Todays teardown is the very first after my staycation while my wife and I had our second child. Everyone is doing great! I wanted to start off with a bang and I decided this Subaru EJ255 was the perfect core for tonights video.
This engine is a 2.5L DOHC Turbo Boxer 4 cylinder. Makes about 250hp in stock form though most get modified. Iterations of these engines came in a TON of subarus including the Baja, Outback XT, Legacy GT, WRX and Forester. I cover some common failure points along the way but the situation that led to this engines demise could have been prevented as most of my teardowns prove.
Why am I doing this? My name is Eric and I own and run a full service auto salvage facility in the Saint Louis Missouri area, and part of our model is tearing down blown engines and salvaging good parts from them.
I hope you enjoy this teardown and as always, I love all of the feeback, comments and even the criticism.
Catch you on the next one!
-Eric

Congratulations on a healthy baby and mother and let's not forget Dad, who's doing lots of extra chores nowadays. Aren't diapers fun? That engine has enough salt to serve a small town's needs all winter long. In lieu of Eric's breath, a modern heat gun puts out a lot of BTUs as well. As you expose these more-complex engines, I'm more appreciative of my slow-revving V8s with carburetors and VW air cooled engines. Have you opened an inline 6 cylinder engine? I enjoy seeing all the tech inside these engines as well as your banter. You're appreciated! 😀

I've had a 2005 legacy GT with the turbo engine like in the video for 14 years. I've programed the factory ECU for a bit more boost but not push it too hard, just an extra 30 hp and 60 ft/lbs of torque. But it's completely stock. I've always changed oil every 5000 miles with Rotella T6 synthetic and high quality filters. Now it has 130,000 miles. All I ever had to replace where two injectors, a worn out clutch, starter, PS pump and struts. Mostly maintnace items.. I live in Alaska and our winters are quite harsh but this car has been great and has never left me stranded. Although I do have to admit it's orientation makes it a huge pain to work on sometimes. After watching this video I would never want to rebuild one. The design seems very pointless compared to the simplicity of an inline 4.

They’re usually very cheap to own up to around 90K - 120K miles then you’re in for plugs, timing belt, usually water pump and tensioners, etc, and those are labor intensive jobs on all boxers. And, if you’re unlucky you’re also in for head gaskets which is even more expensive. So I tell people to get rid of a Subaru before 90K unless you can do all that work yourself.

@@sharedknowledge6640 Timing belt, water pump, tensioners etc. are all common wear items for any motor with a timing belt. It's not just a Subaru thing. Labor depends on the model, some models don't have as much space so radiator removal is necessary but some have enough room that you can do the entire job right there in front of the car. Head gaskets are annoying for sure, that's a motor out job for sure. Spark plugs are easy on the SOHC models, the DOHC models are a bit more of a pain but with the right tools (lots of little wobble extensions) and if you develop your own process it's not as bad as some make it out to be. The only things you really need to remove are the airbox, battery and depending on the model an air pump or washer bottle. All are easy to remove and reinstall. The problem with these turbo EJ25s is they're very finicky with oil (weight and quality) and hate abusive drivers. Not just lack of maintenance but abusive driving like lugging the motor in a high gear (bye ringlands).

@802Garage Жыл бұрын

@@samuel5916 Wow 250K it's broken in! If it's an H6 all you need to due is diligent maintenance, as with any car, especially oil changes. Don't use 0W-anything would be my advice, use at least 5W-30. Make sure you get the coolant changed once in a while too, like every 50K miles. Same with auto transmission fluid. At least a drain and fill every 50K. Timing chain should go foreverish. If it's a 4 cylinder, you have one of the last of the naturally aspirated EJ25 years. If it hasn't had a head gasket done, then likely it's good to go long term and you got a gem. If it has been done, then it seems it was likely done right so don't worry. Rules are the same, diligent maintenance, timing belt should be due at 300K, but check when it was last done if you can. Keep the battery terminals clean and make sure your ground straps are all in good shape. Enjoy!

As a Subaru owner from Pennsylvania, I'd like to take a moment to confirm this is the norm for crustiness outside of the car community. Pennsylvania roads, or the deer trails we pass off as roads, are notorious for killing cars. Rims, suspension, engine components, body work, really all of it. The glass suffers from the anti skid used through the winter too, coal trucks kick it up badddd. I know from the two windshields I've replaced. Nothing is sacred in PA when it comes to winter and your car. But hey... we have autumn colors... so there's that I suppose.

That's my engine! Thanks for tearing it down. It really helped me get a grasp on component location and whatnot. Yes these are high strung engines. If the oil is not maintained properly it will let the magic smoke out. They aren't forgiving in that sense like a 22r. That said, mine is bone stock over 180,000 miles, and does need the spark plugs replaced. Yes they are on order. It burns/leaks about a quart of oil every 1000 miles or so, so I do have to monitor oil level regularly. That said, when you hit the throttle it gets up and goes. Thank you for letting me know about the banjo screens on the VVT lines. I didn't know about that one but already deleted the turbo screen. My goal is to get 300k out of it. 2005 Outback XT.

