very true!! This pin engaging is what causes the famous "startup rattle" on newer variable valve timing (phasers) engines. If your engine's over 100kMi and lacks low rpm performance simply replace the PCV that is leaking unmetered air in the intake plenum
Normal Civics only have the economy variant of VTEC. It was designed to pick up your groceries a little more fast; now, if you have an RSX Type S, Civic Type R, and Integra GS-R they have the performance variant of VTEC which doubles the power output of the normal economy VTEC.
What a gift Hector has given us with this, and two other videos explaining in fantastic detail the inner workings of Vtec! I had the dreaded P2646 error on our 200K mile element, and followed his procedures through the vtec solenoid assy replacement, and cleaning of the separate screen and spool valve. Brought our Element back from the grave! No more fear about bringing the revs up past 3K. Not to mention the very succinct and detailed flow of the videos. Nicely done sir!
Thanks to a RUclips video from 1A Auto, I was able to do this job on both my Honda Element and my Honda Accord with the K24 engines. The job was easy. You can easily see why keeping the scheduled oil changes is critical to this system.
Speedkar is kind of like a professor of mechanics. How many ordinary mechanics understand what they're working on in this way, in terms of dynamic circuits? His knowlege of engines & transmissions is convincing. Also a great showman. A RUclips gem.
Don’t let this distract you from the fact that Hector is going to be running three Honda civics with spoon engines, and on top of that, he just went into Harry’s and bought three t66 turbos with nos, and a motec exhaust system.
My wife always asked me why you don’t use toothbrush anymore, now she knows 🤣🤣 By the way, you make the exceptional videos, we really enjoy and learn. Thanks for the exceptional job.
Always loved hondas, always known about VTEC engines, never knew a thing about it,just that they are quicker, You explained this so well, I appreciate this video! Thank you
I had an RSX type S, loved that vtec power band from 5-8k rpm. The 6speed shifter had the best short throws. Like a well oiled rifle bolt, smooth metallic feel.
Honda first used that engagement pin system on a domestic market motorcycle that had four valves per cylinder, but could selectively activate two of the four valves, or let them remain closed. Once it proved reliable, it evolved into VTEC, giving a phase change in timing, lift and duration instead of just valve area and swirl.
Found this channel a few weeks back. Man your explanation on cars is awesome. Coming from a young technician, you teach me a lot and I understand more and more everyday. So thank you very much.
You should be a professor of engines. You really know your stuff. Down to every bolt, valve, solenoid. It’s crazy. I love watching your videos and learning!! Thanks!!!!
Great video, speedkar99 At 10:31 and 10:45, you don't see any movement because the solenoid valve is pilot-operated. This means that it takes a bit of the fluid which it is controlling and channels it towards the clicking solenoid (the pilot), which then uses this fluid to activate/operate the plunger. So without oil, you will only hear clicks but see no plunger movement. In other words, the VTEC solenoid actually needs oil to first operate itself before it can operate the camshafts.
And that's why you shouldn't wait for your oil to get so very dirty before replacing it. Dirt can easily block the small channels in the solenoid valve and render it useless.
You are indeed a teacher ! I now know how to look out for most issues with my vtec AND to use my wife's toothbrush to help clean it !!! I currently use it on the dog's water bowl but this, THIS opened my mind to a hole new world!!!!
I’d rather have a belt that’s a wear item than a timing chain that’s much more difficult to replace when it goes bad at 200k. We lost a Honda to a failed timing chain.
I'll take a belt over a chain. Easier and cheaper to service if you plan to drive more than 200k. If you really want to argue about it, I perfer gear-driven cams. ;-)
Yeah. You and everyone else. That’s why Toyota and GM and lots of other manufacturers went to chains. However, it turns out that chains can stretch and jump a tooth from overheating if you are dealing with oil dilution and comsumption combined with excessive oil change intervals in modern direct injection engines. And since they aren’t a scheduled maintenance item-expected to last the life of the engine-they aren’t regularly checked nor are they easy to replace. If you’re lucky you’ll get a check engine light with a code for cam position. If not, the results are even more catastrophic than a timing belt failure because you’ll likely damage all of your pulleys and a metal rather than plastic timing cover sending all kinds of metal cornflakes to the oil pan. Gear driven is good.. but would be very complex for DOHC engines.. requiring worm or beveled gears combined with drive shafts (this was used on the RR Merlin for SOHC) rather than stacks of idler gears for each cylinder bank. The last automotive engines I know with gear driven cams are the Pontiac 2.5 Iron Duke and the Ford 300 inline six. Both straight engines with overhead valves that only needed two gears. A vee engine would need an idler because the camshaft needs to rotate the same way as the crankshaft for simplicity.
Just found your cannel and watched a few videos. Just what I need: Straight forward information, easy to understand for anyone interested in cars and engines. You just earned a new subsciber. Keep up the good work! Greetings from Germany
And a old sock :) lmao Really great channel! Using this to teach my son about timeless Honda classic! Thanks for the effort and wonderful quality videos. Keep it up plz!
Excellent video! Solenoid was likely working correctly just didn't have oil pressure to move the valve. It just acts as a pilot valve that ports a small amount of oil to actuate the valve.
