Variable Valve Timing Explained - Like Never Before

[@amclamb9543]

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 KZbin because it has helped so much!

[@ericspear3610]

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.

[@edwardmuhm867]

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!

[@davek4139]

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.

[@ohenenorb]

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!

[@pantheradesigns]

The "5-stroke" joke you made in the first minute of the video was legendary by the way.

[@DanzigerBridge]

How is this not the #1 educational channel on youtube yet?

[@d-s-ll2378]

respected worker n teacher, we support you👍

[@EartAlienEB1]

This video is so explicit and for dummies ....thank you for your effort !

[@dougdevine27]

Beautiful explanation. Perfect balance of theory and real-world visual examples.

[@ronmahoney175]

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!

[@Abu_al-rrub]

This guy is too quiet and patient ... I like listening to him, good job, man!

[@FrancisFurtak]

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.

[@spelunkerd]

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!

[@klopossa2]

I was wondering about a fail safe if the solenoids stopped working all together as solenoids have been known to do.

[@myRatchets]

Yes, they are pretty reliable now. But yes frequent oil changes with these setups is crucial. cheers

[@myRatchets]

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

[@stix562]

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.

[@JB-fm4tb]

Stix just get the solenoids you cheap bastard

[@enriqueatala2567]

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

[@MichaelGawesebmainone]

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!

[@NoahTheFacts]

From 8m 30s, the Ecotec VVT explanation was just terrific.

[@BryanChance]

Totally agree with the title.."variable valve timing explained - like never before". Glad you got more space to make more videos!!

[@aquablueoceans]

That is a very very good explanation on vvt. Wish everyone could show stuff so clear.

[@royalflush8173]

You are a very good teacher and mechanic

[@alancameron2433]

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

[@55ROLLO66]

Well I replaced both Advance timing solenoid, and it did not fix the car

[@jerryuptmor2826]

Love these videos. I finally understand a little about this valve timing thing. Thanks, Ratchet. You're a real pro.

[@davidraborn3654]

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.

[@rayjennings3637]

A difficult subject very well explained - especially without 3D graphics!

[@klwthe3rd]

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.

[@myRatchets]

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.

[@stix562]

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..)

[@j.gtheautotech8455]

You explain it so well. Wish I could be your apprentice 😎

[@williamcost8168]

Very educational...now I know how the VVTS works! Good production, good enunciation! Thanks

[@darwingrose6976]

Great job explaining a very good part to learn for future uses to repair automobiles

[@buzzpedrotti5401]

Excellent 👍 explanation. As good as the GM technical videos of the 30s. Thanks.

[@lewisbighuber7029]

Those flies were watching you repair the car. Flies don't know much about modern cars but they are learning.

[@FCAutos]

Your content keeps getting better and better. Good stuff dude. Congrats!! - Saludos

[@myRatchets]

Glad you like the video, thanks for commenting.

[@manuelaguero1296]

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 😊

[@mikeautostudent5562]

Thank you for your nice video. Good luck with all your work no matter which one of four above engine moves you do.

[@jameswood8564]

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!

[@wyattoneable]

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.

[@DENicholsAutoBravado]

But darn, still no money shot. lol

[@myRatchets]

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.

[@myRatchets]

haha

[@youtubebitchcenter1463]

Damn KZbin be bringing in that cheddar 🧀 = 💵💵

[@bobdelabourer1307]

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 😂😂😂

[@Jay-xb6nc]

Your videos beat any money shot!

[@adamali4595]

Goodluck with your new workshop plus home bro......It seems this place was much better than earlier place....

[@fljagfan]

Excellent explanation. These were always very mysterious to me. Thanks for clearing it up!

[@myRatchets]

np, glad you liked it. cheers

[@davidostring803]

Thank you for explaining the vvt. I like the board holding the hood up & two less flies to breed. Keep up the good work.

[@messer7bc]

It's a comment to help this channel grow.

[@chrisrogers2230]

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.

[@myRatchets]

Glad you find them helpful, thanks for commenting.

[@abdalqadr1]

Smart man greetings for you from Iraq

[@richramcharan8080]

Very helpful. I was looking for someone to explain this. Thanks

[@chungaleta1234]

Best VVT explanation I've ever encountered on youtube. Thanks!

[@DENicholsAutoBravado]

Yeah, he did a better job of it, than I did.

[@myRatchets]

Glad you like the explanation, thanks for commenting.

[@iamthevanavator281]

As usual, excellent video. I always wondered about how variable valve timing worked.

[@myRatchets]

Glad you like the video, thanks for commenting.

[@Vladian100]

Thank you for the video! I think all educative videos should be like this!

[@kellyt5056]

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

[@marshallskater80]

Lol I love the little comedic parts of your videos. Keep it up!

[@dogburrito]

Great demonstration and explanation of VVT. What I'd like to know is what can be done to check the wellness of the VVT operation and to improve it. I run high mileage cars (around 300K) and have used premium synthetic oil (Amzoil) and treatments (auto RX) but a mechanic recently tried to sell me on replacement solenoids on my 03 FX35 (old enough that Infiniti/Nissan was of decent quality). He said they were clogged. I asked him what he'd do on his own car.. "blast them with brake clean". Can I pull the solenoids and examine for sludge - is that a decent indication? What engine treatments might be useful - Marvel Mystery Oil? Auto RX?

[@MowSow]

Fantastic video .. do you have a video that explains how a variable valve system can vary not only timing, but also duration and lift !?

[@CaptianKeyz]

What a fly episode. I like the way you explain things.

[@beetragg]

Enjoy your videos, and your humor!

[@robpond7385]

Your doing a great job explaining how it works ty

Man good job on explanation of that really hit home and I understand much more clearly now thank you

[@MathewTip]

Thanks for the videos you make, it’s so easy to understand

[@xamirozar]

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

[@ryanfelber]

This video was fantastic! Thanks for the great explanation

[@jkjwf]

Great video! Can you show a step by step video on how to remove and time a timing chain and phasers on 3.7 duratec v6

[@palomopalomo9755]

so thats how it works...!! you are the man .. you should start teaching.. great explanation...!!!!!

[@myRatchets]

Thanks, I can never be a teacher in real life. I rather talk to the camera instead of a class or something. Not a people person lol

[@Pfirtzer]

most techs I know are are very bad in socializing or having interaction with people. Nerds multiply in non-sexual way

[@stix562]

You already are a Teacher - the Video here proves it.. And yes nice job.. just pretend the people are cameras that talk LOL

Thanks man. Good job.

[@Peppermint1]

Also rev the engine above 4000 rpm at least once in a while if you are a very soft driver, this circulates the oil through the CVVT system

[@markvermeulen1372]

That statement has zero truth. Geez, buy a oil pressure gauge and learn something.