Yep looks like all the neglected northeastern Subaru engines I've seen, and I've seen a lot of them. Contrary to internet memery, they can be great engines in general and they are quite easy to work on. Subaru in general is one of the easiest brands to work on according to me and many mechanic friends. All the misinformation comes from people who have never worked on them because, let's be real, they aren't as common as other brands and most people never do more than spark plugs themselves. Agree with you on Alan bolts. One trick I saw is welding a spare Subaru axle nut to them and using a 32mm socket, hahaha. Hot breath you've got there! My first suspicion with these engines is blown turbo due to neglect or because the banjo bolt oil feed filter you mentioned has clogged and starved the turbo. Yours was probably on the second turbo and the filter was removed. There are things to know about these cars to keep them alive long term. Exhaust studs usually come out of the heads at least. Part of the reason Subaru has a reputation for rust is exactly what you see here, rust. They were, for decades, primarily sold only in the northeast and in snow mountain areas. If a brand is almost exclusively sold in areas where cars rust badly, the brand will have countless examples of rusted cars. In my experience, every brand rusts out up here in the Vermont mountains. Subaru is no worse than most. So this engine looks like hell, and people will blame Subaru, but it's just a result of the environment. I obviously know you know Subaru. Engine looked quite clean and nice inside. Wondering if the scoring was from the catastrophic failure or if it was damage over time. Could have been neglected and then owned by someone who actually changed the oil regularly. Given the modified intake, makes me wonder if it was a typical throw an Accessport on it, turn it up, and pop a piston or rod deal. In the end, oil issue makes sense. Most common reason for any engine failure really. Gotta keep it lubed! Clearly at the end it's revealed you and I had a lot of similar thoughts. I was writing this while watching. Fun teardown. If anyone read this whole comment, try working on a Subaru sometime. You'll like it!

@@jeffryblackmon4846 If you've never tried, you would be pleasantly surprised. I am not joking when I say every mechanic friend I have agrees they are far easier to work on than most brands. The only regular things that are a bit harder are spark plugs and timing belts, and even those are basic. Stuff like accessory belts, starter, alternator, power steering, AC, exhaust, axles, sway bars, radiator, the list goes on and on, all easier than most brands. Working on a longitudinal engine is just so much nicer than a cramped transverse engine stuffed up against the firewall and tire well.

I used to be a DOT surveyor. As a part of the job, I had to do a lot of surveying of active traffic roadways. Many times, I'd hear horrible sounding engines that sounded like they were beating themselves to death. I'd turn to look, and more often than not it was a Subaru. I wouldn't take one of those things if you gave it to me. I'm amazed that other people actually buy them. SMH.

@@budlanctot3060 I have a 2000 Subaru that my wife drives because she likes it. I bought her a 2004 turbo one which she's yet to really use because it needs some TLC. The one she's driving now is on its second engine, though the first one did NOT fail catastrophically; it developed a knock at certain engine speeds and loads because she allowed it to almost run completely out of oil, was driven gently for quite awhile with a knock (albeit with oil in it), then I dropped in a used engine. I will say that while these are very ODD engines, and at their best they sound like junk, they really are pretty tough and if you're not neglecting and/or racing them, they actually seem to last pretty well. They're very popular around here because they're an affordable AWD vehicle, and we get unreasonable amounts of snow. I don't mind them at all other than yes, they're a little cramped for surgery, and yes, many years after the engine was initially designed, complying with governmental insanity has resulted in some necessary stupidity, but I still like them. That said, I like my Chevy 350s better ;)

It's sad, because the 90s EJ18, EJ22, and even EG33 were downright bulletproof. Subaru earned a reputation for golden reliability and many diehard buyers. Then the fire nation attacked. Wait... I mean then the EJ25 came out. Really if it wasn't for the faulty head gasket design, Subaru memes wouldn't be anywhere near as prevalent.

LMAO! "I'm sure this piston was burning some oil." As a Subaru owner, and mechanic. All Subaru's burn oil. New off the showroom floor. It is even in the owner manual about oil consumption. 100% normal. Note to all Subaru owners out there that don't know this already. Check your oil every time you get gas. Change it every 4500 mile (not 5000), and always use synthetic oil, and add Lucas Oil Stabilizer to get the most life out of your engine. My 2003 Forester has over 200,000 miles on it, and still going. Also if you get the head gasket coolant issue in the corner. Replace the gaskets with the Turbo MLS type head gaskets on the none turbo cars, and never worry about that issues again.

@francistheodorecatte Жыл бұрын

turns out laying the cylinders flat makes oil scavenging really hard! the solution to the oil burning on my 2013 crosstrek was to switch to 5w30 oil, and beat the snot out of it to make sure the oil rings are slinging the oil as hard as possible. now I get ~1,500-2,000 miles per quart.
