It takes a good man to own up to his mistakes ! MUCH RESPECT

Don't beat yourself up about it, mistakes happen. You're man enough to admit it. Great video all the same

My son is in tech school to be a maintenance tech for busses and trains. I'm going to show this video to him as an example of how to conduct yourself. If you make a mistake, own it and move on. Lesson learned. There is nothing that replaces honesty and competence. Thank you for being such a great example to everyone, regardless of what profession you are in. Also, thanks for all the comments from those that have been there and done that. They emphasized the importance of the lesson you have given us.

The amount of sheer respect I have for you is enormous, I’ve been there, standing outside the bosses office, wondering if there was a way I could make it seem like it wasn’t my fault, but I got more respect for owning it and the boss didn’t give me one lick of grief cause he knew I beat myself up enough for the both of us. Great job man

Must be one of the rarest things on RU-vid, somebody admitting they made a mistake. Much respect. I'm sorry I can't like this more than once.

Respect, that was honest reporting. And I for one think that you are a smart cookie when fault finding, a very good presenter and a great teacher too.

Hello! As a retired truck repairer I love to watch you working. I almost smell the trucks and sometimes I wonder why my hands are not dirty after an hour of working with you :) Many would have left out this video instead of revealing a mistake. That is what happen to all mechanics, we all make stupid mistakes sometimes. My worst was the gear which lay on the working table (instead of deep inside the gearbox) when I had finished the assembly of a gearbox in a truck :) Keep on the good work!

"experience" is what you get when you didn't get what you wanted !! old saying from my grandfather.

You called it. Air getting in to the oil. That was pure deductive reasoning and it takes huge intellect to reason one's way to an answer that is physically invisible. Well done.

Don't be so hard on yourself. As my father always told me, " if you don't make any mistakes, your not doing anything". I know how you feel though. Sometimes we just want to kick ourselves in the ass. But, it could have been worse.

when working on a US Submarine you MUST have the instruction of whatever it is you are working out, open, on the page with current step. Additionally the current step must be circled and the previous step with a line through the circle. One day I was cruising along because I knew the process via muscle memory and my supervisor came by and just hummed at me and gave a little frown... He asked a couple rhetorical questions about the book and said "I gotta go over there for 5 minutes and I'm gonna came back and inspect your process & progress." That was my queue to get my book keeping in order pronto. Turns out the Cap't was on his way down to inspect his boat and my supervisor was checking to make sure no one would have to be written up for allowing process to slack while the work completed was charging ahead.

I have to admit… anyone that embraces humility like you did and seem to do whenever it’s necessary is the absolute salt of our earth. I appreciate your work and how much you honor being truthful with your work. Much praise to you and your work.

No matter how good or bad of a mechanic you are there's always that ONE machine that will keep coming back to haunt you.

I though the theory on the oil pick up was well explained, and totally plausible, in a way you were still correct, not stupid by any means things happen.

It's Good that the customer brought it back instead of telling people you're rubbish and letting you fix problem. Everyone at some makes a mistake. Doesn't mean your bad mechanic just human.

It takes a big man to admit defeat and admit you were wrong. But to make a detailed video about cause and cure is unheard of. Most so called mechanics would no sooner admit defeat then he'd admit he sold it to a customer that way. Steller work my man, absolutely untouchable. Great videos and God bless:- )

Hey he who never made a mistake, never done anything. Thanks for all your great videos, love them and your presentation of them.

Education is always expensive. Sometimes painful.

U are not an idiot. Best channel I have found since the passing of Diesel Tech Ron.

We're all human, Wes..... Don't feel bad, we've all done stuff like this. And if someone tells you they haven't made this type of mistake, they're either lying to you or it just hasn't happened to them yet. But don't worry, it will. A true mechanic/technician can find and fix his mistakes. Good work, Sir!

Hey the last perfect guy was nailed to a cross, you’re only human.

Once again, a very impressive, well thought out presentation and explanation. Always look forward to your videos. Great job .

But the bright side is you will never make that mistake again and you helped save one of us the same fate . Thank you

I have been working on my own cars for nearly 30 years, my mistakes have never injured or killed anyone and never cost more than visiting a garage. I see that as success.

Let us bow our heads and give a moment of silence for our brother Wes, who finished a project and committed the sin of Ignoring the Extra Bolts. We have all been there, too. Amen.

I am gong to make sure the doors are locked when that thing goes. To funny!!!! Great video!

