@@speedkar99 yes. Sir. U r the best.I really like to watch your video so much and also I am watching the other video from u.This is a good chanal to me. Thank you again.
Your teaching fast and engaging and touching every detail. There is a huge difference between this video and that of others who thought the same topic.That multimeter idea is very scientific.
the amount of info in this video....... is priceless, i have to say, this is such a comprehensive coverage of the subject...... maybe some people wont get it all on the first shot, but as you go on, i can see them rewatching it and getting it. great vid man!
+Yathu prem yes Very different, the cam shafts actually have different cam lobes on them and it changes profile. See Engineering Explained's video on VTEC vs VVT
You explained this so well! Thank you so much, I understand the function of the VVT and the auxiliary components a lot better now. I wish you could branch out into tattoo machines too, because the way you explain things is awesome and thorough.
Very elegant and precise presentation! A closed loop system with the cam position sensor as feedback mechanism to computer for vvt oil pressure control.
100% UNDERSTOOD . . . NO AMBIGUITY. YOUR ABILITY TO EXPLAIN CONCEPTS IN ENGINE DESIGN AND WORKING PRINCIPLES IS ADMIRABLE. . . IN SHORT, I THINK THIS CHANNEL IS A TREASURE.
Props Speedkar99. You make easy to understand, easy to watch videos. Respect ! 1. Your toothbrush... Can I borrow it ? ;-) 2. Your gloves grew fingertips! Woah !
I just need to add one thing that's incorrect...Great video btw. At 6:13 in regards to the oil pressure, the oil control valve inside the oil pump is what regulates the oil pressure, at the bottom of that oil pump is housed a plunger and a spring, where that bolt is. that spring relieve itself at a specified pressure, that basically keeps the pressure in check for the entire engine
Man.... This guy really knows how to make informative Videos. I'm hooked to this channel. Keep it up.. !!! Ohh.. And the toothbrush as a pointer is really Original, lol
And use a high quality oil and filter. Fram Ultra filters and Pennzoil Ultra for me. $25 for five quart jug on Walmart's website and filters on eBay that come to about $5 each. Change your oil every 5-7K miles and you're good to go!
Good advice, I would also recommend checking your oil between changes. Late model engines especially the 4 cylinder GM's consume a ridiculous amount of oil (1qt/3000 miles) at that rate if you push oil changes farther out you can easily be 2 or more qts low. See cars at our shop every day running like crap with no oil on the stick.
Thank You! Came from Vanos BMW to V-tech Honda K24. Failed to set timing on K. Couldnt get idea how that Intake sproket works. Gonna give it another shot. Every time intake cam goes off alignment.
BEAUTIFUL!! I just sent this to someone to emphasize the importance of oil changes. besides wearing out the internals and bearings and cam journals, you'll also kill the valve timing mechanisms. those small holes will clog.
Just a point of clarification: advancing a camshaft increases low-end power, retarding a camshaft increases top-end power. As little as 4 degrees can make a big difference in the effective rpm range.
One again Speedkar99 you nailed it. Learned something new again. Was waiting for your brothers’s underwear to make an appearance! Thanks for another great one
Thanks for making this I have a 2.4l Toyota AZ motor so I wanted to know how it worked. I get the concept just not the execution. Thats crazy they use a solenoid to used a oil filled "clutch" to adjust the timing to multiple positions.
great explanation, i think my old rotax engine in my ski-doo snowmobile had a variant of that theory and i know it worked quite well greatly increasing power especially low end torque , thanks
Thank-you so much for this video my cars bogging out uphill and under load and throwing p0016 p0017 codes the timing chain is correct so will take apart my vvt gears thanks for this info :)
+Jithin P V ah i see, I aim at those who have a little bit of automotive knowledge, if you want some background, take a look at my how an engine works video.
I’m guessing that cylinder head is to a Toyota 2AZFE 4 cylinder motor, and it was pulled because the engine had developed a blown head gasket condition, due to the constant expansion and contraction of the cylinder head, causing the head bolts to pull the soft aluminum threads on the block. I had that motor on a Toyota Camry, and I needed to buy a Time-Sert threaded bushing kit to fix the block. This thing was expensive, as well as the whole repair. Expect to spend at least 2 Gs for this repair.
Please note - BOTH the pump and the valve develop the oil pressure. (You are right in that only the pump provides the oil flow.) This is a common discussion item on a lot of threads. Pressure is developed when the entire vessel that the oil is in provides pressure on all sides of the oil sample. All sides. That means in this case, you have oil pump, oil valve, oil galleys, everything oil.

