- A Toyota Master Diagnostic Technician Shares information on when you should fix your engine cold start rattle and more important things that are often missed when this repair is done
In this video we stop a job at the shop half way to show you what actually happens when rattling VVT-I gears go unfixed for long and what complications arise.
Also I share with you a criteria so you'd know when exactly to perform this repair so you're not doing it too early but also not too late where other damage can happen.

15:21 Why This Problem Happens - ยานยนต์และพาหนะ
Me: 2012 Camry LE 4cyl. Brief rattle on cold start up. Rattle started at 68k. Temporary solution to prevent rattle/damage until you sell car or fix (replace gear): Have a spare ignition key cut (from a blank without a transponder) Home depot will do this for $3.00. The key will open the door and crank the engine (won't start it). When car is cold, insert spare key and crank engine for 5 seconds. Remove spare, insert transponder key and start the engine. You are building oil pressure and sending oil to the gear without starting the engine making the rattle less noticeable or eliminating it. Again, only a temporary solution to help reduce potential cold start damage.
As an Assyrian Christian from Iraq, I love all the work you do, and it makes me so proud someone from my country who is a Christian doing all the best he can do to succeed is succeeding while at the same time putting his faith in his work and his religion and sharing it to the world. I am completely proud of all the progress you’ve made throughout the beginning of your channel. May the Lord bless you and keep you too!
AMEN!!
With all due respect, unless most other Assyrian Christians are scam artists, what does the religion have to do with anything? I don't give a sh*t about jesus or religion in general but I have pride in my job and integrity like my father thought me. That's all you need to do the job honestly and correctly.
👍🏻👍🏻
Everyone should be able to speak what's in their heart. If its positive so much the better.
Great Comment!’
Best ability a mechanic can have is to diagnose WHAT have happened, and WHY.
Thank you AMD for your honesty and knowledge.
Understanding is everything
Yeah
Car Care Nut you are my hero. I have a 2013 Rav4 AWD with a 2AR-FE engine. Rav4 has just over 80k and has the noticeable cold start rattle. I'm an ASE-certified mechanic but left the auto industry long ago to work on aircraft instead. Your attention to detail and experience give me the confidence to tackle these types of repairs to help my Toyota live a long happy life. Thank you.
just curious why you changed to aircraft stuff? better payment or do you enjoy turbines lol? I am almost in the same path as you, thanks
We're not working on chevys. 🤣
Shots fired!!!😂😂😂😂
@That V8 Life that’s not really a valid argument though. Let’s be real here. Unless you’re going with a GR product, you’re not buying a Toyota because you want an “ impressive “ car. You buy it because there’s a solid chance that it will literally outlast almost every other brand you can compare it to. Having a “ fun “ car stops being “ fun “ when it starts breaking down unless you either have enough money to throw at whatever issues keep popping up or unless you have enough money to just throw the whole car away and buy a new one altogether
@That V8 Life What are they?
@That V8 Life okay, and?
@@shyro76 I have a friend that has replaced his transmission and engine already in his Toyota. Prior to that he had other major repairs. Anyways , he drives his car like a rental. So abuse a car and it will wear down faster.
I have been a mechanic for 30 years, I have replaced more than my fair share of GM 3.6 chains, that's why I buy Toyota and Honda as daily driver
Your customers are so lucky to have you as their mechanic
If there was a bridge connecting my country to where you live, I will drive for miles to come to your autoshop. Reality is that Trusted mechanics are rare to find. May the Lord bless you and your family, your Autoshop as well 🙏
Absolutely fascinating. I’ll never attempt this, but it’s wonderful to understand how some things happen inside the engine. Thank you so much.
Ditto
I don't even own a Toyota but I still watch his videos all the time!!!
@@dmbfannh Yep my family, locally, owns 6 Toyotas (2008 to 2021) and I maintain and fix them all…this channel gets watched a lot!! AMD is a blessing!!
Double Ditto. I really appreciate AMD's thoughtful way of explaining things and advice.
I wouldn’t attempt this job either. Not like changing a starter lol.
