Speedkar99: "it is just a Subaru. Who cares" and MrSubaru immediately goes into an apoplectic fit, starts stuttering, spitting and foaming at the mouth :)
I remember back when you had just 19K subs or so. I really wished you had more subscribers and views because your content was so thorough and fun. Now here you are with almost half a million subscribers, soon to be a million. You, Chrisfix and Scotty Kilmer were the inspiration for me to create my own mechanics channel. I even learned the usefulness and environmental benefits of using your family's undergarment and personal hygiene items to perform repairs and cleaning. Greetings from the Dominican Republic.
I JUST found this channel a few minutes ago, killing time, not looking for my car's engine, but here it is. My dipstick is useless, valve cover is leaking oil, but of course I think she's the best car ever.
Thanks for another great teardown and analysis - I drive a 2017 Legacy with the FB25, so I was even more excited than usual when I saw this video dropped! Mine doesn't appear to be burning oil yet as of 70,000 miles, and they seem to have fixed the dipstick issue sometime after 2010 because mine is actually functional (yes, I do check my oil, despite my choice of car)
I've got a 17 Forester 2.5 with the manual, my dipstick is functional. My valve cover leaks a little. I've suspected a bit of oil burning just because it uses 1qt of oil every 2500 miles and I'm not leaving oil spots anywhere. I've had the EJ25 and burned 1qt every 300 miles, so I'm ok with this for now.
All the Subaru techs pull the engine and do it on a stand. At the dealership I worked at. They used a sheet of sandpaper on a steel plate to resurface the heads.
Old school mechanic here. Enjoy your videos and the awesome fun comments. Also the back ground aircraft turbine sounds. Oh has your neighbour finished his renovations? Cheers from New Zealand.
@ thank you for your reply. Just keep those videos coming. Any chance of an old school engine strip down. Maybe an old 6 cylinder thumper just to confuse the younger set and to prove how skilled we were in getting dirty ,how we could repair every thing from front to rear. Use words like bearing blue, white metal bearing scraping, back lash, ignition dwell, points or contact adjustment, twin side draught carb balancing etc, engine knock, generator voltage and current adjustment. King pin bush reaming. Etc etc. Have a great day
All your dry humor call-outs on poor engineering/ cost saving measures make you a fun watch! Also, a long time ago you mentioned you got your bachelor's/ graduate degrees in was it mechanical or electrical engineering or was it both? You know all this information so well, I'm glad you are sharing it the way you do! Thank you!
Sooooo over complicated. I once owned 5 VW Beetles with flat-4 boxer engines. Air cooled, they all ran hot (350-500 F ) . Not one of them ever had any of these self- destruct problems. Love your humor and these tear down episodes. Stay well.
I do oil changes on these all day. You don’t make a mess with top mounted filters (gravity kind of does a thing). Just because the pan had oil doesn’t mean it wasn’t low. Good Lord
Yea RTV on engines is a pain instead having dedicated built gaskets. Just replaced a cylinder head on a skyactiv turbo mazda and the front timing cover uses RTV so i had to scrape all the old stuff off and reseal it
I have a 2024 Crosstrek Wilderness. New FB25 with direct injection. I'm very diligent with maintenance on all my vehicles. Curious to see if I actually have a problem. I hope not. I quite like Subarus. The CVT is definitely one of the better ones I've driven and the AWD system is excellent. Always enjoy these teardowns. Thanks
Oil changes every 8-10,000km and CVT fluid change every 100,000km. Don't forget to replace the PCV valve every 60,000km too. Differential oil (front and back) should be replaced every 50,000km.
Cool video. +1 possible unpredictable fail that can happen to my 2014 Forester. Not only you can put your staff on top of engine, but also all accessories - ac/alternator/belt is easily accessible. Spark plug problem overblown - you just need a low profile ratchet + good set of swivel extensions to do it (except BRZ/FRS/GR86, you need to drop or slightly lift engine for it =) ). Complicated engine compared to I4, but not complex overall to modern tech.
The open deck with the kerf cut, oh boy. Why can't they just leave the kerf cut out, then add a small port beneath the sealing surface? This seems like such a recipe for head gasket failure.
The F series engines are unheard of for having HG failures, the EJs did have their plethora of issues if wasn't babied, they just couldn't tolerate neglect and abuse, HG failures were uncommon in the EJ257, slightly more in EJ255 and almost all the time in the EJ253/251s.
