100% it's always the engine. Replace the engine(all electronics and sensors too) and you'll be OK. Don't forget to add fuel.

Never argue with fools. I did find this video hilarious though!

Remember there are no dumb questions, only dumb people

The engine was not missing. I found it under the hood.😊

UK is still in Miles. I'm a electrical engineer, I use 2 yearly calibrated tourqe wrenches. As for PTFE, great way to destroy stuff, the amount of times I find liquid control valve failures, its always down to ptfe getting into the fluid. Glad I'm not the only one that has to deal with ID-10T failures.

Dirty Harry quote: "A man needs to know his limitations." I try to live by that.

What you don’t have a crystal ball? I am a mechanic in the marine industry and I have a lot of people ask questions just like that. My response is my crystal ball is a little foggy today.

Truck start only when someone sunshine weather rain only winter 4 cylinder fire are turbo on backwards run?

This needs to be a monthly segment. More ranty videos please 😂

If you really want to get mad about something, just keep in mind that the people leaving you these comments and emails will be voting this November.

I would like to rename this video! "Watch Josh get sucked down a rabbit hole kicking and screaming!" That's enough of reading the comments section today Josh. 😁 Enjoyed the video.

Crank no start, call mechanic ask him what to do. Starting fluid is a very last resort in my eyes, too much can do serious damage. Was always told use either once you’ll use every time after that. Besides it’s best to have it diagnosed by a good mechanic it could something totally silly like an o ring on your fuel separator. I guess the guy in the box truck decided you wanted too much information. Maybe he just decided to take it to a shop and get it fixed. Always good information in your videos

Dum is the new normal

I guess five people out of four leave bad comments. 🤣🤣

There’s loads of videos of people testing their abilities to torque up fasteners & get close to a specific torque just by “feel” & they’re usually wildly inaccurate. Human feel is no substitute for a torque wrench. Also, before the first torque wrench was invented they would use some form of spring measure on a bar of a specific length. Keep up the great work, I love the videos.

Josh that’s one awesome video👍👍👍 always remember one thing brother, the world is full of idiots. No you cannot tell bye feel what a torque setting is. That’s just stupid but there you go that’s what we got these days.👍👍👍

Do you speak Jibberish? I don't. Hard language to learn.

Running a plow truck in Northern Alberta we would consider -7 f as an average winter day. We ran in weather as cold as -30. We wouldn’t run in weather colder than that as you just break shit because steel becomes very brittle at those temperatures.

Those cats are really good engines ,too bad in our country komatsu took over the heavy duty materials,but this doesn't mean that KO is better than 🐈

Why is it called a torque wrench when it is literally a torque ratchet?

Blame the school system! Sad to say a lot of truck drivers maybe borderline illiterate. Doesn't mean they don't have great truck driving skills however, when it comes to constructing a complete sentence they're no better than good old Humpty Dumpty trump.

Torquing bolts prevents over stretching a bolt and rendering its clamping force useless.

Josh, we definitely want to know when you are frustrated. It’s good to get that stuff off your chest and it’s funny! Thank You!

14:03 time for that fella to put down the bottle.

Hey now buddy. I absolutely have a 55w light bulb with 2 wires for doing electrical work. Cheap reliable load tester.

Wow!, good job answering those as best as you could.

There isn't a single person in the world that can thump a tire and tell you the psi

I has truck with engine, truck no go vroom. Tell me why. These are the same people who can feel tire pressure and have torque elbows.

Another issue with Teflon tape on a drain pan plug is if the tape gets into oil pan it could potentially cause blockage in oil pickup tube screen or worse get into oil passages.

