They need more sponsors to pay for it

Probably wouldn’t change my mind either 😂😂😂
yea dude they should do a hi low porsche series
MrBeast and then Porsche I was like holy shit we’re going somewhere!!!!❤❤❤❤ hells yes boy!!!
Well, they've been sponsored by Porsche before when Nolan talked about the Cayenne in one of his Wheelhouse episodes. That sponsored bit was talking about their pre-owned Porsche program.
Respect to the young lady, she's legit.. Whoever's in charge of getting sponsors needs a massive raise.
Angelina is the only one who recognised that drilling the bushing out was damaging the part.
Definitely bad advice. Well done Angelina.
It might also be the editing. They seem to cut a lot of content and commentary so they don't have four experts all saying the same thing, but complementing each other.
Nope run a drill bit in reverse it don’t cut that’s a damn good hack
@@droptine7848
Nope.
A drill in reverse wont drill a hole, it can still do plenty of damage being used as it was in the video.
She responds as a teacher. She teaches at a college. The other 2 respond like shoo owners. She’s always going to respond in the “least damage possible” whereas the other 2 will always respond in a “If it doesn’t break anything than it works.” *Potential Damages* unless immediately apparent and costly, aren’t considered in a lot of shops.
Drill in reverse, the bushing likely won't come out. In reverse, the bit will likely score up the inside, but that's not too big a deal. In forward, the drill bit will likely cause deeper scratches, water will get in with capillary action and cause rusting over a Long period of time. Good luck pushing the new bushing in with the drill. Little gain, imo.
Justin looked so happy doing the sponsored segment. I know he’s been around a little bit now but it’s so nice seeing Justin become comfortable on camera and becoming an amazing host. It’s like he’s been doing it forever he’s become a natural.
Yeah I remember when he first started out he was so awkward and looked kinda nervous, but I'm glad he's start to get more comfortable and open. I feel like the energy and just friendship of all the guys at Donut is just infectious as FUCK. It's great to see the chemistry between everyone and it makes me smile that Justin is getting along well. Also, fucking PORSCHE sponsored this video? Damn that's cool

@Ashley White *insert scottish accent* disgusting.
True man it goes bigger and bigger
Back in the 80s, a friend of mine did the head work for a well known NASCAR team. He said after extensive flow bench testing, they determined there was better atomization of the intake charge when the intake ports were finished with a 120 grit sandpaper roll and the exhaust ports were finished to a mirror finish to minimize carbon build up.
came here to say the same. i had a well known machinist build the heads for my buell engine and he finished the intake ports rough for better atomization of the fuel. that bike absolutely ripped
that depends entirely on the engine, 80's were still using carburetor's so atomisation was important. That no longer is necessary, dead set smooth is better in the vast majority of cars after the 00's with fuel injection.
angelina should have her own segment. I’d watch just her reacting to stuff. Loved her explanations
Definitely
She needs to get back on her RUclips channel

She definitely stands out. Incredibly smart.
She's got the looks with intelligence to back it up, not common nowadays with social media clout.
I love the difference between an instructor and the two shop owners on when something is "bad practice" vs "gotta do what you gotta do" 😂
I was wondering about the differences in their approaches why she was so much stricter and going after the ideal everytime. While the others were much more practical and focused on the reality. I didn't even think about the fact that she is an instructor and they are practicing technicians.
@Aaron Burkeen it would most likely be due to the way the automotive instructor has to teach. The main certification all automotive instructors are trained for is the ASE certification test, the instructor knows that test to a tee they change their couses to meet that tests standards. Though with it being a test it is hard to test real world situations so many times the ASE exam is a lot more strict as the automotive instructor is
She looks very incompetent ... That big lecture for destroing ECU was pretty lame and untrue
@@miletinic920 Right, let's base our determination of competence on your biased opinion of what she looks like. good job, troll.
I think the real difference comes in when you consider "who do you want to have working on your car" vs "whose actually cheap enough to work on your car"...
Sponsored by Porsche! Congrats for this achievement and reward! You deserve it. 🎉
I am not a fan of Porsche but it is impressive that Donut has car manufacturer sponsor
Bro they're a massive multi-media conglomerate - the people you see on the channel don't run donut whatsoever. It's a corporate company.