A cheap fix that worked for Me. AMD is a true Toyota Master Diagnostic Technician indeed. I have learned a lot from this Man's videos, and much appreciate his contributions to You Tube. I have a 2011 Toyota Camry with the 2.5l engine and Have been listening to this "cold start rattle" for years. Watching this video at the 15:25 section, where Amd disassembles the vvti gear, It appears , when it gets oil pressure, the rattle stops and there was no real wear as a result.. So, in the fuse panel by the hood release, I located and removed the 8th fuse, a 15 amp labelled "INJ" ( I assume this shuts off the fuel injectors). I engaged the starter for 3 seconds, shut the key off, reinstalled the fuse, started the car...and there was .NO RATTLE..I have tried this 3 times, with the car sitting for 5 days at 1 point, and there has been No rattle on cold start up. I have devised a set up, so I do not have to remove the fuse each time , so I can engage the starter for 3 or 4 seconds without the engine starting, before a cold start. Please note: I am NOT a professional. Please consult a "professional" before attempting this procedure.
@user-cq5wt8ir6m, I hope you see my comment, I love AMD’s videos to educate myself before tearing into my car, but you really have my respect! Thank you for sharing what you tried!!!
I love your passion for doing a great job on Toyota product, keep up the good work and keep the videos coming.
It truly is impressive.
Love your honesty and integrity doing it right 👊🏻👍🏻
What I like about this channel 👍 is the attention to detail as well as the brilliant advice and the reasons that the faults develop in the first place.
I have great respect for a mechanic that does this job in a PROFESSIONAL manner and not shaft the customer in the process. I would never attempt this repairs myself but I learned a lot watching this video.Thanks, AMD for this video.
It's somewhat rare nowadays to get a tradesperson that is both competent and ethical..
This man is proud of his workmanship -- a rare quality AND owners get value for their money.
Well done sir -- a man after my own heart !
By the way, I would love to see the "Design FMEA" that *should have been done* by Toyota engineers for the top guide -- they should have identified the likelihood that the tab would break and found a way to prevent that occurrence.
I did the procedures on my 03 2.4 L 2AZ-FE without pulling the timing cover. BIG MISTAKE. No matter how hard and careful I was the timing was off and when I started it it sounded like a sewing machine also the new gear was damaged and had to get a new one. I did go through the lock procedure. I redid the job and did the timing chain, guides, dears, sprockets, and tensioner. The chain was also stretched by 1.5 links. I did replace the guides because they fell apart a soon as i took them out.
I have just replaced the intake gear on my 2013 Camry which I purchased a few months ago. Car has done about 60000Km. Australia. After analysing the one-second rattle upon cold start, my definitive conclusion that the noise was coming from the intake cam gear. The original gear part number was 13050-36030 and all the dealers here in Australia told me that there was no updated part number. Hoping that Toyota would have fixed the original problem 10 years later, I went ahead with 13050-36030 again.
I spend hours carefully disassembling and assembling all the required parts by following T-SB-0041-13. Installed all the seals I encountered on the way. The top chain guide was like brand new, but I still replaced it. I even had to unlock the gear once as there was not enough slack to put the chain over the installed gear. Followed the gear unlocking instructions from the TSB. Succeeded at first attempt, miraculously! HAHA I had to put the chain over the gear before installing, torqueing and locking the gear. Had to keep tension on the chain at the same time. This was the hardest part. Just didn't want to drop that chain.
After all that, the rattle is still there! You just don't understand how disappointed I am now! Is there an updated part for my Camry? In Australia only 13050-36030 is listed for my car. I can see that the TSB mentions 13050-0V040, but I was too afraid to deviate from proper part numbers for my car. Is there an updated / improved part for my Camry?
Of course, I cannot thank enough this channel!
Love learning and love your honest approach to keeping toyotas running
This is the best ever walkthrough and detailed explanation of the cause of the VVTI cold start rattle I have ever seen. You are worth your weight in gold going through all this in meticulous detail. Makes all other video attempts I've seen instantly redundant on this topic, especially the fine detail about not locking the new VVTI gear until it's been mounted.
We had the cold start rattle on our 2002 Celica for a few years (never lasted for more than a second or two on startup) and in May this year we took it in for service for this exact issue. The mechanic got the entire kit. Timing cover kit, new chain, new chain tensioner, all new guides, new VVTI intake gear and all the gaskets to complete the job.
Some items may not have needed replacing but we replaced the lot because really how often would we open the timing cover for this kind of service and there is no point skimping when it comes to the timing system on an interference engine. We probably wont ever need to do this again.