EGR in the 70's on our hot rods (yeah old fart) used to get rerouted into a small coffee can with a roll of toilet paper to absorb the oily fumes, Of course we changes the fossil fuel oil every 3k miles. Ah the old old days. Great tear down bro. Don't know if you've ever dissected a rotary engine. Need to look at your library. I find them like an air head BMW motorcycle, "simple by choice". Seems not much snow on the other side of the pond. 😎 South side NE a drag.
engineers designed the spring endurance to factor n. accountants modified it n-1 to save costs. marketing reduce it to n - 2 to shorten product life cycle. consumer experiences spring failure trades it in for a ev.
For a while subaru engines were known as, a gasket weighting the blow. I remember people who owned the early models and all of them had oil leaks or gaskets that blew. Consumption was another big problem. In some models it still is. My neighbor's son subaru forgot which model, its gasket blue and cracked the engine, under 30,000 miles.
Don't do manufacturers recommendations. They often stretch it too much. Half that. And hey, my backyard isn't a bad place to be 🤣. At least it'll be featured here than in a scrap incinerator somewhere.
I have a 2011 forester which had a recall for short block replacement. I do notice some kind ticking sound from the engine after the repair. Subaru spring recall only for 2L . Mine is FB25 like the one in the video. It can be catastrophic.What should I do?
Get the compression checked to see if a valve is stuck or floating. You can go in there with a borescope to see if there's any damage. Any check engine light for a misfire?
@@speedkar99actually, their cvts are not so bad and I like them more than some automatic transmission (e.g. 6f35). I think there is more chance that engine can give you trouble, but only after 130k miles or so
If you buy it new, maintain it religiously, don’t push it hard iand change oil every 5 k miles, it will last and give you a ton of emotions with very good fuel economy. I have a 2016 Forester with fb25 - had a great experience with this car. But I think it is better to sell it once it hits 130k miles or so.
Good job! Any help you guide me how to get red of code P0657 in 2022 honda accord? Car runs fine no issue. Also, problem with Auto start/stop light blinking in dash info near speedmeter is blinking
Subaru’s require diligent maintenance. If you maintain them and don’t abuse them when driving, they will last. Many cars today won’t last even if you maintain them.
@@speedkar99 Not always fatal though. I had one go on the 4.6L 32V and it was a quick fix, but YMMV, especially if you wait. But there are cases where the keepers pop right out and you are $crewed.
Yeah my VW Jetta throttle stuck open driving through the Canadian Rockies, middle of winter. You think you can jar it unstuck by punching the accelerator, nope just opens it further. A bit harrowing. Hazards, Turn off engine, WD 40 throttle body, wire. Proceed
Change oil every 5k miles, do all maintenance religiously, change cvt fluid often especially if going off-road. Try not to rev it higher than 2-3k rpm for long periods (do not overheat the engine). Sell it once you hit 130k miles or so.
Die hard Subaru owners are 'still' telling me about the greatness of the engine package and the low center of gravity! my God, they never stop. You always get the race car pedigree crap from them ... I know a neighbor who has gone through 3 engines on two different Subaru and still swears by them. Like a cult/ or the Liberal party.
They will once hybrids become mainstream. Like other small companies they will continue to refine the combustion engine until it is outlawed altogether.
Its not only low center of gravity, but also low engine, which makes front of car much lower and massively improves visibility. In other cars you cannot see anything in front of car without camera, in Subaru you can.
I think this engine design adds to the vehicle’s off-road capabilities. My Forester 2.5l is indeed a bit sluggish on the road but a real beast in the mud. I also agree on greater visibility
I took this as the engine looks sideways flat instead of the traditional upright inline 4. People so quick to be judgemental instead of trying to understand what is actually meant.
EVERYTIME I SEE PEOPLE WHO REPORT OIL BURNING ON THESE FA/FB'S THEY ARE ALL RUNNING 0W20..JAPANESE OWNERS MANUALS AND CARS COME WITH 5W30 AND SAY ITS OK. 0W20 WAS AN EPA PREREQUISITE. I KNOW OIL IS A SUPER POLARIZED TOPIC BUT IVE SEEN SEVERAL PEOPLE STOP THE OIL BURNING BY RUNNING 5W30 AND ON TURBO ENGINES ADDING A AOS HELPS ALOT.
