤
I've been assigned to work on a CCKW and the Chevy civilian equivalent. I stumbled across this video on my day off and it's just what I needed!
Several comments below refer to replacing ignition points. Anybody still have a point file and/or tube of special distributor cam grease?
I have both.
I still got one points file used to be $2 now they're 15
Yes of course .
points files are a special typ ~ they're "Burnishing" cut .
I've been saving Dwell / Tachometers and dynamic timing lights from trash piles for decades, I teach those who want to learn how to use them, very few old vehicle owners care until it doesn't start or stops suddenly .
My Metropolitan Nash Club has Tech Sessions to do and teach these things in the film .
-Nate
Old school, back to basics.
Now this was a great no BS video on how to work with old iron, which Im getting into at the moment with early 50s stuff. Spot on perfect for what I needed to know. Thumbs up!
Fuel, spark, compression. The details in between. Love these old videos. Kids today just want something plug and play.
BareRose Garage sent me here. Good knowledge shown here.
I miss working on old stuff!!
Complete with sprocket drag and skips, just like the original.
Imagine if anyone had to fix their car today. Many would be totally lost.
Not really! A cheap scan tool and SOME knowledge (thanks to YT) and you can fix a LOT of problems! Stop being so pessimistic!
I thought vacuum advance should be disabled to set base timing?
You’re actually right
@@wb3161 NO ~ there should be NO VACUUM SIGNAL AT IDLE .
-Nate
@@VWNate1 depends on how the setup is. Many have no vacuum at idle and receive after the throttle cracks but many have full vacuum below the throttle plate and will retard on acceleration and advance as load comes off engine as speed levels out. The idea is remove the vacuum line to be positive your seeing base timing. I’ve been working on cars as a career since 1981 and still doing it today in 2023
@@wb3161 Thank you Sir ! .
So far I've only run into the full vacuum at idle and bleeds off as you accelerate in older Mercedes 117 engines, kinda threw me for a loop but once I understood it I was able to power tune it .
I'm a retired Journeyman Mechanic began in the early 1960's I love learning, please keep sharing our knowledge .
-Nate
@@VWNate1 you are very welcome
Very informative, helpful in understanding.
I have all these diagnostic tools and still use them to keep my 1969 E-Type running sweet.
I miss the simple engines😢😂
I don't mind the computer stuff of these days car but the accessibility, just changing cabin filters or sparks is a damn pain these days, never mind where they put the damn airbag collision sensor. Colleague of mine said nowadays they design the car around the damn oil filter
Some.of heater cores on newer Gm you have to take front doors off, dash ,seats,steering column and tie bar. Then evacuate ac and remove hvac case. I do miss some older stuff. But pre old 2 or even old 1 can be challenging. I would have loved to see this video in the early nineties when I started. It would have been a cliff notes of pre fuel injection diagnosis.
@@theclickband1 the last carbs were a pain to diagnose eletricly steered soilenoids galore, I was glad when ecu controlled injection became the norm, that and obd standard, fuck im old
My father went to mechanic training in WWII. He said the instructor wanted them to get a 4 cylinder engine to run on 1 cylinder. I don't know if they were successful.
GREAT AUTO REPAIRS VIDS
It’s funny how we think we advanced so much but today we still use same tactics (like compression gauge) that are 40, 100 , 500, 1000 years old ..
This was cool 🔥
I have a couple of those old timing lights, thought they were no good, found out they need to be hooked in series, gonna have to try them again!
love those old videos
Hit pause at 0.40 who else sees the optical illusion of a guys head looking up in the background…once you see it….
good to know this stuff.
Narrated by Al Bielek...
A time when you could actually fix it on the side of the road.
If you had a Holley carb, you could adjust both front and rear "float levels" on the side of the road with just a common blade screwdriver and an open end wrench, WITHOUT removing the carburetor!
Awesome video
My Step Father was in the motor pool during the Battle of the Bulge. And now you know.
veryful information
Great video!!
Don't miss contact points. Replaced a gazillion
I keep a matchbook and a set of points in my old car just in case.
Or distributor caps either.
reminds me of my pesky 72' datsun 1200 ...once the mechanic replaced the points with a used electronic ignition module from Honda all my ignition problems went away!
That's one thing I'm glad I don't have to deal with anymore.
wow that's amazing test the part don't blame the part and change it today there are no mechanics there are Parts changers those who continue to work in this way are counted
My Grandfather was a mechanic in WW2 for the Army Air Corps. 1942-1944. I wonder if he had to watch this?
Such low compression engines you can hold the gauge by hand.
I still swear by older engines easy to fix you can't do much with modern engines from your own garage
The i.c.e is still amazing 🤘🙏🤠🔥💣
BUT, the future is ELECTRIFICATION!
@@TheOzthewiz AWESOME 🤠🤘
And dont forget to test the horn when someone is under the hood working
13:27 somebody tell the EPA this information. They call it an EGR.
Heatriser and egr are not the same actually
@@wb3161 he was making a joke about the cracked heat riser
😂
Did he just say exhaust gases in the intake ruins performance … 🤔
@1.35 money lamp was on so he grabbed his computer 😆
Wow back then they used vacuum power to run the windshield wipers!!
These tests are information still holds true today
A vacuum gauge and a PicoScope is all you need nowadays.
Larry Fine is a good mechsnic.
Why not just plug in the scan tool ? 🤤🤔
Yeah check the fuel mapping
Silly rabbit the obd2 won't work on 6v.
they havent invented transistors yet back then..
I guess a blocked cat would not have been the issue back then.
Awesome 👌 video.
Very rare you have low compression in a motor under 100k older motors it’s usually a bad carb now with the new fuel especially in boats and cars that sit
If they do sit make sure you run the carb dry or you will have issues later
Love the hats
Very good 👍
And if the distributor bearing is worn you never get a even idol its good to put a gallon of air plain fuel in it also replace the timing shain and always have a agm Battery
time stamp 13:28 and now they put EGR SYSTEMS on things... you can not buy quality anymore....
I would think ,[in combat conditions] the mechanism lokk for holes in engine.
This maybe "antiquated " but, the principles are the same......
Diagnostic evaluation has evolved to "put it on the computer" BUT the computer only tells you "what's not working" rather than why it's defaulting..... a good tech will use ALL MEANS at hand to completely diagnose....not just change sensors/parts......
Back when you could see inside the engine bay.
This knowledge will be golden after the next Carrington Event.
Too bad digital media will be inaccessible 😂
Vital information
This was an era where even if you weren't educated, people still had common sense.
We went from this to plugging into a computer. I now drive an electric car.. When it broke the instructions read turn it on and off five times. I did and it basically re booted the whole thing and I was on my way.
I like to use MMO for stuck valves
Back when they gave volatile information instead of useless knowledge
so timing looked to be set statically is that right? or with a light and the motor running but not shown for the cameras slow shutter speed?
Lol those good compression numbers are pretty wheezy...
Army vehicles needed maintenance every day !