The Celica has no more cold start rattle The car has done over 300,000 km, burns very very little oil and drives beautifully.
Great video.
How much did all that cost to fix?
@@whoknows8678 About $1,100 AUD
@@arthurgiannakis2156 Ouch. That sucks for what I consider to be very likely a design flaw. Even TCN was talking about the VVTi gears like they were a bad design and caused timing chain issues.
Thank you for this video and your dedication and commitment! Learned a lot today.
This is exactly the video I am looking for. Thanks for sharing. 😁
Thanks again AMD for sharing your wisdom on this important information 👍
Really helps to understand how it works. Great job!
Every one of your videos, I learn something new and worthwhile 👍🏻
Your skills set never stop amaze me. Now because of you I have better understanding what happens inside of the engine every time I am driving my Toyota
Love watching your videos, you explain things so well, definitely a great mechanic and a Toyota Guru 👍👍👏👏
Cheers
Bluey
Best mechanic show ever
Great work !!!
AMD, Thanks for the stability of your guidance on this important issue 😁
I'd love to see a complete, start-to-finish video for this job. From what I see here, you haven't reached the part where a diy'er like me would be in over my head or need too many new tools that I'd only use once or twice. It's a common enough job that lots of people would watch a how-to video from the best Toyota mechanic in the world, you! I'm a real fan.
same
me too!
one of the best automotive maintenance repair videos on TH-cam.
Another very informative video AMD! Currently own 2 camrys a 2012/ 2014 and had not seen how these parts work or fail. I'm a tooling technician by trade and work on my cars so this is very doable for me and thank you for explaining in detail!👈👍
The vvti explained so everyone, mechanically inclined or not, can understand how it operates. Thanks for sharing this.
Much respect, and thank you for the detailed explanation. I've spent hours on different videos trying to figure out what else I need to replace on my mom's 2009 RAV4 besides vvt gears, and you just nailed it. Now I can go to sleep 😁 good luck to you man!
Thank you AMD you carefully explained alot of the mysteries !
Legendary we are not working on chevys and bmws😱😱so true master
Oh how I have learnt so much from Mrs Car-nut and Yourself Mr Car-nut!
She puts the camera right on the spot in Question and you do your work. I love watching all your vids as I was a older mechanic for years but I'm still learning. Thanks for putting out these informative vids and may the lord Bless and keep you both and family so we keep getting these wonderful vids! Thanks Again from Australia.
Aussie chris. 🇦🇺
Great video! The lighting under the hood was perfect.
I love this channel! Too bad all techs are not like this gentleman
Getting ready to do this job myself. Just got my genuine Toyota VVT gear. Came back to watch this as a refresher. I always enjoy these videos.
Best advice: Thanjs so much. Our world should have more people like you:
Disregard the negativity. I see all my favorite channels dealing with the negativity. You are one of the best, forget about these keyboard mechanics. Keep up the great work. If you are hiring, I’d move to work for you. I’d be grateful to be in that shop, even run the floor scrubber and take out the trash to be around a master like yourself.
The only Toyota You Tube channel you need !
Thank you AMD. Was not aware to lock the gear once installed.
LOVE the new camera! New guy quickly becoming a professional photograher!
Thank you for putting out this informative video. I have a 2AZ-FE and it has this issue. With over 220,000 miles, I'll definitely need to do this job.
You’re telling me pretty much what my mechanic told me so this makes me feel a lot better about still driving the car. In that second stage of when you should fix it but I should have the money next week. Thanks for the video.
He is absolutely right. I just had this fixed on my toyota rav4 2011.
Again. AMD knows his stuff. I like his shop. Nice and clean and good high end tools.
You're an awesome tech!!!! awesome knowledge and craftmanship.!
For me it' s a pleasure to assist to your explanations and videos. Thank your very much.
Amazing content as always. Really well done and super interesting,Thanks!
Excellent video. Fascinating. I really liked your discussion about what can happen if you just ignore this problem. My wife's car (not a Toyota) has been making this exact same startup noise for years. I'm hesitant to spend the big bucks to fix it. The noise has never really gotten worse (so far) and I listen for it all the time to make sure. Now I have a much better idea of what kind of risk I might be taking -- whoo boy! The car is a 2011 Elantra. I've heard that the noise can also be due to a faulty timing chain tensioner.
