Engine sauce from the water pan. Man, the one liners just keep getting better. And the water pump throw was hilarious, loved it. Your videos are entertaining and informative at the same time. I know so much more about modern IC engine design than I ever could on my own. You are this clearing house where you get access to all the designs, good and bad.
Ah ha ha ha! I laughed hard at that one and nearly shot my soda through my nose. And beforr anyone gets butthurt... I owned one of those in the past, and I still own another newer hemi without that problem. So have a sense of humor! Lol
As a Subaru guy... That was the best Water Pump throw I've ever seen! Also note: These turbo Subarus have gotten so cheap that kids with no money buy them then blow an engine then throw in a "cheap" JDM engine and blow it again and wind up in so much dept its just hilarity.
There was a dude in Weapons 1/2 with me, that went through 2 of these engines in 4 years…put that on top of a car payment that 650ish bucks a month. I told him not to do it because the reviews were so bad, but he only cared about aesthetics. Dude was broke 6 days after payday.
@@Pukefroth666 I'll trust an EJ20 way more than a junky 2.5 no matter what it came out of. There's way less blown Impreza WRX's & STI's where i live exactly because they came with an EJ20 instead of EJ25 😂🤣😂
A 6.9 idi or a 7.3 idi would be awesome to see torn down. The ignition cups would be cool to see. Keystone rings and cavitation on the 7.3 are always interesting. Keep up the good work!
It’s not the boost. It’s the lack of sympathy from the driver. Running a boxer hard from cold, low on oil, coolant leak, failing to idle the engine when it’s heat soaked … not checking the oil weekly or every tank of petrol … these all contribute to a bad reputation. There are many ways to kill these engines and most of them are unique to boxer. For example over filling the oil will blow by the spark plug tubes and drown them FROM THE OUTSIDE
@@theairstig9164hold up, how overfilled are we talking about???I put 5 quarts in my WRX even though it calls for 4.4 (which I find very underwhelming for a 2.5 displacement). Mind you, it has no leaks (yet), the PCV system is working (for now) and at the last spark plug change, the plugs looked fine.
Realized why I like your channel: other channels show what works, and you show distructive testing which is probably more important because it is what doesn't work
For once I agreed with all the places Blue got used. I'd like to be a fly and sit in on the meetings where engineers try to decide how to put these puzzles together! Or if they say: "we have room here. Let's hide a water manifold or something here" - 😂
Rem years ago chatting to a CASE(tractor) design engineer about how they put things where they did on the tractors and the "ease" of carrying out repairs,he replied "we mostly design them for ease of assembly" god but i could have just hit him repeatedly.
Wow starting off the new year with an impossible find... a broken Subaru boxer. That must have been like finding the one needle in a zillion hay stacks.
@@imabebebebe2496 The Impreza doesn't come with the 6-speed like the Crosstrek does. Also the 5MT is mechanical linkage. Some complain about the 6 speed feeling sloppy because of the cable linkage.
Thank you Eric for starting the new year off on the right foot. I have now deemed you the Prospector of forbidden stripper glitter, when you dropped that oil pan it looked like you were panning for gold, thanks again and keep up the great content.
The manifold setup means that EJ2OX was installed in a car that came with an EJ255, an 05-06 LGT based on the injectors. In that car, with the JDM VVT gears and cams still in place, the exhaust cam advance angle will float around at random. In addition to the lack of tuning for high compression causing detonation as you mentioned.
So essentially what you're saying is that this setup was destined for failure from the beginning because it was "a jungle of things done badly." Thank you for the additional details. :)
Eric, I wonder if you could ever get lucky enough to get a blown up aviation engine in for a tear down, they also go big or go home when they let go. Always enjoy your tear downs and other projects! Thanks for all you do!
Always wondered if airplane engines actually do get bad enough to blow up with their strict logged maintenance. Not to mention what could happen to the entire craft if that did occur
You are a nice kid, and I like you. After 25 years being a cop and having everyone lie to me, fight me and complain a lot, I find your channel very refreshing. I’m 76 years old and until I became disabled, I did all of my auto machanics. All of my experience has been under a shade tree, but I have rebuilt and replaced many engines, but watching you makes me so very serene. Thank you for that!
Some Japanese teenager got hold of this car and ran the engine to 9000 RPM.... Subarus are UTILITY cars. They are designed to go through snow, not off road. And while they produce turbo cars that are seriously fun to drive (!), their horizontally opposed design with aluminum construction means that that CANNOT handle the kind of boost that a 2JZ or a K24, or for that matter an EA888 can handle. The very best Subaru's have 6 cylinder engines. Specifically, the EZ30/EZ36 cars. DOHC 24 valves, four cams, chain driven cams, they had NO issues with head gaskets and run forever! I have an '01 with 114k miles, and it just runs and runs and runs. 220 hp versus the slug 165 hp EJ25 engine-
I would also like to point out, that even if you have the correct ECU and retain the twin scroll turbo and you are in NA, these engines STILL need a tune, as Eric mentioned.. just the octane difference. I have a JDM EJ20Y car in Canada, and when initially logging the car you would see the ignition timing pulling like crazy, and the power level to be lackluster as a result. once I got on the rollers, I saw impressive increase of the under the graph area, and massive improvements in drivability. if your not going the cheap route, this engine is not the one you want to put in your 2.0 WRX or 2.5GT unless you have a plan to deal with the AVCS system, whether it be both intake and exhaust in the bug eyes or exhaust only in the LGT. in legacies you can easily use the TGV harness parts and pin them to a JDM ecu's exhaust avcs control, but those ECU's have immobilizers so you also need to deal with that to run one.
So you have a EJ20Y ? , I also have a EJ20X/Y engine swapped in my wrx (not by me tho). I’m pretty sure the headgasket is going bad. Is there a chance that the EJ20Y headgaskets are different from the EJ20X ? Or are they the same , if you can reply and tell me that would be amazing , I’m having it get fixed soon and need to buy the correct gasket and seal kit. Any advice ?
@@eimmiekhim9023 they might have different cams. The block and head castings are the same, so the gasket that goes between them should be the same…. Actually any ej20 turbo head gaskets should be the same. They all mate to the same block surface.
@@funkthew0rld @20:47 is him taking off the headgasket , it has the “A” top . I should get that one right ? Because that’s what they are trying to ask on the email to help me out.
@@eimmiekhim9023 if you’re in the US or Canada, just go on rock auto, search up a 2002 Impreza turbo and buy those ones. A EJ20 is an ej20. It doesn’t matter if it’s a 205/207/20x/20y/206/201/204. The top of the block is the same shape. It’s an ej. Simple as that.
