Everything about Engine Valves

[@GreenZinfidel]

As others have said, the quality of education and delivery in this video is just unrivaled. You are an excellent teacher and I've learned a lot!

[@elessal]

DO NOT PAY FOR THIS! it may not have started as a scam but now it is for sure! if you check social media, you will find a lot of people who ask for help and were ignored by this guy. in a few weeks the site forgot I bought the course and even if I am loged it it won't let me watch videos, offering me instead to buy the course again. no one responds emails nor messages sent to the social media profiles. also, the course is incomplete and this guy has not uploaded anything in years. and none of the site-only videos were is 4k as promised. only the free youtube ones were. there is not even an option to download the videos, so unless you know of a hackey way to do so, don't bother giving money for this. if someone finds a way to download the videos, please upload them to the pirate bay. despite all, the videos were actually quite good.

[@bestfix7160]

Unbeatable quality and thoughtfulness.

[@abdulmoen]

Why not have one large pair of valves per cylinder instead of multiple pair of valves

[@op-tim_auto]

@@abdulmoen because of the geometry.. four holes side by side gives more diameter area then two big ones in a given space.

[@daviderhahon]

Yeah No nonsense.

[@dawoodmsaleem606]

No more bullshit talk no intro music no head ace music nothing simple and lovely way to teach us 😉

[@daviderhahon]

Simply put, No Nonsense...

[@GiantsquidSquid]

I agree, to bad he hasn't uploaded in months I am doing my automotive service technician fundamentals course and this video I feel the way he explains it is way better than most of the channels I find when I'm looking up specific things

[@mariospera3282]

This channel is worth many more views and subs

[@WigoRaizeTV]

I'm just wondering why this channel do not make videos anymore.

[@addkahaddkahaddkah7257]

After 6 years of posting this video, thank you🎉

[@kanokponkruasarn4901]

High quality video! Straight forward, easy to understand and no background music.

[@HC-ov2hh]

I must say my new friend you have the best channel for learning about the mechanics of automobiles. Thank you!!

[@aniketsangewar3380]

best quality knowledge I have ever seen on youtube...each video shares in depth knowledge about the topic which is generally not captured in reading a book. pls continue to share such quality content

[@cjwise5552]

I’ve watched two videos and I’m sold. You’re the guy everyone needs to learn from. This is amazing content. Didn’t miss anything at all or leave anything out.

[@daviderhahon]

Interference engine and more.... So much shared knowledge beyond just engine valves. Thanks for the video.

[@jamescartwright387]

I sell car parts for a living and yet I still occasionally learn a thing or two from your videos. Fantastic work

[@VTECsqznN2O]

Omg thank you. I now understand why people say interference motors can get damaged when the timing components break. Very helpful.

[@ahmedbenmeddour6838]

One of the best videos about cars .. thank u

[@RoxusRemo]

From finding your channel 30 mins ago to buying your course, thanks Alex. Just what I was looking for!

[@elliot1784]

How to buy? Is it removed?

[@barbaduzas]

Bought your full course, cant wait to learn everything about my car!

[@ibreliohussein8040]

Where can I get the full course

[@BwanaLawi]

Totally worth it

[@MatthewM214]

I bought it but I can’t watch the videos

[@thomasmiddlebrooke1012]

A well done video. What's really annoying about interference engines is when they put rubber timing belts on them. Then when the break, you lose the engine because you didn't change out a $50 belt. This is why I'm glad that for the most part, a few good auto makers (Toyota, Ford and others) make non-interference engines with timing chains, or at least chains when they are interference engines.

[@raoras1104]

This is ridiculously high quality.

[@sumitmajumder9733]

Passion is visible by your teaching sense and knowledge

[@Алексей2077]

Лучший технический канал по теме ДВС! Без воды и ошибок в терминологии а так же четкий материал!

[@0501245]

The answer to my question came at 11:20. This channel is gold.

[@Adikxx]

This is the best youtube channel for car knowledge ! By far !

[@condor5635]

Great video - would have been nice to show the valve seals up close unless I missed it. I just replaced 16 seals on my 2003 Suburban. What a job that was! No more burning oil though! 243k and going strong. Thanks!

[@arbazgul2694]

so informative and in complete detail about valve. thanks man

[@japfourme381]

Excellent video mate clear & precise explanations as to how the valves work in a cylinder head!!

