When Should You Fix Your Engine Cold Start Rattle | Important Things That Are Often Missed

[@postedinthecut1565]

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.

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

[@StromBugSlayer]

I have a 2009 Vibe with the 1.8 engine. On truly cold starts (like the car has sat overnight) the car will start right up - no problems. If it has only been sitting an hour or two though, the car will struggle to start. I don't have to keep cranking, but it will stumble and falter until it really catches, and then will smooth out and behave normally. During that stumble and struggle I will hear the VVTI gear rattle just very briefly. On normal starts I do not hear it at all. Possible suspects: 1) dirty throttle body 2) Mass Air Filter sensor 3) fuel pump 4) VVTI gear 5) Spark plugs / coils 6) clogged fuel injectors. Any other ideas? I'd appreciate anyone's opinion and advice on how to diagnose for certain.

[@zeehng5736]

@@StromBugSlayer scan for any error codes, which might indicate issues with sensors like the crankshaft position sensor. Start with a load test on the battery and an inspection of the starter motor. Replacing an old starter motor often resolves heat-soak-related issues. it may be worth testing the fuel pressure to ensure it’s holding steady.

[@shyro76]

@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

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.

[@arthurgiannakis2156]

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.

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 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.

[@Blakecryderman7244]

@@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?

@@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 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.

[@robertomulero514]

Perfect timing for this video. I just heard the cold start rattle for the first time on my 2010 Vibe with the 1.8 2ZR engine with 98,000 miles. It hasn't done it for the last 5 cold starts but I guess I better start saving. My main problem is finding a mechanic that can do the job right like you. I wish I was closer to Chicago. Good idea to just remove the timing cover to do the repair even though you don't have to since most times it's leaking anyway to do the job right.🙂

[@Blakecryderman7244]

@Robert Mulero wow 98,000 miles on a vibe. Not very much. You must only drive it in the city. Before you fork out $200 or so for your Vibe’s cold start rattle, try something. Buy a bottle of ATS oil system cleaner, & pour it in your engine oil, & what it does it get rid of carbon, nitrogen based cleaner. It’s not some snake oil seafoam crap, it’s actually good. But what it actually does to fix the rattle is one of the reasons it rattles is because the tensioner gets gummed up with dirty oil, & it takes a second for the tensioner to do it’s job correctly, & the ATS oil cleaner gets rid of the build-up. Give it a try, it costs $30, worth a try before spending more on an actual timing cover removal teardown etc. ATS ( automotive test solutions ) is sold by Burney ( I might have not spelled his name right ) In Albuquerque New Mexico, & they spent 8 years testing what ingredients get rid of carbon the best inside engines. In order for you to more know about it, look up Scotty Kilmer, he’s a mechanic with 53 years experience, works from home, & he has a couple videos showing how you use it for your car. It worked for him when he was working on a 2007 Volkswagen Rabbit with a noisy engine. He explains it better than me, which is why I recommend you watch his video on it. Worth spending $30 to give it a try, not that expensive, & it can make the noise go away after pouring it in the engine oil & have the engine revved up to 1800 RPM for 20 minutes, then after that it will have circulated around & have done it’s job. So yeah, $30 for the bottle. Watch Scotty’s video on it, & give it a try. Wish you all the best. Cheers, Blake ( I also have a 2006 Matrix )

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!

[@64arguz]

I did it exactly as you did and I have exactly the same result, my case is worse, I bought a second one pulled out the spark plugs to turn the engine and lock the phaser , I even took pictures to be sure in my mind before installing the valve cover that the phaser was locked, after spending $500 + in parts the stupid rattling is still there 😡, as soon as be possible I’m going to try the “timing cover off” option, this is the ONLY complaint I’ve of my car 🤦‍♂️

@@64arguz After replacing the camshaft adjuster with two different part numbers 13050-36030 (car's original part) and 13050-0V040 (part number from TSB) and still experiencing the cold start rattle, I decided to replace the chain tensioner as well (I have no idea why I didn't replace it when I replaced the adjuster!). Well, I'm happy to report that the cold start rattle has disappeared!!! I still don't understand why I replaced the camshaft adjusters before attempting to replace the chain tensioner as it is a much cheaper and quicker option! I was probably swayed by numerous reports on WWW on this cold start rattle solution. Also, while repeatedly, carefully listening to the location of the cold start rattle, it obviously came from the intake camshaft adjuster location - even after replacing the adjuster (TWICE!).