For future reference, the upper intake and TGVs come off as one piece. It makes it so you don’t have to mess with trying to mess with the fuel lines and the harness; it all comes off as one assembly. For the camshaft sprocket bolts, I always just drill them out, since “breathing on them” isn’t an option for an engine that you actually expect to run and work afterwards. Once you drill with a large enough bit, it releases all the tension on the head of the bolt and they unscrew by finger. It’s way easier than fighting with a breaker bar or impact and stripping out the bolt head, breaking the composite gears, etc. The fact that this has a cork oil pan gasket on it means that the person who installed this engine has never worked on a Subaru before (or any other Japanese engine). I’m surprised they didn’t shellac the head gaskets.
I’d hope you can find an EZ30/EZ36 at some point. Failures for the 4 cylinder boxers are common, but the Subaru flat sixes are usually better regarded and mostly reliable…save for some that like drinking their 5w30
Any teardown he does I'll watch, but the flat motors are particularly interesting to me, whatever make or cylinder count! That's a roundabout way of saying I'd love to see an EZ teardown too 😄
Subaru has let me down with only 130k miles and dealership oil changes and the engine is burning alot of oil. Not t9 mention dealership keeps damaging the paint job on my car. I'm done with subaru and that is sad since it is a great car except for the engine problems, cvt, and dealership mechanics.
OK, so hear me out! We need to make an engine entirely made from wrist pin material! It would be indestructible! Happy New Year, Eric! If I ever make it to the USA, I will stop by your yard/shop, say hi, and buy some... art! Have a great day, Sir! o7
without a failure point the whole engine will leap out of the car when something goes wrong. how you going to explain to nasa where the new crater on the moon came from?
Thanks for doing another Subaru engine. Whenever you do Subarus you always say that these cars are not for YOU. Could you say what you find most unappealing about them. It would help your viewers get a feel for you and learn your preference. It is not just the engines we wacth your channel, its your personality also. Thanks🙂
That's a 2008+ , you can tell by the dual avcs and plastic manifold. You made 1 mistake removing the intake by splitting the manifold from the tgv housings. The come together, then separated after assembly removal
Na, you're on the right track but you've mixed the original donor car and the car it was in when it died. The EJ20X/Y was only ever fitted to the JDM legacy, and they were all dual avcs, so it could be any gen 4 twinscroll leggy from 2004 onwards (some very early ones in 2003) Other parts have been fitted to it in an attempt to make it work in a USDM legacy, but it's been half-assed.
You set all the plugs together, and my childhood suddenly came back to me. Good old Sesame Street...one of these things is not like the others. One of these things, doesn't belong. Can you tell which thing is not like the others, by the time I finish this song?
Fun Fact: Subaru once built a Flat 12 engine for F1 racing. The design was 20 years out of date, was 200 horsepower down on literally every other engine on the grid and 300+ pounds overweight. It does hold an F1 record for the largest time deficit too the leader in a single qualifying lap. It set a lap time of just a hair under 8 minutes in qualifying for the 1990 san marino grand prix.
Contrary to popular internet meme belief, the EJ20 is actually a rather reliable engine. Also very capable for its time. Plus it sounds amazing. I guarantee, whatever your opinion of Subaru, if you ever get to drive a first generation Impreza with one of these in it, you'll get why people love them. Very easy to work on as well, no matter what people on the internet who have never touched them tell you.
I like that the first time I swapped an engine in one of these (because SHE let the oil get low) it only took me one day. I bought the first Subaru because SHE liked them, and then another, but have gained a lot of respect for them. They're not my style, (although I'm driving one now because life happened and I had it) but they're pretty well made and not super difficult to service, unless it's turbo, which shoves a lot of extra stuff under the hood, but even then, they're not absurd.
I’m speaking as a previous owner & someone that has actually rebuilt a couple EJ25s… I’d never own one of these cars again lol. The cars are definitely well made with really nice interiors compared to a lot of cars. The engines however are just garbage. Way too many weaknesses.
@@stevemccauley5734 The EJ20 and EJ25 are different animals in terms of reliability and performance. I personally don't own any EJ25 cars, though my family has had plenty. I do however own numerous EJ18, EJ22, and EJ20 cars with anywhere from 110,000 to over 340,000 miles all on original engines. My aunt also daily drives an Outback with an EJ25 that's nearing 300K I believe, but it has had the head gaskets done. If it wasn't for the damned EJ25 head gasket issues, Subaru wouldn't have nearly so bad a reputation nor as many memes about them. Even the EJ255 turbo engine is more reliable than the NA EJ25. Not that any of them are perfect. The EJ18 and EJ22 were absolutely bulletproof, if slow. The EJ20 isn't quite as reliable as those maybe, but just about, and with so much more performance. Plus I just love working on Subaru more than any other brand. At least the FA/FB engines don't have head gasket issues and are generally very reliable overall. The EZ 6 cylinder engines were incredibly reliable as well.
@@stevemccauley5734 Main weaknesses on EJ-series mostly affect the 2.5's. The 2.0's are actually somewhat more reliable when built because they actually have cylinder wall thickness
There weren't that many metal bits in the filter because it was clogged and bypassing most of the oil. In fact, that cheap jobber filter would have been bypassing oil even when it was new, since it wouldn't have the Subaru-spec 23 psi bypass, and is probably restrictive as well. This is the case with most aftermarket oil filters available for Subarus. OEM and PurolatorOne are both good options for these engines. A good filter can make the difference between having to do a bearing job and having to scrap the entire engine (well, maybe not in this case).
It would be an honor to have my Impreza engine featured on Eric's video, if it ever breaks. It needs to break first and it ain't broken. Not a problem at all with my engine.
The EJ20X/Y's a perfectly good motor, you can't really tune it much, it has no headroom but it's really well engineered for the stock job. Dual avcs, big oil pump (what people think of as the high flow sti oil pump was developed for the Legacy), quite high comp, and various twinscroll turbos handpicked to match the engine, mine has 245 at the wheels and absolutely gorgeous drivability and midrange for a 20 year old 2 litre turbo. They're not super durable, but they're not terrible. But, it's become a weirdly popular choice for swapping into subarus, because it's about the cheapest turbo ej you can buy, but that doesn't make it a good idea. This engine going by the other parts it has fitted has been fitted into a USDM legacy, which originally had a 2.5 litre single AVCS in it. You only do that because it's the cheapest option, so they've almost certainly bodged it in without doing much else- if you start spending the money to do it right, it stops making any sense to start out with that motor. And the EJ20X/Y is a dual avcs motor, so if you fit it without addressing that into a single avcs car like the USDM Leggy, then what you get is variable valve timing. You also end up with more compression than the stock motor, and a turbo and tune designed for that. So they almost never work properly and then they fail and people go "bloody Subaru!" It's a real shame because the only people who ever do it are people who can't afford to do the job properly, and that also means they can't afford to have their bodged in engine fail. It's almost always just the last in a long run of bad choices or bad events, because obviously if you're not reasonably comfortable money wise buying a turbo subaru was a terrible idea in the first place. TLDR don't put an EJ20X into your 2.5 litre subaru. Don't put it into your older 2 litre subaru. Don't try and tune it beyond about 300hp on the stock internals. But don't blame it for not being the right part for you. DO get a JDM twinscroll gen 4 legacy wagon, if you can, because they're ace.
