Toyota VVT-i Engine Timing Chain is BAD? How to Inspect 

The engine has markings that tell you how to align everything very easily... Toyotas are excellent cars to service...

At 10:05 into the video, Peter shakes the chain and the left yellow link jumps into the correct position. You may be wondering, "Is it fixed now?" No, because now there will be excess slack on the left side that does not have a tensioner. If you think, "I'll take out that slack by moving the chain another tooth on the bottom sprocket," then you will move the third yellow link down there out of its correct place. Another important factor that Peter covers in another video, but not this one, is that the two camshaft sprockets need to be aligned with one another, using the small indentations. The two opposing indentations need to be in line with each other, parallel with the valve cover. If you rotate the camshaft sprockets away from one another in an attempt to remove slack in the top part of the chain, the two indentations will no longer be lined up, meaning the camshafts will be in the wrong orientation. The bulky camshaft sprocket (the VVT gear) has just one tiny indentation. The other sprocket has three indentations. (On a 1zz-fe), it's the indentation by the EX that needs to be lined up right next to the indentation on the VVT gear sprocket. When done correctly, the two cams over cylinder 1 will be pointing slightly upwards, and towards each other, at a 30 degree angle.

Peter Got a 93 corolla with 1.8 what fitting you recommend to check fuel pressure. Got a gage and different adapters but this engine don have. Room to put the fitings

Very well video Peter I am currently struggling to recover the tensioner it is very stuck very tight for time, how can I remove it?

Hi Peter! What is a right tensioned, timming chain looks like? In my vehicle, a Toyota is tiny bit loose on top between the top sprokes but I listen it rattle a bit in low gear when going up the hill. My Toyota has 245,000 km Thank you

The great thing about timing chains themselves is that they last ages and give you warning when they're worn out. You can barely hear it in a VVT-i engine.

I have a 1nzfe fielder engine, when I accelerate a lot it makes a noise like "vummm thererererere, vummmm therererereee" seems to be spinning and rossing in one place and with that insistence of accelerations it ends up loosening the pulley and the belt falls. Would you like to know what happens to this engine? I ask for help Mr. Peter

شكرا جزيلا لك على الشرح المستفيض في حل المشكلة في انتضار البقية .

Hi. Do I have to replace also the camshaft sprokets every time when I fit new chain and plastic guides or is not necesary?

Very educative. My 1zz VVTi engine chain makes a rattling sound when accelerating, they recently worked on the engine but rattling sound when accelerating. What can I do to stop the rattling sound?

What brand of timing chain or set should I buy for my 1ZZ-FE? Thank you.

Hi, is it toyota corolla 1.4 or 1.6 ? and how much kilometer already run ? thanks.

Thanks for the video

Peter , I have an 03 camry 2.4 . 2az fe . Can I replace the timing chain and oil pump without removing the motor????

i have toyata yaris 2007 plz tell me after how many killometers engine chain is compulsary or necessary to chain

I have a doubt. The VVTi engine 2GRFSE is the same VVTi at engine 4GRFSE? The mine is damage and i want to know if compatible. Thank you

Excellent inspection Peter!

If I installed chain according to the mark if I rotate the engine will the mark aligned back or not thanks allot for the video

Hello, is there a gasket between the timing cover and the engine block? Is there some sort of sealant?

Hi Peter my 1zz corolla rattles when the engine runs for about 3-5 min,i changed the chain,tensioner,guides and some gears uper and lower,what can I do to stop the rattling or where is the rattling coming from??thanks

Hi, if new chain it's not installed right , may have a difficult start when engine is hot? On a cold engine starts good.

Great information 👍

What year make and model is this from? I have an 03 RAV4.

Hi, as you mentioned in 9:50, the timing chain rail which is plastic, can be worn out. My car has a resonance (Toyota avensis T25 facelift 1.8 petrol) around 2800-3000 rpm. It makes only resonance in speed, but not in neutral. Someone told me, maybe the tensioner can be worn out also and makes it resonating?

I have a ticking noise when car is hot. Also idle sounds like diesel car when it’s vvti petrol. Could it be bad timing chain. Also code P0016? Excellent video. Does engine need to come out or done while in car?

grat video. much appreciated

Must you remove the engine to make these checks?

Does the timing chain cover have a gasket, I got my chain replaced last year and my engine oil is leaking now I suspect that it's because of this.

Nice Peter👍😊

Hi my brother Peter. My engine 1nz toyota vios is start nicely but when I put on gear the engine has no power. So what is the problem..?

If the paint on the links are good and not faded out the timing chain is good. Toyota timing chains don’t wear out unless something else is wrong like the vvti cam gear or the tensioner.

Thank you.

Good and helpful 👍

Thanks! :)

Salut, pouvez vous m'aider à chaque fois qu'on fait la mise au point du moteur et on essaie de tourner le moteur sur place pour voir comment les cales de la chaîne vont revenir sur le même point de départ, ça ne marche pas. C'est à dire il y a décalage quand les arbres à cames arrive au point, le cales de la chaîne sont à côté. Noter : on avait procédé au changement de la chaîne qui s'était coupée pendant la marche et le pignon du vil brequin.

The boss good evening

Hi Peter, You have done a top job about the timing chain with this Toyota engine. I think the chain should still be OK. The chain pressure guide rails have worn out alright. I will examine the timing on my vehicle because my engine has problems misfiring at varying speeds, low to 2000rpm then at 3000rpm and above not as bad

2 questions about the chain. Could you just move the chain over one link and would the slack then be taken up by a tensioner? I was wondering about removing a link but I found out why that doesn't work: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Iuoa31xVah4.html

See? This is what I mean, very easy, even with two camshafts.

I realy greath too hear and lærning from they some knowing realy. I only have done it a cople off times,buth that eas before i get cander opereted in head in the 2005. Afther that i realy geth something like a work like this one a car ofice,buth something small work i doing. So i relaly know what you are saying. Greath to know that every one off use have something too learning.Buth like you say about the engine so i allredy listen ore read what you say and i know realy that you can mechanikk realy. I think you are a good mechanical. Greath day too you. Tommy

I got a question... what does it mean when the crankshaft is stuck... it can only go a 180° forward and backwards... but can't go a full 360° spin?

May I ask you how many miles or kilometers on that motor to have it stretch out that much? Because I have read of people getting to 500,000 k on factory chain. But my yaris has what I call a chirping sound when idling cold, but goes away when warmed up. To me it sounds like the chain is slightly rubbing. But I could be wrong, maybe it is a pully or bearing, I don't know yet. Thanks! thumbs up! What a great video. I've changed the chains on Nissan KA24e but this motor looks way better designed, with the tensioner accessible from the side like that. Toyota wins over Nissan, again!

Can the original chain go 300k miles?

Couple it right

Just cost me $2100 at the mechanic to have mine fixed on a 1.5ltr vvti Toyota Worth fixing though it's so cheap to run

I no how to do this one very well

Yes they are. Iff man only do it raight from the bigining,it allso alleays bee good in the end. Ekselent engine. I have one Yaris from 2012. I am greath with it. Only the aut in 110km.h,it is a little little tolate so it coes better in 120 ore 110. Thats wee allredy know. But i am happy with mine. Only shans oil every 10.000km so it bee greath. Have a nice day. Sunday. Good Sunday to you all.

👍👍

Iff the camshaft turn over the valve takes bad iff something happened there

You sound like Count Dracula