Paul definitely seems like the kind of guy that if you're a customer, you want him watching over the shop because he will make sure things are done right, and if you're his employee you'd better have your game together because he will put you out on your ass in a heartbeat if you screw around.
I’ve done the rear brake delete trick. I’ve also been pushed by the rear wheel drive through an intersection with my front only brakes locked in the rain. Almost lost my life that day. After that I just put it in neutral before I got to the light. Made it home safely to change my shorts.
As someone currently apprenticing at a porsche dealer I thought the sponsor ad was insanely cool today. Not only did I not skip it, I watched twice.
I had to skip it because I know I’ll never own a Porsche. Which makes me sad but I am happy for ye over there :D
Is it worth it to work at a Porsche dealer? Are you a tech or sales?
@Taylor Smith I'm a tech and I think it's worth it. I get to see so many cool things that most mechanics don't get to, and attend porsche specific technical training courses. There are lots of extra hoops to jump through, and lots of attention to detail which is expected.
That’s awesome, I’m hoping to jump over as in house counsel to Porsche NA in a few years.
@@taylorsmith3031 Of course its worth working at a Porsche dealer, those guys charge you Ferrari/Lamborghini repair prices, even if they did absolutely nothing.
Your salary will be amazing.
The fact that you guys partnered with Porsche to offer this kind of program is incredible. Hats off to whoever came up with this idea. Sky is the limit all around!
Yeah honestly they’ve come so far I love to see it
Higher standards, I’m loving it!
Lots of laughs. Hope there's more videos like this! "Class 8" mechanic here since the late 80s. Some of the tricks I know people argue and can't believe until they try it or you do it in front of them and prove it. Example: Heating a bearing in an oven so it slides right on a shaft instead of wrestling with it on a press.
Brought a triumph head to a machine shop that mostly did race motors. Did a port and polish job myself that i was quite proud of, he told me the exhaust ports were perfect but the intake sides benefited from being a little textured, his explanation was you wanted to create turbulence when the air/gas entered the chamber for a more complete burn.
The Porsche sponsorship is INSANE! Whaaat! Well done Donut!

Also ps "they aren't going to send it to you dry" when it comes to turbos, work for Hyundai 🤣
I had an old Ford Ranger on the Carolina coast years ago… the brake line rusted out and I was spraying brake fluid down the highway till there was nothing left. I made it to the exit, the manual transmission made it possible to control the speed a bit, found the leak and was able to cut it to pinch it off. I was young and saved the day… Just one of those golden memories. 😊

As a mechanical engineer, I think we should look more into the dimple concept. I don't think it will have huge increase in power, but I'm curious to know what will happen. Technically the dimples should reduce drag.
Agreed. You see dimpling on some high performance cars' underbelly panels. They wouldn't bother if the effect were unmeasurable. The dimpling also increases the internal volume of the intake runner, which may or may not be beneficial. A good calibrated flow bench might give you some data, but you'd really have to do the test on an engine dynamometer to prove the hypothesis. In any case, I doubt it's really worth the effort if you were trying to get significant gains.
Small engine companies like Sthil already do it. Although it's an inverse dimple. It should aid in cutting low pressure areas and also (my guess) aids in cooling effects in carbureted engines. Port injection too for that matter.
The way I understood it air has less resistance against air, instead of air against a metal surface..... Have seen some pro's porting that left a rougher surface instead of polishing. Claiming these exact results
I was thinking the same thing. Dimpling breaks up laminar flow, which sticks to the smooth surface, creating a low pressure film. This low pressure film slows the air flow for a distance away from the surface, depending on air speed. The dimples create little vortices, with the direction of rotation going in the same direction as the air flow. This stops the laminar flow and the associated air flow reduction. Think of it as fluid ball bearings. The dimple diameters and depths need to be calculated based on pressure and flow rate so their effect does not go into the desired airflow area. Creating random dimples may or may not help performance. Automotive maufacturers don't do this as it's very time consuming to machine, thus increasing the part cost. The performance gain might not be enough to create a sale, especially if a larger diameter pipe could fit in the same location.
they produce turbulence and break air molecule to the max, more the molecule is broke tinner is the air .thecnicaly you can get more air plus it get the intake bigger. porting guys know theyre shit. some set up are better polish other dimple like that .
XD The ol battery cable reverso trick. Did that by mistake on the school's tug in our hangar, right in front of the instructor. He laughed when it sparked at me and I jumped back. He was like "Ok, I will give you one more try to NOT kill yourself."
Seen a bunch of these videos, and I think this is my favorite trio of mechanics.
You gotta be really careful refilling cans like that. They're designed to be disposable so they're not reinforced enough to be repressurized safely and walls or valves can easily fail.
Not only that, for air you need much thicker walls to withstand pressure.
I mean, most folks at home are pushing 90-125psi, but that's probably high for the can. Gentle bursts highly recommended, dont try to fill it til she blows for sure
@@kjur18 Don't be daft. 90psi is 90psi. Doesn't matter if it's air, water, butane or anything. The only reason the air tank for a compressor might need to be extra thick, is that you'll end up with condensation inside the tank, which will rust it out. So the walls of the tank need to be thick enough to survive some corrosion. After a few years the tank may need to be replaced due to internal corrosion. OR, use a dryer on the compressor outlet.
@@noxious89123 Well, yeah. But keep in mind that whatever gas they use in spray cans is in liquid form at that pressure, so it's more efficient as a propellant. To turn air into liquid you need much more pressure. As Wiki says on Canned Air: "True liquid air is not practical, as it cannot be stored in metal spray cans due to extreme pressure and temperature requirements. Common duster gases include hydrocarbon alkanes, like butane, propane, and isobutane, and fluorocarbons like 1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2-tetrafluoroethane which are used because of their lower flammability. "
Not only that, but spray cans are not filled with pressurized air. It's a refrigerant that becomes a liquid at a relatively low pressure. In the same way that liquid water can only get so hot before it boils, the refrigerants can only get a little pressure build up before they condense.
Idk who needs to or will see this but Paul and Lextech are such a good shop! I know this isnt a review page but they fr deserve the recognition. I brought my ‘16 Civic to them thinking I had an issue w my alternator and they originally told me me it was the alternator, but Paul personally came up to me saying it wasn’t the alternator as it began to charge when different buttons were being pressed. He recommended me to a shop that specializes in Hondas to have them check it out. Paul saved me from a $700+ bill! Definitely recommend them for basic check ups and toyota/lexus maintenance! 10/10!!
The dimpled inlet runner is done on wet intakes to aid atomisation, a polished runner can encourage fuel drop out on the runner wall. In a dry runner smooth but not polished approx cross cut with 120grit is best as it allows undisturbed flow while the flat surface reduces flow resistance caused by eddy currents at the boundary.
The wrench in the screwdriver may not seem new to most at all. I’m glad you guys explained how the screwdriver handle is actually intentionally designed for box, open end and even pliers or channel locks. What that guy was actually showing is that he can now apply tremendous downward force into the head for less chance of tooling. It alleviates your arms focus on downward AND twisting force. You now divide the two perpendicular forces between two different more focused/balanced levers. and I have used the technique all the time even on the smallest corroded appliances or even in framing construction and carpentry. It’s basically the same as resting your chest or shoulder right against the impact or screw gun like it’s a firearm.
Jeri’s love for the power brake hack while everyone else hates it makes me happy for some reason. He just personifies MO POWA BABY!

