Thanks you very informative and clear. I have been looking for something like this .I am in the process of replacing a head gasket on my 1995 Honda Civic ex it a D16D6 engine. I was trying to see how the v-tex lever was in position and the valve position upon top dead center on the number one cylinder.
Dude!! Very well made!! I wish you could go make mechanical training videos for the military and/or college.. Seriously, you have a gift for teaching with simplicity and demonstration my man.. I've always wondered how Vtec works..
This video has not been beaten even today imo. Most definitive video on vtec. A little question, as i understand, once opened, the vtec path pressurize and lubricate the whole intake rocker shaft assembly. The exhaust rocker shaft is lubricated through the small orifice in the middle of the head then through the camshaft cap. But how is the intake rocker shaft lubricated when the vtec path is closed?
Hi, thanks for the compliment, glad you found it helpful. something else that is interesting is there is a "oil dam" under the camshaft that traps oil in that area, so the bottom of the cam is always sitting in oil. very good for cold start as that oil will not drain. only the overflow will.
Hi BEZA! thanks for supporting! May 2021 bring the same to your channel! hope this rona and lockdowns can end so we can safely make more content this year!
@@RisingBoostYT Very much indeed! I have a D-Series in my own civic from 2001, and since I worked mostly on french and german makes, I greatly appriciate whatever info I can get on these engines. Mine is a D16W7 engine, and there is barely any info on those anywhere I tried to look for so far. In my understanding, the heads on the D16 series are cross compatible, so most I find are DOHC, while I have to stay on SOHCs. I'll have to rebuild that engine at some poibt in the near future, since that thing keeps hiding oil (no idea where it goes, it's dry underneath, no blueish smoke) I am sure it burns it tho, so your videos on this subject are an enourmous help. Thank you!
Hi Ramimax, the newer D17 / D16 motors with the coilpacks from factory, the heads are not compatible between the pre 2000 motors. Oil drains don't line up, so stick to the coil pack motors if you swop plan to swop heads. Hondas sometimes just use oil, if it runs good just run it, will probably still do 100k miles 😄
@@RisingBoostYT Now THIS was very helpful. It runs fine so far, however I will have to check the spark plugs, seems they did their run lately. In worst case, honda engines will run even without oil anyway haha. Autobahn seems to drink most of it up, so yeah... Your response made my day. ^^
Hi Chillenjack, for the 90s civics you will be looking at an EG or EK model. if you on a budget, try to get a D-series vtec model, if you want more power and turning potential you should look for a car with a B-Series engine. I currently have a D-series but it is just because they are way cheaper where I am from. to check if it has vtec, look for the vtec solenoid on the back of the cylinder head on the left side. also, Google the engine number on the front of the block, wiki will tell you exactly the specs of the engine. but know there is also economy versions of vtec that won't help with performance. so always google the engine number so you don't get a vtec-e motor.
@AngelNotLow they can move freely before the rocker assembly is bolted to the head. Once bolted down, the rocker arm sits between the valve and cam with the valve springs keeping the valves closed and rockers in place. The vtec arm are kept in place by the lost motion spings that sit above them.
Hi, sadly no. However, ivtec normally just means it is vtec and vtc combined, vtc is an adjustable cam gear controlled by the ecu and oil pressure. So the vtec system remain the same, some cars have vtec but it is an economy version of vtec that works slightly different. However the tech stay the same.
@@RisingBoostYT thank you for your response , i am about to changing the timing belt and clean the engine out of my honda and was just curious what i should look out for - hopefully i can get it running again (current status crank no start)
Thanks!

Thanks for the super, send me a DM on IG if you need more help
THIS is the definitive VTEC explanation; no one else has ever come close. 👌

Sorry you answered it around 8:07

This is amazing. A) thanks for the education. B) amazing construction and design, imagination. Neat stuff.
Hi Nic, Glad it was helpful! neat considering its tech from the early 90s
Been of for a few weeks so only got to check out all the videos to day love it keep it up dude
Hi Ullrich Thanks for the support!!
You make the assembly so understandable👌 seriously enjoying your content RB🤘. May 2021 bring your channel all the success.

Been looking for a 90’s Civic Hatchback. Just don’t know what model or engine type yet. Thank you for this

Brilliant!..thank you for the tutorial. Very enlightening.
Hi Casey, glad you found it helpful.
Thx mate this is the real guide
Thanks, glad it was helpful!
excelente video ilustrativo, justo desarme el solenoide para limpiarlo. es un video perfecto
Hi Jaun, Thank you. Glad it was helpful!!
very good video thank you !
Wow!! Thanks for the vid boost!! very informative vid so far about how vtec works! got sub bro!! Stay safe and God bless!
Hi, Thanks for the Sub! Same to you.
Very well explained.
Glad it was helpful!
Very informative ❤
Glad it was helpful
Very well explained 💯 I just subscribed. Can't wait to have time to look at your other videos. 👊 🤟
Hi CZ! thanks for the support!
Thanks very good video

Thanks for watching!
Quick question. I’m kind of stuck.
Do all arms move freely?
@AngelNotLow they can move freely before the rocker assembly is bolted to the head. Once bolted down, the rocker arm sits between the valve and cam with the valve springs keeping the valves closed and rockers in place. The vtec arm are kept in place by the lost motion spings that sit above them.
do you have one for the I-VTEC for honda ?
Hi, sadly no. However, ivtec normally just means it is vtec and vtc combined, vtc is an adjustable cam gear controlled by the ecu and oil pressure. So the vtec system remain the same, some cars have vtec but it is an economy version of vtec that works slightly different. However the tech stay the same.

Head d15b or d16a vtec
This head is from a D16Z6, code P08
Bellissimo video illustrativo, io ho raccordato lucidato il mio d series e un bellissimo b series guardate i miei video))
Hi Roberto, Had a look, very good work, getting a shine like that on the ports!
@@RisingBoostYT thanks very much))