The one Subaru I ever had (and bought new) needed $6000 worth of work at only 145,000 miles. So much for Subaru “reliability”…never again. FYI it was an ‘07 Impreza no turbo.
Its insane to me I’ve never had any issues with ej motors, all mine are usdm, and im not saying they are perfect, one leaks oil really bad, yet my brand new ford 3.5 eco boost f150 blew up, i have 2 19 year old ejs one with 205,000 miles the other with 225,000 miles the f150 had 11,000 miles, i am a subaru guy so maybe because i check my oil so often? I also have a fb20D subaru impreza
I have a friend who had worse cam caps, cams, and journals than those that he cleaned with sandpaper when he did his "rebuild" and that little dodge neon engine is still running 6yrs later no problems. I dont reuse cams, journals or caps that bad. I bore them out, install oversized cams that some companies sell for this type of work, then finish my rebuild. Those engines never have issues when i do that. But ive been waiting for his engine to die so i can rebuild it correctly for him 😂but it hasnt happened.
How do you do that? It would be a "blind" line boring operation, with the caps installed on the head. Most "block" line boring equipment is not made to do a blind hole, and is for much larger crankshaft main bearings. Who makes cams with slightly larger bearing journals? I have only seen large bearing cams for v8s, where stock bearing diameters can limit lobe lift. This unique problem does not apply to engines with removable cam bearing caps. What you suggest is not impossible, but is a VERY strange, unlikely solution to a problem better solved by cheap brand new parts.
As someone who's put 400,000+ miles on 3 different subaru EJ engines that I DID NOT BLOW UP, I can assure you they're fine motors and that the problem is user error always going WOT in high gear on huge amounts of boost. bye bye rod bearing.
So that's part of the problem, the owner of this USDM 2.5 litre car has treated the engine as a disposable item, so they bought the cheapest replacement EJ they could find, a JDM 2 litre with very different spec, and they've fitted it badly. And then it's blown up and they've gone "bloody subarus!" instead of "ah that's my fault, I did that". In their original home, with japanese fuel (or a proper remap for US low octane) they're great- reliable, not too stressed. You don't tune em, they have very little headroom. But as an engine crammed in a hurry into a US car? Just a bad idea. But you only do it because they're dirt cheap, and so you fit it badly because that's all you can afford to do. If you could afford to fit it properly and retune and deal with teh dual avcs etc, you'd not start out with the EJ20X/Y in the first place. So it's chicken and egg but almost every time one of these motors gets put in a US car it's a bad idea.
When you're tearing down a 500 hp v10 and It's destroyed a piston, that's one thing. After all, you still have 9 cylinders and 450(?) horsepower driving what's left of the engine. Inspection ports and piston gravel can be expected. When you're tearing down a flat four with 200-400(?) horsepower, you only have 3 cylinders and 150-300(?) horsepower driving what's left of the engine, piston gravel is kind of a surprise. But then the keyword here is 'turbo'.
I put a JDM into my Forester. I had to swap out a few pieces. It wouldn't start until I swapped the left cam gear. Runs great since, and no more head gasket leak.
@@eimmiekhim9023 It was an EJ25. I don't know which series. It came with an electronic throttle body. I had to use the old one. Basically, It was a long block with some extra parts I couldn't use. I found it on Ebay for about $2500
That block off plate on at 17:20 ish looks like it is for an ej206/208 second turbo line, I am not sure as I have not been hands on, but I know many people convert the twin turbo ejs to single for simplicity and reliability (the PCV system is a nightmare, and the exhaust headers are overly complex)
Unpopular opinion, these are amazing engines that got cheap enough for people that were never going to maintain them to get their hands on. 100% of failures on these ive ever seen have been poor maintainance related.
Subaru owners are very vocal about how great and trouble free Subarus are. But when they blow their engines and the CVT dies, they go off the grid... These are some of the worse cars made in decades.
Speaking of smashed spark plugs, (not really smashed, but more like broken) my dad was trying to start a Stihl concrete saw one time, it wouldn't start because it didn't have any compression. He pulled the spark plug out, and the ceramic part of the plug had completely separated from the nut of the plug! I still have that spark plug to this day. It baffles me every time I look at it.
I agree - there are so many big and little ways that the boxer layout makes assembly harder. The items I had never thought about were the gudgeon/wrist pin access ports. Not a solution used in the VW engine. But it has separate cylinders.
Exactly fascinating trash. Screw sub for using this boxer trash. I think i hate this engine more than mazda rotary trash.😂. Sube is trash and waste of good awd id say theyre multi generational sobs. Right up there w trash dodge.
Subaru should just abandon the flat engine. I dare say the Solterra will be more reliable than anything else in their lineup this year simply because it doesn't have one.
Well that explains why the end of that spark plug was dished. The wrist pin slammed into it. By the looks of that bad head that engine was turning pretty fast when it decided to take an early retirement.
Many years ago, I knew a person who replaced his Japanese car engine with one imported from Japan. He told me that due to inspection rules in Japan and other factors, cars are not kept long in Japan. This is the reason that low milage imported Japanese engines are available.
That is true. Also, people in Japan hardly need cars to travel in the city. Traveling outside the city, they may use a car, but even then, their travel distance will not be large due to living on islands and can only go so far.
Exactly right. This motor is out of a gen 4 Legacy, a ton of those get exported to the UK complete as we're also right hand drive, but there's so many that it only makes sense to export really nice condition cars. If it's got any amount of damage or wear or rust, then it makes more sense to scrap, and then a lot of the engines end up in the US for dirt cheap, and fitted inappropriately into the wrong cars, like this one. It's a sad end for those almost-good-enough cars!
You should try to do an fb20 out of a 2013-2017 Impreza or 2103-2018 crosstrek. Those engines had a recall on valve springs. Maybe you could find one with broken springs.
Eric, what brand disposable gloves do you use? My wife and I are pretty impressed with them! Also, you chose an engine from the perfect brand to deliver destruction!
It's not that Subaru boxers are prone to fail. Great points about just buy cheap to go fast... lol It's also that tubers try to make them 600 HP drag machines and everyone either modifies them beyond intended spec, or don't treat and maintain them well. Pretty spectacular that NY 'pop' must have been.