It will only work on old vehicles, they make new cars have brake lines that have a front and back brake connected to it so its safer if one gives out
“It’s only a dollar my dude” that shit killed me 😂😂😂

Tension bands are the best imo. I replaced the original ones on my car when I changed the 32 year old coolant pipes for brand new reinforced ones (thicker). Used the braces with the bolt and guess what? One snapped mid trip and lost all my coolant in a rainy Christmas night, 30 miles from home in the middle of the mountains. Called my father that brought tools and materials. Had to dissemble the battery tray to get to that pipe and seal it, 30 mins in the pouring rain.
Got lucky though because the 32 year old ECM warned with Check Engine light. Otherwise, the engine would be fried. Got new tension bands adequate to the size of the new pipes, took out all the braces and never lost a drop ever since. Suzuki knows best.
13:45 That is exactly why you do not connect the Negative clamp onto the battery at the source vehicle iow the vehicle with the good battery but instead clamp that cable to somewhere on the frame to ground it so that some wrong connection or if the faulty target battery does something crazy, you do NOT damage the good battery in the process.

For the dimples one you shoulda actually consulted an aerospace engineer. Yes dimples do create vortex but that's what helps create a boundary layer and allow for laminar flow in a tube
a lot of factors there, but yes, I wouldn't be shocked if that moved air more efficiently
@@Dies1r4e it's also meant for naturally aspirated single point and multi point injection systems so fuel would mix better with air and that increases slightly engine power, about direct fuel injection systems i don't know, haven't seen for them this porting style, but for turbos it's best to make it as smooth as possible
Ive seen some explanations about why sometimes dimples make a better airflow too, I dunno if this is the case but it sure isn't as simple as "dimples are bad" anyway.
modern cars have all kinds of sensors that measure exactly how much air and fuel are getting into the engine. so yes, it does improve airflow, but it usually doesn‘t increase power because the ECU will adjust boost etc. accordingly
Golfball
About the repressurizing of a spray can. I don't think that's a safe way to go about it. If you do, PLEASE be careful. You can over pressurize the can, and it can explode. You could wind up with metal pieces where you don't want them (in your abdomen or head, for example).
I have heard many people speak of a "main fuse" in a vehicle but after 45+ years working them I still haven't found one.

