Check out the Subaru EA engines. The pushrod engines I describe as like someone described an aircooled vw over the phone to an engineer. The transmission (that became the 5 speed) is very similar too. The ring gear ID is even the same, and dimensions close enough you could retrofit a subaru diff into a VW (I've considered it).

Bonestock isn't good unfortunately either. Best results I've seen are quality built motors by a builder that truly knows subbies like Mike and how to properly build and measure/spec boxer engines out, and just mild performance levels of tune, so building them stout and then running within 15-20% of the stock levels, the engine is barely being pushed more than stock but still wakes them up. And then quality aftermarket parts, fasteners, and the engine built slowly by hand instead of a assembly line, fully blueprinted, balanced, and torque plates + arp fasteners and ATI or Fluidampr balancers and better headgaskets and then either custom closed deck plates or epoxy fill, unless using one of the less common closed block decks they have. Then stringent oil and coolant changes according to schedule for severe maintenance schedule. And the best tuner you can afford 😂.

I've almost always attributed EJ early death's to oiling problems in their stock forms. I'd not considered the ring issues, which is a solid point. Unlike a traditional layout design--where other fluids to include a gas/air mix doesn't mind laying on it's side nearly as much--the oil travel and performance certainly does!

One of the best videos I have seen on just explaining issues with an engine not just because it’s a Subaru motor. A lot of what was explained can been applied to many motors especially the part about using head studs. My hat off to you sir for letting the you tube community understand about what happens to your cylinder bore when using studs. A lot of fools who think they know how to build or solve head gasket problems think that head studs is the answer. Using studs will help prevent blowing head gaskets especially on a diesel engines but that cylinder distortion will result in a shorter engine life. I drive a 2003 F250 with original head bolts and gaskets with 420k mileage on it currently and will hit half a million this year. Wouldn’t be able to go much past that with head studs and not start using/burning oil.

Well done. I enjoy watching someone who absolutely knows what they are talking about. Unreasonable expectations on what was originally designed as a family car into a turbo charged monster will cause problems and expensive disappointment. 61hp/liter for the stock NA engine to 121hp/liter for the factory STI and then expecting up to 320hp/liter to be reliable is a pretty good stretch as a reasonable expectation. LOLOL!

Well said and perfect detailed info we all needed to know. Thank you sir. Your the best :)

The main thing is don’t drive it like you stole it. Let the car warm up, check your oil, change your oil, do your preventative maintenance and follow that scheduled maintenance they give you in that little book in your glove box.

Really detailed and comprehensive report on EJ issues. I lost my 92X motor at less than 30k miles still under warranty and Saab/Subaru wouldn't cover it. Haven't trusted them since. The FAs are a little better but I still won't track one without the recommended mods and they are farther down the list of desirable cars for me.

I find it so surprising the variance in experience. My family has had a LOT of Subarus but never had an engine go. My sister even had the timing belt slip on an old Impreza hatch I think and it drove to their garage and it didn't damage the engine (amazing, we thought anything happen to timing belt and engine is toast). I think the main difference is we've avoided turbos and aren't racing / tracking our cars, we just want pretty reliable really good AWD and good in the snow cars. We have had the head gasket issue, but they're not that bad to get fixed or if you're buying used, just buy ones that had the gasket changed already. I'm pretty sure they finally fixed that with the new engines. What I did have go wrong was the newer CVT transmission. I decided to keep a car due to not driving all the time, and at 55k miles the CVT started slipping. Luckily for me - Subaru is covering it under an extended warranty(not something I bought, I guess they just did it for everyone because of some issues.), so I have no real complaints - they're dealing with their bad part, no hassle from me needed. I get to drive a new Outback while waiting for them to fix mine.

Sounds a lot like the denied warranties for the FA24 motors that are in the GR86/BRZ. I nearly bought a GR86 myself but the more research I did the more I realized that I don't make enough money to tank a totalled engine block in car that has multiple known ways of totaling the engine.

FA's are extremely stout, significantly better than the EJs. Quite a few people making a lot of power on unopened FA's these days

Great honest Vid! Many years ago I came close to buying an STI Bug Eye. A good friend / Mechanic schooled me on the benefits of an iron, closed deck block. I went that route (4G63). 15 years later, still making good ethanol power.

Love this guy . So professional and super educated. ❤

I like how this guy gets to the point so quickly and simply.

Excellent advice.

Subaru engineers has to hire you and listen very carefully to improve their engines.

They don’t care. Prior STi owner and current Type R owner now. I dunno, they just lost it.

This is soothing to my former subaru enthusiasm and my short but extensive engine machinine past.

