- čas přidán 4. 07. 2017
- In this video I will explain to you why you have a variable valve timing system on your car. But not just that I will also show you how it exactly works and operates. Some of the more common known variable valve timing systems are Vtec, VVT, VTVT and VVTi. All these systems work very similar to one another and I am going to explain it in this video.

Very good explanation of variable valve timing and how it works. I'm old school, worked on engine rebuild in the days of 4-bbl carbs and no pollution control baggage. Trying to learn and understand the newer technology and how it works. We've definitely come a long way in engine design. Thank so much for this video. A combination of theory, drawings, real engine parts, and explanation is an invaluable tool for teaching which helps everything you discussed make sense. Kind of remind me of my instructors I had when I took auto mechanics trade school in the early '70s. They used the same instruction methods which works well. Bravo.
The "5-stroke" joke you made in the first minute of the video was legendary by the way.
I really like the way you break it down, simple and uncomplicated. The average person can get clear information without a degree in engineering. Thank you very much!
Ive been trying to understand VVT and how its achieved through oil pressure. This video is perfect in explaining how and why. I particularly enjoy the humor interjected. Well done in all aspects. I subscribed.
Your explanation of how VVT works , and how it is employed in effecting Exhaust Gas Retention internally ( as opposed to Exhaust Gas Recirculation which requires separate externally installed valve in older engines ) , to me is the highlight of this video .
Keep up with the good work!
respected worker n teacher, we support you👍
Totally agree with the title.."variable valve timing explained - like never before". Glad you got more space to make more videos!!
You are a very good teacher and mechanic
Thank You for taking the time to explain how it works! Its so hard to find the correct information and application! I truly enjoy your videos!
Love these videos. I finally understand a little about this valve timing thing. Thanks, Ratchet. You're a real pro.
How is this not the #1 educational channel on youtube yet?
Beautiful explanation. Perfect balance of theory and real-world visual examples.
Woah, now I understand! I replaced my intake & exhaust VVT solenoids on 2017 GMC Terrain at only 43k miles. Intake side was filthy!! My oil has been changed by the dealership regularly so I’m kinda upset at what I seen on the solenoid. Now it runs great again and no longer stalling. Thank God for CZcams because it has helped so much!
From 8m 30s, the Ecotec VVT explanation was just terrific.
Old timer here and now I understand about this variable valve timing. Excellent job explaining! Congrats. on the new move and hope it's saving you some money. You have some of the best videos out there on fixing cars. My first car was a 1960 180b Mercedes and those weren't the fastest cars but what a dream to work on. None of this computerized stuff. So that was back in 69 and have been working on my own cars ever since. Unfortunately all of the injuries have caught up on me and it's getting to painful to do the work although it's been so rewarding being able to be self sufficient! So lately I've been looking at Lexus' and from what I can tell they seem to be the best built cars out there. Would love to here your thoughts. Thanks and keep up the good work.
Thank you for explaining the vvt. I like the board holding the hood up & two less flies to breed. Keep up the good work.
That is a very very good explanation on vvt. Wish everyone could show stuff so clear.
Lol I love the little comedic parts of your videos. Keep it up!
This video is so explicit and for dummies ....thank you for your effort !
This guy is too quiet and patient ... I like listening to him, good job, man!
Very educational...now I know how the VVTS works! Good production, good enunciation! Thanks
Your content keeps getting better and better. Good stuff dude. Congrats!! - Saludos
Glad you like the video, thanks for commenting.
Awesome explanation of VVTI, thank you very much Imon.
New viewer and sub here! So living on my own and now having to do work on my own for vehicles, I had my first engine indicator come on. Wanting to learn to do things on my own, got myself a bluetooth obd2 reader and app. Now I am learning about what the part I will be fixing has to do with how my car works. This is leading me into a rabbit hole of education on, well put honestly, how vehicles work :) And this so far is what led me to your content and I love how you present things :D
Great explanation. Wish you all the best in your new place and look forward to more videos.
