Was quoted 2500 for parts and another 2500 for labor. Got all new oem parts for 1140. Thank you for taking the time to make this. It was very relaxing and enjoyable to watch. Kind of like the mechanics version of Bob Ross
You rock. My FJ cruiser has the same motor and the timing cover was leaking. After watching your video, the chain was stretch and the tension was pushed out with the rings identical to your vehicle. I followed your video to the second and my truck it up and running better than ever with no oil leak. The coolant housing is leaking slight which is weird since I put a new oring in it. either way it is better than the oil leak and I have a new timing chain thanks to you!!. I would never want to do this again though. It took me over 20 hours but I am no mechanic only a DIY. either way it did save me around $2000.
VERY Nice main timing chain explanation and install. Very much appreciated that you made a comment that it make take several revolutions of the crank to have the alignment of cam shaft links and crank link come back into alignment. Toyota and many other manufacturers are very good with visual assembly aids. In this video I was a little surprised that the crank link was the same color of the cams, but you did very well to balance the chain and orient correctly. Thank you for sharing your talent. P
LSmiata, thanks for watching! It is possible that the OE chain would have had different color links. The chain used in this video was an aftermarket. If I get a customer that buys an OE chain i'll have to take a look! Mike Becker, Technical Services Instructor
Thank you for all the tech testing procedures they help me to be a better mechanic all around good to have thank you. Now as far as the timing chain job I did one of them on the same 4.0 engine and unless I am starving I won't do another one what a job wow thank you again John p
Hey Hoopty_Medic, thanks for watching! I make em so you guys can watch em'! You keep watching, I'll keep making videos! :) Mike Becker, Technical Services Instructor
That's a great setup there and I noticed you had an engine sitting there in the corner. Another great video Mike you are on a roll. I sent you an email about the known good few days ago. For some reason my business account didn't show the video was up. I wish I had a garage that size I do my work mostly outside when I'm working for my business otherwise in the shop for the boss. Thanks for doing this series Robinson's Auto Diagnostics
Thanks, it works for me at home! I can't not get my hands dirty every once in a while. That is a 2.5l Ford motor. Same exact problem that Eric O's Escape had. Burned valve on cylinder 3. I chose to replace it with a 80k junkyard engine. I wanted the old one to hopefully do a class on it at some point :) I did get your email. I'll get you that known good at some point next week. I have to find my flash drive that has them on. I changed laptops recently and they aren't on it. Mike Becker, Technical Services Instructor
Wells Vehicle Electronics Appreciate it and yeah I have seen that problem in the transits as well with the 2.5 apparently it's common for #3 cylinder which I find odd but that's the one I see with bad valves.
Tip:On the small new cam chains, the painted timing marks should face backwards so that you can see both marks after everything is installed. If installed facing forward you will only be able to see the exhaust cam chain mark. I enjoyed your well documented video, thanks for sharing
I did a cover on this version of the 4.0 and I don’t remember taking the oil pan off/ I do remember removing the 2 studs from the lower part of the block that protruded through the cover. I remember cleaning it very well and making sure no dirt got into the oil pan
Nice work Mike. Great tips along the way. Some lucky DIYers will now have a sweet 4.0 chain swap video for reference. Looking forward the the final analysis. Thanks!
Amazing knowledge and expertise on this trade, really impressed. I have the exact same vehicle with just under 150K miles, been getting oil changes every 6-7K miles, full synthetic oil, hopefully I never see this kind of issue with my 4R, seems like lot of labor cost!
Hey Reg Park, thanks for watching! I hope you never run into issues as well. This was a big job. Keep changing that oil! :) Mike Becker, Senior Technical Services Instructor
Reg Park .....my 2007 4Runner SR5 manual recommends oil change every 5000 miles and use conventional 5-30 oil. That’s what I do, what does your manual recommend? That’s what you should go by.
My friend for you to do 6 to 7 k you will need redline,amsoil or ravenol oil otherwise you will do this job .Try Mobil 1 every 4K and you won’t have a problem
Those red/yellow links need to be lined up with the phaser dot. You have to turn the engine over until they all line up can take a dozen or more revolutions till they do.
