Unlocking VVT-i Intake cam gear on a 2006 Scion XD 1.8L

For Informational purposes only

[@rrsp253]

Thanks for showing that groove and the paint marks none of the other videos I saw showed that. Doing my Toyota Corolla 2009 intake cam for rattle noise.

[@cosmo7816]

Very nice video no one does the full procedure on KZbin yet that shows this cam indexing before installing the chain. I want to give you a hundred thumbs up but it would only let me do one

[@raulanaya6169]

Dude! you rock this is the easier way I have seen it done. I Just did my Rav4 2009 with your instructions. Thank so much for sharing this video your help is highly appreciated.

[@SuperDjnrg]

Raul Anaya No problem, just to give an update the scion runs great and the code never came back after this tutorial. Alls good in the world once again.

[@saefhindi6184]

Thank you for your valuable information. looks like Toyota updated the gear with new design looks a little different. i wish if i can send picture for it.

Question: when doing a timing and VVT actuator replacement, do I have to remove the camshaft from the vehicle? Or what if I unlock the new actuator and installed it to the camshaft already bolted to the engine?

[@romero10374]

I got the same cuestion

[@szymonvanderveen1295]

and how it went

[@lodhiautos9761]

Nice video. Its a great deal of learning. Thanks Gilbert.

[@SuperDjnrg]

Lodhi Autos no problem, anything to help.

[@lodhiautos9761]

Thank you for being so supportive. Regards.

[@tanako98]

you must unlock that VVTI cam. Check part numbers see which one you have!! I installed one and kept getting a P0012 code. I removed everything all over again. Unlocked that cam and installed and torqued it down. Then installed chain!! problem solved

[@danthaman2462]

im doing a timing chain install on a scion xd 1.8 2zr engine .. my question.... is the cam vvt in the locked position when u install the new chain to line up the timing marks

[@tabolubinda9024]

Why should you unlock the timing gear before you replace it? Do you have to lock it again after the timing chain is installed? Please explain.

[@javierquispe7131]

Thanks for the info. It is very helpful 😀

[@fireyourrocketts]

I tried to grasp info, in my case i have one that it had burnt oil on it, it was washed with a solvent solution and a hot bath at the machine shop but i still see burnt oil on some holes so i am thinking i will have to take it apart and clean it inside; this does not shows that but it shows some info i can use to put it back together i guess. Thanks for the video!

[@kesu90]

How did you end up remove the 5 point bolts to clean the gear>?

[@fireyourrocketts]

@@kesu90 Yes. The car was just put back on the road last 18, so far it is working, had some VVTi related code but I think it was due to oil not being at the required capacity; I put 3.9 quarters as required by manual but then drove 150 miles and seems there was some new oil consumption lowering oil level about half quarter, as soon as i filled it to point on the oil dip stick, cleared the code and it has not come back yet seems that was the issue; that sprocket I took it apart and expended like 4 or 5 hours cleaning and putting back together then in the camshaft making sure it would work. Mechanics recommend to just get a new one and install but I cleaned mine even assembled with one bolt from autozone as I damaged one bolt taking it apart, seems to be working fine but still not enough miles in the engine since back together to tell for sure.

[@kesu90]

@@fireyourrocketts I just ordered CTA Tools 9880 5 point 10mm socket to remove the 4x 5point bolts. Wish me luck! I am actually rebuilding the entire engine because of oil burning issue.

[@fireyourrocketts]

@@kesu90 I did mine for exact same reason, there are some struggles to he had, between that, time and many times some tools needed it took me 3 years and 4 months to complete mine since started, I did more tan engine, also AC whole, did replace radiator, did the evaporator on center console, all clutch system, gas pump, then both axles, shocks/struts and now finishing with all 4 brakes; adding a radio with backup camera and after all have to replace windshield that broke due to a flying rock on the day car was back on road

What could be the problem if you fix it locked

Can pliz do the video of it while assembling en desembleling

[@johnbaptist7476]

Hello Brother Q ? why should i take the cam out ?please🙏👌🙌 Please see if I am right thanks for your response . First i install the gear assembly while it is unlock , then torque to 47 lb , then lock it then install the chain . Am I right brother 🙌🙏

[@aldocano6458]

Thanks for the video is so helpful...