Most of my wife’s family buy Subaru’s only. They live in Montana and buy them for their superior traction, safety and accident avoidance. One of my brothers and sister’s inlaw drives 50K miles a year, so every 6 years they buy a new Outback, because after 6 years it has 300K miles. They change the oil every 5K miles and every 35 - 40K miles they have the CVT fluid changed. All of her miles are highway mileage where they seldom drive over 70mph. A few years ago my wife had been wanting an Outback for many years, so for her 50th birthday I bought her a 2 year lease returned Outback. It had only 5,600 miles. It now has only 30K miles and it’s 5 years old. She fell in love with the Cinnamon Brown with the warm Ivory interior. Before buying her the Outback she’d have to park her Camry 3-4 months every winter because of the 5-7 feet of snow we get here in a very mountainous area of north central Washington state. She would then drive my 4WD Toyota RAV4 and I’d drive our 11 Ford Ranger XLT super cab 4WD pickup. After buying her the Outback, we were so impressed with the traction that I decided it was time to replace my old RAV. We had to put studded snow tires on my RAV every winter, whereas she drove year round on her factory tires on her Outback. In December 2022, I found a 2019 Forester Touring that had only 4,700 miles. It’s a Certified Subaru and is the biggest LEMON ever produced. I started complaining about it at only 5K miles and BEFORE the Factory Warranty expired. It’s been into Subaru service department many many many times. They thought that they found the problem After the warranty expired and even though I’d been complaining about it for over a year and the warranty expired, Subaru wouldn’t pay to have it fixed. So it cost me $1,600. Even though I spent that money for a new DCM the main computer, it’s still doing the same things and now my mpg has Dropped from 24mpg, it’s now down to 20mpg. It’s the 2.5L 182 naturally aspirated engine. Hell, my RAV had the 268hp 3.5 V6 with a 5spd automatic transmission and I was getting 27mpg in it. In 25 the RAV. Is supposed to be redesigned, so I’ll wait for the 26 year model and I’ll sell my POS LEMON forester Touring and buy a new RAV AWD Hybrid. My Forester is my First Subaru and it will be my LAST Subaru Ever ! As far as I’m concerned, Subaru can go 🖕🏽🖕🏽🖕🏽 Themselves

My buddies VB almost blew up a few days ago because his turbo oil cooler (idk its technical name) had the two bolts that seal the gasket on the bottom of the turbo completely back out and cause a massive oil leak. No low oil warning just a shitton of smoke. When we took off the metal undertray, there were 2 bolts just chilling standing straight up like a cartoon. We realigned the gasket and put the bolts back in. It had lost 3.5 quarts of oil lost in a matter of minutes.

Fascinating Fluent, clear, concise. No wasteful , slovenly, gimmicky talk. No one trying to be a comedian. Just sound, straightforward, totally unpretentious presentation and so nice to listen to. Here is knowledge, experience, sound mind, that is blest with the gift of communication. I’m from a large bore, slow speed marine engineering background with a life long interest in engines, so some of this was way over my head, but it didn’t diminish the pleasure of listening and watching. When I commenced my apprenticeship, an “ old hand” said when he was a young engineer, his elderly chief engineer said to him, “Never forget, engineering is the science of exactitude.” This man is the epitome of that. Love the blend of old school thoroughness applied to state if the art technology. My own interpretation is that accuracy is a pre requisite, not an optional extra. I saw and heard that here. Well produced video. Thank you so much for a brilliant, relaxed and relaxing video.

I love this guy. He's either just in from a surf session or blew up a fattie. He can barely contain a chuckle as he explains what will become "I told you so" for many who can't understand why their 550+ hp motors. But so clear and concise, with a fab vocab.

Awesome video!

It would be interesting to compare side-by-side a stock Subaru engine with a stock flat Porsche engine to see how Porsche reinforced their castings.

@@danmarjenka6361 why not, they did the BRZ (or something similar) together. The head gasket thingy that is popular to say of "all Subarus" aren't true of all engines tho. I would like stats on the longevity of all manufacturers cars in "percentage of distance travelled" or something similar with price included in calculation. Often stats like that even things out.

First thing I blew on my STi was the crank. Must have been that distorted machine work you mentioned. Thanks for the great overview!

Mike - You popped up in my KZread list and I watched this video to the end. I smiled and chuckled to the end. It took me back to my younger days when different things were important. To be honest I looked up the Honda K series and the motor my 2004 Civic. I prefer the Honda D series motor it runs fast when I need it. Parts are easy to get at. I changed the timing belt and water pump with a super stock timing belt and pump (just a Gates replacement kit bought on Amazon) and now it’s ready to keep going at +225k miles. I plan to watch more of your videos, you are very entertaining. Take care.
