‼️⚠️Correction in the video! The RTV silicone bead goes just outside of the groove, not in it. Place the bead on the flat mating surface between the groove, but inside of the bolt holes. The groove is there to catch the squish out when the cover is reinstalled. ‼️⚠️
Should remove the dipstick also, seen it get pinched between the cover and upper oil pan if you reinstall it with it in the tube.
@@lacrease6517 yup!
@@MrSubaru1387 can't someone like FelPro make a real gasket set for these engines?
Glad I read the comments. 😳

Hi
It really makes me appreciate these engines. Incredible build. Thank you for showing this
You sir are a wealth of knowledge. You are good at what you do.
You’re 100% right I searched for hours before coming across this video! So helpful and very well done! Thanks a lot
By far the most comprehensive video on FA timing chain R&R available that I can find. I'm in the process of rebuilding one of these engines right now and I wanted to find something clear and understandable by a professional tech. Thank you!
This is also such a good guide for EE20 diesel variants (the chains start to go anywhere from 140000km upwards. Engine removal in diesel is not required for diesels btw, you can get away with fans out and bottom splash guard off if you take your time. You will know if your diesel chains are due if it stalls on cold starts and disconnecting the cam sensor cable stops it happening (it will throw a code and limit rpm, not drivable)
Now I know why I love my old EJ257, life was so simple back then, proper gaskets are my hero.
You are a walking Subaru Service Manual. An excellent job on explaining engine timing chains removal and installation. Nice tips on how to use silicone sealer, where to use it and how much to apply. When reinstalling parts with O-rings, why don't you put a little engine oil on the O-rings? I would think it would help them seat better between the two parts. Seems that three or four alignment bolts besides the dowels would make it easier to install the cover without messing up the silicone placement. Thanks for another great video!
Awesome job showing us the ins and outs of the front end
the best youtube mechanic.
Ya him,car wizard, car care nuts and Ford boss me.
@@zachsummers3321 No way car wizard is going to be mentioned before Eric at South Main Auto.
*Scanner Danner is typing…*
I agree.
@@supermotos Eric the car guys deserve a mention. ( Rev up your engine aka mr bad hair day get a perfect rotten tomato 0%).
Hey Mr. Subaru I watch you on a regular bases. I have a 2018 Outback 2.5 touring. I don’t know what it is if it’s a ej aj if it has a belt chain I have been out of the shop many years can you please inform me. I fixed small airplanes
in the army and served in Vite Ñam 1969-70. I use to fix cars too but can’t remember what I had for breakfast. I tried to do tire rotation. Once I got the tires off I could not get them back on without help. I am old and decrepit. Any way I like your youtube videos. Reminds me when I use to fix things. Pay no attention to those negative comments lots of haters out there. Have a great day keep up the good work. 😊
An '18 Outback has an FB engine with a timing chain.
IMHO, if you're going this far to change the timing on this engine unless it has been done recently, it would be a good idea to reseal the cam carrier also. And labor wise, I'm sure if you're doing the cam carrier, it's a good idea to just do the timing stuff anyway or do a good inspection
As someone who has the rattle on cold start, may be worth changing tensioners while you're in there, depending on how much they are.
Great look at the FA/FB timing chain setup and servicing. Not a DIY project for anyone but a car mechanic, and not even a service I'd be confident of getting done right at a dealership with their "factory trained" technicians. There's a lot more that goes into doing this service right than knowing your nuts and bolts, as MrSubaru clearly explains.
thank you so much, pulling the engine next month myself at a privately owned shop I work at. Noticed the same lack of quality videos with thorough explanation bc I've been trying to research how to do it for months now hahah. This video along with my mentor at work makes me extremely confident in our success :) going to be replacing valve seals as well as I believe they're starting to leak
mr.subaru you are a god i love you. ive been doing an fa20 build for my car and the other night i was trying to get my timing cover on and i kept hitting the side of the cover on the cam gears and getting rtv on them and it was annoying me. even tho ive put these covers on quite a hand full of times i still just couldnt get it, you showing me that they have these alignment tools just gave me a bright idea to basically make my own out of old/spare bolts and my trusty dusty welder hahaha thanks mr.subaru
anaerobic sealer like Locite 518 or Permatex 51813 is the way to go with these timing covers or cam carriers. it is much easier to deal with and has zero chance of plugging anything up. i hate RTV the only thing i use RTV on anymore is tins.
This! Volvo makes a great one too
How easy/hard is it to get undone for the next repair?
Is it comparable to RTV during removal or might it increase chances of breaking the cover?
