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 TH-cam because it has helped so 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.
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.
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!
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!
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.
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!
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.
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.
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..)
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.
I had fault code P1007 and P1014 on Peugeot 207 car could not start I just cleaned it and bingo it started again. Be careful the symptom initially looks like a fuel problem, don’t replace your fuel pump just yet. Thanks for the video!
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
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.
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
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
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. ✌🏽
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.

The "5-stroke" joke you made in the first minute of the video was legendary by the way.
How is this not the #1 educational channel on youtube yet?

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!
This video is so explicit and for dummies ....thank you for your effort !
Beautiful explanation. Perfect balance of theory and real-world visual examples.
Totally agree with the title.."variable valve timing explained - like never before". Glad you got more space to make more videos!!
Your content keeps getting better and better. Good stuff dude. Congrats!! - Saludos
Glad you like the video, thanks for commenting.
That is a very very good explanation on vvt. Wish everyone could show stuff so clear.
Love these videos. I finally understand a little about this valve timing thing. Thanks, Ratchet. You're a real pro.

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

Stix just get the solenoids you cheap bastard
From 8m 30s, the Ecotec VVT explanation was just terrific.
This guy is too quiet and patient ... I like listening to him, good job, man!
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.
Lol I love the little comedic parts of your videos. 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..)
You are a very good teacher and mechanic

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 TH-cam be bringing in that cheddar 🧀 = 💵💵
Thank you for explaining the vvt. I like the board holding the hood up & two less flies to breed. Keep up the good work.
Your videos beat any money shot!
Very educational...now I know how the VVTS works! Good production, good enunciation! Thanks
Great video, really informative, I had a basic idea of the concept of VVT but lived actually seeing the oils paths 👍 love the dog too!
Very helpful. I was looking for someone to explain this. Thanks
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 😊
You explain it so well. Wish I could be your apprentice 😎
As usual, excellent video. I always wondered about how variable valve timing worked.
Glad you like the video, thanks for commenting.
Excellent explanation. These were always very mysterious to me. Thanks for clearing it up!
np, glad you liked it. cheers
What a fly episode. I like the way you explain things.
Enjoy your videos, and your humor!
Thank you for your nice video.
Good luck with all your work no matter which one of four above engine moves you do.
Smart man greetings for you from Iraq

Well I replaced both Advance timing solenoid, and it did not fix the car
Excellent 👍 explanation. As good as the GM technical videos of the 30s. Thanks.
I enjoy your videos”very knowledgeable.specific! Straight to the point keep it up
Awesome explanation of VVTI, thank you very much Imon.
Butthead is a good boy. Love your videos. Thanks
Great job explaining a very good part to learn for future uses to repair automobiles
Thank you for the video! I think all educative videos should be like this!
Thanks for the videos you make, it’s so easy to understand
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.

Love your videos. Lots of info.
Your really easy to like,great job an good luck. Love the dog !
Those flies were watching you repair the car. Flies don't know much about modern cars but they are learning.
Great explanation! Fascinating. Thanks.
Silute.. love your explanations.. good teacher
very good video
Great review!! Every detailed
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.
Great Video....Keep it up...Thanks
EXCELLENT VIDEO THANKS VERY MUCH!
np, glad you liked it. cheers
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
Thanks you very much for teach more video