Yup, in this case they've shoehorned a 2 litre dual avcs engine into a us spec 2.5 litre car, badly, and so it'll have never worked properly. There's no way the owner will have tuned it for us pump fuel or addressed the turbo and compression changes (I say that for sure, because absolutely nobody would fit the dual avcs and leave the exhaust avcs in place but disconnected as they have here, but do a proper tune). It's a bodge from top to bottom and no wonder it ends badly.
Subaru owner here who's been through it all: Wouldn't mind having some of those parts to add to my Subaru museum of destruction in my garage, which currently includes such popular displays as the grenaded viscous coupling center diff, transmission gears stripped of most of their teeth, and roller bearings that spit out pieces of circlip when you spin them. As for the reason this engine let go, I'd guess low oil. It doesn't take much wear before they burn a quart of oil every 150 miles, at which point it's only a matter of time before you forget to check one day, and then bam. I was told the reason we see so many JDM engines in the US is that for cultural reasons, the Japanese people who own cars will only buy new ones, and only keep them for 5 years. So any JDM cars over 5 years old are simply sent to scrappers, who part them out and send the stuff everywhere but Japan.
I've heard of oil consumption issues with Subaru's, but haven't experienced it myself. My '99 Legacy doesn't burn any oil. I bought it new and have done every oil change except the first with Mobil 1. In 2018 when a head gasket failed (imagine that), I pulled the engine as it was close to 200k mi. and figured I'd tear it down for a look. Heads were great. Machine shop surprised how good they looked. New stem seals. Crank was polished and bores honed. Another 5 years of driving. No oil consumption and the head gaskets are holding 😅.
@@timsilva1944 My goodness. You took good care of the engine, took it to the machine shop to clean everything up for the head gasket job and your engine is like brand new again. That's the way.
@@timsilva1944Good to hear the '99 held up pretty well. My 2010, which I maintain religiously myself since I'm a former mechanic, was using 1qt every 200 miles at 140k miles. The rings were shot with extreme cylinder scoring. It had been drinking oil since 50k miles, was never run low, and I always run top of the line synthetic and oem filter. We kept driving it that way until the head gaskets decided oil and antifreeze should mix. On the plus side, the rebuilt engine we have in it now runs perfect and doesn't use a drop of oil.
@@nowiecoche Thanks. Head gasket blew right after I replaced all 4 struts, lower control arm bushings, CV axles and front hub bearings. 😡 I wasn't too keen on replacing head gaskets with the engine in the car, so I figured why not freshen it up. It's a manual, so a new clutch was a given at that stage.
This has been interesting to me, and I appreciate the information you've given, because I was one who'd always thought of Subaru as a completely bulletproof engine maker. I guess we all can respond to marketing stupidly. I still have high regard for the carmaker (I've been a big fan of the boxer design, having owned two Corvairs), but you've given me much to consider about Subaru.
Bullet proof or not, you still need to service the engine.. oil change, belt, spark plug change, pumps, gaskets etc. that's where it gets tricky with the boxer engines because of the way it sits, it can get labour intensive. By the time second and third owners they just "let it ride".
Thanks to both of you for those valuable comments. I had originally not realized that he was working with a reworked engine here, and that the topic was about second hand examples. But I've gathered that there are certain weaknesses in Subaru engines from the beginning, if you're not following every model and don't do your homework.
We need some big displacement destruction, they never seem to disappoint in the carnage department that's for sure lol P.S. Still patiently waiting for something to displace 8.0L Magnum V10 from its crown because it had *EVERYTHING*
If that was you guys who provided this gem, THANK YOU!!! Would love to hear the backstory on that core. Also, have enjoyed chatting with you guys on the phone in the past re: a non-Subie motor I was trying to find. Cheers!
I had no idea they make a high compression engine that is Split Block. I dare say, What a Stupid Idea 🤡 Enjoyed the mess and over-engineered tear down 💪
If you never tested the pistons I would have never known that the engine was bad. Thank you for being so thorough 👌

It’s not the boost. It’s the lack of sympathy from the driver. Running a boxer hard from cold, low on oil, coolant leak, failing to idle the engine when it’s heat soaked … not checking the oil weekly or every tank of petrol … these all contribute to a bad reputation.
There are many ways to kill these engines and most of them are unique to boxer. For example over filling the oil will blow by the spark plug tubes and drown them FROM THE OUTSIDE
@@theairstig9164hold up, how overfilled are we talking about???I put 5 quarts in my WRX even though it calls for 4.4 (which I find very underwhelming for a 2.5 displacement). Mind you, it has no leaks (yet), the PCV system is working (for now) and at the last spark plug change, the plugs looked fine.
Realized why I like your channel: other channels show what works, and you show distructive testing which is probably more important because it is what doesn't work
For once I agreed with all the places Blue got used.
I'd like to be a fly and sit in on the meetings where engineers try to decide how to put these puzzles together! Or if they say: "we have room here. Let's hide a water manifold or something here" - 😂

If you were a fly, you wouldn't have the intelligence to understand it, so why bother?

@@imabebebebe2496 The Impreza doesn't come with the 6-speed like the Crosstrek does. Also the 5MT is mechanical linkage. Some complain about the 6 speed feeling sloppy because of the cable linkage.
Impossible? Have you seen the types of people who buy Subarus with turbos?
I have a feeling that the oil filter has been bypassing for a long time.
Thank you Eric for starting the new year off on the right foot. I have now deemed you the Prospector of forbidden stripper glitter, when you dropped that oil pan it looked like you were panning for gold, thanks again and keep up the great content.
Panning for gold priceless absolutely priceless.
The manifold setup means that EJ2OX was installed in a car that came with an EJ255, an 05-06 LGT based on the injectors. In that car, with the JDM VVT gears and cams still in place, the exhaust cam advance angle will float around at random. In addition to the lack of tuning for high compression causing detonation as you mentioned.
So essentially what you're saying is that this setup was destined for failure from the beginning because it was "a jungle of things done badly." Thank you for the additional details. :)

Eric, I wonder if you could ever get lucky enough to get a blown up aviation engine in for a tear down, they also go big or go home when they let go. Always enjoy your tear downs and other projects! Thanks for all you do!
Always wondered if airplane engines actually do get bad enough to blow up with their strict logged maintenance. Not to mention what could happen to the entire craft if that did occur
i so wish Lycoming didn't want the one that we had that let a cylinder go mid-flight back. id have loved to seen it torn down
@@Onewheelordeal oh yes they do. turbines not so much, but pistons definitely do
A blown up PT6 turbo-prop engine maybe?