I don't know what's more genius... the design of variable valve timing or your videos explaining how It works !
+Tripp M I'm the genius here.
@@speedkar99 yes. Sir. U r the best.I really like to watch your video so much and also I am watching the other video from u.This is a good chanal to me. Thank you again.
Well said
You ran out of your brother's underwear?
Agreed! This video is the perfect explanation as to how the system works.
Hands down one of the best "How it works" videos I've seen.
One of the best videos I've seen. 100% clear and thorough information. This guy speaks like a true Genius! Great job!
Thanks for the feedback
Brilliant explanation of all aspects, especially the feedback loop via the camshaft position sensor. Like your enthusiasm too!
Best explanation on this topic on the internet. Couldn't ask for more.
Thanks for the feedback!
Great video, have been struggling to understand how the oil flowed to the gear but you've explained it perfectly. Cheers!
Thank you
Perfect explanation of the VVT. Seems like every car after 09 has a Variable timing system.. Thank you!!!!
Yep, it's the way of the future
Best explanation I've seen so far thanks for posting. Can't emphasize enough the need for oil changes and monitoring your oil level.
Agreed
This is the best explanation I have ever come across for variable valve timing.
Awesome
Your teaching fast and engaging and touching every detail.
There is a huge difference between this video and that of others who thought the same topic.That multimeter idea is very scientific.
+Anaele Raphael I'm glad you like my teaching style, che k out my other videos for more.
Shows how much effort you put in making these videos such a great way of explaining things ..wow ..nice work man..
Thanks, I appreciate your kindness, yes there is alot of research and effort that goes into making quality content
More than 4 years have passed... Very well explained, so clear. Thank you very much!
You have demystified the vvt technology. Thank you very much.
Nigeria.
+Anaele Raphael your welcome. It's pretty simple
the amount of info in this video....... is priceless, i have to say, this is such a comprehensive coverage of the subject...... maybe some people wont get it all on the first shot, but as you go on, i can see them rewatching it and getting it. great vid man!
That was well explained you're the first person to explain it with so much clarity
Thanks,
Clear and to the point is my objective
This is the best and most in-depth vedio I've ever seen on how variable timing works. I love your vedios, keep up the great work!
Thank you
You are a great teacher. This video is awesome, like virtual textbook being taught in a Classroom. Well worth it and I will watch this many times.
Thanks
Waited so long for this. Nice video. New toothbrush??
+Yathu prem thanks, I knew you were waiting :)
Yes fresh toothbrush from my brother
speedkar99 VTEC is a lot different??
+Yathu prem yes
Very different, the cam shafts actually have different cam lobes on them and it changes profile.
See Engineering Explained's video on VTEC vs VVT
you have a very generous brother... haven't you? :P
mid-video, like a wardrobe change
You explained this so well! Thank you so much, I understand the function of the VVT and the auxiliary components a lot better now. I wish you could branch out into tattoo machines too, because the way you explain things is awesome and thorough.
I love how u dnt waste time.. U get straight to the point and cover everything
Outstanding sir!! Talk about bang for your buck!! That was likely in the top 10 of the best 8 1/2 min I've spent in my life!! Thank you
I agree with those who say this is a great video. Well articulated. Also he talks fast ..but not too fast. I learned. Thank you
You are welcome
amazing explanation! i read and read about vvti and it was only this video that made it clear for me! thank you!
VERY VERY detailed and easy to understand explanation. im NOT an Engineer nor a Mechanic but im beginning to understand how it works.

I'm guessing toyota, 1.8
Very well explained even the newbies understand clearily!
Dude every time I'm clicking through videos on YT, seeing that toothbrush just kills me XD. You got me. Subbed.
Great! Concise explanation. No jungle beat music. Thanks.
Thanks, I try to keep things short and to the point
you have a really good vocabulary
Hmm no one has told me that before. Thanks
I mean, he did say nitrous oxide when he meant carbon monoxide. But he is way better than Biden hahahaha
...and that was a couple of gran worth online course compressed into an 8 minutes free video.... brilliant
I'm glad you appreciate my work
Boy how did you learn all this stuff? You are incredible!
I research it online then titivate with the engine to make sense of it all
Good one. Simple to understand. Perfectly explained. Thanks a lot.

It's 2022, but you just gained a new subscriber.
Great videos 👍
Thanks for subscribing
Great explanation of the variable valve timing!
Glad it was helpful!
thanks a bunch, valve timing has been kicking my ass in school
This was 6 years ago..How did i miss these videos?? Shit man...
I got lots of videos like this, check them out!
Wow! Wish I could be that great in explaining.....anything. Great job!
Awesome video by the way. Hadn't seen anyone explain how the phaser relates to the VVT and overall engine timing mechanism.
AAA+++!!! I have seen a few of these, and could no get my head around it, (pardon the expression) and now I understand it perfectly!
Best explanation I've seen. Great job!

Thanks! I'm glad you love my videos, please share and make suggestions for new ones.
Your videos are addictive!!! Can’t thank You enough ❤️
literally first video on this that made sense ty.
This whole system is dependent on oil flowing though these small passages. Change your oil regularly.
And use a high quality oil and filter. Fram Ultra filters and Pennzoil Ultra for me. $25 for five quart jug on Walmart's website and filters on eBay that come to about $5 each. Change your oil every 5-7K miles and you're good to go!
Agreed, oil is very important even more so for newer engines with tighter tolerances and thinner oils
Good advice, I would also recommend checking your oil between changes. Late model engines especially the 4 cylinder GM's consume a ridiculous amount of oil (1qt/3000 miles) at that rate if you push oil changes farther out you can easily be 2 or more qts low. See cars at our shop every day running like crap with no oil on the stick.
Excellent video! I Understand everything you described!
mike jones Very much agree. Having that issue now with my 2013 Highlander.
Thank you for brushing that subject.
"brushing" 😏
Thank You! Came from Vanos BMW to V-tech Honda K24. Failed to set timing on K. Couldnt get idea how that Intake sproket works. Gonna give it another shot.
Every time intake cam goes off alignment.
Does the VTC pin lock when you rotate the engine?
Excellent video. Just the info I was looking for to start in on a timing issue.
Wow wonderful explanation! I'm going to subscribe even tho this is the only video of yours I've seen. Great job!
awesome video!! this guy should be a car engine designer or something like that !!!