Nice work! Enjoyed the video! One thing I would add is it's probably a good idea to soak the chains in a small tub of motor oil. That keeps them from galling on first start up and while waiting to get oil bathed while the engine runs.
Hey William, glad you liked it! I needed something to cover up the frustrated profanities spewing from my mouth :) Mike Becker, Senior Technical Instructor
I just had my timing belt changed at 178k miles. That was 6 years ago. I’m now at 204600 miles in 2024. I have a perfectly wonderful 2003 Toyota Highlander
Hey William, thanks for watching. I'm confused. If the chain were spot on why was the check engine light on before and off after? Mike Becker, Senior Technical Instructor
At the beginning of the video you were wearing the loosest paint stained yoga pants Kohls sells. I wasn't jealous.lol Nice job with the details on the timing chain. You do a few of them on the same car and it becomes cake, a real learning curve. On to episode 6 now for me and another cold beer. Cheers
Hey 29 Auto, it depends on where you get parts from. I'm not going to discuss pricing on here. Best bet is to check with your local store. There are tons of advantages to DOHC. Power, efficiency, emissions...etc. Mike Becker, Technical Services Instructor
Watched this over 2 nights and I’m very impressed, not only with your mechanical skills but your camera work. Some really good quality footage you got, felt like I was there stood at the side of the car! Looking forward to the final part :-)
Hey man, can you please edit your comment to remove the profanity. I appreciate the comment, just trying to keep the channel as clean as possible! Thanks :) Mike Becker, Senior Technical Instructor
I have 2007 FJ that just came home with this error code. No abnormal running but as you clearly explained this P0016 code is not going to go away. Disappointed with Toyota as only 140,000 miles and always maintained well
Ugh Robert, sorry to hear that! If it's any consolation, once the job is done you should be set for the rest of the vehicles life...as long as you put in good parts. Mike Becker, Senior Technical Instructor
So I cleared the code a week ago and code hasn’t reappeared. Plan on doing a Seafoam treatment with hopes that helps. Car has been well maintained and always used AmsOil. Vehicular runs strong and doesn’t miss or hesitate. Repair shop quoting est 18 hours because of oil pan removal.
I have the same engine and got a P0016 code. I replaced the sensor but no luck, I removed the sensor and used my bore scope and could clearly see the exhaust sprocket phaser was 80% gone. I opened the small inspection door below it and just so happened this broken phaser was hanging on a bolt so I fished it out - LUCKY!! Do you know if this sprocket can be replaced by just removing the valve cover and not taking the entire timing chain cover out?
Great video, Question: my kid ran her 05 4runner out if oil. Not sure for how long. But it started to throw P0345 and P0345. After a full oil change service I pulled both cam sensors. The driver side had a thin groove. Seeing your video it is clearly being hit by the sensor wheel on front of crank sprocket as pointed out on video 33:24. After replacing both sensors one of the two codes went away. The other im guessing is that side with the damaged sensor. Could that wheel pickup have become loose due to no oil pressure? Im dreading doing this service. Albeit pretty mechanically inclined. Any insight is appreciated thank you
Hard to believe those chains were so stretched . I thought they would last a lot longer. I had a 1980 Toyota Pickup that had over 400, 000 on it before the transmission went out , and it also ran better then the new six cylinder Toyota I was considering buying before it died .that was a good old truck.
Honda K- engines have had this issue particularly with customers that followed Honda’s 10K oil change interval. That Yoda has also experienced extended oil change intervals based on the varnish I see. Oil & filters are cheap... even if you use premium quality oils & filters.
Great video of how to do it at what mileage does Toyota recommend you replace the chain guides and tensioners only 4.0 I'm getting ready to purchase a 2010 Tacoma TRD sport double cab 6 foot bed for will drive and it's got 89000 miles on it I was just wondering what Toyota recommends what miles to change this at
Hey Willie, according to Toyota the timing chain is not a maintenance item. It should last the life of the vehicle. I believe it would/does as long as the oil changes were done at the correct intervals. The only time you should have to go in and replace the chain and tensioner is in the event of a failure/check engine light. Mike Becker, Senior Technical Instructor
I'm not a mechanic, so forgive me if this question should be obvious: I understand from your explanation that the chain stretched and the tensioner compensated as far as it could go, but *what caused the chain to stretch in the first place?* I'm trying to avoid whatever causes a major $$$$ repair like this for my 4.0 V6 Tacoma. Thanks.