Can’t argue with idiots. We all know this. Lol

I tightened my fair share of bolts, and I can be within 10% at 35-150ft/lbs… but on critical bolts, I always use torque wrench.. why wouldn’t use it, so much easier to know for sure. Anyone that argues against it are idiots! Ah.. wrap enough Teflon around it, it will turn into a washer when you install it! 😂

Never rebuilt an engine, but this one really made me irritated. 3L EcoDiesel in a 2015 Ram 1500, had to do a water pump on it due to it leaking. Serpentine belt was also split in half all the way around. So got the water pump replaced and installed a new belt. Topped off the coolant and started the engine. Let it run to get up to operating temp. Went to wash my hands off and came back 5 minutes later and found it pouring engine oil on the floor, pressurized mind you. Had a senior technician look at it and he told me to take the intake manifold off. So did that, no damage to anything there and the oil inlet for the turbocharger wasn't damaged. So he took a dial indicator and his pry bar and checked the play in the crank at the Harmonic balancer...way over specification, and I'm not exaggerating when I say it was about 10 times out of specification. Since we didn't want to drop the oil pan, best guess we came up with wad that the thrust bearing in the crank was very worn out (vehicle had over 135k miles on it). So with a new belt installed and a out of spec thrust bearing, it wallard out the rear main seal and caused an oil leak. Not something you can always expect.

Darn none of my question made it. Will have to do better. Pulled the head off a 3406B, and on this repair. Someone put the Cat red glue on the cylinder block. Then they put the spacer plate gasket on. So then they put red glue on top of the spacer plate gasket and put the spacer plate on. As you can guess they put red glue on top of the spacer plate and put the head gasket on. Finally they put red glue on top of the head gasket and put the head on. So when I lifted the head off, stalactites was from the head to the top of the engine in several places. If I recall the head gasket was blown, but I never found out the reason for the failure. My boss told me he had a truck driver who came in complaining about green smoke out his exhaust pipe, years ago. He told him to stop taking green pills.

😂😂😂😂. So awesome funny. Makes you question where these wise guys came from. 😂😂

Love your videos man! I learn a lot from them. Torque wrenches were probably not that important back in the day because the clearances were not as tight as today's engines hence the oil thicknesses from them to what is used today.

I think you have some import questions. The command of the language is 👎👎 ! Some of your comments from you audience is a little ignorant for a mechanic. You keep doing what you do. I don’t know how you can put up with these silly people. Funny video indeed

Well if you can lift 75Lbs with one hand, and put that same effort at the end if a 1foot wrench, that would effectively be 75ftps?😅

I feel your pain! Best thing is to ignore those who think they know...but really don't!

The diesel and trucking industry has the most know it alls of any other industry on this planet. They get their information from channel 19.

Comments are mostly opinions and you know what is said about opinions

These people vote and I would assume most vote Democrat..

I do like using my incandescent test lights to make sure power and ground exists or if a light is actually getting power as needed. If the incandescent bulb is illuminated but not enough to be as bright as it needs to be, then that's when I pull out the digital multi-meter and start looking. I try to start simple before I start jumping into the rabbit holes.

Josh, you're too kind, Brother.😂 I wish you nothing but the best and thanks for helping those "special cases".👍

Yo, what do you think of bacon grease through the fuel system? Not a ton, just a bit. Project farm does a test running solely on bacon grease and it’s thought provoking.

I know a guy who can tell you about the current weather conditions are by sticking his head out of the door. Uncanny and remarkably accurate. The same guy can tell you whether it's daylight or dark using the same methodology. Experience, magic, divine gift???? There are forces at work in this world that most of us will never know of.

A great guy and great mechanic. Please!!!!! answer his questions with detail. He takes his time trying to help you and you give a one word replies. Luv your channel a sign of a good mech is that he knows that he doesn't know everything and is always learning. LOL I always use orange rtv and Teflon and JB weld on my drain plugs they never leak 5 out of 4 times. I always torque bolts by turning them until they pop or click than 1 more full rotation. 60% of the time it works every time. PS If you make shirts with a 5 out 4 times saying on it "I" would buy that :)

C4 is a military explosive😅

Hi Josh I am you sure you know! But for some people who don’t pipe threads are tapered the more you tighten the larger the diameter to make the seal ! Machine threads are the same diameter for the length! Teflon on the drain plug? Only makes makeshift gasket! Enjoy your video’s & humor. Cape Cod John

I've known an "injector" guy, black-smoking engine and it was the final air filter element installed backwards sealing off the intake. I had an engine that only started with ether, the #3 line headed for the nozzle was spraying a fast-pulsing stream of fuel out into oblivion out of a pinhole, perhaps they shouldn't be started if you find the side of the block caked in dirt and fuel.