[@MiguelPerez-fj6ls]

I'm more confused now cause you didn't actually do it

[@eliezermerced4199]

Greetings, those motors if the chain is mounted badly they bend the valves?

[@KennyKashauti-jg2ik]

So what happens if you fix it locked is an problem

[@AnythingEverythingGh]

Good question

[@ebuzek3648]

So what is the purpose of unlocking and locking it back?

[@SuperDjnrg]

What to allow the oil to enter the VVT gear

[@ebuzek3648]

@@SuperDjnrg won't the oil pressure do that? I'm replacing mine on my 05 Corolla

[@SuperDjnrg]

@@ebuzek3648 there has to be oil in it to do it thats why you open it i got the derections from all data when i was working over at Volkswagen dealership.

[@Mojo-cg3xo]

good question. I didn’t do the unlocking and then locking procedure. I just pulled the intake camshaft with a gear attached to it from the junk yard and installed it on my Corolla. Sure enough I got the check engine light on with a P0017 code. I’m going to follow the unlock/lock procedure in this video to see if it fixes the check engine light. Funny thing is my car is running ok but I can tell it’s not working as efficiently as it should be.

[@danthaman2462]

my scion book says both cam gears need to be locked ex & intake before u install new timing chain .. im new to 1.8 with vvt cam gears any info u can share will be helpful im not changing vvt gears will they already be locked ? do they unlock when u take the chain off ?

[@SuperDjnrg]

Dan Thaman the only advice I have is to make sure you change the oil pump when you're doing this particular service. And clean screen underneath 1st cam journal.

[@SuperDjnrg]

Dan Thaman and also I believe they remain locked once the engine stops running they operate off of oil pressure low low oil pressure will keep the cam gear lock higher oil pressure will unlock it.

[@sushantchari4604]

If I direct remove vvt-i without locking and only camshaft is replace than vvt-i can use again

[@thorstenpannwitz2345]

I still don´t understamd the procdure, what makes the difference to tighening in unlock then locked position. Why does this make a mechanical difference? After all you turn locked an built in. So why?

[@SuperDjnrg]

It's in the tech manual to perform this procedure. You would have to ask Toyota.

[@teeman1494]

If you do not unlock before you torque the sprocket, you risk ruining the vvt lock pin inside the sprocket because all the torquing force is exerted on the lock pin since it holds the sprocket gear and its inner vane together while in the locked position. You can look up a teardown video of a vvt sprocket gear to better understand this.

[@thorstenpannwitz2345]

@@teeman1494 If so then the vvt-i shouldn´t be working direct after installing. Moreover i thing they simply constructed it poor because the hole(bore of the pin is washing out and not round after some working hours. But they don´t want to tell the customer.

[@strikermaximus365]

If i put an impact wrench on it and took it off will that fuck it up.

[@disarmyou84]

Bro! Literally the same thing happened to me. I bought a 2009 Toyota Camry with a blown head gasket to fix and sell. I ended up getting a whole other refurbished head from the machine shop that came with the cams and gears already. I put it all together and just like you said it runs fine and has full power but that damn p0012 code keeps coming back. I’m sure the machine shop didn’t do the unlock and lock procedure when installing the vvt gear. I thought maybe I messed up the timing but the car ran fine. I even replaced the oil control valve thinking that that would fix the check engine light. Now thanks to you I know the procedure to install the vvt gear and will do that so I can finally be done with the car!!! So just to be clear I have to unlock it, torque it, then lock it. Right? And I can do all of that with the vvt attached to the cam shaft just with that bolt hand tight. Am I right???

[@SuperDjnrg]

Yes, you are correct. Don't forget to clean or replace vvt filter. It's under the first cam journal where you see a nipple in the middle of the journal.

[@disarmyou84]

Gilbert Galvan thanks a lot bro I really appreciate it.

[@disarmyou84]

Hey one last question. After I torque it, I have to use the compressed air to lock it and turn it again?

[@SuperDjnrg]

No after you unlock it torque it and then manually turn it by hand to lock it again. Then put the timing chain and time it. Then you shoud be good.

[@disarmyou84]

Gilbert Galvan thank you my good man

[@johnbaptist7476]

Hello friend , sorry but I am so confused . So i buy it new from dealer , do i have to adjust it ?