Hey Michael, no need to justify your question...it's a good one! Stretch is kind of the slang term of what happens with the chain. In all reality it is actually wearing. This wear makes it longer, hence "stretch". 2 major factors play into this. Oil change maintenance and OEM timing system design and components. Some vehicles are just prone for chains...looking at you GM 3.6L and Ford 3.5L Eco-Boost! Best thing you can do is keep your oil clean. Regular intervals, 3-5000 miles depending on driving conditions. Mike Becker, Senior Instructor
@@GoTechTraining youre not wrong about the 3.5s we have multiple every week come in with stretched chains. working on one right now that was 30 degrees of timing, should be low low around 0.
Great video.Now to my question.I'm going to change the timing chain kit on Kia inline 4 cylinder 2.0 16v "G4KA" engine with phaser on the intake cam only.I'm confident the job will work well.My only doubt is about the so called "slack".I never did a timing belt/chain before.Where should i have the slack before i releas the tensioner pin -- between CAM2 and CRANK on the chain or between CRANK and CAM1 on the chain(where the tensioner is).It's a pretty standard inline 4 cylinder with 2 camshafts engine.
Can I ask is it really necessary to change the chains if they are just stretched? Outside of the annoying code light can’t you still drive the vehicle with just a stretched chain??? Thanks mark
Hey Mark, that's a great question. Chain stretch is chain wear, eventually that wear will become to great for the tensioner to take up the slack. When that happens the chain will become loose and likely jump a tooth/teeth. If this happens, many engines will slap the pistons into the valves causing catastrophic damage. So, in short the trouble code is a warning to IMPENDING DOOOM within the engine lol 😆 ~Mike
Is a 2010 4runner 4.0L V6 a belt or chain? Looking at buying one and there all high 150k plus miles. Can't find any video's or info on them. It will need replaced if not already. Please reply
Today's engines really are all very similar in design. I feel like newer engines are easier to work on that only 90's or early 2000's motors. What do you think? Mike Becker, Technical Services Instructor
Wells Vehicle Electronics the nissan 3.5 came out early 2000,I had a 01 nissan pathfinder, it is dohc ,vvt,and water pump is driven by the timing chain, lol
Good stuff. Those older 3.5's are good engines...except, aren't those the ones with head gasket issues? Where they leak coolant externally on the back of the head? Mike Becker, Technical Services Instructor
Thirsty but they put out good power...so it's a good trade off? Better than being thirsty like a 4.0L in a Ford that is lacking power! Mike Becker, Technical Services Instructor
Hi I’m just wondering if you have to replace the two big gears at the top of the cam. Is it something you could look at it inspected if they look OK just use those or do they need to be automatically swapped out with the chain? Thank you very much for your help. Mark
Hi Jay, The cylinder head does not have to be removed, the front timing cover must be removed to replace the timing chain tensioner . Hope this helps! Thanks for watching. Ryan W Technical Instructor
Great video! I just stumbled across this as I am planning to replace the head gaskets on my 2008 4.0L V6 4Runner. I bought the car with 206k miles and it now has 295k. The engine has never shown any engine codes while I have owned it. Recently it started loosing coolant with no visible leaks but after inspecting the cylinders and pressurizing the cooling system, I found #4 and #6 to be leaking coolant. The car is still running fine with no check engine light. Aside from replacing the head gaskets, do you think I should replace any other components while I am in there? E.g. timing chain, etc. ? Thanks!
This thing had about 140,000 on it. What do you mean stained? Many engines look like this when they're up there in mileage. I think the root cause of the chain stretching is a lack of maintenance.I think the oil change intervals were too long, this caused wear on the components. MIke Becker, Technical Services Instructor
No real verification from Toyota on the root cause. If I were to venture a guess it would be just poor quality of the chain design. I've seen it on well and poorly maintained vehicles. Only seems to happen on 4WD models... Tacoma and FJ Cruiser. I guess when subjected to higher engine loads via pulling a trailer or offroad use.