I just loved the torque wrench story. Personally, I like to cheat, and measure things.

I had some guy on one of the third world country engine repair posts say that a torque wrench has ruined more engines than anything else. My reply? I guess that is why ever engine manufacturer uses one when they assemble the engine at the factory. You can't fix stupid.

Teflon tape: great for wrapping around brake pushrods to measure travel distance. Cold: I have people constantly ask me what the winter front is for and what it does. Torque: people obviously don’t understand bolt stretch and the consequences of stripped aluminum. My Question: how do you feel about gauges? What happened to gauges inside of trucks! My truck is 30 years old and has 22 gauges that each tell a different story and are all related to each other Ammeter running high, something’s draining the battery. Pyrometer high, too much fuel. Volt Meter, oil temp, water temp, ALL indicators of something wrong “BEFORE” $#?! Hits the fan. Where are the gauges and people that know how to read them?! BTW, my old W900 with a 3406B has to have a winter front for the oil temp to run 150 degrees. Without it, the engine runs way too cold. Love to see you mention a tray of coal under the oil pan before a cold start as well as a gasoline soaked rag instead of starting fluid.

You can anneal a copper washer if you have to. Get it to cherry red heat for maybe 30 seconds then quench it. Don't try and get aluminium cherry red though it will melt.

Back before torque wrenches and quite a while longer they didn't expect the engine to last the way we do these days. We also had to run them in with special oils for a thousand or so miles before applying full power. Things change.

Teflon isn't a sealant. It is a lubricant to help lessen the friction of the pipe as it tightens down on the taper. The taper is what seals the pipe.

I would torque wrench everything if I was building an engine. EVERYTHING! "Why?" Someone will ask. Because I am a human Gorilla. Everything would be too tight.

Sounds like mister -7 needs a winter front. I'd never trust myself to "hand-torque" a rotating assembly or valve group. I don't care if I've built dozens of 3400-family engines. I trust myself well enough on valve covers, front accessories, etc, but not on rods, mains, rockers, heads. Apparently ether-man has never heard of low compression. So far, those little funnels have been making a good showing. I'm liking it better than the layer of Aviation Seal on the plate gasket. Ummmm... very stylish safety shirt perhaps??

Hi Josh good day, I'm a fellow subscriber to your RU-vid channel. Thanks for sharing your knowledge, many of your videos have been very helpful. I have a question. I'm experiencing a loud squealing sound coming from the alternator drive belt. It is a Peterbilt with a Cat15 engine. I changed the belt and belt tensioner. The squealing sound didn't go away. I remove the AC belt to eliminate where the sound is which didn't change. I'm asking you for some assistance or direction to address this. Thanks in advance.

Good one Josh! A lot of us ol'timers have probably "lived" through half of these but eventually come to solutions. And NOW we all know why teflon tape seems to "leak" anyway lol! Cheers!

Robot Cantina literally just posted today a video in which he discovered that the thermostat for his little 3cyl Kubota engine would start opening at 160F and would go wide open at about 185F. Its fairly common for the assemblies to stop fighting flow at about 155F so running 160F is normal operation without a special valve. This is why the older systems had a second loop-back thermostat that allowed re-flow until the temp actually got higher then they'd force the flow to the radiator. The guys in India can tell what 75flbs _sounds_ like tho...

It has been said, "Some people don't know and you can't tell them" or the all ways astute, Larry the cable guy "You can't fix stupid" Also you might Google the "Dunning-Kruger Effect" to help you understand some of those E-mail comments.

Here, in the Yukon, Canada (Neighbour to Alaska) we sometimes get colder temps than -40 (Celsius, and Fahrenheit are equal at this -40) but I do not run my van below -25.. Yes, it is cold up here.. and mechanics are hard to get by, especially for diesels.

