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.

@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

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!

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.

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.

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.

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.
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 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.
thank you very much from France 🇨🇵
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.

It's somewhat rare nowadays to get a tradesperson that is both competent and ethical..
I took my 2016 Camry in for this very reason (when it was STILL under warranty) and was told not to worry about it (by 2 Toyota dealers). Now it is not under warranty and you mention this rattle IS a concern! 😡 I dealt with this sort of crap with GM and went to Toyota because I thought they were better... looks like they aren't. Disappointed to say the least...

@@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.

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.🙂

@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 )