Cory, in this case with this code there is no way the phaser could cause the issue. If you're dealing with a different code and wanting to verify phaser operation you could drive the phasers with a scan tool and see if the engine changes. You would then want to look at phaser position desired vs actual. Generally the phasers are ok, it's the oil flow or oil control (VVT) solenoid that is the issue. Mike Becker, Senior Technical Instructor
Best repair video I've ever seen. I have one question, though - what do you use to hold the crankshaft pulley in place while loosening the pulley set bolt (and tightening it upon reassembly)?? I'm struggling to get mine off and don't want to damage the pulley doing so.
Hey Charlie, thanks for watching!! I didn't use anything to hold it in place. The crank pulley should stay steady due to the compression inside the cylinders. You should be able to get it loose but it requires an impact. You most likely won't get it with a rachet. Mike Becker, Senior Technical Instructor
@@GoTechTraining Good to know! Thanks for the reply. Since I've already taken the spark plugs out, I'd imagine that I've lost compression and wouldnt achieve that again just by plugging them back in...
Charlie, throw the plugs back in, tighten them down and then the motor wont spin as easy. I bet you'll get the pulley off that way. Mike Becker, Senior Technical Instructor
Another method for a really tight crank pulley bolt is to use a breaker bar and socket on the crank pulley bolt and having the breaker bar up against a solid part of the vehicle i.e. subframe rail, and then using the starter motor to crank the engine for a short period to loosen the crank bolt. Note that this method comes with risk of damage to vehicle components such as transmission cooler lines, wiring, body or whatever else could be in the way, caution and preparation need to be used, you also need to be familiar with the vehicle i.e. does the crankshaft pulley bolt have a left hand thread. IT ALSO COMES WITH THE RISK OF INJURY IF YOU DO NOT KNOW WHAT YOU ARE DOING!!! I have used this method too many times to list in the field when no access to air, impact tools or a method to hold the crankshaft from turning is available, without problems. Care must be taken!
Great Video! Its giving me some confidence that I could have fun doing this myself! Its an 07 FJ and the symptoms are exactly the same as this one. Runs good. No noises just the 00016 code. Where is the best place to source the parts though? Thanks!!!!! Love the tutorial!
Hey Jason, not too sure that i'd call this job "fun" ahaha! I went aftermarket on this one. Depends on how much $$ you want to spend. Mike Becker, Senior Technical Instructor
I'm currently doing this on my 06 Tacoma (1gr). there is a HUGE difference in pricing between a timing chain kit from the dealer and an aftermarket kit(150 vs. 800). What are your feelings on going with aftermarket vs. dealer on this particular part? Thanks in advance, and thank you for this video.
Great Job Mike. Just one enquiry: Did you put an OEM timign chain or an aftermarket piece? If coul be an aftermarket part, wich one would you recommend. I have the same model but from a 2003 Year. Kind Regards
Hey Antony, thanks!!! I did use an aftermarket chain in this. Cost was the main driving factor. I do not have any recommendations besides to say that you should buy one from a reputable manufacturer. Thanks for watching! Mike Becker, Technical Services Instructor
How many miles on the engine? One thing I noticed on the teardown is that the left cylinder bank looks a lot dirtier than the right cylinder bank...I would expect them to look pretty much the same!
Hey Brent, around 140k on this one. The left bank does look slightly dirtier. I would expect the same as well. I think this entire problem stems from a lack of maintenance. Oil change interval was too long with the previous owner I believe. MIke Becker, Technical Services Instructor
Hey Sergo, thanks! I like fooling people into thinking I have patience ;) I would not call myself a patient person by any means, but thanks anyway! Mike Becker, Senior Technical Instructor
Roy, I can send you the torque chart, sure. Shoot me out an email to me and I'll reply with it. MCBecker@ngksparkplugs.com Mike Becker, Senior Technical Instructor
Would you consider the internal of that motor to be in good condition? My 1GRFE has 120k and no where near the level of varnish and burnt spots on the valvetrain and so forth.
Hey I'm about to do this on my 2007 FJ cruiser (same engine, I believe). Are there any gaskets you need to replace on reassembly? I'm trying to have everything ordered before I tear it down.