[@shuvachowdhury5040]

Your explanation style is far better than animated explanation.

[@elguapo1690]

I've never heard such a clear explanation of an interference engine. I've heard a few people half explain it.

The guy knows his stuff. The best I’ve seen so far

[@bobi_lopataru]

Thank you for showing how the valves fit in, I want to make a 4 stroke engine and I had some doubts to how to deal with the valves

[@ayo2437]

this is too good to be free on youtube!!! THANK YOU!!!

[@airmax90_king93]

This mans videos are truly amazing

[@chasesblog]

Got a 2014 Chevy Silverado that blew its engine back in October, 180k miles, and finally figured out last week a valve went out in the engine and apparently parts of the valve were found in the exhaust. When it went out on me it still drove for about a mile as I could safely get off the road if I didn’t stop immediately so I had that going for me as well as we were able to find an engine to replace it with. Decided to look more into valves and this video was interesting. Hopefully how I said that makes sense, I heard what caused it from my dad who is in contact with the guy that’s replacing the engine for us so I haven’t seen any of this myself.

[@albinlelievre3912]

Very clear and high quality vid and channel. if i may say something, you forgot to mention how the spring is keeping the valve closed. (caps and retainer...)

[@simbayoung4757]

I’m learning so much from this guy. I’m going start saving to pay for the full course. I Will definitely get my money’s worth

[@ajayattul5692]

Thank you for educating with lot depth visual clarity, just like valve guide how a valve fits in it

[@-Gargantua]

U r probably the best mechanic I know currently

[@DuddiPranav]

Not mechanic . He is an engineer

[@GetUpFalcon]

Just stumbled upon you after googling how water cooling works. Terrific stuff mate - as an Aussie I'd much rather listen to a Brit over an American and it's thrilling to now know there's one out there to listen to!!

[@Likeagoodnovel]

This is gold. So informative👌🏼 top notch quality

[@ml20101993]

Very high quality content, appreciate the effort behind this work. Thanks a lot man !

i am planning to be a car mechanic as i am related to completely different field, and yet i have my 5 hours watching your videos, now when i drive my car, i know how its moving

[@himprakashdas4482]

this is exactly the channel i was looking for...subbed

[@streetlight7444]

No ads?? For real?? This is the most worth watching channel

[@waynebreivogel1742]

Yet another outstanding presentation. THANK YOU!🙏 PLEASE... camshaft and cylinder head installation!

[@cesarbarrientos8089]

Your gazing upon a genius when tuned into this channel.

[@iamakramfaiz]

Please continue the series it's very helpful.😀

[@AliasTutorials]

Awesome videos! Production level is superb, informative and stunning! Thank you

[@jatoxo]

9:48 Won't the springs return back their potential energy as they slide against the other side of the cam, pushing it along?

[@massimilianoscarmin5970]

5:55 i think it's because exaust's gas has a greater pressure after the power stroke, so it can pass trought quickly.

[@mtzkidd]

These videos are really good. Information very accurate. However if you had an animator to animate your descriptions then this would be flawless.

[@KB-xc2rz]

Love it bro....please make more videos...on these parts....

[@Fireneedsair]

Wow! Just a GREAT presentation!

[@tylerhonch]

The dragging on the machined surface!!! Good video tho, learned somethings !

As said already. Brilliant, all round.

[@danielkraut6108]

Great video again, thank you

[@PoliticalGangster]

Wanted to see what a valve seat and valve seal and valve guide looks like. Damn you to an otherwise good explanations.

[@jmurphy1973]

10:50 The Hemi guys just went all giddy

[@prashantjoshi9374]

The intake valve is bigger than the exhaust valve because the pressure difference at the intake region is less (also mass flow rate less) than the pressure difference at the exhaust region(also mass flow rate more). But mass flow rates must be same for intake as well as exhaust (m(in) = m(out)) hence to satisfy this, the area of intake region should be bigger than the area of exhaust region.

[@polcommwatcher]

Very cool. I know as much about engines as a box turtle knows about The Who; learning about such an ubiquitous and important piece of machinery is quite satisfying. My curiosity is stoked primarily by interest in motor racing--when a book mentions 4-valve heads as an important aspect of engine development during the 1.5 liter F1 era, I want to know what that means. Alas, such knowledge doesn't keep me from fantasizing about racing a Lotus 33 at Spa, and degrading my own puny life experiences. Why aren't we satisfied with what we have?