@@thewiredfox2691 it comes apart no problem.
Yess I greatly appreciate this. I am in the midst of replacing a cylinder head, and intake cam. Found one of the rockers broke free during a clutch and engine reseal job. No check engine light of any noticeable mpg loss, nothing.. But Im kind of new to the cam clearances and adding the correct caps the the rockers. Ill get it done. But I do appreciate the timing chain video. Ill take all FB20 videos. THanks
How many mechanics do you think will immediately grab a sanding disc do exactly like Mr Subbie said NOT TO DO. That’s why if my shit needs work I’ll take it down to him. It’s an 8 hour drive but worth it.
Thank you. Planning on short block for my 2012 Forrester, refurb the heads. Torque sequence is funky though.
Really enjoy the channel
Between the timing chain and timing belts I do prefer the timing chain cause they are lifetime and you very rarely have to change timing chains they last forever but… the simplicity of the timing belts and maintaining them and changing them is a lot easier than dealing with this timing chain setup.
19 minutes in and I'm already glad I have a couple old EJ253s...
The Toyota 2.7 2trfe has a very similar oil pump design. I did the head gasket on my Tacoma and it wasn’t easy. Head gasket went at 235k miles. Ran good when I finished it but ended up going and buying a 23 wrx which seems like a really cool car. I had about 40 hours into that head gasket. Pretty much what Toyota calls for to fix it.
The labor to do this right - assuming I can find anyone competent- would be so expensive Im thinking a new Factory engine swap might make more sense. 🤔.
As long as you change your oil regularly, you shouldn't have to change your chain. The serpentine belt after 100k miles is another story.
Thank you for blessing every Subaru owner now i know what i have to do With the engn
Awesome vid! This helped a lot, I have to fix a little leak on the bottom of the cover.
I'm a Honda guy who is converting to Subaru. I used to think boxer engines were intimidating, but this is a dream compared to cramped transverse engines.
They are. The rtv is a pain. If you arnt extremely careful its debri can cause lots of issues. Most mechanics won't be so careful
Obviously they're not as sharp or durable as steel razor blades but I've found the plastic razor blades can work well for removing RTV sealant on aluminum because you can be more aggressive without worrying about scratching the aluminum. Just make sure you have plenty of them because they won't last long.
I always thought was very similar to EZ30/36. Since it looks like all the main design elements come from EZ36(angled conrods)
Great detailed video! Curious why Subaru would choose RTV over a gasket.
Cost...
RTV works better than a massive gasket for the timing cover.
There be dragons! The late model 2011 Forester with the NA FB25 (first generation) dos not have VVT on the exhaust as mentioned in the video. The LH intake cam will be under tension to align the marks. The service manual does have a bulletin, however I found them to be less than clear. In the end, the timing marks do line up the same.
Having a 2018 Outback 2.5 Touring for a few years now, I hit upon your channel and it is IMMENSELY informative. Can you comment on the small battery dilemma ( class action lawsuit )? I live in Canada and my car has sat quite a bit during covid in the last few years. It gets to -25C (-13F) during winter in my neck of the woods. I NEVER had battery/starting issues. I looked a replacement choices if I need it. I am told that the type 25 can be replaced by a type 75. Some youtubers have suggested type 24. They are obviously larger. The battery blanket is, of course, smaller. Is there a bigger one? All youtubers did the cut/patch method. Can I assume either the 24/75 can do the job? Thanks
As always - you are awesome! Thanks for the knowledge
I took my frs into dealer with p0018 code. 3 weeks later they told me the camshaft had broken in half. He thought this because when he relieved tension the camahaft moved. Had them put back together took too another mechanic that tried starting it. Dealership didn't do valve timing after reinstall, and now the motor wont fully free spin with crank, fml. Any advice on the motor? Just sell it as valves prob hit the pistons? You are my new favorite mechanic btw
Really great content. It was a bit funny half way through your calming voice reminded me of Bob Ross.... I think, on these longer videos, you might be the Bob Ross of car care.
Can’t seem to find a video on doing just the rocker to head gasket? This is a good video though thanks
as much as I love your channel this is a Hello Subaru Service dept! job for this guy. Still love how you teach us about our Subarus
What was the change interval for the FB25 engines? Ive got a 22 outback. Not something Im thinking about now but couldnt seem to find out if there was a change interval for it
Chains are lifetime. No service intervals.
Sorta suprzed that chain guide isn't bolted on one end...on the tentioner side... maybe the front cover holds it....