Hey Brandon, it's been quite a while since I did this job. Intake and valve cover gaskets for sure. Not sure what else from there anymore. Mike Becker, Senior Instructor
@@GoTechTraining a mechanic in town just told me that for my '07 FJ, the axle and oil pan had to be dropped. You didn't do that in the video for the Tacoma. Is there something different about the FJ, or was he mistaken?
Great video, Mike. Thank you for taking the time to make it. I am current throwing a p0012 code on my 05 4Runner 4.0L. Has just shy of 250,000 miles on it. At the end of this video you state it was throwing a p0016 code. Question is, would the fix be the same for both of these codes? Trying to save some $ and capable of doing the labor. Just don’t have the tools for a sure fire diagnosis. Thanks!
NGK Technical Training- thank you! I did have a small oil leak from the passenger side valve cover a couple months back that I fixed. So that may have thrown the code. CEL is still on so I will look into the VVT solenoid. Thanks again
@@GoTechTraining the mechanic said it was correct? But well I wasn't there when he did it. He's supposed to open it up again. Do u have any other tips or pointers? I have some pictures if you would like to see?
Great video. I just bought an 03 4Runner Limited with 200k miles. I was just curious what the symptom was and how bad it was since it was still drivable? I will definitely subscribe. Thanks for helping so many people to maintain their own vehicles. Sean.
Hey Sean, thanks for watching. The customer complaint was an intermittent check engine light and slightly lower fuel economy. Really nothing else. The customer didn't realize the truck was slightly lacking power until after it was fixed up and was back to its self! Mike Becker, Senior Technical Services Instructor
awesome episodes with excellent info one question when u look at cam or krank signal is the signal will be zero to 5 volt or will be between zero and 5 v lets say zero to 2.6 v and so on. thankyou and cheeeers Mike.
J Georges, thanks!! It really depends on the car. A cam sensor is generally a 0-5 volt wave, and crank signals can go either way. Analog, or a 5v signal. There may also be some that are on 12v. Look at a diagram before scoping. That should help! Mike Becker, Technical Services Instructor
Poor maintained engine (oil changes) is usually the cause. If you keep good clean oil in your vehicle, it may run for quite a while without developing chain stretch. ~Ryan
I have a 05 Tacoma with the 1gr-fe timing chain seems stretched timing is the same as this video before repair. But I'm not getting a p0016 or p0018 I'm getting misfires on bank 1. Have you seen a stretched chain that has misfires but no timing code? Thanks
Hey Tanner, that seems unlikely. Generally the timing correlation code sets before a misfire. I do suppose its possible...but I would probably take a look at the VVT solenoid/phaser for that bank. Could be your issue if it's a single bank of misfires with no correlation codes. Mike Becker, Senior Technical Instructor
i am about to do this job on my 2005 Tacoma. Should I be worried about replacing the vvt cam phasers as well? The dealer listed them as an item they were going to change. Do the sprockets wear over time or just the chain?
Hey man, the phasers add a pretty significant cost...If you are planning to keep the vehicle long term I'd suggest doing them...why not, right? you're already that far into the engine, might as well replace everything that's there. You may want to do the oil pump right away too. I did not replace them on this engine to help control cost and the vehicle is still on the road today problem free. Mike Becker, Senior Technical Instructor
The oil pump on these 4.0L's is mounted into the front cover. It's not a ton of extra work but it will of course add some cost to the job. Mike Becker, Senior Technical Instructor
Hey, sorry was out of the office for a week...Looking in service info it does not say the bolt needs to be discarded...so i'm going to go with No, not torque to yield on that one. Mike Becker, Senior Technical Instructor
Eric, I know I mention it in the first video in this series...if memory serves correct I think it was about 140k on this 4.0L. Mike Becker, Senior Technical Instructor
@@zachattackhzachattackh7054 my 2007 1GR-FE 4.0 is currently at 241,000 Miles with no issues. original timing chain!!! It's all about maintenance. keeping those oil change intervals at the manufacturer's recommendations. Fingers are crossed! hopefully mine will go 300,000 or more.
ken H It’s also reliant upon the quality of the oil. FJ uses the same basic engine and as of 2008 they still required SF grade oil for them. SF has a significantly higher level of zinc/phos than current oils. The problem is finding SF oils. The only mass produced one I know of is Royal Purple HPS . I’m sure there are others. Mobil 1 0W40 European Car formation has more zinc than their other variants.