TOTALLY AGREE ABOUT THE PLASTIC GUIDES..I DONT THINK PLASTIC SHOULD BE ANYWHERE ON ANYTHING THSLAT EXPERIENCES THOUSANDS OF HEAT CYCLES..BMW AND STELLANTIS ARE THE WORST FOR THIS.
@ it must land bro🤯, I drive a Mazda, love Toyotas & Hondas pity for my lifestyle their lineups don’t have what I need. In the future might get the Civic R but I don’t like speed 🤷🏾♂️ rather fun driving 🥳
It was the reason I didnt buy one. I thought, finally, a cheap fun RWD reliable Toyota.. they havent made those since the mid-80's.. then i see the boxer subaru engine 😑
Boxer is one of the best if not the best engine layouts. There is a reason they are almost exclusively used by Porsche. sure the ej and fa engines have their shortcomings and aren't as dummy proof as an inline layout but for a car that is designed to be cheap lightweight and prioritize performance it's a pretty clear answer. 220 hp out of an na 2.4 L is no slouch. We all know the 86 chassis is one of the best handling modern affordable vehicles having to give some credit to the perfect balance and low center of gravity of the boxer engine. There are definitely other great options but I think it's the perfect choice. Don't forget that Subaru is now rated number one most reliable by consumer reports 🤷 there engines have come a long way from the bad rap the na ej25x got for head gasket failure and oil starvation in the late 2000s. Toyota's 3 cylinder from the gr which would be the other option isn't doing too hot for reliability in case you haven't seen
The head gasket issues were fixed long ago.. That was the only weak point. And maybe piston rings when modifying beyond their limits. Other than that they are solid engines when maintained correctly. There's a reason Subarus reliability has greatly improved over the decades and is now up there with Toyota/Lexus. But ignants are still stuck in the past..
@@speedkar99 Miata is the only NA and reliable RWD affordable car now. the trend with turbo, GDI, and hybrid is bad for reliability. too many ways to fail.
That's why Subaru has moved up in tier with Toyota/Lexus for most reliable manufacturers to date? Another cluless dolt that has no idea what they're talking about. The reason they fail is from lack of maintenance and/or abuse.
So glad to know longer own a Subaru, pretty much nothing but problems ever since I had it. To be fair though it was high KMs and I have no idea what the actual state of the engine was. All I know is that it ran terribly and the fuel economy sucked
@@speedkar99No it was a 2006 Impreza r ej204 engine. Don't think the us ever saw that engine specifically. Basically it was just a standard ej 20 but with a higher compression ratio and dohc and vvt. The main issue I had with it was jumpy acceleration and power loss, replaced spark plugs did nothing, cleaned body grounds did nothing, new air filter and upper engine cleaner through the system did nothing, cleaned throttle body did nothing. Figured in the end it might've been the throttle body was bad or more specifically the position sensor, did get a park/neutral switch code as well even though it was a manual(apparently these cars still have them regardless). Anyway, looked online and apparently the low power and jumpy acceleration was very commoner on the engine, people seemed to think it was an ecu issue or and knock sensor issue, because the car was pulling timing on lower quality fuels. Idk what it was and I don't care, it's gone now and I don't hate Subaru as a whole their ok, but would I own another one of their cars again, yeah probably not unless it wasn't my main car and I had alot more money.
@@jimmytimmy3680depends how their looked after honestly. Their not straight up rubbish but if their neglected and not kept up on maintenance they might as well be
@ respect on you man, not a lot of engineers are capable of breaking things like you do. I see your engineering eye when you talk about some of the choices manufacturers make. I understand a lot of those choices are ease of manufacturing not ease of repair.
Great informative teardown! Sad that one little spring ruined the entire engine 😢
Thanks, I watch your videos too!
Yeah it's quite sad alot of subies in this era died this way
Thanks for the thorough explanations of everything! This channel is the only place I get to see the inside of an engine like that. 😁

Very good presentation. I drive VW Jetta TDI and after 9 years from new I have already seen pistons from above and from below…
Yea RTV on engines is a pain instead having dedicated built gaskets. Just replaced a cylinder head on a skyactiv turbo mazda and the front timing cover uses RTV so i had to scrape all the old stuff off and reseal it

Cool video. +1 possible unpredictable fail that can happen to my 2014 Forester.
Not only you can put your staff on top of engine, but also all accessories - ac/alternator/belt is easily accessible. Spark plug problem overblown - you just need a low profile ratchet + good set of swivel extensions to do it (except BRZ/FRS/GR86, you need to drop or slightly lift engine for it =) ). Complicated engine compared to I4, but not complex overall to modern tech.