I've never seen before where someone takes the time to *explain* why things happen, and the consequences thereof with VVTI. Thank you and greetings from Prague. Czech Republic
Wow - the Hercule Poirot of Toyota repair videos. Absolutely superb, sir.
U are so dog gone interesting!! U know, if ur back gives out, u could always be a professor/ teacher! That engine is IMMACULATE!! CAN'T believe how clean cam/ head looks. Once again, thank u!
It is very rare to find a mechanic like this I mean as well as being honest watch how he handles his tools smooth no roughness anywhere even when pulling apart the vvt gear the vice handle gently gets put back a true craftsman
Well explained well filmed
I really love watching this guy amazing and so true while Toyota s may not be that exciting customers quickly get over that as they do thousands of kms of trouble free motoring
Looking forward to the next video👍
Thank you so much my Brother, I learned a lot, God bless you much more!
Great video! Thanks for the detailed description of the failure points!!
Excellent video!!! Straight forward and informative. Thanks so much!!!
This video was extremely helpful! I would never attempt to do this type of work as a DIYer, but man it helps to know the little details watching someone who knows what they're doing taking it apart. I bought a 2011 Highlander yesterday and have checked it out carefully and test driven it... But not from a cold start. I'll know Friday when I pick it up if it has this problem, and if so, how far along in the problem it is. I feel that someday I'll have to fork over the dough to get this job done, just a matter of timing the decision based off of the level of deterioration... If there's any.. funny thing is I decided against getting a Honda CR-V for a similar known issue with those, called VTC actuator. Almost identical symptoms. I didn't research the highlander as thoroughly because in my experience, the only things that break on Toyotas are parts that break on ANY car... Engine and transmission are usually not even something you'd have to think about. I guess it's not all that bad, knowing what I know now, and I am better prepared to assess it if / when it comes, and not just freak out (or even worse, get comfortable with living with it) like I would have otherwise lol. Love your videos keep em coming! Thanks!
Thank you for making this video. I’m in the middle of replacing the timing components on my 06 Scion xb 1.5 1NZ-FE and I received a 8 piece timing kit that was supposed to be new and when I opened it up the bag that had the VVT gear in it had been cut open and it immediately threw up a red flag to me. I started to send it back right then and there and now I wish that I would have because after watching this video I learned that the gear was locked and if I hadn’t watched this video I would have definitely tried to install it and then I would have blamed myself when the whole thing went bad again. That being said I am forever grateful to you for your expertise and experience with this product.
I have a 21 year old Tundra with 160K miles. I don't have any significant problems (but there are some minor ones). It would be a blast to have it checked on your YT video. Your shop is only a 4 hour drive. It would be totally worth the time.
@stdigitalmemories dam your Tundra is barely broken in. 160K miles is not much for a tundra. Scotty Kilmer had a 2000 model on his channel with 400K miles, & it even pulled an 18,000 pound trailer for 400 miles. Pretty incredible. Those old tundras are bulletproof keep your frame rinsed off & your truck will last you a lifetime
@@Blakecryderman7244 Toyota replaced my transmission for free at 75K miles and they replaced my frame at 110K miles. I replaced the exhaust and manifolds not long ago. I have some minor issues with the 4 wheel drive not always locking, otherwise it works great. Thx.
@@stldigitalmemories that is literally like the first time I’ve ever heard of a tundra transmission going out at such low miles. You sure you take care of it? The 4WD not always locking, that is usually from shifting into 4WD after not moving the shift lever for years, and the truck won’t be used to it. The old saying goes use it or lose it.
@@Blakecryderman7244 Thx. The dealership told me transmission issues rarely happen, but they do see it and I was lucky it was still under warranty. The dealership was paid $12K from Toyota for the frame replacement. At 110K miles, they broke a lot of bolts and I ended up with new shocks and misc mounts. The truck is my weekend vehicle mostly for hauling things to/from my ranch. Every couple of weeks I swap it with my daily driver to give it some exercise.
Glad I came across this vid my 11 Corolla 1.8L started making this noise recently only for a second tho , I originally thought it was the starter.
I've been heading this on my wife's Camry for a few years now but didn't think much of it.
I'm glad you said "this is not a Chevy." Because it does sound like hydraulic lifters getting pumped up at cold start.
Thank you for this. We'll have to find a dealer because I'm not comfortable doing this in the yard.