@yeahitskimmel I've seen some of the videos of them failing. they've failed so violently that the engine cowling was shredded from the flying debris
Happy New Year Eric. Wounds. On the block. Let the carnage unfold. A cork gasket and a party basket 😂🤣.
I love my 2013 Subaru Legacy and its FB25 engine, but videos like this encourage me to keep up on the maintenance.
Hey, FB gang here! Sadly, no fanfare for us.
Got an FB20, Impreza. No issues or hiccups.
2015 Levorg here, and I just got an oil change. Topped up the coolant myself since you can buy the Subaru stuff online.
The F-series engines are much more reliable than the E-series thankfully (though you should definitely still keep up with the oil changes)
It's going to blow up trust me. Get rid of asap.
The FA/FB engines had some early teething issues, but overall are much more reliable than EJs
Science: water and oil dont mix
Subaru: hold my head gasket and rod bearings, watch this
You are a nice kid, and I like you. After 25 years being a cop and having everyone lie to me, fight me and complain a lot, I find your channel very refreshing. I’m 76 years old and until I became disabled, I did all of my auto machanics. All of my experience has been under a shade tree, but I have rebuilt and replaced many engines, but watching you makes me so very serene. Thank you for that!
I love the teardowns either way! Carnage or not it never fails to entertain!
You've had it too easy lately, these recent teardowns none of the dip sticks have fought you. Can't wait for the next one.
Some Japanese teenager got hold of this car and ran the engine to 9000 RPM....
Subarus are UTILITY cars. They are designed to go through snow, not off road. And while they produce turbo cars that are seriously fun to drive (!), their horizontally opposed design with aluminum construction means that that CANNOT handle the kind of boost that a 2JZ or a K24, or for that matter an EA888 can handle.
The very best Subaru's have 6 cylinder engines. Specifically, the EZ30/EZ36 cars. DOHC 24 valves, four cams, chain driven cams, they had NO issues with head gaskets and run forever! I have an '01 with 114k miles, and it just runs and runs and runs. 220 hp versus the slug 165 hp EJ25 engine-
How dare you not mention the EG33. You lost all credibility
@@OggaDugga Turkey. Timing belts-
@@Flies2FLL part of scheduled maintenance, every engine from that era was belts
@@OggaDugga Not Toyotas. Nor was the Ford Triton V8 a Gilmer belt engine. I'll reiterate my previous assessment: Turkey.
@@Flies2FLL lmfao from this era Toyota had plenty of belt driven engines 3SGTE, 2JZ, 5VZ-FE. Instead of dishing out insults, get informed.
I would also like to point out, that even if you have the correct ECU and retain the twin scroll turbo and you are in NA, these engines STILL need a tune, as Eric mentioned.. just the octane difference. I have a JDM EJ20Y car in Canada, and when initially logging the car you would see the ignition timing pulling like crazy, and the power level to be lackluster as a result.
once I got on the rollers, I saw impressive increase of the under the graph area, and massive improvements in drivability.
if your not going the cheap route, this engine is not the one you want to put in your 2.0 WRX or 2.5GT unless you have a plan to deal with the AVCS system, whether it be both intake and exhaust in the bug eyes or exhaust only in the LGT. in legacies you can easily use the TGV harness parts and pin them to a JDM ecu's exhaust avcs control, but those ECU's have immobilizers so you also need to deal with that to run one.
So you have a EJ20Y ? , I also have a EJ20X/Y engine swapped in my wrx (not by me tho). I’m pretty sure the headgasket is going bad. Is there a chance that the EJ20Y headgaskets are different from the EJ20X ? Or are they the same , if you can reply and tell me that would be amazing , I’m having it get fixed soon and need to buy the correct gasket and seal kit. Any advice ?
As in the video he’s tearing apart the EJ20X , but is the EJ20Y different at all ? As in gaskets and such ? Anybody ?
@@eimmiekhim9023 they might have different cams. The block and head castings are the same, so the gasket that goes between them should be the same….
Actually any ej20 turbo head gaskets should be the same. They all mate to the same block surface.
@@funkthew0rld @20:47 is him taking off the headgasket , it has the “A” top . I should get that one right ? Because that’s what they are trying to ask on the email to help me out.
@@eimmiekhim9023 if you’re in the US or Canada, just go on rock auto, search up a 2002 Impreza turbo and buy those ones.
A EJ20 is an ej20. It doesn’t matter if it’s a 205/207/20x/20y/206/201/204.
The top of the block is the same shape. It’s an ej. Simple as that.
For future reference, the upper intake and TGVs come off as one piece. It makes it so you don’t have to mess with trying to mess with the fuel lines and the harness; it all comes off as one assembly.
For the camshaft sprocket bolts, I always just drill them out, since “breathing on them” isn’t an option for an engine that you actually expect to run and work afterwards. Once you drill with a large enough bit, it releases all the tension on the head of the bolt and they unscrew by finger. It’s way easier than fighting with a breaker bar or impact and stripping out the bolt head, breaking the composite gears, etc.
The fact that this has a cork oil pan gasket on it means that the person who installed this engine has never worked on a Subaru before (or any other Japanese engine). I’m surprised they didn’t shellac the head gaskets.
To use a JDM motor what changes are required. Change cams and sensors ?
I’d hope you can find an EZ30/EZ36 at some point. Failures for the 4 cylinder boxers are common, but the Subaru flat sixes are usually better regarded and mostly reliable…save for some that like drinking their 5w30
Any teardown he does I'll watch, but the flat motors are particularly interesting to me, whatever make or cylinder count! That's a roundabout way of saying I'd love to see an EZ teardown too 😄
Subaru has let me down with only 130k miles and dealership oil changes and the engine is burning alot of oil. Not t9 mention dealership keeps damaging the paint job on my car. I'm done with subaru and that is sad since it is a great car except for the engine problems, cvt, and dealership mechanics.
OK, so hear me out! We need to make an engine entirely made from wrist pin material! It would be indestructible!
Happy New Year, Eric! If I ever make it to the USA, I will stop by your yard/shop, say hi, and buy some... art!
Have a great day, Sir! o7
without a failure point the whole engine will leap out of the car when something goes wrong. how you going to explain to nasa where the new crater on the moon came from?
Thanks for doing another Subaru engine. Whenever you do Subarus you always say that these cars are not for YOU. Could you say what you find most unappealing about them. It would help your viewers get a feel for you and learn your preference. It is not just the engines we wacth your channel, its your personality also. Thanks🙂
That's a 2008+ , you can tell by the dual avcs and plastic manifold. You made 1 mistake removing the intake by splitting the manifold from the tgv housings. The come together, then separated after assembly removal
Na, you're on the right track but you've mixed the original donor car and the car it was in when it died.