And shaft..lol
The benefit of 2:35 is that you can focus less on trying to torque the screwdriver and more on applying downward force to keep the driver from skipping out of the screw and stripping it. It gives you better control. Impact screwdrivers are generally better but in tight spaces you can get this trick going with a prybar on the back end of the screwdriver too in order to apply much more force than you would normally.
I love how they were all so impressed by the thumb thing. It's something so simple and obvious when you see it, that you can't believe you'd never thought of it before.

You won't be hired unless you have prior experience in european or Porsche cars. You missed the whole point of the ad. You apply for a non tech job to be eligible to apply for their service technician training program. Porsche won't let you touch anything mechanical without the first level of certification and that's just a glorified lube tech position till you start gaining more time and certifications under your belt.
I love these videos. As a mechanic of 15 years I can say Paul is a G and knows his shit. The girl is a little too by the book sometimes and it makes sense since she's an instructor.
I was just thinking, as someone who knows next to nothing about cars, if I had to pick my mechanic to fix my car out of all these, it would probably be Paul or Angelina based solely off my impression from watching the video.
As a mechanic in the making as soon as I saw they said no to the misfire diag I thought it was a good hack but I also only did this with distributor systems
No matter the trade, an instructor teachers you the rules.
At work the good experienced guys teach you what exactly the rules do and why, they also know why the rules change when things get modded etc and what the new rules are.
instructor?? id would of said 1st or 2nd year apprentice ,its 2022 i fully understand why shes there
By the book is sometimes harder, but ensures the job is done correctly. I've taken plenty of shortcuts that have worked, but could have led to other problems if they didn't. I think being cautious of stuff like that is fair. The dude drilling out the bushing, for example, could definitely have scraped the inside and maybe it will eventually not sit in correctly.
Walking that bushing out with a drill bit is legit. Definitely gonna do damage to the bushing before he starts eating into the metal with the bit.
That power balance test. Aircraft (ones with internal combustion engines at least) use a similar technique, though they are designed to, to test the magnetos. While you're doing your ground tests prior to a flight, you have both sets of magnetos running. The ignition actually has a way to shut off one set, or the other. You sit at idol with both on. You switch to one on, switch to both on, switch to the other on, back to both on. This tells you how each set is performing. You do notice a slight power loss when running on one, but it tells you if they are performing nominally, or if one is doing bubkis. If you switch to your rights and you get knocking and a rough engine, you know somethings wrong.
If you're flying and you get knocking and a rough engine on power input during runup, your piston sleeve has disintegrated on the ground at FIN.
About the crossed-wires jumpstart part... I once made this mistake because my friend's car had the red positive cap installed on the negative lead and vice-versa, and I took that as good enough info. Luckily, it started smoking at the terminal almost immediately so we pulled it and no damage was done, but ALWAYS check for the embossed "+" and "-" on the plastic of the battery, and don't trust that the black and red caps are installed correctly!
that's solid advice ty
I've done this too at work with tractors before too😅 same thing wrong coloured covers on 1
Also the positive terminal is slightly bigger
Same thing happened to me. I was helping a friend, and my glasses prescription was so bad I couldn't see the +/- marks (it was a VW Golf and the battery is way back by the windshield). I think I turned green when I realized what happened. I was terrified I'd wrecked her car.
I've also seen newer cars that don't have red for positive, it's just black for both. If you can't see the + and - on the battery, you've then gotta follow the cables to try and figure out which one is ground.
If I'm not mistaken, dimpling an intake pipe like that one clip is actually better than a smooth flat surface. The dimples create air pockets/vortex's and those air pockets/vortex's act as a cushion for the air and increase velocity of the air flowing through the pipe. Now, this would almost be negligible on a "low horsepower" car (I'd guess below 1000hp) but would be beneficial on high performance car (over 1000hp) where every little thing matters. I remember watching a video where some engineers were talking about the amount of work and effort that went into a 2000hp (i think) GTR and how they got to a point where the smallest changes would net them a few hp as they hit the limits of the turbos and engine. I'd imagine they would have done this to their heads as there is some scientific backing behind a dimpled pipe leading to higher air velocity. Feel free to let me know if I'm wrong but I'm pretty sure I'm right.
Well just like a golf ball would like to see numbers of before and after.
@@chrisstuefen2386 there's plenty of research papers on the topic, a simple Google search will provide a plethora of information on the topic.
Best videos. 5 videos in and definitely a lifer now. Learning so much new shit. U all not responsible for the finger indention trick which has changed my life the second i seen it but learn a ton from y'all. Thx🤘
The "golfball" dimpling decreases the resistance the golfball requires to travel through the air by providing a small pocket of more still air surrounding and clinging to the ball that allows it to slip through air more easily. If you think of a golfball sized obstruction in a pipe, the mass flow around the ball would actually be decreased by the dimples but the force exerted on the ball is lower... so on your intake this would actually lower flow rate.