DON'T BUY PARTS unless and until you know WHY you are buying them. That is one of my biggest challenges- some turd on the phone will tell them "it's the injectors" and it almost gets like they are literally chomping at the bit to buy the stupid part. I don't buy anything until I know *exactly* why I am buying it.

Hi. I have a c15 6nz from a generator i put into a international semi truck. It has no jake brake. What is the best way to add a jake to it? Also it feels like all power is really down low. Would tuning be different on motor out of generator? Hauling 150,000lb gross offroad.

9:10. I call BS. I have seen with my own eyes a guy hook up batteries wrong leading to low voltage to the ECM just while cranking, not letting the injectors fire on a C10. It was in a 90s FLD daycab IIRC.

Where is your shop located at? I’m looking to start a camper conversion on an Oshkosh MTVR and I’d love for you to look the engine over and update anything that needs it. Do you do ECU modifications? It already has 450+ HP but it wouldn’t hurt to have a little more with all the added weight.

For over 30 years my dad has said, if your check engine light is on, it’s a bad O2 sensor. If you always guess the same thing eventually you’ll be correct. Now it’s a joke between me and my friend. Funny Video, Thanks.

The pushy thingys aren’t making fire. Is that because it has low horsetorques? C199 in a sedan. Help me plz

I like this kind of video, here’s my question. 2013 Cummins had an engine rebuild about 2 months later turbo went out CAC was replaced along with turbo, a month later truck started smoking white and starts missing and loosing power fuel rail pressure sensor was replaced problem fixed for about a week any thoughts?

-7 Fahrenheit (about -22 Celsius) is a pretty normal winter temperature in much of Canada. Whenever people ask how cold it gets here I just tell them -40, which is both true and easy for Americans to understand.

I have a couple of ball tearing expensive failures coming up for you from what we get turn up in our workshop, accountant supervision is advised, they normally go into PTSD when they get the bill.

I need a cummins ism expert. Have an odd problem. No codes I threw every part at it along with injectors harness ecm turbo. Vgt controller. Ran overhead and double checked 3 times. All new filters. Injection pump even put a cac. So I sent it to tri state mack and after 3 failed attempts it’s still there. The vgt actuator opens and shuts when you put the throttle on the floor. Like clock work. It’s will spool up then open back and forth. Dumping boost immediately.

#adeptape_rant 😂 Thanks Josh. It’s nice of you to try to help people. Some folks just don’t know how to describe a problem, which makes troubleshooting quite hard when the details they provide are all you have to go on. I run into the same thing in my line of work. Just today, in fact.

Please make more videos like this, I highly enjoy you pointing out some peoples stupidity 😂😂😂😂

Enjoy your flux retired now had 3406b Cat people inGTA LOOK AFTER it 20 years never let me down

Those people in Pakistan or where ever are very industries when working on anything. So much for a torque wrench,something maybe they can't afford. But with what they have available and they get the job done! Sorry appii I don't care to much about mice eaters,but I have put a wheelbarrow load of my comes apart often and the rear structure is next again. Use the quick valve and throw the plug away! But the trucker might be a ditch eater?

I used to hate service calls where you would request checking electrical, hydraulic function etc, then receive email within minutes stating the item is working, has voltage, current, flow etc. I would invent a switch number, valve number etc. Still get yes, that's fine, then apologise for giving an incorrect number. end of call. Feel your pain or replying.

Always frustrating when people want exact magical answers to vague questions. Like people that want you to tell them why the CEL is on, but don’t like you saying you’ll have to hook the computer to it.

Your videos helped me to properly rebuild my pot grinder and it's working better than new now! I never would have thought to check cylinder deck height and that was the problem all right. I wish CAT made one! Thanks Bro! 🐴

I know that i had a 34cat one time and every time i shifted into 5 gear my right nut would itch. I checked all the fuses and they were all good. never could find the problem. Ive sold the truck and got another one and never had that problem again. ....... im kidding 😂😂😂😂

Please tell freightliner this about their compression fitting going into the dryer. I actually broke a $1000 air dryer because they put some kind of sealant or lock tight on the compression fitting going into the dryer. It snapped the intake port off of the dry, and they charged $1000 to replace it at the dealer. This being a brand new truck that had around 10-15k miles on it, I doubt anyone had it apart before then.