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.

You're talking about a 5-6 hour labor charge vs. 15+ hours of labor charge. Toyota pays less than 3 hours for the job under warranty.

@@CamKrazy2000Maybe you can answer my question then. I have a 2012 Camry Hybrid. 2AR-FXE. I’ve had the cold start rattle since I’ve owned it. Bought at 93k and it has 258k now. I’ve seen videos where people say it’s just the chain tensioner. Why have some people fixed the issue with just replacing that? Also, I found out the chain tensioner for the hybrid is inside the cover, so not as simple of a replacement as the non hybrid engine. Thanks for the help.

[@CamKrazy2000]

@@ryandhaley2 There is no difference between the hybrid and the non-hybrid engines as far as the set up. The cam gear rattle on the 2AR has been around ever since the engine was first introduced in 2010 or 11. Most times replacing the intake cam gear fixes the problem but I've seen the cam gear break apart a couple times. If you've lived with it for that long, I wouldn't worry about it. Just make sure you have enough oil because oil consumption at that mileage isn't uncommon.

I found 2 solutions to my 2007 Corolla vvti rattle. First solution, I added 3-4 oz of Seafoam to the crankcase and that stopped the rattle. The Second solution is the one i am using now on a permanent basis, I have switched to 0W-30 Mobil 1 FS oil. My Rattle is gone for over 6 months now.

My 95' 3RZ made a huge knocking noise on cold start ups if any torque was applied to the engine before an ample "Ample!" warmup. For years it was necessary to warm up for about 15 minutes for best sounding startups and drivability. After the rebuild, this was no longer an issue. It was sure nice to not have to worry about that any longer. It did this for over 200k of its life. I thought for sure it would spin a lower bearing if not properly warmed up every cold morning. I'd go around oiling things, with all the white smoke from the icy morning blowing, kinda reminded me of bring a steam engine to life at the start of my commute.

I owned two new Toyotas and I didn't keep them very long. The first one was a 2000 Avalon. It was in the shop for two weeks because of an electrical problem after I had it for a very short amount of time they had to call in the factory text to sort it out. Sold it with 26,000 miles on it, didn't like the ride particularly was kind of floaty. This engine has suffered from sludging Up I didn't own mine long enough to find out. Traded it on a 2002 Honda Odyssey which was great until the transmission started going bad it's a common problem. My next new Toyota purchase was a 2007 Camry which was the first year for that model. I only own that till about 25,000 miles. It was burning oil and the factory wouldn't do anything about it. They subsequently fixed others when the complaint started piling up but mine was one of the first ones built. It also had a drive-by-wire system electronic throttle that was dangerous because it didn't respond right away when you gave it gas. Frightening to drive when you needed to get out of the way of someone else. Traded it on a 2009 Honda Accord, other than the rear brakes which are unknown problem the car never gave me a bit of trouble and use that for 80,000 miles and bought a 2014 Honda Accord which has been a pleasure to own. I know many people who own them for a long period of time, and you can see old ones commonly.

Another great video. I have a Gen 3 2GR-FE. I have changed the oil and filter in my Avalon every five months since I 've had it. I want to especially thank you for making us all so aware of the few shortcomings this engine has. Mine has the all-steel VVT oil supply lines. I opened up the upper banjo fittings and the filters were pristine. I also pulled the VVT solenoids, and they were pristine as well. This engine is very quiet and so far, no leaks of any kind. I just appreciate your videos even if they don't apply to me. I have 82,000 miles now, so My 50,000 mile coolant change is coming up. Thanks again.