Wes, we’ve all been there. You can’t screw anything up if you don’t do anything!

Mistakes are always better teachers than successes. Thanks for showing us reality

Good work Wes. You shouldn't be hard on yourself. You're man enough to admit the easy mistake. I make my share of silly mistakes. Take care

Don’t feel bad about it, it just a learning thing. Been in a Machine trade for 48 year and still make mistakes. Just move on bud. Enjoy your videos.

Win with humility, lose with dignity. Good job, teacher.

You're not an idiot- you're a human who makes mistakes. I'm glad you've repaired it and returned the truck to service. You're a fine troubleshooter and a conscientious guy. You made a mistake and corrected it. Nothing was wrecked or ruined. You are a better mechanic after this experiment. I admire your hard work operating your own business. God bless.

Thank God they still put that pink thingy on pencils so we’re still allowed to be human. Anyone who hasn’t messed up just picked up his first wrench.

Certainly appreciate the integrity to own up to a mistake. Always aiming for a perfect job done so the amount of mistakes is less. More than once I have finished my own repairs to figure out I messed up some step along the way. Never fun especially when time is of the essence. Again appreciate the sharing and integrity so we can learn along with you.

In a world full of "pass the buckers", and flat out bullshitters, well an honest man is a rare treasure and you are a fine good man. And no one is harder on ourselves then our own self. I'm glad I'm not the only man who is the way I am.

Those old plowtrucks and salt trucks y'all have up there have to be one of your biggest nightmares to work on.

Ahhh...a day in the classroom at the School of Hard Knocks!! You never forget those lessons, especially when they hit the wallet. Thanks for being honest and showing us your mistake. We have all done it at some point. Anyone says differently is not being honest.

It takes a brave man to admit his mistakes on camera, but like ye said it may prevent it happening to someone else. Respect to you!!

I've always told coworkers, or apprentice mechanics or anyone who just in general likes working on cars. The best thing you can do, is always own your mistakes. A mechanic that makes a mistake and admits it is a honest human being, and the best mentality a mechanic can have. If you make a mistake and know you did, but are too prideful to admit you're wrong go do something else. Hats off man, we all make mistakes at some point in our careers and we all know you didn't do it intentionally. I don't even work on big trucks, but i love your videos.

News flash......we all mess up. I respect the fact that you wanted your viewers to know you aren't perfect either. Well done Wes.

I take my hat off to you. You are an honest man. That’s why I enjoy watching your videos. Don’t beat yourself up. Keep the great videos coming.

This video is the reason I watch this channel. You tell it exactly how it is. Total respect dude!

Just keep one thing in mind Wes. There has only ever been one "Perfect" person EVER! And he could walk on water. The mere fact that you are willing to own up to your mistakes makes you special. There are way too many people who refuse to take responsibility for their actions. My hat is off to you.

you showed the customer that you can be trusted, and that you did not fabricate another excuse...good man..it will be realized in more business....

Wes you are an honest man you will go far. People are craving your kind of honesty and know how.

None of us are perfect Wes but I’d say you are closer than most just for owning your mistake and educating us on being a real man👍

No one is easier to fool than yourself.Wise beyond your years ,young man!Keep up the great work.Greetings from St Antoine Abbe Quebec Canada!

You are human. Not your first mistake, won't be your last. I admit my mistakes, no matter the consequences. Mad props for your honesty.

I've worked on these engines for a while at a dealership and a private fleet. I can't believe it built base engine oil pressure without those bolts. Blows my mind. I like that you admitted your faults. Good luck man

Honest, humble and a mechanic, unheard of!

I respect a man who owns up to his mistakes and then show us what the mistake you made was. Don't beat your self up over it. As you said your human and humans make mistakes. Your a good teacher too I have learned a lot from you.

You held your hands up to your mistake, top man, top marks for that. Don’t forget that the bloke who’s never made a mistake has never made anything, atb from England

Don't beat your self down to much. I think your a good mechanic and even good mechanics have a bad day.

Wes, it is a very large pain to admit a mistake, especially in front of many people. Great job, you are great mechanic, a genius at what you do, the fix for any mistake to try to never make it again. No mistakes, no learning!! No learning, nothing gained. Great job as always!!

In situations like this I always revert to Occam's Razor. When faced with two wildly different explanations for a particular occurance it's human nature to want to believe in the most elaborate and fantastically impossible explanation. In most cases its the most simple explanation of the two. You are a joy to watch and I respect your willingness to keep learning and growing as a human. I'm just so glad that's not me under that god awful truck!!

