A step by step how-to guide on replacing a worn VVT intake pulley on your 4AGE 20 valve silvertop engine.
The process is the same for the 4AGE blacktop, just the part number for the pulley is different.

Hey Terra, good job on the video. Only thing I wanted to add is that when ignored the VVT pulleys can stop working completely and go silent again. The best way to test this is simply a test drive with and without the VVT solenoid plugged in. Anyway funny story for you- me and a guy I know where looking at my friends 20V engine because it was ticking loudly. He noticed one bucket has a good 0.5mm gap from the cam and when taken apart we found that the shim was sitting on top of the retainer instead of on the valve! one of the collets had a few dents but was still useable.
I'm glad I found this video. My car has a similar issue and I'm trying to diagnose it. Hope you still post on OCAU sometime.
Sorry for the stupid question or some reason I read it as ae111 which has the blacktop. I recently converted my redtop to a silvertop and this video I really helpful. Keep the videos coming!
Thanks a lot for the vid bro. I just did a Silvertop swap in my rolla. And the engine was doing the diesel sound,was gonna go lash out at the trader and return the engine until I saw your vid. ^^ Happy its nothing major.
The "thing" that get worn on the pulley is the "bushing". The rubber that is physically connected to the camshaft itself...
You will have to completely open up the whole VVT-pulley in order to fix this (pain to do properly since it utilizes springs in order to "not pull over") by adjusting the bushing 180 degrees(flipping it to the other side). I have done this procedure several times, mainly on newer VVT-i's. But also on my BT 20V as well.
Nothing i'd recommend to the average "garage-Joe" but in comparison to what these baby's cost it could be worth a try.
Dude thats an awesome vid!
You've basically just shown me how to change my timing belt. fantastic.
I have a an ae111 bzg, its a nice car, nice engine.
Thanks dude , yes i contacted Manon Racing and they have given me a fair quote about $107AUD for Waterpump includ shipping .
Also i love your 101 man , its super clean and well maintained , Kudos for the information .
Hello,
Great Video! But can you tell how you unbolted the VVT pulley bolt? Normally it's pretty difficult to remove and i think normally one should remove the cam cover, use a wrench to hold the cam and then unbolt it.
I more like it doing your way but i'm not sure if it's save to just unbolt it without removing the cam cover.
Thanks!
Lovely message ❤
"calibrated forearms" hahahaha nice one :)
I always try and push a little bit more tension on the tensioner pulley myself when in this situation, the belts really love to flap around at high RPM and it prevents the belt kicking itself off a pulley.
Nice video mate.
Top video man. You have confidence in your abilities.
beautiful engine man. iv got a carby 4-AF in a corolla.
Great videos man un paralleled attention to detail
Thanks for this video i will never take my car to a mechanic il just change the VVT my self
Nice n informative video.. 1 question.. The solenoid u directly connect to battery.. Which is positive n which is negative?
Excellent man thank you I will try this myself and replace cam belt
Great video, what is the fix since the VVT gear is no longer available?
The man, thanks for this tutorial!
great stuff! just one bit of added info, it is possible to fit a blacktop gear onto a silvertop, been done here in S.A. would be interesting to see whats exactly inside these pulleys that get worn.
Very detail explanation. Good work.
this video really helped with my ae101
beautiful lavin you got ... never seen such a clean one ... good work ..
Hi terra I apologize for the inconvenience but I have a problem in my ae86 I made the change of engine and I have a 4age black top and loses power aparatir of the 1900 rpm. already check the combutible pressure and this ok could be the vvt pulley
could you tell me guys which part fit on the 4AGE silvertop... could you tell me the right part for the silvertop, I know for the blacktop its a 13050‑16020 and for the silvertop.... its the same... thanks everyone...
The one I use in the video is the silvertop part number.
The blacktop has a different part number.
will it give an engine check light when the engine is at high rev
Good video, you didn't lock the cams, how didn't they spring back or forward?
My BT 20v does the same. Id love to fix it but I can't justify spending that much on a pully to fix the diesel sound. Would having a warn pully over time damage the engine?