I'm glad your still doing what I like to see. And your a good 👍 at what you do. In explaining and making us understand the difference thanks 😊
Best VVT explanation I've ever encountered on youtube. Thanks!
Yeah, he did a better job of it, than I did.
Glad you like the explanation, thanks for commenting.
Very well laid out- super job!
Good luck, and thanks for your videos and explanations. Keep'em coming.
This video was fantastic! Thanks for the great explanation
Very helpful. I was looking for someone to explain this. Thanks
What a fly episode. I like the way you explain things.
Thanks for the videos you make, it’s so easy to understand
Outstanding job buddy, keep up the hard work it's greatly appreciated🙂
Your the best at explaining theory and practical mechanics. Congratulations on the new house and shop. I always enjoy your videos. If by moving there means it will make it easier for you to make videos then your right, it's a win, win, and maybe another win indeed.
But darn, still no money shot. lol
Thanks, yes its pretty convenient if you can get out of bed and walk into your work haha so it should help with more video's.
haha
Damn CZcams be bringing in that cheddar 🧀 = 💵💵
Enjoy your videos, and your humor!
I enjoy your videos”very knowledgeable.specific! Straight to the point keep it up
Great video. I love how you always explain some of the more seemly mysterious automotive theories into ways people can understand. Congrats on your new combo house workshop. Its so nice to see people stand up to landlords who are always trying to raise rents on good tenants. Im proud of u.
Thank you, I was kind of ready for him. I keep my business lean and mean. Can pack up and leave within weeks and not lose much in the move.
You thinking there are people coming to look for you ? I guess ya better be ready to fly (oh oops don't do that you might get smacked by a pizza box..)
Very informative - thanks for making this!
Thank you for this video. Very clear and helpful.
Awesome video bro. Congrats on the new house too!
Great job explaining a very good part to learn for future uses to repair automobiles
Great explaining! Thank you
Excellent explanation. These were always very mysterious to me. Thanks for clearing it up!
np, glad you liked it. cheers
Awesome explanation of components. 👍
Nice explanation. Love the hood prop.
Thank you.I have this engine in my Aveo 2010.I will clean my cam position solenoids and hopefully cure my intermittent acceleration(bucking)problem.I did not know the exact theory behind the variable timing but your explanation was right to the point.Thanks again
Well I replaced both Advance timing solenoid, and it did not fix the car
A clever system indeed, thanks for explaining 👍🏻
You explain it so well. Wish I could be your apprentice 😎
I understood exactly what you just explained. Thank you..
Very in-depth, keep up the great work!!!
Glad you like the video, thanks for commenting.
Great explanation! Thank you
Your doing a great job explaining how it works ty
This VVT system always seemed more complicated than it needed to be, and the dependence on extra solenoids and motor oil moving down narrow channels made me wonder how long they would last. However it seems like these systems are holding up fine, so far. Even better reason to change motor oil frequently, ha ha. Good video, welcome to the new shop!
I was wondering about a fail safe if the solenoids stopped working all together as solenoids have been known to do.
Yes, they are pretty reliable now. But yes frequent oil changes with these setups is crucial. cheers
The solenoid is usually spring loaded inside where if it were to fail t will go to a position where there wont be any damage, either valve to valve or valve to piston. cheers
Like to know where the VVT Filter Screen is on a 3.3L 2006 Sienna - better to clean that first than go replacing things that might not need replacing.. although I am sure after 200K or more they might be a bit more gummy than a bear.
Stix just get the solenoids you cheap bastard
Always wondered about how this works. Thank you for the info.
Your videos beat any money shot!
I enjoy the videos. ..
since my specialization is pre- 80s resto-mods, you provide me with good info on the newer garbage that I'm forced to work on from time to time.
Glad you find them helpful, thanks for commenting.
It's a comment to help this channel grow.
thanks for your precious time, very informative, good luck
As usual, excellent video. I always wondered about how variable valve timing worked.