Just have to mirror many comments on this. It takes allot of character to own up to our humanity in front of the world. We have all been there, and few have handled it with such honor. Thank you for sharing

Takes some big huevos to post a video like this on RU-vid and admit your mistake. Well done. I really enjoy the channel, keep up the great work!

Good to get a definitive diagnosis. Frustration to find that out! We have all done this type of thing.

If the top brake air hose was a swivel, and the bottom wasn’t, somebody didn’t crack the swivel loose on top when they replaced the can the last time and didn’t count how many times they twisted when they went back on. You’re an excellent mechanic and a humble man. Thanks for giving a great lesson on intl engines.

I have a 2001 DT466E with less than 70K miles. Runs excellent. I love this video. You give me confidence that I could actually figure out future problems. I am a subscriber.

Great video on the explanation of the issues. As a long time diesel tech my self it takes a confident diesel tech to own up to his mistakes. Were all human and it does happen.. keep up the awesome videos

In the 40 plus years I spent on the wrenches, I made my fair share of mistakes. I used to get all upset about it, later in life I turned it more into a learning episode. A few of them were pretty costly.

Takes guts to broadcast your mistake fair play to you,your a brilliant mechanic and I love watching your channel 👍🏻👍🏻👍🏻👍🏻

Wow! So crazy... I did the same exact thing many years ago with the same two bolts. Those two bolts have been in my tool box all these years and have haunted my dreams, because I knew better.

When I was a supervisor I always told my employees, never feel bad about making a mistake. Mistakes are part of learning.

I'm enjoying your channel, your honesty, tips, down to earth approach and the fact that you own up to your mistakes and share them... The bringing back to life of so much "forgotten dead' machinery is of great interest... Thank you :)

You are not an Idiot, an idiot would blame someone else for their mistake. Thanks for sharing. Great video!

I once had a guy call me up to do timing belt job on his Acura MDX told me the year make and model I ordered the parts he dropped it off a week later I did the job noticed the new belt slightly narrower than the old but proceed to finish on start up the belt rode off a tensioner and jumped time bending valves and destroying my ego and ending my perfect record of having ever making a mistake on something I had done so many times on so many different engines. He gave me the wrong year of his own car by one year and I never confirmed the year to the parts, I bought him a new engine and installed it for free he remains to this day loyal customer and good friend but the ribbing he gives me still burns like hell, that mangled belt still hangs in my shop to this day as a reminder before I start anything I work on to wait ten min and think about everything. It made me a better mechanic in the end.

I feel for you working with all the rust. We don't have rust in my part of Texas, but after years of heat and sun, plastic tabs and connectors become brittle and crumble in your hand, so sometimes even simple bulb changes require some wiring work.

Very interesting video, well done on admitting your mistakes and learning from them!

We all make mistakes. Its how you handle them that makes the difference. We watch your videos because your a straight, up honest guy.

I consider myself a dam good mechanic but Everytime I WATCH WES WORK I learn something new,Wes you are by far one of the best and most thorough mechanics I've ever seen and I enjoy watching you work lol

It happens to the best of us. Thank you for sharing so honestly .

Well Wes it again was a joy to see you work🛠👍 and thanks for sharing that mistake 😉

I’ve got seat time in a 4900 with a 530 and it was my favorite truck to drive once it warmed up. Enjoy seeing these old goats on your channel.

22:53 That face and that feeling is so damn relatable. Had a supercharger suck in an old piece of gasket when I was swapping a throttle body on a Mustang. That simple 2 second brain fart turned a 10 minute job in to a half day job. Had to pull the whole supercharger off, clean out the old gasket pieces, inspect the rotors for damage, etc. We've all been there to some extent. At least you were able to find the smoking gun, and like others have said, kudos for owning up to it. It's those aggravating moments that we really learn from. Keep up the good work.

Shit happens...we all have done something similar when we started out...hell I did it more than once

Sends chills down my spine for you to go thru this, but you are a great professional.

You are a fantastically humble man, agree with others “DON’T BEAT YOURSELF UP” but you are man enough to own a simple human error😊. Love your site learn so much.