Agreed. For most maintainence items (besides spark plugs and valve cover) access is pretty easy.
The open deck with the kerf cut, oh boy. Why can't they just leave the kerf cut out, then add a small port beneath the sealing surface? This seems like such a recipe for head gasket failure.
That would make it semi closed block, which is fine, just adds weight and strength at the detriment of cooling when it's not needed.

It also clogs the intake

Change oil every 5k miles, do all maintenance religiously, change cvt fluid often especially if going off-road. Try not to rev it higher than 2-3k rpm for long periods (do not overheat the engine). Sell it once you hit 130k miles or so.
Oil oil oil.
Idk it just seems a little excessive to take on the complexity of 2 heads for a 4cyl
It's got its ups and downs ..
Center of gravity and balance are it's main advantage
Do you have an estimate how many kilometer (or miles) has this engine gone thru? If it gets to this stage at 300K, it is consider a win.
It’s a 2013, doubt it had more than 100k-150k on it.
I didn't get the mileage from previous owner
I can’t believe Subaru sticks with this engine… so complicated! Why? To have a low center of gravity?
Do you think they will ever abandon it?

I like Eric he does great work.
I wanted a subaru once, then I found they put their engines sideways.
I wanted a BRZ once, till I found out it had Subaru engine
Longitudinal is the correct way....for RWD 😎
These are not transverse engines.. 🤦🏼♂️ Learn the difference
I took this as the engine looks sideways flat instead of the traditional upright inline 4.
People so quick to be judgemental instead of trying to understand what is actually meant.
@@chonglers1513 let's call it flipped hehe
Teardown a V35A-FTS from a Toyota Tundra next.
EVERYTIME I SEE PEOPLE WHO REPORT OIL BURNING ON THESE FA/FB'S THEY ARE ALL RUNNING 0W20..JAPANESE OWNERS MANUALS AND CARS COME WITH 5W30 AND SAY ITS OK. 0W20 WAS AN EPA PREREQUISITE. I KNOW OIL IS A SUPER POLARIZED TOPIC BUT IVE SEEN SEVERAL PEOPLE STOP THE OIL BURNING BY RUNNING 5W30 AND ON TURBO ENGINES ADDING A AOS HELPS ALOT.
The main cause of engine failure is lack of maintenance.
Due to lack of oil pressure in that hydraulic lifter yes
Brittle valves cracks etc
TOTALLY AGREE ABOUT THE PLASTIC GUIDES..I DONT THINK PLASTIC SHOULD BE ANYWHERE ON ANYTHING THSLAT EXPERIENCES THOUSANDS OF HEAT CYCLES..BMW AND STELLANTIS ARE THE WORST FOR THIS.
Thats a lot of rust
We live in Canada and Subarus are not the best with their fasteners
More reliable than Toyota, Honda & Mazda🤯
Oh boy ... another one!
@ it must land bro🤯, I drive a Mazda, love Toyotas & Hondas pity for my lifestyle their lineups don’t have what I need. In the future might get the Civic R but I don’t like speed 🤷🏾♂️ rather fun driving 🥳
IF you get a manual and avoid the CVT and keep oil in it...
@ manual’s are fun
I’m changing my oil every 3-5k miles.
Good move. Forget 10+K mile intervals
2006 Subaru sti ej257 engine po302 cracked exhaust valve $ 5116 to repair
Ouch
eh! Your brother has got no more teeth left? How old is he? 🤣🤣🤣🤣🤣🤣
He does but doesn't brush. If he doesn't need it I'll make better use of it
They screwed up the length of the dipstick? Really?
lol
If it showed empty and I drained a pan full that means they're trying to cheat 🤣
With injection, that engine would have 1/3 the parts if it was just a flathead.
It's good to be different. Otherwise we'd have another boring Nissan/Toyota 4 banger video tearing down
@@speedkar99 Good thing it's not made by Audi or BMW. Would have 10 more chains in it. In the back of the engine.
Is that the stock dipstick which is to short? In that case it is insane...
It sure is stock. I think Subaru did that on purpose to give owners some leeway they didn't know they have
Toyota will no longer use boxer engines
In the 86?
@@speedkar99 2025 models
it is too bad that the Toyota GR86 is a Boxer engine. Not the Toyota reliability....