I'd have shown it off with the OG b-series implementation, but this way easier to find, makes a better coffee table, and is clear and correct. Nice job.
Excellent explanation. Now I get it. I've got VTEC-E on my 98 Civic, and it does work in reverse of normal VTEC. Great 40MPG economy, and it's easily the slowest car on the road. (But I love it)
It is good that Honda routed the valve timing oil in the block. On my Camry V6, there is a tube outside of the engine that carries the valve timing oil. This created a problem (LSC-90K).
Another amazing video! Im so glad i found your channel, even tho i know how vtec works, ive never seen how its works inside an engine. Thank you! Keep up the great work🤘
1:25 I have a theory on why one bank is coated darker in oil than the other. The side that is darker is where the pcv valve is located (which would also mean that dark bank of the engine is bank #2). I think it’s darker due to the location of the pcv valve and it’s functioning causing a byproduct of its work by making the whole valvetrain darker on bank #2. This is my theory.
I thought it was due to VCM (Variable Cylinder Management) which shuts down 3/6 cylinders to enhance fuel economy. I know it caused quite a few issues for certain J series models.
My wife's 04 Civic has the mildest form of VTEC ever invented. AND it's an automatic. So there's that. Still, it's got a little (very little) zip to it. But I still appreciate that this engine still runs lock a Swiss watch and doesn't burn oil. We've put a new timing belt on it so I trust this car to go anywhere. Now if I could get up the ambition to do the headlight plastic restoration- those babies are HAZY
Great channel and content. Keep up the great work! The back side of the J-series engine is cleaner because of the VCM system (Variable Cylinder Management). There are different implementations, but it will shut down the rear bank of cylinders to reduce fuel consumption under ECO mode. The engine basically runs on the front three cylinders under light steady load. Later implementations could deactivate 3 or 4 cylinders. But you're seeing the result of higher average oil temps on the front half of the engine, hence the varnishing.
Thanks for sharing your knowledge, experience and expertise with us!Very happy you have such a supportive family even willing to lend you their very personal items to help in your career! Lol
That oil pressure has to be high, for vtech to work this efficiently!!! ...if it wasn’t I’d expect pin chipping rockers or vice verser ....well explained👍...
Great video. You did a great job explaining how the VTEC works. Thanks buddy. I was just wondering, can you tell why this engine failed in the first place? You made it sound like the engine was in pretty ok shape. Thanks.
All you're vids are top notch!! The knowledge and very well detail on how things work! Best on youtube hands down! Howeverrrr i was wondering if you can do diagnostic, and like symptoms/noise etc When they go bad etc (im trying to go for my cofq)
is there any side effects of lowering VTEC engagement? Mine is set at 4500 RPMs, I want to lower it to 3800-4000. Also, what is the highest RPM these engines can rev out to?
Perfect explanation. Answers my question that I had before comming into this video: does vtec need global synchronization and all the valves to switch at the same time. It clearly does not, as I suspected. Now I wonder what kind of external effects one would notice if for example half of all the valves would stay engaged in VTEC and half not. Are there any sensors for that so the engine would know that they stayed locked? Also, does anybody know why one half of the engine is more dirty ?
I believe that the one side of the engine is darker is because that side is tucked up next to the firewall and it gets hotter and cooks the oil just a bit more.
@@speedkar99 It's Portuguese. G-translated as: "If I disassemble an engine like this, I’ll never assemble it again, there are many parts. Congratulations on the work."
@@speedkar99 Awesome. I would like to ask some questions. 1. What is the cost of one of the tables? 2. How heavy would it be? Then I can go to the wife and see what she thinks!
Free Valve is the future! All these mechanical variable valve timing mechanisms are crazy complicated and rarely give that much of a variation, Free Valve allows for an infinite adjustability...
Great video! I'm looking at getting a 2.4 i-VTEC Accord Tourer. Unfortunately, given my driving in the 3,000-4,000 RPM range, I'll never use the i-VTEC. :(
these engines had a strong bottom end, but trash oil consumption out of the blue, one idle tues the engine will up and say "hey, I'm going to use 1L of oil for every 300km now, no matter how much you spend on getting me fixed"

This guy's tear down explanation of VTEC, hands down is friggin phenomenal. And the wife's toothbrush...😂 simply brilliant !! much thanks
Thanks for the appreciation
He is good there's no doubt about it.
The engineering that goes into that pin engaging and disengaging without any wear or damage, day after day, year after year, is just mind blowing.
Depends on how much you smash VTEC
@@speedkar99
😄
3 years driving an iVTEC engine yet to hit the pass 5500 rpm🤭
Metz Matu there’s also negative consequences of NOT ever using the performance capabilities of an engine
very true!!
This pin engaging is what causes the famous "startup rattle" on newer variable valve timing (phasers) engines.
If your engine's over 100kMi and lacks low rpm performance simply replace the PCV that is leaking unmetered air in the intake plenum
Isn't the 'startup rattling' during cold start is the lockup pin inside VVT Cam Phaser Sprocket Gear housing? (Not the sliding pin for high-speed cam)

Impressed by the quality of the construction. Only negative I see is a timing belt versus a timing chain.

@@ljpr360 Yup, definitely one/combination of them for having a darker valvetrain on one bank than the other.

At 10:40 that electric valve seems like opening a small high pressure oil line to push the (comparatively) bigger piston to activate the VTEC