At least you are honest. I just had a mechanic screw me over on an injector job. He charged me for all the injectors to be replaced, and I trusted he did the work I paid for. A week later I was having issues again with diesel in my oil. Then I was interested in looking for myself and I pulled off the valve covers and the mechanic only replaced 2 of the 8 injectors. I’m glad their are still some honest mechanics out there. Love your channel Wes.

Oh, it's the Red Nemesis again! As frustrating as this must have been, it did make for a fascinating video, better than any drama on TV. I loved your theory about aerated oil, and I was almost as disappointed as you sounded when the pickup tube came back good. The other explanations weren't nearly as convincing. I'm just glad you finally got to the bottom of it. That was a sweet sound when it just started up and ticked over.

Also thanks for the tip on the brakes, I cage brakes for my safety but its always nice to see other people, Good idea for the hoses.

Hey pal...you are not an idiot. I know some idiots and they’re not like you. You’re a very good mechanic that made a mistake. I would hire you in a second.

i remember these old trucks back in the day they ran great for years simple and easy

Mistakes suck, especially expensive ones. But they’re a part of life.

This time you done it right, remember we all make mistake's, just another day..!

I have always had a pancake in the truck with me. 4 or 5 times from the early 80's. Its saved me from a service call on the road.

@ 36:16 (I was meant to go shopping that exact time ago!) It fired instantly. Made me giggle out loud! (And I'm watching this on my phone, sitting on the end of the bed all alone) Great video! I learn something new every time I watch your problem solving & repair techniques. Plus! We should all learn the big one in this video. It's what the late, great Richard Feynman said about looking at results. The easiest person to fool is yourself! It's a hard one to learn but we all have that one time that taught us. Good stuff Wes! Yes, even with those two bolts. How many of us who hadn't learned that big lesson would've made the "I don't know what we fixed, but we fixed it!" video & just hid the cock-up? Thanks for showing us the right way Wes. Great video. Loved it!

For a kid, you do damn fine work.

Fair play to your honest side🤙

Stuff occurs! It really sucks when it happens, but on the bright side, there was no catastrophic failure! Thanks, Wes!

Wes, I'd sooner have a mechanic admit his mistakes, rather than one that blames other mechanics or nonexistent "Factory" defects to cover up his work. Honesty is the most valuable check you'll ever write.

Shit happens man. A mistake every now then doesn't do you any harm, found it humbles me a bit and makes me take more care.

Man o man this brings back memories. Fall 2006. 1994 Ford F-250 idi turbo. Engine died, pulled motor. Melted piston cylinder 7. Had machine shop resleeve. Put back together and in truck, start and ran for 4 minutes then boom. Took back out and apart. Turns out during assembly as I was finishing up #8 connecting rod wrist pin friend stopped by and asked what I was doing. Distracted, forgot to put in last wrist pin clip. Once started, pin slid and piston collapsed breaking inner cylinder wall. Take back out, have machine shop put new sleeve in #8. Put pack together, start truck. Begins leaking out of the back somewhere. Found I had forgot to reinstall small drain plugs behind flex plate. Pull back out, install plugs, reinstall. After lots of money and time, it hurt me deep down in many ways. So many chances to beat myself up, quit and blame. But I’m known for perseverance. And I know we make mistakes, really unnecessary mistakes but that’s how we learn. Or preferably watching others

Wes I enjoy your videos because you tell it like it is, mistakes and all. Makes me feel good as I constantly make my share of dumb errors thanks for keeping it real !

I couldn't really see the fault in the truck but I can see allot of blame on the owner of the truck.

You can work on my vehicles anytime, honestly is the best policy. Thanks for sharing your mishap

The time you take…. Never assuming the viewer cannot understand. I appreciate it. Be well friend.

Welcome to humanity, Wes. Your willingness to not only admit a mistake but then put it out for thousands of folks to see it in a most self-depreciating way makes you the guy I would bring my mechanical troubles to fix. You developed a theory about the 466's issue that was pretty amazing AND you had a perfect alabi with the pickup tube. No one ever needed to know it was your mistake; it would have been a great video plus an opportunity to bill it all to the customer if you choose to do so. The fact that you "came clean" plus ate 10 hours of labor plus most if not all the parts costs tells me you would not make it in most other shops and your customers need to treat you like a gift from the gods!! A nearly flawless mechanic who armits and covers his mistakes (few that they may be) and takes the time to scope out the whole machine for deficiencies and reports them for the owner to either fix or keep an eye on. You are a gem, friend.

Credit to you Wes for being honest, and because of that it made a great video. Al.