Do all that just for the rings to stick 3 weeks later. No particular reason why. Coolant fine, never over heated. Just rings started sticking. Oil changes every 3-4k. What’s even better, when that top guide gives way, makes the motor sound like it’s thrown a ride or something. Gotta by the whole timing set for that one bracket. Also be weary of the timing guide that the tensioner rides on. It broke on me asw. Fun stuff.

[@truthseeker9026]

I wish I could’ve found my brackets that fell of. Mine got destroyed I’m sure. Pulled the oil pan with the procedure to find that bracket, never did lol. I love that you have made these videos. I’ve experienced all of this. 2.7lvenza. Now it needs a new block, as I foreshadowed earlier.

AMD, would you consider making another Lexus IS video, but this time specifically on preventative/periodic maintenance? Maybe include what history has shown to be considered chronic problems with the IS and how to mitigate them? I have a 2022 IS 500 F Sport Performance and it would be selfish for me to request an IS 500 FSP specific video, but maybe center the video on the 3rd Generation IS w/plenty of specific content you've learned about the IS 500 FSP engine, transmission, cooling system etc over the years from the RC F & GS F that may apply. BTW, I'm in Houston, TX and have lamented before on the fact you have no plans to open a shop in the Houston area. But I have found a Lexus only independent shop (actually two locations in Houston) that reminds me of your "Mission Statement", experience and passion for Lexus. For Houstonian Lexus owners, they're called "Clear Choice" Lexus Superior Service in The Woodlands and The Galleria. All of their Specialists are Lexus master mechanics, only use OEM parts and add their parts warranty on top of the Lexus warranty.

When SAAB changed timing chain manufacturers around 1994 the chains started BREAKING with great regularity on the 2.3L 4cyls DOHC. We got shipped some tools along with a bulletin to address any noisy, pre-broken chain. It specified to remove the valve cover and CUT the chain between the sprockets, hook on a new chain to the old with a master link, and PULL the new chain through, then attach the master link. I worked for dealers for 20+ years, that stands out as one of the silliest factory fixes I ever ran across. I think I only did one of them like that, but probably 200 more the 'right' way. If the chain was damaged/noisy, I would always find the guides damaged as well. In fairness, that engine was absolutely excellent otherwise. In 4 years I only saw 2 lower end failures, one drank in some water when customer tried to drive through a flood (bent connecting rod), the other had been run out of oil and driven a very long way. I wasn't a fan of the cars at the time, but looking back, fond memories, as I learned a lot and met a lot of cool people in that company. SAAB Tech support was initially ONE guy.

[@MrMarcus5191]

My well maintained 2011 Camry has 98000 Kms....about 60,000 miles. I am thinking of a workaround to avoid the rattle on cold startup. I think the rattle originates when the oil drains out of the intake VVT gear on shutdown. Possibly there is a way of priming the gear with a slightly longer cranking time using the engine oil pump This can be done by delaying the fuel injection circuit enable by about 2 seconds after starting to crank the engine over by inserting a time delay relay into the fuel injection circuit. I am going to try this soon when I have time...will keep you posted. Thanks for the information, much appreciated....! (edit)...Have been experimenting during our cold snap...pulled ' EFI MAIN ' under hood fuse and cranked engine for about 3 seconds....replaced fuse and engine started quiet as a mouse! Sure supports theory that oil is draining from VVTI gears on shutdown. (edit 2 ).....Back to square one, returned to stock configuration. Added Rislone Hyper-Lube to thicken oil....good luck so far...

[@zainulabideenzain3]

What causes this to get damaged? And how to prevent this in new car? Can there still be this rattle issue in new car which is will maintained? Or this occurs only if the car hasn't been maintained properly?

[@jeancassel]

Issue came with the original design of the vvt gear, can't escape it, but strict regular oil changes can significantly delay this from happening, or potentially not happen at all. My corolla (12 year old) does this rattle every now and then on cold start only. What's interesting is as soon as I do my regular oil at change 6months or 5k, it does not rattle anymore until about 4-5 months in.