BloodSeekar well in theory yes it damages the top end and worsens economy and power
My lexus is300 2jzge vvti makes the same noise should I do the same thing
Hello. Anybody can confirm if VVT pulley + intake cams of blacktop can be swapped on a silvertop head? VVT pulley is dead. Product is discontinued. Was thinking maybe swap blacktop intakes + blacktop vvt pulley.
Or leave it ticking as it is altogether.
Any help greatly appreciated.
***** hey, if the VVT solenoid is unplugged, will you be able to start the engine? Just checkin 'cause mine doesn't start if it's unplugged.
Do these start out as a rattle when you start the car and eventually get worse over time as they wear out?
Great video. Thanks.
hi, i got a 1993 toyota levin gt apex 20v 4age, car idles rough , sometimes high, my main problem is the check engine light comes on randomly and car stalls, i recently put new oil, new oil filter , new fuel filter , new spark plugs , still got the problem , as soon as the check engine light blinks ,the car stalls but dont shut off
I used to have a Toyota years ago and it would do that.. Check your distributor cap and rotor. Every so many months I had to change mine because some of the points would get worn down
What oil weight would you recommend with the 20v motor? From what I've read, the vvt cam gear can get picky with such. Thanks in advance.
Awesome awesome video. Thank you
great video u real go into detail , Do u know the part number for the black top vvt pulley
nice video but you should of changed the o rings
If you keep using your car with a bad vvt pulley can it do damage and does it lose power
You might loose a little power if it doesn't change the cam timing properly.
I don't thing it will do much damage, beyond being noisy and possibly leaking oil eventually.
Hello friend, I congratulate you on your video, a question, how many degrees did you put on the adjustable exhaust pulley and what direction did you notice?
I advanced the exhaust pulley by just a few degrees, any more and it reduced midrange power.
@@TERRAOperativeOriginal Hi brother. May I know where you set the ignition timing upon advancing the exhaust cam gear? Any acceptable range you could advice? Thanks brother!
I set it to about 12 degrees or so and ran high octane fuel.
@@TERRAOperativeOriginal nice. I set mine at 12, too! Thanks, mate!
Thank you Matthew .
How can remove the Vvti sensor
Good Video, and really nice Ae101
Super video, love the carbon spark plug cover, do you have a link to where you got that?
Would it be worth it on a engine thats done 2900000 its daily so dont get trashed too much.
Ive had people tell me that the sound is just wear but doesnt actually effect anything? Why is the sound bad, i have my vvt hooked to a switch, i can force it off, on, or leave auto, how much of a difference should there be with the vvt actuating by itself?
Not considering the power and efficiency loss caused by the worn pulley you get an erratic working on the cam-to-tappets (or whatever your particular cam lobes push on to operate the valves). Basically accelerated wear can happen which is never good. And if you don't get tired of that noise well then its all cool.
So you are saying there is an effect on performance? It wont engage as quickly or on time? Is there damage being done to other things?
Well a lot of it really depends on your driving style.
VVT's were introduced to combat stringent emission regulation when consumers craved for more power and better gas mileage. In essence you get a well tuned low RPM torque without losing in hight RPM just by adjusting timing (VVT). If you operate the engine at low RPM and never get to a point where VVT kicks in, you can happily live without it.
Other thing that can happen is oil leak. Due to construction of VVT pulleys there is a viton oil seal between two plates that slide relater to each other to achieve difference in timing angle. At certain point this seal will crack and start to leak oil. You will probably have 100k+ miles clock and start replacing cam seals which won't really help.
What radiator do you use?
Sorry to be off topic, but where did you get that carbon cover for your engine?
i have a AE111 Levin ( Blacktop 20V) and i just done the major service and had trouble finding parts in Sydney , would you know where i could get the Water Pump and Timing Belt Tensioner ?
1 question if i keep my st like that and still welding the pedal on the metal what can happen
Also,would you mind telling me if your check engine light switch on after 4000rpm? Cause mine is switching on after 4000rpm,when I lift off the accelerator. Thanks.
Make sure the speed sensor wire is connected to the ECU if it's an engine swap, you want to connect it to the purple wire with white trace.
Can you pull the code and let me know what it is?
***** It is a swap,but am not a mechanic, and I don't quite understand the wires...How do I make the check light flash to pull the codes? Is there any site you can advise me to get the pulley? Toyota Mu is asking 1000AUD for it. Too expensive.
Can you still run this motor with an automatic?