The EJ20X/Y was only ever fitted to the JDM legacy, and they were all dual avcs, so it could be any gen 4 twinscroll leggy from 2004 onwards (some very early ones in 2003) Other parts have been fitted to it in an attempt to make it work in a USDM legacy, but it's been half-assed.
You set all the plugs together, and my childhood suddenly came back to me. Good old Sesame Street...one of these things is not like the others. One of these things, doesn't belong. Can you tell which thing is not like the others, by the time I finish this song?
Glad I'm not the only one who broke into song.
I still would like to see a 1.8 from a 2016 Chevy Sonic, and a 2.4 SRT4 that came in the 2003 Chrysler PT Cruiser GT with the aluminum intake.
This is my favorite YT channel. I look forward to these videos every week.
Fun Fact:
Subaru once built a Flat 12 engine for F1 racing.
The design was 20 years out of date, was 200 horsepower down on literally every other engine on the grid and 300+ pounds overweight.
It does hold an F1 record for the largest time deficit too the leader in a single qualifying lap.
It set a lap time of just a hair under 8 minutes in qualifying for the 1990 san marino grand prix.
*Life F1 has entered the chat*
Fun fact, it wasnt a subaru engine at all it was some random italian brand that subaru entered into a partnership with and put their name all over
@@wefwefwef.
Actually it was designed by a former ferrari engineer, but it was built by subaru with some technical help from motri moderni.
I’m on my fourth Subaru STI. I enjoy the shit out of these cars.
Contrary to popular internet meme belief, the EJ20 is actually a rather reliable engine. Also very capable for its time. Plus it sounds amazing. I guarantee, whatever your opinion of Subaru, if you ever get to drive a first generation Impreza with one of these in it, you'll get why people love them. Very easy to work on as well, no matter what people on the internet who have never touched them tell you.
I like that the first time I swapped an engine in one of these (because SHE let the oil get low) it only took me one day. I bought the first Subaru because SHE liked them, and then another, but have gained a lot of respect for them. They're not my style, (although I'm driving one now because life happened and I had it) but they're pretty well made and not super difficult to service, unless it's turbo, which shoves a lot of extra stuff under the hood, but even then, they're not absurd.
@@edifyguy Def one of the easiest engines to swap. Glad you learned and enjoyed. Most people just speak based on what they read on the internet. 😂
I’m speaking as a previous owner & someone that has actually rebuilt a couple EJ25s… I’d never own one of these cars again lol. The cars are definitely well made with really nice interiors compared to a lot of cars. The engines however are just garbage. Way too many weaknesses.
@@stevemccauley5734 The EJ20 and EJ25 are different animals in terms of reliability and performance. I personally don't own any EJ25 cars, though my family has had plenty. I do however own numerous EJ18, EJ22, and EJ20 cars with anywhere from 110,000 to over 340,000 miles all on original engines. My aunt also daily drives an Outback with an EJ25 that's nearing 300K I believe, but it has had the head gaskets done. If it wasn't for the damned EJ25 head gasket issues, Subaru wouldn't have nearly so bad a reputation nor as many memes about them. Even the EJ255 turbo engine is more reliable than the NA EJ25. Not that any of them are perfect. The EJ18 and EJ22 were absolutely bulletproof, if slow. The EJ20 isn't quite as reliable as those maybe, but just about, and with so much more performance. Plus I just love working on Subaru more than any other brand. At least the FA/FB engines don't have head gasket issues and are generally very reliable overall. The EZ 6 cylinder engines were incredibly reliable as well.
@@stevemccauley5734 Main weaknesses on EJ-series mostly affect the 2.5's. The 2.0's are actually somewhat more reliable when built because they actually have cylinder wall thickness
Mrs has an Outback with ez36 engine . Those don’t seem to have problems but it would be nice to see 1 apart .
There weren't that many metal bits in the filter because it was clogged and bypassing most of the oil. In fact, that cheap jobber filter would have been bypassing oil even when it was new, since it wouldn't have the Subaru-spec 23 psi bypass, and is probably restrictive as well. This is the case with most aftermarket oil filters available for Subarus. OEM and PurolatorOne are both good options for these engines. A good filter can make the difference between having to do a bearing job and having to scrap the entire engine (well, maybe not in this case).
That sounds like valuable info for those of us not up on Subie stuff...
Trash engines better off never buying this brand.
Subarus are the best!!
Says every single Subaru owner, until they’re engine is on I Do Cars!!!
And it’s junk!!!
Absolutely garbage engine!!!
It would be an honor to have my Impreza engine featured on Eric's video, if it ever breaks. It needs to break first and it ain't broken. Not a problem at all with my engine.
Water pump is for sale?
The EJ20X/Y's a perfectly good motor, you can't really tune it much, it has no headroom but it's really well engineered for the stock job. Dual avcs, big oil pump (what people think of as the high flow sti oil pump was developed for the Legacy), quite high comp, and various twinscroll turbos handpicked to match the engine, mine has 245 at the wheels and absolutely gorgeous drivability and midrange for a 20 year old 2 litre turbo. They're not super durable, but they're not terrible.
But, it's become a weirdly popular choice for swapping into subarus, because it's about the cheapest turbo ej you can buy, but that doesn't make it a good idea. This engine going by the other parts it has fitted has been fitted into a USDM legacy, which originally had a 2.5 litre single AVCS in it. You only do that because it's the cheapest option, so they've almost certainly bodged it in without doing much else- if you start spending the money to do it right, it stops making any sense to start out with that motor.
And the EJ20X/Y is a dual avcs motor, so if you fit it without addressing that into a single avcs car like the USDM Leggy, then what you get is variable valve timing. You also end up with more compression than the stock motor, and a turbo and tune designed for that. So they almost never work properly and then they fail and people go "bloody Subaru!"
It's a real shame because the only people who ever do it are people who can't afford to do the job properly, and that also means they can't afford to have their bodged in engine fail. It's almost always just the last in a long run of bad choices or bad events, because obviously if you're not reasonably comfortable money wise buying a turbo subaru was a terrible idea in the first place.
TLDR don't put an EJ20X into your 2.5 litre subaru. Don't put it into your older 2 litre subaru. Don't try and tune it beyond about 300hp on the stock internals. But don't blame it for not being the right part for you. DO get a JDM twinscroll gen 4 legacy wagon, if you can, because they're ace.
The one Subaru I ever had (and bought new) needed $6000 worth of work at only 145,000 miles. So much for Subaru “reliability”…never again. FYI it was an ‘07 Impreza no turbo.
I bet you needed a new transmission. Today I saw a subaru accent, huge vehicle,yet with a cvt.