Thank you for sharing this AMD I've got a 2013 Toyota Camry with 100.000kms and have had the VVTI Rattle since new at cold start. I will definitely be looking more into Replacing The VVTI Gear ⚙️ in the near future. Thank you and God Bless 🙏
Love your channel. Best there is. Learned so much. Much if way above my head but still…gives me confidence when I do go into a wrenching project I haven’t done before. Currently have 04 Matrix XRS with 255k miles (still runs like a bay out of hell but timing cover gasket leaks like a screen door on a submarine…will one day get the cajonnes to attempt that job). Other car is a 04 Vibe 1zz at 189k miles. Love em both.
This Video should be used as Instruction Video for Toyota Car Technicians and people who work on Toyotas.
Great explanation and i hope my Toyota with the 1NR- FE won't be in such a trouble in the future but in case i know what to do now.
Best regards from germany
And he got a vvti video..thanks for the o2 sensor video! I learned everything I need from that video 👏👍
Just bought a 2009 Vibe, and this was an incredibly useful and educational video for the issue I'm facing. Thank you!
What was yours doing? I just bought a 2009 Vibe too and it sometimes has trouble starting for the first few seconds, then smooths out. I think I might also be hearing the rattle when it is struggling. What did you end up doing?
Yes I learned something again. Thank you so much !!
I used to have a Lexus IS300H (2AR-FSE) and the sound always annoyed me… The dealer didn’t had any idea what it was (‘ah sir, it’s a product feature’, that’s the standard comment these days), but now everything is clear!
Big compliments for your knowledge and patience… You’re TH-cam-channel is superb!
I really love the pride that you put into toyotas...!!!
I work on diferent brands and toyotas are my money maker...!!!
Another great education thanks for all the wisdom
Very informative. I have a Toyota RAV4 6cyl with 220,000 miles haven’t come across this issue but have had other issues that I have gotten fixed
I have a 2009 2zrfe, rattles extremely rarely. So I understand that I do t have to be worried about it until it becomes more frequent and occurs at every start. Thanks for the informative videos AMD. I learn a lot from your channel !
Great video, I have a 2014 Camry with 38k miles with that engine,it sounds just for 1 second, I'll be monitoring it.
What a great day! I plan to do this on my boys 13 rav4 2.5
My '09 corolla does this every once in a long while. Definitely going to keep an ear on it for now.
2011 Chrysler 3.6 penstar. I have been looking for this solution video for 5 year's..
Thanks much love ❤️.
Watching you work and explain things is always a singular pleasure.
Ugh, sounds like I am gonna be spending some money soon. My 2010 Rav4 has 203k on it and has had this issue on every start since I bought it 30k miles ago. Thanks for being so detailed with every step and the surrounding issues related to the repairs you are demonstrating.
You're completely right about Chevys!
Fantastic video. Thanks!
Thank you for this very well presented informational video!. It helped me get my brother's VVT sprocket replaced the proper way and with great results.
So clear explanation of things! Fantastic!!!
I would do this repair in a heartbeat if I ever have a VVTi failure, thanks to you, AMD.
How many hours will you take ?
I would definitely be glad that You checked it.
I agree with you on the chain that doesn’t need replacement, like literally everybody will be saying , replace the chain . For what . Been a Lexus tech for 7 years now , never seen a chain failed
AMD, thanks for the channel and all the great information. I have had success on 2008 avalon 315k miles cold rattle. changed valve cover gaskets and oil vvt seals on valve cover. Rattle gone! 🎉 Thank you for sharing!
I have owned three Toyotas over the years and now my newest one a 2011 4 runner only has 88,000 miles. I wish there were someone like the Car Care Nut had a shop near me.
Love your videos! you have such a soft and pleasant voice.
thank you for this valuable lesson my friend...things you showed only experience will know
Thank you very much for sharing your videos ❤
Best American made vice you have there, Wilton has been around since before WWII and known for their quality.
I just noticed this rattle on my wifes Prius yesterday morning. I watched the video, and my wife just took her prius in to the dealer today. Thankfully it's still under warranty!
Excellent video Ahmed.
This video is very useful, my Saab has similar engine design, it use timing chains with guides and tensioners that look very similar, minus the VVTi, it is very simple, almost like Toyota.
GREAT Show.
Very informative video. Good to know what I need to watch out for. Thanks.
Very interesting! Thanks!!! Good vid!!