Hi brother. What is your exhaust cam setting right now? Any advise on a good cam setting on a relatively stock engine? I want to get some more kick at low to mid rpm for city driving. Thank you!
I retarded the exhaust cam just a couple of degrees to broaden the torque curve (at the expense of lowering peak torque a bit)
You can freely play with adjusting it a few degrees in either direction to experiment and the ECU won't freak out.
@@TERRAOperativeOriginal when you delayed the ex cam, where did youset the ignition timing? Thanks, mate!
could you please tell me how and where to get that cam cover and spark plug cover from? i NEED one and cant find anywhere. atleast ones with the twincam engraved in em
Hi buddy. Could i have some help please. What engine oil do you use in this engine?
Just wondering why a blacktop is replaced by a silvertop
Very useful- many thanks :)
thanks man you solved my problem😁
can you say what cause the engine to rattle
thanks for that vid. good job man.
Nice vid lad.
is it safe to add 12v to the solenoid?
hi my name is ryan i have a toyota carina gt japanees model and i want modify my engin how can i do in a simple way
It helps me alot :) thanks TERRAOperative! More HP!
Your 4age is mint
How did you get the crank case cover carbon? it cant be vinyl or it would melt, so was it custom made?
Sweet Rand Yeah. it was a custom full real carbon fiber part made in a small run by 'Manon Racing Products' in New Zealand.
awesome, looking at the site now. I live in NZ so thats handy. I own a 97 trueno BZR and wanted to add some mods. Your car is so clean and tidy especially for its age (assuming its a 92/93?), its impressive.
nice vedio are you seeling your car?
Please give me link for the order pully cam
The one in the video was purchased from Manon Racing Products in New Zealand, if they can't supply one, you might have to get one directly from Toyota if they are still available.
Very good video ! !
hi, what exhaust header are you using?
Rashedul Hasan It's a HKS 4-1 racing header that I got ceramic coated.
Hey man any advise in where to find a silver top vvt gear? really struggling found one for like 700 dollars that's mad! any ideas bud?
Mrp, smr2u.com, battlegarage, sqengineering.....
I got mine from MRP (Manon Racing Products) in New Zealand.
I think Toyota miiigghhttt still make them, but they will be a bit pricey without a trade account.
That drill does not work the same as a impact gun, if you use a torque bar with it it won't be torqued to spec. and you may break the stud or bolt. i have heard of people destroying blocks because they tried to torque the head down like that. Dont be fooled by the mechanics that use them with a torque bar.
The 'drill' I use on the wheel studs is a true electric impact wrench. I know, it's mine and I bought it. I also have the DeWalt battery drill so I know the difference....
Using an impact wrench on a cylinder head is never advised and is a silly idea, that's what torque wrenches are for.
I never said to use the impact wrench for the head bolts but when used with a torque bar on wheel studs, it's perfectly acceptable practice.
Oh ok sweet, i could see it being handy, having a air hose gets in the way.
thanks
Pick up cam vvt
What is different vvt blacktop and vvt silver top??
Blacktop has more aggressive cams, and the VVT operates under slightly different conditions, also blacktop has slightly higher compression IIRC.

thanks mate!
what disc rotors are you using in front?
I can't actually remember... They are slotted ones from ebay.. :D
Not a cheap brand though, but I did get them skimmed on the disk brake lathe to get them spot on and perfectly square.
Граматно расказал))) спасибо !!!
Hola alguien q me traduzca por favor, porq hace ese sonido como diésel y luego no?
Q pasa
La polea de admisión variable estaba desgastada y fue reemplazada por una nueva polea.
(Perdón por usar el traductor de Google)
and where can i get one from
The one in the video was purchased from Manon Racing Products in New Zealand, if they can't supply one, you might have to get one directly from Toyota if they are still available.

My 4age blacktop had a stuffed vvt it ran like absolute crap no power whatsoever only at high rpm it would pull. After I replaced the vvt pulley with a second hand one I have the power back but I still have a rattling sound at idle and a bit of a rattle at about 4,500 revs.
Nice n informative video.. 1 question.. The solenoid u directly connect to battery.. Which is positive n which is negative?
It doesn't matter, you can connect it either way around as long as you disconnect the plug fully.
Great video, thanks