I know this is old but hopefully you still get comment notifications from it. What causes the timing chain tensioners to not get oil pressure to cause the rattle? by 2016 outback sounds just like that and usually with an oil change it gets a lot better. do oil deposits just get stuck in the tensioners? I want to do that but i'm worried about the cost since it seems engine removal is the easiest way to do it and at that point i'm sure there are a lot of other maintenance items to do "while you're in there"
Hi, this timing setup it's also for ee20z diesel engine, because timing kit I order is also for f20 engine. Thanks
i have FB20B engine and when i start it morning its sound is high but when the oil warm up its sound goes down so what is its problem ?
Excellent video! Thanks Mr Subaru!
Thanks!
Thank You!
Hopefully you see this. How do I take the chain off when my crankshaft is spinning freely
This was a great help but im getting P0018 on the Left side intake.
For the crankshaft mark, the front(or right side) is clear to me where the link should sit.
What is your reference point for the rear ( or Left) side?
I noticed there's a mark on the back of the gear i could use or does it go on the same tooth in line with the visible mark of the front(Right) side?
i suspect I may be a tooth off but it does run.
Is the right and left chain the same?
I know this is a little off subject but it seems they have discontinued the OEM alternator for my 2006 Subaru outback. I oem part number is 23700AA55A I am looking for the best quality replacement? Can Mr Subaru or anybody else knowledgeable point me in the right direction? Thank you.
Use good oil and filter, change at specified intervals. Simply the best insurance for your engine
What an awesome video!!! Thanks for sharing and posting!! Happy Memorial Day!!
Excellent video, everything is very well explained in detail, just one question: is the chain not checked to see if it is stretched or if it has looseness between links?
Great information,,a lot of interesting details
If there is any question one might have warped the timing chain cover, is it better to just go ahead and bite the $400. cost for a new one?
You do a good job you would make a good teacher
Explicação bem detalhada ótimo pra entender , parabéns e abraço aqui do Brazil
Grind a small groove and fill it with paint on the outside of your crank socket to correspond with the key way, that way you know where the key way is all the time. Great video! Thanks! What RTV do you recommend?
Hey there, currently putting back together by FA20DIT after building it with forged internals and all the goodies. I'm doing the timing and followed this video to the T as well as following the Subaru service manual information regarding the timing assembly and every sixth or seventh full rotation of the crank is producing a ping sound that almost sounds like a valve hitting the piston. Threw a bore scope in my cylinders and I'm not seeing any damage to the pistons that would indicate timing failure. Any idea what could be happening or what I missed before I tear it all apart again?
Great video! I am not a mechanic so the answer is probably obvious to most. What is the reason for lining up the coloured links to the marks? is the chain not the same all the way around? Thanks
The colored links help you establish the correct relationship between the two cam shafts and the crankshaft.
how do you take off the heads?
Do these engines bend valves when a tensioner fails and the timing jumps?
Any chance you can provide more info on that chain tensioner rattle? How serious it is, and7is it normal for it to make that brief sound at startup and only an issue if the sound of lasts longer than the brief second or so after start up or does even that indicate the problem that I would require what looks like a major service?
Its pretty normal to hear with age. If it lasts more than a second or so, likely time to start thinking about tensioner replacement.
I pulled my 2.5rs engine out. Then realized my impact doesn’t have enough a$$ to loosen the crank bolt? Any tips on getting this off when the engine is on a stand?
@MrSubaru1387 regarding the PCV system, is it more beneficial to run a catch can/AOS on the F series rather than trust the PCV valve? I have a 2022 Crosstrek 2.0
Do you have to remove the engine from the car to do this fix? A friend of mine took her Forester to the dealer, and they told her it was going to cost $11,000 because they had to pull out the engine.
Under what circumstances or mileage requirements would you be replacing the timing chain?
Do u have a video on the 2019 Subaru crosstrek 2.0 f4 non hybrid engine timing marks?
What about using anaerobic sealant instead of RTV? Then you would not have chunks of dried sealant roaming around inside the case.
Thanks for the videos. You the best ❤.
what do you mean its not 41 or 42 allan head bolts holding the chain cover on... (still have nightmares of that 3.0L cover)
Спасибо 🤝
I have a question for a 2007 Subaru Tribeca B9 if you could help. H6 engine
Cant find the part number for the oring behind the tensioner. Would you mind sharing that?
I have not seen a removal on the chain section for the 11 forester. I have only seen the belts. I do have a question about the rocker arms since I am doing the heads on this one.
Hi Mr Subaru, nice video!!!!! Thanks!!!!!!
Is it too expensive to leak the 2015 Subaru XV 2.0i-S (AWD) G4X MY15?