Heya guys, so @9:18 , when he is dimpling the metal, that is a process to increase atomization of the oxygen and fuel. its more common to see them in the valve ports as well as the entire upper intake. Through micrometering, its shown that the increased breakup of the molecules helps with performance. There are slight out-weighs through Atomization>Surface area. But through some instances, it performs better. There is a picture on the internet somewhere talking about why some Top-Fuel drag teams cover their work areas and engines with towels, so the competition can't see the ports or intakes. the photo was of a candid shot peeking under a towel and seeing the entire inside if the top half completely covered in those dimples, but much more intricate. Hope this helps! Much Love!
Thankfully someone typed this out to save me the trouble 👍🤣
I just wish that the commentators had said something like, I've never seen this or I don't understand what they're doing so rather not comment. I would have given them more respect for admitting a lack of knowledge on something, nobody knows everything and no-one is infallible.
@@TheRealShambo halfway through typing I was like "crap. I'm invested into this comment" lol
@@TheRealShambo Agreed
Also, air bubbles will form and sit in the dimples. Air has less resistance than metal.
The golf ball dimpling is actually something Mythbusters tested in one of their episodes. Would be worth looking into further!
The issue is that the area used to dimple woukd be better off just being opened up. I think the concept is that the large dimples create a buffer zone for air to ride over increasing velocity. Problem is the buffer it creates is larger than actually helps
From what I've seen you don't dimple intakes like this unless it's running a carburetor. It's for fuel atomization.
@@suprafastmafc the dimpling works because turbulent flow seperates later than laminar flow on the trailing edge of a ball, and dimples are a nice symmetrical way to create turbulence on a ball. Unless you have flow seperation, dimples will make your airflow worse.
As for the dumplings on the intake. Yes it provides extra turbulence so the air fuel mixes better, but it also increases air velocity. Because yeah it's not a golf ball, but physics are physics. Liquids move across a thin layer of itself and it actually reduces friction because the dimples create that microscopic layer of turbulent air. The rest of the air flow isn't even contacting the metal anymore.
You can buy pistons with this, and I've seen it on alot of diesels.
You need to RnD it to get a more effective pattern, (it doesn't have to look exactly like a goofball pattern) the people who make pistons have a patented design, but I imagine a couple hours of fluid dynamics study will help you figure out what patterns have what effect.
The dimples reduce friction because there's less direct contact between the air and the walls. Instead the air rides on top of small vortices, which is why this is done several high speed applications.
I'm surprised more dealerships/brands haven't done ads like Porsche in this video. I feel like this is the perfect audience to have good conversion on ads like this.
That's because nothing breaks down at the rate of German plastic.
The way she laid out and described all the steps in those process's was fantastic...Girl knows her shit.
and she hella cute too
I liked how she commented about the memory of dented metal. I assume that willingness to pop back into its original shape probably degrades over time so I would think that it's best to get dents fixed sooner rather than later especially when using paintless dent repair.
@@pkdude5334 yes and no in my experience...If there are no creases or hard lines in the panel, you should be able to work it back to normal with little issue... but, going back to what you said about time, the longer you leave it, better chance it develops hard lines and can't be straightened out without real work
Only real gripe I have is the power balance test. Yes it increases the risk of damaging the driver for the coil; but you can have a screw driver or test light very close when you pull the ignition wire so that if the coil is good the electrical current has a good ground to go to. I have done plenty of these tests on older cars and never had a issue pulling the coil wire. Not saying she's wrong, just adding on to what is good practice.
@@fightingfalconfan no such thing as a power balance test 😂. He was checking for a misfire
I did valves on a 2010 Hyundai accent after a timing belt broke. My valve spring compressor didn’t fit so I used a socket, hammer, and egg roll wrapper to get the clips back in lmao.
Bread doesn't just work for clutch pilot bearings. If you have to solder copper pipe but the upstream shutoff valve is still dribbling a bit of water, plumbers will often stuff a bread plug into the pipe so they can keep the joint dry as they solder it. Take the aerator off the downstream faucet, turn on the water supply, and the bread plug vanishes down the drain.
I like that Angelina was the dissenting voice in many of the iffy hacks because she knew there were better ways to do the things they were doing and therefore it wasn't a hack.
She really knew her shit and I've the assignment.
She's the one I would go to for regular maintenance and repair work, the other two I would go to for an undiagnosable/irregular repair.
Nothing to do with who is better, simply that strange issues sometimes require strange solutions that probably aren't standard but fix the problem.
But I'd trust her to follow manufacturers procedure and have the right tools to do the cleanest most professional job.
@@CheeryRhymes The guys id trust to get a beater going from point a to point b, but I wouldn't let them anywhere near a new car.
The fact is that some people will (either subconsciously or consciously) think that it's okay if they do something jank or outright dangerous with their vehicle, because they don't care if they get hurt. They never think about if someone else gets hurt. Look at the idiots that had that "show car" on the road and rear ended a minivan with family in it. The only brakes that worked were the front ones and they got cooked in seconds. They didn't care and almost killed children over it.