[@SuperDjnrg]

I would double check it, never trust anyone's work but yours.

hello how are you I have a toyota corolla s 1.8 2009 ase Engine noise when I turn it on Cold in the morning per second and ask me if you can help me what can it be to regulate it

[@mvnga3362]

cam phasers all toyta and lexus

[@m7cruz]

What happen if you don't unlock and u install it but the cam gear got bad? yea you say code is going to come on but you have to but another cam gear

[@SuperDjnrg]

When it unlocked it set up so oil enters the vvt gear. If its locked oil cant get in and it will rattle when you start it continuously.

[@m7cruz]

@@SuperDjnrg thank you so much I haven unlock my is a new one couse OEM one was making a lot of noise so I replaced it with after market one I don't know is a good choice but OEM is pricey I need to remove it back and unlock it and put them back right?

[@danthaman2462]

im not getin any cam codes but my timing chain was makin a lot noise till the oil got up there ... where did u get ur vvt gear .. should I change the vvt gear while im in there ?

[@SuperDjnrg]

Dan Thaman yes do so i got mine from dealer it was way to much i dont remember how much.and do both and your oil pump and chain kit and all timing guides.

[@davidthecardcollector]

Dan Thaman. I have a camry and I was getting a knocking noise. I replace this vvt gear and it still made the noise. Turned out to be the vvt screen clogged which was behind the Power steering pump.

[@SuperDjnrg]

Dan Thaman yes change both gears, also check the vvt filter under the first cam journal if you look at the journal from the top you will see a nipple in the middle its derectly under it also dont forget to make sure the orings between the first journal and the valve cover are new. If not it will loose oil pressure at the vvt solenoids.

[@WillCarrot]

@@davidthecardcollector was it just on start up for a few seconds?

[@davidthecardcollector]

@@WillCarrot It was a knock at idle, sounded like it was coming from front of engine. You can get a similar knocking sound from the bottom of the engine only on startup which turned out to be balance shaft bearings. Once they get enough wear on them the knock will be all the time.

[@danthaman2462]

ok.. I plan to change chain guides .. chain and tensenor and vvt gears etc parts geek has the best prices.. While I got it torn down I want to change as much as I can...

[@SuperDjnrg]

Dan Thaman make sure you change the oil pump, i didnt the first time and ended up tearing it down a second time. The oil pump is actually the timing cover order it as a set because the timing cover is worn also not just the pump.

[@danthaman2462]

ok

[@Outrunninaround.]

Should come in the box unlocked

[@danthaman2462]

good info dude

[@danthaman2462]

when u did ur install did u take the timing cover off ?

[@SuperDjnrg]

Dan Thaman yes its not that hard i think i have a video on it. I will get back to you in a bit.

[@danthaman2462]

Do both the ex & intake need to be locked vvt to install timing chain ?

[@SuperDjnrg]

Dan Thaman no only the ones I have on the video the other one is different doesn't need to be unlocked

[@SuperDjnrg]

Dan Thaman the reason I had to do this because I kept getting that stupid p0012 code and it would not go away no matter what I did until I tore it back down and unlock the timing gear and then locked it after I had it on the cam code never came back since

[@danthaman2462]

ok if u have a video on it that would be great.. only place a see the vvt cam gear is rockauto and partsgeek.com... im thinking maybe sense im going to tear it down I should replace vvt gear and maybe lifters ? thanks for any info you have on it

[@SuperDjnrg]

Dan Thaman I'm trying to send it to you but it won't unless you subscribe to my channel

[@DragonSailor-Hooah]

DOES IT HAVE TO BE INSTALLED UNLOCKED?

[@DevJB]

The point of installing it while unlocked is for when you torque it down it doesn't ruin the lock pin. After the vvt phaser bolt is torqued, then you hand turn this phaser clockwise to relock it. There is a hex feature on the camshaft that you should also hold with a wrench to stop movement of torque on the camshaft when you torque this phaser bolt. On Alloytec and Ecotec engines I don't perform this, on Toyota I do because most of these (especially on 1.8L) have a faulty intake phaser "numerous revisions" to begin with and will need the updated vvt phaser, retimed, and new tensioner. They are sensitive and expensive.