The second question shows that most people don't know a damn thing about the vehicle they drive. About the torque, Indonesians also don't use torque wrenches. Everything is very often horrendously overtightened. Even lug nuts to the point of warping rotors and toasting wheel bearings.

3:00 I have a CAT 3126 had my clutch replaced and wouldn’t go past 55mph either but once I got up to that speed it would go into limp mode. My issue was that the transmission harness was disconnected

For the thermostat question, I’ve seen both temperatures used, actually use them myself. The thermostat temp is set in degrees Fahrenheit, so there is not much of a point changing them, since they make sense in relation to each other, and the manufacturer. However outside and inside temperatures are measured in Celsius. With the C4, I was in a cube truck that was geared so low, that 55 was about all it could do, hit engine governor at 65. Then again, this person’s truck could be a yard mule.

If the first driver is canadian he probably is talking about centigrade. We use a mix of metric and imperial in our day to day. Truck mechanics here most often talk about vehicle temperature using fahrenheit, becuase thats whats in the manuals and on the gauges of vehicle made in North America. When talking about the temp outside we pretty much exclusively use centigrade.

Torquing bolts makes the assembler more reliable on assembling reliable engines. You can tighten by feel 100 bolts and maybe 5 or 10 will not be torqued to spec. That means on one engine, there will be bolts not tightened correctly, and then, guess what! There will be broken bolts, leaks or bolts that go loose by vibration. Torquing to spec gives reliability and traceability.

Most engines built before the torque wrench was invented had the same life expectancy of a housefly. The guys rebuilding those engines over in some 3rd world country can buy lots of cheap knockoff parts and get by rebuilding them about every year. I wonder if all the guys saying you don’t have to use a torque wrench would be willing to pay for a rebuild without one .

I use a torque wrench daily and I can't rely on feel to get something correct. But I'm no Harry Stylist.

-7 isn’t really that cold. Here in Northern Canada it gets -40 some days and trucks need block heaters plugged in but they do eventually get up to operating temp.

If you don't want your drain plug washer f'ed up then quit over tightening the dam bolt. I never replace the washers on my vehicles or the vehicles that I service unless they were bad before I got to them. My son bought a used Toyota Corolla and I was showing him how to do a proper oil change, we struggled to get the plastic filter housing off because it was extremely over tightened and the oil pan drain plug flange was more than halfway through the aluminum washer. The replacement washer was still good 6 oil changes later and not so much as a week of oil leaked out. Same for the new plastic filter housing.

"Harry stylist..." Comment seems like it was from a different video. Sometimes, the video changes in the middle of a comment, and the comment goes on the new video instead of the one you're commenting on. RU-vid is a mess.

⚓️ Thanks Josh ♨️ yep ~ throw in the u tub watching while imbibing… may ‘splain some comments & questions 🤠

welcome to the internet 😁 considering AI is on the rise you'll prolly see more wacko's appearing in your comments section. nothing worse than a keyboard 'know it all' cowboy, except for an AI controlled bot 😵

Wait...there's two steps in logic??? At what step does the turbo kick in then?😂😂😂 Love the videos Adept!!!

The first question, coolant temp on the gauge could be fahrenheit, but he's in a metric country. Sounds like English is a second language.

Ive started to use a torque wrench more recently but found my cheap wrench was under spec so the injector seals i did lasted 6 months, i thought at the time it wasnt very tight at 25Nm and i was right... i only hope its because i was at the bottom of its range as i also did the flywheel bolts at 75Nm with it...😅😢

Step 1 of any diagnostic: Complete engine tear down. I’ve been doing it for 120 years 25 hours a day 8 days a week 👍

Sorry it took a couple days to email you back. I sent pictures of the supposed 6NZ. Waiting for a reply. Thanks

Back in the day before torque wrenches were common and engines were low compression lower revving, they were considered high mileage at 30 thousand miles . Also fatigue will cause a difference in how tight something feels.