You absolutely 100% need to prelube your turbos (and entire lube oil system) if you’re doing a swing or overhaul. Don’t do it like that, just unplug your cam and crank sensors and crank it for a couple seconds then you’re gtg
Wonder if they would make that 3 second statement about a motor.
Smart commenter here;
For anyone who wants a mildly deeper thought on the dimpling,
The dimples on a golf ball do 2 things: reduce drag and generate lift.
First, to explain *pressure drag*. Basically, when you move an object through the air, the air in front of the object compresses, and the air behind it expands. The combination of the vacuum behind the object and the high pressure area in front of the object both try to move it opposite of its direction of movement, slowing it down. This is drag. (Quick fun fact, air friction barely exists in terms of effecting macro scaled objects. Like, it is so nearly negligible it’s almost not ever worth talking about until you get into rocket science. Most things we know as due to air friction like rockets re-entering the atmosphere heating up is actually due to air pressure.) when you make something “aerodynamic”, you reduce the negative pressure area behind the object by extending the high pressure zone as far as possible, reducing the negative pressure, meaning you only have to fight against the positive pressure.
The 2nd factor, lift, is due to air pressure above the ball being less than below the ball, dragging the ball upwards slightly, and giving it more height. This is usually achieved by making the air above the object move faster, meaning less of it is there, while gathering air under the object by slowing it down.
So in an air intake, you do not have that negative pressure zone that needs to be eliminated. Additionally, you don’t have ANY need to generate lift. Therefor, there is 0 reason to dimple the surface, and the mechanics that make it work on golf balls will work against air flow in this case.

Damn, had me laughing. I grew up in Sounthern California, hispanic dude was the man. You definately made me a bit homesick. Thanks
I spent my career working on truck and bus garages. The correct way to prime a turbo is to pump fresh clean engine oil directly into the oil inlet port of the turbo then install the oil feed line to the turbo and turn over the engine with the starter. If you delay the firing of the engine until the oil pressure comes up there will be no damage to the turbo bearings. Then fire the engine as normal.

Those wires were also way to thin to handle that current that was running through them, and would be even if they were connected in the right polarity.
That's why you should use wires that are capable of handle 350-400 Amps (2 AWG or 35 mm²) on cars to be on the safe side, as a flat battery will draw a huge amount of current from the other car, and even more when you try to start the dead car.
When cables are going hot, they starts to turn into a resistor that will consume power rather than deliver power.
So the the dead car is probably fine as those jumpstart wires are too weak to give enough power to destroy it.
I like that the dudes are like "yeah send it" on some of the hacks and the girls like "nah don't do that, it risks damage".
My dad is the only man I know who worries about doing it right and minimizing damage. Both of my brothers are of the "Fuck It" variety. 😂
Something Something Why Do Women Live Longer Than Men 🤔
The dudes been doing that shit everyday🤣. Id trust that street knowledge over any book smart
Because they understood the point of the video and she did not.
Truthfully I trust the girl to work on my car over the others. Her main focus seems to be not just doing the repairs but also not causing additional damage or costs in the process. Even when she said a hack would work she said it was a bad idea because it could cause the customer additional costs.
LOL good luck.