Hey Mike. Great video. I'm not a mechanic by any means. I have this code with my '07 fj cruiser. I've been jotting down questions as I watched the video, so here goes: How long did the job take you? The FJ Cruiser basically looks the same under the hood, but the book time to do the chain on it is 22 hours. For this vehicle you said 10 hours. It looks like you did not use a complete timing kit? You reused the old cam sprockets and phasers? Where could i get the service steps/procedure documents that you had? Is there a such things as variable valve timing controller... or just the solenoids (or are they the same thing)? would you recommend replacing the solenoids? How did the repair hold up?
confused about your video. You stated at 27:29 that the cam should line in the center of the two phaser marks. But at 1:02:35 you put it back together like it was before. did it run ok afterwards even though time was slightly off? Still a great vid though.
They are both good engines really. Timing belt requires maintenance. Timing chain only gets replaced when there's an issue. It's really a personal preference. Mike Becker, Senior Technical Services Instructor
NGK, I need your advice. I have a fellow working on a blow head gasket. After he repaired the head, he didn’t put the timing back on properly. So the engine would not crank. We are at a stand still, now the compression is low. He think the chain is still on wrong. Can you please give me a hand.
Hey 1911Breeze, When you say the engine won't crank, you mean it won't even turn over? Timing won't stop the engine from cranking over...unless the pistons are hitting the valves. If you mean it won't start up, well then, yes, you could have the timing off on there. Mike Becker, Senior Technical Instructor
Great video as always Mike. Timing always makes me nervous. Good to see I'm not the only one who gets their gloves dirty, not their hands. lol. Nice home setup you have there. You told me you sold the Mustang so is that a new toy at 8:00 under the blanket? All the best Mike. Thanks for taking the time to share your knowledge and experience with us DIYer's.
Mike, timing makes everyone nervous I think. One wrong move and the motor could be junk...that's hard. I always check a million times, but the first turn of the key I always hold my breath. I'm a glove wearer. I'm surprised I didn't see more comments on it. I find that my hands get cut up less with them on. I like to keep my blood on the inside haha! That was the Mustang. This was shot back in July, before the car went away. Thanks for watching Mike! Mike Becker, Technical Services Instructor
I'm doing this exact job right now. At 1:27:49, while you are doing test rotations, I see both the chain going around the idler sprocket suddenly slacken, as well as watch the no.1 tensioner move in and out throughout the rotation. Are both these things normal? This is my first timing chain job. I expected the chain to stay evenly taut throughout the rotations, however just after passing TDC, the chain slackens around the idler sprocket just like it does in yours. I half expect it will be slapping against those guides whilst I'm driving. Any guidance would be appreciated! Great video, been super helpful.
Hey Brett, the tensioners aren't pressurized at that point. They are just using spring tension. Once the engine is started they fill with oil pressure and hold the chain tight. Hope you get the job done successfully! Mike Becker, Senior Instructor
@@GoTechTraining This particular 2GR has 110k on the chain and gears no evidence of lubrication issues. But the tensioner is pretty far out. After multiple attempts I cant get the marks to align. They are about 3° of cam timing off. I'm currently awaiting parts to arrive to correct it.
Jeremy, looks like you're correcting the problem before any other issues are caused by it! Well done. Nice to stay ahead of it! Mike Becker, Senior Technical Instructor
@@airjer18 Any experience with VQ engines? They seem to have timing chain problems too, more so with the guides themselves. My VQ40 has the infamous timing chain whine. 158k.
Wells Vehicle Electronics yes I’m looking at it now but never have taken one off before. I wonder if I could send you a picture of it for advice. Thoughts? Never taken a fan clutch off but have a crack case seal leak so I need the fan and shrowd out of the vehicle. I’m hoping that that the crankshaft pulley is Keyed and not pressing onto the motor. Any info or help would be greatly appreciated. Thanks!!!
Andrew, sure you could send me a pic if you'd like. Michael.Becker@wellsve.com The crank pulley is keyed but the bolt can be very tight and hard to remove. Good luck! Mike Becker, Senior Technical Instructor