Glad you like the video, thanks for commenting.
Great review!! Every detailed
Thanks for that great explanation!
Thank you for your nice video.
Good luck with all your work no matter which one of four above engine moves you do.
What a pro explanation, thank you
Excellent 👍 explanation. As good as the GM technical videos of the 30s. Thanks.
Congratulation to your new house and shop.... I really enjoy watching your video and learned a lot.
Excellent video. Absolutely helpful. Thanks.
Love your videos. Lots of info.
Great video!! Awesome details.
Man good job on explanation of that really hit home and I understand much more clearly now thank you
very educative. thank you regards
Your really easy to like,great job an good luck. Love the dog !
Excellent Video....
Your engine looks similar, if not identical, to my Chevy Sonic 1.8L LUW. I just replaced my head gasket and also ground the valves, removed tonnes of carbon buildup on the exhaust valves and Pistons. Great video. Now I know why I don't have an EGR valve. The LWE 1.8L carries an air pump. Just before putting my head back on, one of my dog was not feeling well that day and vomited on the head, wiped it out but I am guessing the oil filter and PCV system should rid the rest of it 😂😂😂
Thanks for the great vids and keep up the good job !!
Thanks man. Good job.
Excellent job - thanks
Those flies were watching you repair the car. Flies don't know much about modern cars but they are learning.
Great video thx helped a lot
Thanks, that was a great explanation
Hello, thanks for your video, I disconnected the MAF and the car idles low, it does not go up more than 500 rpm's and the brake is a bit hard, although the fault disappears where the ralenti is 2000 rpm's and the brakes stop oscillating RPM's from 1000 to 2000, you can't drive. I bought a stock MAF like the one you have factory at Toyota and it didn't fix itself. I thought like you about the leak and had the servo checked and they told me it was fine. Take out the intake manifold and seal some joints that seemed not well sealed. Another test that I did was to disconnect the brake booster valve and the rpm's also drop to 500 rpm's, the brake remains hard without the help, you can't drive like that either. I will also tell you that we removed the throttle body and it was submerged in special liquids, no dirt came out, the car in general is very careful, the only thing I could not remove is the IAC valve because it has a special 25 Pentalobe type key I think, but I can't buy that tool, the same thing, both the IAC and the TPS were cleaned and measured with a tester and the injector voltage was checked and it works fine. I also changed the intake manifold gasket, spark plugs and PSV valve, all original Toyota, the Toyota scanner and other colleagues say nothing of failure. I put a vacuum gauge and it measures 18 normal psi and when accelerating it drops to 0 and then recovers. I don't know whether to suspect a leak from injectors, I am very disoriented and worse, I live in a very small city far from any official service to take to the car and no one has a vacuum gauge and has smoke to see where the leak could be. If you can think of a control that you can do, I would appreciate it. Greetings
Nice and clean garage shop.
tyty
Great Video....Keep it up...Thanks
Goodluck with your new workshop plus home bro......It seems this place was much better than earlier place....
Good explanation
Nice video, l like your explanation
You explain well. Thank U.
Great vid bro
Smart man greetings for you from Iraq
Great video and smart move.
Hella VTEC, yo!
Hahaha that made my day bro
Very well done. EDUTAINMENT!
Good for you!! Its sad how people are getting so greedy but it always comes back to them. You get back what you put out
Awwwe I love that “butthead” and that’s an awesome idea. You thought of getting that house with the two part garage. Love your videos. Thanks for sharing. ✌🏽
Great explanation!
great video!
good video ---thanks---keep it up.
Seriously and isn't it good to see some with ratchets on hand, actually know about Engine!🤓😎👌🙏
EXCELLENT VIDEO THANKS VERY MUCH!
np, glad you liked it. cheers
Thanks for the explanation. Fighting a rough idle at stopping, on a Corolla 1.8. Gonna try cleaning them first. But at 37$ might just replace at 250k miles.