@@KingKablooie They mean they're one of those idiots stuck in the 1950s that think that women are incapable of doing anything outside of a kitchen. Don't worry, the world is leaving these morons behind.
I think she is good at explaining partially because she also works as a teacher at a college
@Tom_Tom_Klondike For me I just liked how she was really focused on not causing more damage that would need repairs. Some mechanics don't worry about breaking stuff while working because they can sell you parts and service for that and you never even know they caused it. I have run into a few shady mechanics in my day.
Dimples do improve aero dynamics. Dimples create basically an envelop of air around the golfball, air slips over air better than it slips over a smooth surface. With an intake the dimples may create a fast moving channel of air through the center of the intake, but the layer of air around the outside may decrease overall volume going through the intake. Golf ball moving through open air, and amount of air traveling through a tube are different. But I don't truly know this. I just have a high school diploma, common sense, and a lifetime of mistakes!! 🤣 @Donut I love y'all!!
Yep, I learned the screwdriver trick in the 60's before electric power tools. You are less likely to strip if you use the proper phillips driver. Since electric drivers, my hammer impact tool has remained in the tool box *mostly* unused. (That tool was necessary for motorcycles.)
The second one is solved by a tool called an "Impact Screwdriver". You hit the butt of the handle with a hammer and it converts the impact into twisting the shank of the driver. That way you fully seat the bit into the screw so you don't round out the head trying to get it out.
I think the overall takeaway from these videos is that TikTok and other social media can be a really good way to share car knowledge, but it's only really useful as a source if you *already know what you're doing* well enough to tell which advice to throw away. I think everyone in this video learned something new, but it was always a new application of knowledge they already had, and they knew what was trash because it was obvious from their experience.
Stay away from those cables at 11:10, shes right, you won't die, but you won't forget it 🤣 I had the throttle stick on a YZ250 when I was a kid, reached down the pull the HT lead to kill the engine, got zapped about 500 times in the space of 3 seconds.
Don't touch the spicy red noodles.
i remember when i was back in vocational college, someone had put the terminals backwards on a bmw 3 series touring (08 plate) and no one noticed until we were back in the shop the next day and the whole place reeked of burnt wiring, luckily the battery was basically dead anyway so it diddnt set anything on fire before it ran out of power

I feel like having car knowledge is one of the biggest flexes nowadays
It's just your insecurity
@@andrew348 lmaooo what, this generation doesn’t know shit about cars that’s why they get ripped off by mechanics. Dudes my age can’t even change their own oil or change a tire smh

