1. Thank you for saying "Porsch"(ah)

2. The dude in a white shirt and black donut baseball looks so much like the actor from the Invisible Man series, I really liked that show when I was a kid😊

3. The bushing has a metal housing so drilling out the rubber won’t affect the inner diameter of the hole.
   That’s a good hack for stuck bushings.

4. I got a Donut ad watching a Donut vid 😭

5. Girl mechanics @ 😍

6. Counter balance testing only drops rpm for half a second
   The computer is going to compensate and keep the idle set. If your idle is 650 rpm you can kill 3 cylinders and idle will stay at 650 rpm

7. How in the fuck does a room full of mechanics not know the finger print trick? Being doing this with allens, torx, and reg bolt heads for decades, and I learned it from an old mechanic when I was young lol

8. 1:35

9. You keep saying water is better than oil…. If you're going to test valves the way they did in the video, then water is fine. Otherwise you can actually see the water as they're pouring it why water is NOT better to see if it seeps through… the water has a LOT of surface tension and won't seep through on an oily surface. The OG way (as it's been for decades) is to use something like kerosene, diesel, or even brake cleaner. Hell, you could see the water just beading on the top of the valves and wouldn't seep through the valve seat gap they discovered. But again, if you're using air, then water is fine. Just don't bother looking in the ports to see if it leaked through…. it would have to be pretty bad if water could get through even a bad valve seat 😛

10. That golf pattern skin is to create better mist petroleum flow especially for 2 stroke carburators… Many drag racing do that method in Asian

11. So the guy who put pressure back into the spray can, theres no need to do that.

    First, try squashing the can a bit to create some pressure. If theres no pressure at all then just cut the can open and either pour it into a spray bottle or a jar and use it however you want.

13. Use a razor knife to cut the old grommet out. Only needs one cut long point to long point. And peel it out….🤔🫡❤😂🎉

14. 5:00 Regarding the breaks… I remember that once with my friends going on a spontaneous 300 km trip at 3am and after the first 100 and some, my friend who was driving it, stopped the car, open the hood and when I went there he said… I can't break good enough and feel that I'm loosing it… Then he told me that he usually drive with his girlfriend so nobody in the back.

    Now, that we were 5 in the car, the back brakes switched on and something is not working. So he was canceling those that don't work and use just the other ones (I'm not a mechanic and I don't remember which ones, but I suppose the ones from the back…).

    And on our trip, we had some challenges. We had some time driving uphill, he had to stop from time to time and when he stopped some steam will rise from below the car 🙂 Then when we got back, the same downhill. But the trip was awesome so cheers to him to knowing what is happening before things got worse and also for what he did to make good breaks for a while.

    I don't know how risky it was, but I suppose everything is risky when things don't work as they should do.
    But I know that I will not drive in that condition on that road ever, except if it will be the only way to do it. Otherwise I will go back, repair and make the trip another time.

    Few days ago, some young people died because of the driver wanting to test the new care he bought 3 days earlier when they went in the mountains and the car fell at least 200m into the… hollow. Not so much experience with that car, but he tested with another people in it… And 3 died, one lived… Is it worth it? No.

    People, please make risky choices on your behalf, not playing with others lives.

15. 60000 volts?! What are you talking about its a 12 volt battery 😆

16. 9:49 nope, The Mythbusters proved, it improves airflow

17. Red on red and black on black doesn't always work- check your cables! Customer brought in a car where they had replaced the battery cables and made the positive black and the negative red. Replaced the battery for them and wasn't paying attention and fried a bunch of stuff….

18. dont trust tiktok, trust the forums

19. James is so damn annoying bro

20. probably have the negative and positive crossed….13:24……probably…. but if you use absolute units of wires as you should. you can swap them however you want and that will never happen. but well….i`m not a mechanic. sorry. real mechanic.14:15 red on red black on black. solid advice. but if your cables can`t take the amperage, even if you connect them correctly they still melt. look for the gauge of the cable.15:28 use a ball to pop a dent. strip the door and stick a ball and inflate it to pop a dent. i honestly would use a suction cup on the outside first before creating a lot of labor dismantling the inside of the door.

21. I'm curious about the dimples. I know golf balls have this for air flow. I think Smooth is better, too. But it would be a cool experiment to see if that actually worked

    Golf ball dimples are designed to improve aerodynamics and enable the ball to travel farther and more accurately. Dimples create a thin layer of turbulent airflow around the ball, reducing drag and allowing for a longer, more stable flight. This turbulent flow, caused by the dimples, helps the airflow to stay attached to the ball's surface for a longer distance, resulting in a smaller wake and less resistance.

22. Ads in your show is b.s.

23. 15:39 that’s smort

24. The dimples in the air intake.
    The dimples in the runner are for creating more turbulence in the runner to prevent the fuel droplets from falling out of the air when it travels along the walls of the intake, polishing intake runners actually make less power due to poor atomisation and fuel wetting the side walls of the intake and ruining the mixture ratio. Never polish your intake a normal rough factory finish is good but this dimples seem excessive the only real way to tell will be a flow bench and dyno tests. Polish the exhaust ports and combustion chamber yes but inlet no. Golf balls fly further and faster if they have dimples compared to smooth ones so there might be a bonus.

25. They missed the jumper cables being to a household product so the problem is the wire isn't thick enough, but it would potentially let you start a car

26. Intake port shouldn't be perfectly smooth. I've match ported motorcycles for years… Building hill climbers. Exhaust polished. Intake rough keeps fuel from forming droplets… Atomizing better.

27. "most car companies are pretty good at getting air" … me looking at Cummins 👀

28. Me and my dad just guess the size and we are mostly right

29. There is real science behind the dimpling of the intake. It actually has lower friction -however that car likley delivers what the car needs so thats a lot of work for something giving limited gains

30. I watch these to remember why I don't miss my old career.

31. #2 isn't really a hack, its designed for that exact purpose, thats just using a tool as designed, but less and less people are aware of that feature

32. I can’t get over how beautiful that female mechanic is. I wanna meet her actually I’d marry her.

33. Whoever that girl is, she’s really beautiful

34. Where is that can a dollar. I need to buy all of them

35. Too bad your mechanics only know half what they need to comment on these "hacks".

36. I don't know if I'm too late to do it or if im doing it wrong but I was calling around and they was telling me I have to pay $25 Grand unless I was already with the dealership that sponsors me if someone knows what they're doing please help lmao

37. 12:15 iknow why they only got her clip an nobody else for that one

38. 6:00. Congratulations you just turned a $1 spray can into a claymore antipersonel mine.

39. Spray can hack would be good for the hobbist not professionally maybe 😂

40. 9:11 On port injection engines. You want some turbulent air to help mix the fuel and air before entering the cylinder. So port and polish before the injector and port only after. The rough cast wall and some texture from the porting process help create a little turbulence. As far as the gulf ball texture IDFK.

41. You guys should stop. Seriously. How else is the rest of us gonna get rid of the stupid if they can't take themselves out due to decent humans being… well decent. Stupid is suppose to have a hard price… that's the point. Protecting them has only ever limited the rest. Stop and help those who are truly decent people and let the morons go, they have but themselves to blaim anyways.

42. Yeah right! I took my 928 to the Porsche main dealer in Nottingham, England. They didn't have a clue how to work on it. Eventually I took it to a 928 specialist and he fixed it withing ten minutes. There were two relays to start the vehicle and one had died.

43. When I jump someones car, i dont let them touch the cables cause people are STUPID