Its insane to me I’ve never had any issues with ej motors, all mine are usdm, and im not saying they are perfect, one leaks oil really bad, yet my brand new ford 3.5 eco boost f150 blew up, i have 2 19 year old ejs one with 205,000 miles the other with 225,000 miles the f150 had 11,000 miles, i am a subaru guy so maybe because i check my oil so often? I also have a fb20D subaru impreza
I have a friend who had worse cam caps, cams, and journals than those that he cleaned with sandpaper when he did his "rebuild" and that little dodge neon engine is still running 6yrs later no problems. I dont reuse cams, journals or caps that bad. I bore them out, install oversized cams that some companies sell for this type of work, then finish my rebuild. Those engines never have issues when i do that. But ive been waiting for his engine to die so i can rebuild it correctly for him 😂but it hasnt happened.
How do you do that? It would be a "blind" line boring operation, with the caps installed on the head.
Most "block" line boring equipment is not made to do a blind hole, and is for much larger crankshaft main bearings.
Who makes cams with slightly larger bearing journals? I have only seen large bearing cams for v8s, where stock bearing diameters can limit lobe lift. This unique problem does not apply to engines with removable cam bearing caps.
What you suggest is not impossible, but is a VERY strange, unlikely solution to a problem better solved by cheap brand new parts.
The EJ20x is not a engine to modify. That's probably the worse one to import. Somebody was driving the crap outa that thing.
I will never understand the appeal of Subarus.
As someone who's put 400,000+ miles on 3 different subaru EJ engines that I DID NOT BLOW UP, I can assure you they're fine motors and that the problem is user error always going WOT in high gear on huge amounts of boost. bye bye rod bearing.
Subaru owners just need to accept replacing the engine is considered a routine maintenance item
So that's part of the problem, the owner of this USDM 2.5 litre car has treated the engine as a disposable item, so they bought the cheapest replacement EJ they could find, a JDM 2 litre with very different spec, and they've fitted it badly. And then it's blown up and they've gone "bloody subarus!" instead of "ah that's my fault, I did that".
In their original home, with japanese fuel (or a proper remap for US low octane) they're great- reliable, not too stressed. You don't tune em, they have very little headroom. But as an engine crammed in a hurry into a US car? Just a bad idea. But you only do it because they're dirt cheap, and so you fit it badly because that's all you can afford to do. If you could afford to fit it properly and retune and deal with teh dual avcs etc, you'd not start out with the EJ20X/Y in the first place. So it's chicken and egg but almost every time one of these motors gets put in a US car it's a bad idea.
I see another man of culture went on Amazon and bought the 40 piece hose clamp set...and decided to use them all on this engine 🤣
When you're tearing down a 500 hp v10 and It's destroyed a piston, that's one thing. After all, you still have 9 cylinders and 450(?) horsepower driving what's left of the engine. Inspection ports and piston gravel can be expected. When you're tearing down a flat four with 200-400(?) horsepower, you only have 3 cylinders and 150-300(?) horsepower driving what's left of the engine, piston gravel is kind of a surprise. But then the keyword here is 'turbo'.
I put a JDM into my Forester. I had to swap out a few pieces. It wouldn't start until I swapped the left cam gear. Runs great since, and no more head gasket leak.
Which jdm motor did you put in ?
@@eimmiekhim9023 It was an EJ25. I don't know which series. It came with an electronic throttle body. I had to use the old one.
Basically, It was a long block with some extra parts I couldn't use.
I found it on Ebay for about $2500
Come on, stop acting like all Subarus do this. I've literally never seen this happen before. It's usually cylinder 4.
The clamp was one that had a thumb screw on it. I use them on my aquarium hoses that have to be taken on and off frequently.
That explains the square head lol. Thanks.....I was pretty baffled by that.
The oil filter brand says it all folks……
Great teardown! Loved the Rod Serlingesque intro
Knock knock who’s there……head gaskets… OK OK I I can rag on Subaru I dally a EZ36….
That block off plate on at 17:20 ish looks like it is for an ej206/208 second turbo line, I am not sure as I have not been hands on, but I know many people convert the twin turbo ejs to single for simplicity and reliability (the PCV system is a nightmare, and the exhaust headers are overly complex)
The oil port for that second turbo is lower on the head on the ej206/208.
This motor was a single twinscroll turbo from the factory, the previous gen legacy was twin tub.
Unpopular opinion, these are amazing engines that got cheap enough for people that were never going to maintain them to get their hands on. 100% of failures on these ive ever seen have been poor maintainance related.
This was a awesome teardown
"Now this is what makes a Subaru a Subaru". 😂😂😂
Excellent! Another Saturday, Another engine teardown! 👩🦳
Subaru owners are very vocal about how great and trouble free Subarus are. But when they blow their engines and the CVT dies, they go off the grid... These are some of the worse cars made in decades.
Uncle Rodney's back just in time for New Years!
Those lesbians sure are hard on their Subarus.
Speaking of smashed spark plugs, (not really smashed, but more like broken) my dad was trying to start a Stihl concrete saw one time, it wouldn't start because it didn't have any compression. He pulled the spark plug out, and the ceramic part of the plug had completely separated from the nut of the plug! I still have that spark plug to this day. It baffles me every time I look at it.
Thanks for reminding me, once again, to NEVER even consider buying a Subaru car.
that water pump toss was absolutely perfect! 😂😂😂 i haven't laughed that hard in a while!
This leads me to my next question as a fellow Subaru owner *****part out ***** Eric??????
Absolutely fascinating how this engine was designed.
Pretty much a Japanese Porsche with different issues
I agree - there are so many big and little ways that the boxer layout makes assembly harder.
The items I had never thought about were the gudgeon/wrist pin access ports. Not a solution used in the VW engine. But it has separate cylinders.
Fascinatingly bad, yeah...
Exactly fascinating trash. Screw sub for using this boxer trash. I think i hate this engine more than mazda rotary trash.😂. Sube is trash and waste of good awd id say theyre multi generational sobs. Right up there w trash dodge.
Subaru should just abandon the flat engine. I dare say the Solterra will be more reliable than anything else in their lineup this year simply because it doesn't have one.
Best water pump gag so far 😂
10 minutes in and this is already a favourite video. Eric is in a good mood, eh?
Hello from Australia!
Well that explains why the end of that spark plug was dished. The wrist pin slammed into it. By the looks of that bad head that engine was turning pretty fast when it decided to take an early retirement.
Thanks for the carnage, Pete!
It will always baffle me how a brand that makes so crappy engines, can have so many ardent fanboys...
Many years ago, I knew a person who replaced his Japanese car engine with one imported from Japan. He told me that due to inspection rules in Japan and other factors, cars are not kept long in Japan. This is the reason that low milage imported Japanese engines are available.
That is true. Also, people in Japan hardly need cars to travel in the city. Traveling outside the city, they may use a car, but even then, their travel distance will not be large due to living on islands and can only go so far.