It was the reason I didnt buy one. I thought, finally, a cheap fun RWD reliable Toyota.. they havent made those since the mid-80's.. then i see the boxer subaru engine 😑
Yeah they have their issues sadly 😕
But there's always the Miata
Boxer is one of the best if not the best engine layouts. There is a reason they are almost exclusively used by Porsche. sure the ej and fa engines have their shortcomings and aren't as dummy proof as an inline layout but for a car that is designed to be cheap lightweight and prioritize performance it's a pretty clear answer. 220 hp out of an na 2.4 L is no slouch. We all know the 86 chassis is one of the best handling modern affordable vehicles having to give some credit to the perfect balance and low center of gravity of the boxer engine. There are definitely other great options but I think it's the perfect choice. Don't forget that Subaru is now rated number one most reliable by consumer reports 🤷 there engines have come a long way from the bad rap the na ej25x got for head gasket failure and oil starvation in the late 2000s. Toyota's 3 cylinder from the gr which would be the other option isn't doing too hot for reliability in case you haven't seen
The head gasket issues were fixed long ago.. That was the only weak point. And maybe piston rings when modifying beyond their limits. Other than that they are solid engines when maintained correctly. There's a reason Subarus reliability has greatly improved over the decades and is now up there with Toyota/Lexus. But ignants are still stuck in the past..
@@speedkar99 Miata is the only NA and reliable RWD affordable car now. the trend with turbo, GDI, and hybrid is bad for reliability. too many ways to fail.
I love your videos but titling them "why subaru engines fail" is such a weird overgeneralization.
Why do they fail? It's in the name: Subaru
Haha
That's why Subaru has moved up in tier with Toyota/Lexus for most reliable manufacturers to date? Another cluless dolt that has no idea what they're talking about. The reason they fail is from lack of maintenance and/or abuse.
Flat engines are just stupid
I call it an unnecessary solution for a non existent problem
They are a unique way of making the same ~170HP than a conventional inline 4 banger
So glad to know longer own a Subaru, pretty much nothing but problems ever since I had it. To be fair though it was high KMs and I have no idea what the actual state of the engine was. All I know is that it ran terribly and the fuel economy sucked
Any Subaru after 50,000 miles are 🗑
What was the main issue? Oil burning? cVT?
@@speedkar99No it was a 2006 Impreza r ej204 engine. Don't think the us ever saw that engine specifically. Basically it was just a standard ej 20 but with a higher compression ratio and dohc and vvt. The main issue I had with it was jumpy acceleration and power loss, replaced spark plugs did nothing, cleaned body grounds did nothing, new air filter and upper engine cleaner through the system did nothing, cleaned throttle body did nothing. Figured in the end it might've been the throttle body was bad or more specifically the position sensor, did get a park/neutral switch code as well even though it was a manual(apparently these cars still have them regardless).
Anyway, looked online and apparently the low power and jumpy acceleration was very commoner on the engine, people seemed to think it was an ecu issue or and knock sensor issue, because the car was pulling timing on lower quality fuels. Idk what it was and I don't care, it's gone now and I don't hate Subaru as a whole their ok, but would I own another one of their cars again, yeah probably not unless it wasn't my main car and I had alot more money.
@@jimmytimmy3680depends how their looked after honestly. Their not straight up rubbish but if their neglected and not kept up on maintenance they might as well be
Who in their right mind wanna buy a Subaru??
They are in stock and selling at the sticker price. That's more than you can say for many makes. It was simple leasing my 25 Forester.
🌈
Wow that thing is crusty. Car mustve lived in the sea 😂 is this how cars look in America?
Canada where we use salt on the road to accelerate rust to see if the engine or the body causes the car to be junked first
Love the jokes 😂 New engines... not so much.
Glad you appreciate it
Questionable Engine Life Terrible Fuel Economy No Power, Subaru been perfecting that Recipe for Decades.
People buy them for utility and perceived AWD capability.
Would disagree about fuel economy and power. But engines yeah - too capricious
Subaroo smackeroo ! 🤣
So many scams early commenter
Ok
I was going to ask if you were an engineer.
Yeah I'm a mechanical engineer.
I just love breaking things and working hands on as a hobby.
@ respect on you man, not a lot of engineers are capable of breaking things like you do. I see your engineering eye when you talk about some of the choices manufacturers make. I understand a lot of those choices are ease of manufacturing not ease of repair.