[@ianvangiesen2523]

Great video! I have a question regarding valve float: does the ignition process in the combustion chamber provide any force that aids the spring in closing the valve stem and keeping it in contact with the follower? I'm doing some analysis on a cam-follower and valve-stem assembly, and it seems that the force needed to keep the valve in contact with the follower is extremely high (~10,000 lbf or ~44,000 N of force) much higher than is reasonable with springs that would fit in that area. Do you or any other viewers here have ideas or input on this?

[@mountainbeast116]

Thank you so much for this content🙏

[@Farseer1995]

Where would one find the video about the cylinder head?

[@germangedgauds7594]

Your doing premium content, thanks for that!

[@theepicyoutubization]

Dragging that head, face down across the table @ 2:51 made my brain fucking scream

[@paulzapodeanu9407]

In most engines the intake valve is also cooled by the air/fuel mixture.

[@BENNO117]

Air yes, fuel no. Most engines have direct injection.

[@thorthunder3227]

Did you mention how the length of the valves effect the performance of the combustion intake? Did you mention the stem height? You need to explain this for clarity because if you order some valves and they are not the same lenght but the diameter is the same then you will have a combution problem balance in the intake gases and the exhaust gas also. Explain it please.

[@TM-fx5le]

You problem?

[@larryhernandez5062]

Excellent teaching video . . . Thanks . Stay Frosty All

Hi, sorry for asking this! I want to find the name of a turbo-diesel engine (4 cylinders) that has 125ps/2600rpm? Could you help me? Thank you very much!

[@Jmoneyy365]

Can you do a video on timing belts and serpentine belts?

[@TheJoyOfGaming]

No fluff, cheers mate.

[@minamishail_Tech2024]

Can you make a series of videos about turbo engines & what is good & bad about it ?

[@onefasho]

Well explained bro, keep up the good work 👏

[@Anurag_Singh_Classes]

Amazed me by explanation .

[@MBicknell]

Brilliant guys. Liked!

[@pavankumargudla4000]

Bro you told in interference engine same space is used by value and piston right..! But how does exhaust takes place, because in exhaust when exhaust valve come down, the piston moves up to push gas out from the chamber through the exhaust value. So won't they collide then..?

[@BENNO117]

The exhaust valve starts closing as the piston goes up.

[@MrKirumbuyo]

Is there a way to examine/inspect the valves without tearing the engine away? I mean by inspecting its performance or some ex-ray etc? Ultimately, how do you know that you have a faulty valve? (Bent or one with its head burnt/destroyed?)

[@BENNO117]

A compression test is a good way, or a vacuum test

[@anthonyhope3350]

Nice video men in depth skills

[@JonnyD3ath]

2:07 this woodworking lead to nothing!? Lol

[@101perspective]

Lol... yeah, I was wondering the same thing.

[@ayo2437]

LOL

[@kingiburu2778]

I said to myself... That's not wood lol

[@SuperKinahead]

Why not make the valve the same material? Wouldnt that be better to have heat transferred along the stem as well as the head? instead of just having it all in one point. Sorry if i sound stupid, iv just started in automotive engineering, and just curious.

[@khalil1531]

Thank you for the helpful informations 👍🏻

[@erickrayos]

the "grinding" the valves is also known as "lapping" the valves right? just to make sure I know exactly what you were talking about.

[@maxhoonigan3757]

When you replace the valve do you have to brake it in slowly or can you just run it like normal??

[@edlopz1722]

Thank you !! another great video .....

[@abdulrahmanjumha7751]

Thank you for this video this is so useful

[@guilhermecish]

The head is usually made of stainless steel and body a chromium alloy steel, induction hardened on the tip.

[@matt3122]

Do the valves spin?

[@shravanpandey513]

where is situated in engine valve ??

[@bendude6748]

How bent does a valve need to be to cause no compression? I have a cylinder head that has compression issues but the valves look oddly straight which I wasnt expecting.

[@BENNO117]

A bent valve won't seat properly which means it won't seal allowing combustion to escape through the gap

[@bendude6748]

@@BENNO117 it turned out to be the hydraulic lifters not letting the valves shut properly valves were ok 👍🏻