[@jeancassel]

With new cars, Toyota updated the VVT gear, so might as well consider this fixed.

[@TheCarCareNut]

This is an issue with design. 2014-2015 and up got updated parts already and won’t have this issue. This issue can happen to the updated parts with heavy neglect on oil changes

Hi & thanks so much for posting your great Toyota experience. I have 2 questions for you concerning Toyota’s VVTI issues on my 2018 RAV4. Since the car was brand new I 1st changed the oil & filter at approx 1200 miles & then every 5k miles max using M1-0w/20 winter(I live in northeast) & 5w-20 summer. Fast forward to today the car now has 48k miles on and is now making the cold start VVTI noise for approx 1-2 seconds max every time it’s started but i can only find a Toyota service bulletin/T-SB-0041-13 dated 3/5/2013 only covering 09-2013 RAV4 VVTI issue and can’t find a VVTI tsb for my 2018 RAV4. Do you know if there was a bulletin specifically put out by Toyota for VVTI issues on my 2018 RAV4 & if yes please give me the tsb number or link to it. I looked all over online in mult places & I found tons of Toyota tsb info but not specifically for my 2018 RAV4 that I need to have to bring to the dealer before I pass the car hits 5yrs old in a few months in 1/2023 when the 5yr & or 60k Mike warranty runs out . Also, I have seen where some people have posted they replaced the timing chain tensioner located on rear of motor and doing just that stopped the cold start VVTI rattle noise,have you seen that too & if yes what’s your take on it? With that said my question here is since my RAV4 only has 48k miles on it do you think the lower miles would hopefully mean the timing chain guides would not be cracked or broken yet to where I could get away with just changing fairly inexpensive easy to replace chain tensioner & forgo having some dealer wrench going deep into the motor where they could cause other issues down the road,leaks etc? Thanks….Scott 11/15/22 Update. Dropped my RAV4 off again at Toyota dealer to have their regional Toyota diagnostic tech along with my files s top tech cold start my car to hear it rattle just like it does in this video & guess what? At 1st they said it doesn’t have the cold start rattle therefore there is no need to address it. I then showed them the cold start rattle in this video & then showed a video I took of my cars cold start making the same rattle/rap noise gir 1-2 seconds then quieting down. Then they changed their tune saying well we now hear something of a cold start rattle but it’s not enough to warrant repair at this time & refused warranty work a 2nd time. The std warranty coverage on my RAV4 is 5yrs & or 60k miles,whichever comes 1st and my cars age hits the 5yrs mark may1st 2023 but is currently at 48,850 miles so ok on the miles portion of the warrantee. Not happy with Toyotas response to the cold start VVTI rattle issue my car has esp since this is a known issue with mult Toyota motors since at least as far back as 2007 as far as iv’e seen & maybe even before that. When Subaru had burning oil issues a few yrs ago I know 2 people that had approx 65-70k miles on the Subaru’s they bought new doing 5k Mile oil & filter changes & burning 1qt oil every 750-800miles & Subaru installed new short blocks in both cars no charge which greatly reduced oil use to then 2500-3k miles per qt oil. Thanks a lot F-ing Toyota for not fixing my car you know has the dreaded VVTI issue that I will have to either d std pens $2-3$ y to I fix properly at a later date or forced to buy a new car considerably earlier then I had planed. I will never buy another Toyota product after they knowingly blew off fixing the known VVTI cold start rattle issue they heard my car do! I planed to get at least 150-200k miles out of my RAV4 doing 5k oil & filter changes along with also doing trans,coolant & rear diff srvc’s every 50-60k miles max too. I already initiated a customer complaint with Toyota cust Srv’c so I will call them tomorrow to update the complaint with Latest info of the district rep & Toyota tech both hearing the cold start rattle but said it’s not bad enough to do anything with yet meanwhile my car gos out of warrantee 5/1/23! Good job f-ing Toyota! Thanks for listening.