Exactly right. This motor is out of a gen 4 Legacy, a ton of those get exported to the UK complete as we're also right hand drive, but there's so many that it only makes sense to export really nice condition cars. If it's got any amount of damage or wear or rust, then it makes more sense to scrap, and then a lot of the engines end up in the US for dirt cheap, and fitted inappropriately into the wrong cars, like this one. It's a sad end for those almost-good-enough cars!
You should try to do an fb20 out of a 2013-2017 Impreza or 2103-2018 crosstrek. Those engines had a recall on valve springs. Maybe you could find one with broken springs.
Eric, what brand disposable gloves do you use? My wife and I are pretty impressed with them!
Also, you chose an engine from the perfect brand to deliver destruction!
Good to see that the factory Oil pickup survived the destruction. They are known problem area.
A video on recycling would be cool.
That was close man, I was THIS close to unsubscribing because there was not enough destruction to slake my thirst.
It's not that Subaru boxers are prone to fail. Great points about just buy cheap to go fast... lol It's also that tubers try to make them 600 HP drag machines and everyone either modifies them beyond intended spec, or don't treat and maintain them well. Pretty spectacular that NY 'pop' must have been.
Agreed. Also a lot of bad info out there and memes. Plenty of NA Subarus out there doing 300-400k+ miles with good proper maintenance.
Yup, in this case they've shoehorned a 2 litre dual avcs engine into a us spec 2.5 litre car, badly, and so it'll have never worked properly. There's no way the owner will have tuned it for us pump fuel or addressed the turbo and compression changes (I say that for sure, because absolutely nobody would fit the dual avcs and leave the exhaust avcs in place but disconnected as they have here, but do a proper tune). It's a bodge from top to bottom and no wonder it ends badly.
Subaru engines are definitely like that. When they have a mechanical problem, they go downhill fast.
Subaru owner here who's been through it all: Wouldn't mind having some of those parts to add to my Subaru museum of destruction in my garage, which currently includes such popular displays as the grenaded viscous coupling center diff, transmission gears stripped of most of their teeth, and roller bearings that spit out pieces of circlip when you spin them. As for the reason this engine let go, I'd guess low oil. It doesn't take much wear before they burn a quart of oil every 150 miles, at which point it's only a matter of time before you forget to check one day, and then bam. I was told the reason we see so many JDM engines in the US is that for cultural reasons, the Japanese people who own cars will only buy new ones, and only keep them for 5 years. So any JDM cars over 5 years old are simply sent to scrappers, who part them out and send the stuff everywhere but Japan.
I've heard of oil consumption issues with Subaru's, but haven't experienced it myself. My '99 Legacy doesn't burn any oil. I bought it new and have done every oil change except the first with Mobil 1.
In 2018 when a head gasket failed (imagine that), I pulled the engine as it was close to 200k mi. and figured I'd tear it down for a look. Heads were great. Machine shop surprised how good they looked. New stem seals. Crank was polished and bores honed.
Another 5 years of driving. No oil consumption and the head gaskets are holding 😅.
@@timsilva1944 My goodness. You took good care of the engine, took it to the machine shop to clean everything up for the head gasket job and your engine is like brand new again. That's the way.
@@timsilva1944Good to hear the '99 held up pretty well. My 2010, which I maintain religiously myself since I'm a former mechanic, was using 1qt every 200 miles at 140k miles. The rings were shot with extreme cylinder scoring. It had been drinking oil since 50k miles, was never run low, and I always run top of the line synthetic and oem filter. We kept driving it that way until the head gaskets decided oil and antifreeze should mix. On the plus side, the rebuilt engine we have in it now runs perfect and doesn't use a drop of oil.
@@nowiecoche Thanks. Head gasket blew right after I replaced all 4 struts, lower control arm bushings, CV axles and front hub bearings. 😡
I wasn't too keen on replacing head gaskets with the engine in the car, so I figured why not freshen it up.
It's a manual, so a new clutch was a given at that stage.
It sounds like you could have your own channel of Subaru carnage.
Love to see a ford 7.5 gasser. I don't miss fueling mine up but it was such a reliable workhorse
This has been interesting to me, and I appreciate the information you've given, because I was one who'd always thought of Subaru as a completely bulletproof engine maker. I guess we all can respond to marketing stupidly.
I still have high regard for the carmaker (I've been a big fan of the boxer design, having owned two Corvairs), but you've given me much to consider about Subaru.
for what it's worth this is mostly a combination of poor aftermarket rebuilding/assembly and a negligent owner.
Bullet proof or not, you still need to service the engine.. oil change, belt, spark plug change, pumps, gaskets etc. that's where it gets tricky with the boxer engines because of the way it sits, it can get labour intensive. By the time second and third owners they just "let it ride".
PORSCHE INVENTED THE FLAT 12 AND 6 AND 4 ENGINES AND SUBARU ENGINES ARE SHITTY COPY OF SOME AWESOME ENGINES!!!!
Thanks to both of you for those valuable comments. I had originally not realized that he was working with a reworked engine here, and that the topic was about second hand examples.
But I've gathered that there are certain weaknesses in Subaru engines from the beginning, if you're not following every model and don't do your homework.
@@bretfisher7286 If you want bulletproof and subaru... you want the Ez36R. Unfortunately it was discontinued in 2019
They make great VW bus engines…..that’s about it….
I've often thought about using a double worm type hose clamp(s), but never actually did it. Good job 👍
We need some big displacement destruction, they never seem to disappoint in the carnage department that's for sure lol P.S. Still patiently waiting for something to displace 8.0L Magnum V10 from its crown because it had *EVERYTHING*
Coincidentally, I put an 8.0L Magnum V10 in my Subaru Impreza. Does that help?
Ej255! Ahhhhhhhhhhhhh. Love you buddy. Glad it had carnage!
If that was you guys who provided this gem, THANK YOU!!! Would love to hear the backstory on that core.
Also, have enjoyed chatting with you guys on the phone in the past re: a non-Subie motor I was trying to find. Cheers!
@@miketdavies it was us. Honestly... I forgot what core I sent Eric. But this one came in as seen in a parts car. So no cool backstory.
Thanks for my Saturday night entertainment Eric. Happy New Year to you and yours.
I had no idea they make a high compression engine that is Split Block.
I dare say, What a Stupid Idea 🤡
Enjoyed the mess and over-engineered tear down 💪
What is your opinion on Porsche's turbo boxer engines? They're also high compression and "split block".
The split block is almost never an issue, the actual interface is stronk.
Yes the japinese make a superior product. My mazda is proof of that
Eric I am surprised you haven't been scouted by MLB scouts!! Thanks Pete for the fine specimen!