@@CodyCopper04 You ain't wrong...Only thing it seems to do for me is disappear my weekends because my relatives are a bunch of cheap fucks and do not, or can not buy something that will reliably point A to point B
I've gotten laid just cause I knew how to change oil at half off. Be proud.
Dimpling the intake creates slight turbulence along the walls of the intake to prevent fuel dropout. Fuel dropout is when warm fuel vapour condenses on the cooler metal intake, liquid fuel "drops out" of the air fuel mixture. Carburetor things.
Not a hack. That's exactly why some screwdriver handles are hex shaped.
On the subject of that power-balance test, in piston-engined aircraft, we do essentially this test before every flight (although checking for the operation of the magnetos and the spark-plugs rather than individual cylinders) and we have switches in the cockpit to accomplish it. Flicking the switch grounds out the P-lead. Just as the good lady says, we are looking for a drop in revs (and to check that the engine continues to run smoothly).
I would love to see a vid with old school mechanics proving tips and tricks they learned over the years and have the new school rate them. Some of those old school techs are worth their weight in gold when it comes to mechanical knowledge.
Scotty or whatever and car wizard are good. There's also a ford guy that rebuilds triton engines and stuff. Shows how awful they are. Ford mak* something
It’s true but man them old mechanics can get you into trouble too cause the old ways aren’t always the best and they’re just stubborn 😂😂
@Raburn which is why I'd love to see the vid i mentioned.
@@RaburnTPF0297 But some of us realize there are changes and we keep up with them...I'd never trust a younger "ACE mechanic" with an electrical problem. Most of them have zero clue about how an electrical signal flows within the components.
I remember watching a video from the 1930's about auto racing and the guy checked for misfires by literally slapping the exhaust manifolds with a wet hand looking for hotspots. Was interesting but don't think you can do that nowadays lol
Not Priming the oil into a turbo makes a difference if you are keeping the car a long time and do a lot of oil changes those 3-5 seconds without oil on startup add up to damage over 250-400,000km and kill turbo. Oil change every 5,000km over 250,000km = 50 oil changes Times 4 Seconds = 3.3 Minutes of running without oil in the turbo. (No different to letting it run 3 minutes non stop without oil)
Modern Turbos are built to last, 350-500,000KM without failing.
So if your dies in less than atleast 250,000km it was YOUR Fault.
"I pee myself a little bit every day, and I'm doing just fine!" 😂🤣
From a body technician's perspective, I find it quite interesting how they pulled the camera away before they showed all of the little dents being removed with the ball, then cut back to the panel after it was nice and smooth. There had to be some light hammer work at a minimum to make that as smooth as it was.
Or they filmed it before denting it...
Yes! There was a couple little dings in the metal with the 'before'... and the 'after' was as smooth as new.... no way that happened as shown lol
the intake dimpling is best used for carburetor. Helps fuel to mix with the air better. Would not benifit as much, deffinatly mixing the fuel and air good. Ive always swirl ported the intake runners. If you polish the intake runner, the gas will bead up and drip causing inconsistant fuel mixture. Fuel injection is way different. Still swirl or dimple the intake runners on the head. But keep the intake smooth up to a little before the injector. Never polish the intake runner unless on a diesel with air fuel mixture isnt a thing
The finger imprint trick- factory workers back in like WW2 times would do that to check their rivets in hard to reach/hard to see places.
Using an imprint on the finger to match tool size is interesting but as said the imprint doesn't usually last long. However a trick I use is using a small chunk of blutack instead to get an impression - I always have blutack around the place, damn useful stuff for lots of useful little "hacks". . .
The blutack is probably an improvement, yeah, but I bet I can improve that further. There are non-drying modelling clays out there. Try a small lump of that stuff. It wouldn't want to stick the way blutack does. Cheap too.
@@ColonelSandersLite Yeah modelling clay works too. I like the tack because unless you leave it on for a few minutes it doesn't really stick at all, it just isn't strong enough. I've had the same 0.5 " ball in my toolbox for about 15 years. It never really dries out, when it is left for a while it gets a bit more solid but you knead it for a minute or so and it goes back to pliable. If it gets dirty you just knead it for a while and the dirt goes onto your hands and you just wash your hands. Also have another ball next to my solder station to gently hold stuff in place too small or delicate for a vise/clamp - like I said loads of diy uses lol
Alternatively, get an inkblotter like police use for fingerprinting, get the imprint, dip in the ink, press on paper. An accurate impression that stays.
In an emergency motor oil would also probably work.
So jazzed to see "in the crowd James"!!! I've missed him!
Nearly shocked the ever loving shit out of myself jumping a car like that, somebody else put the cables on the other car and I didn't know.
Golf ball effect, it creates an air pocket and allowes for volumetric efficiency but you realize the golf ball curves because of the dimples in the air so waste of time but looks cool. Polished is proven to disperse heat and flow better. Even in the intake side. And on a turbo car it’s essential for power
14:48 “yeah, and they hired the wrong guy to do that sh**” lmao😂😂
7:30 I used to work at an autoparts store, I told a customer to make an imprint of a bolt by pressing a piece of paper against the head so he knows what size socket he needed, and they came in with an imprinted piece of bread lol
Hey if it works it works.
It’s funnier to me that you don’t know sizes either and you work in an auto parts store. Ever heard of measuring tape? Also you can find out with your fancy computer. Yea I worked auto parts too in my past life.
@@Mordorer lol how am I supposed to tell a customer what size etorx socket he needs over the phone? Our computers didn't list bolt sizes.
@@BizarroStormy my apologies then.
The reason why a golf ball is dimpled is to cause the airflow to leave the surface more easily on the lee/downstream side. It's a known aerodynamic effect, where an object that's a bit too blunt at its rear is better to have the flow separated a bit earlier, where the object is larger, than to have the airflow continue further around the rear of the object, because the resultant eddies would cause more drag than forcing the flow to separate early. A golf ball is essentially spherical, which is aerodynamically poor, and it can be oriented at any angle, so it's dimpled all over to ensure that the flow leaves it reasonably quickly at all times. There was a Russian fighter jet in the cold war that had similar dimpling near the back to make the airflow leave the fuselage and reduce drag. For whatever reason, the aircraft had to be short, which made the rear section cut inward more tightly than ideal, so dimpling was added to get better airflow separation and reduce drag. However, if it were possible to make the fuselage longer and more sleek, that would've worked even better.
For what looked like an intake runner that was steadily curved, this dimpling is completely unnecessary because the flow is trapped and it has to change direction through its largely constant cross-section. The dimpling would only be beneficial where the intake tract opens up, and only on the lee-side of a bulge, but the idea for the intake is to angle the flow so it goes through the intake valve(s) nearly perpendicular to the valve stem, so the only place where there might, in theory, be any benefit is just inside the combustion chamber (dimpling there would be bad for valve sealing and combustion deposits, so that's a no-go zone), or if the port can't be opened up enough at the valve guide(s), on the lee-side of that. However, better intake geometry would work considerably better. In the intake runner, where there's a constant cross-section, dimpling won't help because it will cause turbulent flow. Through that area, it's better to make the surface smooth.
Dimpling works on a golf ball by inducing turbulent flow, which follows the curve of the ball better which reduces pressure drag. This increases skin friction, but overall drag is lower.
In pipe flow dimples would increase the size of the boundry layer, reducing the effective diameter of the pipe and reducing air flow.
He was so impressed with himself when he said "bread-press" lol was cute