When I went back together my LH INTAKE cam sensor plate moves freely from the sprocket is this normal or do I need to replace the sprocket?
Whats the typical lifespan or maintance schedule on the tensioner and chain?
Question! What can happen if the chain is too tight? Instead of one click it is 3?
What do you recommend for a DIY mechanics tool set? Thank you have a nice day Sir.
Screw that...bring the EJ engines back.
Thanks for the information
I was not aware that Subarus use chains I thought all of them still have belts. Do all of the current Subarus use chains and when did they stop using the belt setup?
Any chance you could do a video on cam carriers for the FB?
Motorcycle mechanic, I spend more time cleaning stuff than anything else. No doubt.
Man what a great video, thank you! 🙏
PLEASE!!!!!!! Does anyone know the part number for the injectors on the FA20 brz engine that are located UNDER the intake manifold!!! THE ACTUAL FUEL RAIL AND HARDLINE THAT RUNS ACROSS! Not the ones ON the intake manifold!
Great video thank you, question, Can these tensioners fail? Does it sound like a rod knock when/if they do?
Question:
My drivers upper cam phaser is barely off before removal. Double checked the markings and chain and it was good. Is my phaser going out?
Appreciate you. Great video
A quick question, bye the way I truly appreciate your detailed explanations. Having replaced a short block on a FA 20 2019 WRX turbo I would like to know what your best practice would be in priming the oil system prior to firing the engine. Hope your enjoying SEMA, spent 20 odd years as a manufacture ( Flowmaster) there. Looking for some insight
Question..can you change outer seal for the oil pump drive seal without taking the timing cover down? I have a oil leak behind my crank pully😢
Is there a sign when a chain needs replacing? Or will it throw a light before anything catastrophic happens on the road.
It looked like there is a casting bump at every pry point as an indicator where it's safe to do so.
Caveat to everything, 'uness you're in the rust-belt'
im doing this job and im having isssues with one of the cam phasers that keeps shifting position. is it gone bad?
This video is a lifesaver! About to go replace my intake camshaft sprocket on the passenger side but have been super nervous about doing this. Quick question though, if I only replace that one sprocket and use special tools to keep everything in place, I wouldn’t have to reset timing would I?
It’s probably a good idea to go ahead and reset the timing because if you get it all back together and the timing is off, you’ll have to take it all back apart again and do it anyway. Plus, if it jumps timing again, it may screw something up
So I'm gonna be getting a 2005 Subaru legacy 2.5l. I'm not really a Subaru fan but it's the best thing I can get to cart my newborn around in. It has a slight rod knock I guess so I'm thinkin of putting a 2.0l motor from a Baja in it cause I know those motors are more reliable. Will the 2.0 bolt right up to the trans and everything in place of the 2.5l?
Is there a recommended interval on the newer timing chains? I was under the impression that they were "lifetime" chains barring some other issue
They’re lifetime. Only replace if there are issues.
@@MrSubaru1387 thanks
Lifetime is, of course, subjective. Most car makers consider lifetime to be 100k-150k miles. Every part on a car will wear if you drive it long enough. Chains can stretch, guides can wear or break, tensioners can go bad.
@@jeremybirdwell2623 I’ve heard lifetime in Subaru terms being 300k miles for chains. That said I’ve seen FA/FB engines reach well past that without chain issues.
@@MrSubaru1387 Greatvto know as I have a 2014 OB with 172k and a 2014 Forester with 85k. I was able to do the timing belt in an old EJ20 with v the ringing still in the car. I seriously doubt that’s something I want to do with an FB.
Would you say the engine should be out? Also are there any milage intervals, where the chains, guides and tensioners, should be replaed?
Hi, I am from Malaysia. I did asked 2 of the workshop mechanic and both of them told me Subaru engine is expansive to maintain and common issue is oil leak on the FA and FB engine. Once it happen need ti bring down the engine and also hassle to service as well on other issues. I am interested into Subaru Levorg 2.0 with Turbo but would prefer a car with less hassle to maintain. Levorg is come with FB engine if not mistaken
Need to advise on this, thank you in advance.
I have a problem with the Subaru Forester 2015, I replaced parts inside the engine Ringe piston, connecting rod bearings, crankshaft bearings and gasket full. after repair and installation, when the engine is started, vibration occurs when the car is parked or when the speed is reduced at 10 km/h. What is the reason?
How and when should I notice it is time to change the chain timing belt? My Outback is a 2015 and has 97,556 miles
Es recomendable cambiar todo o solo el tensor si esta malo mi mi forester suena en la mañana y después se calla
