Subaru Engine #3 Teardown 

We call it a teardown, but let's face it. This is an autopsy

"Not only did I wreck. I wrecked wrong" I feel that.

You need to have a whole section where Justin durability tests tools with his super strength.

Whoever did the animations needs a huge bonus

Jeremiah really is the type of guy to go “mimimimimimi” after every snore.

Justin really has come into his own now, definitely much more comfortable

Every time James talks about this event you can see the pain in his eyes and it makes me feel so sad!

Justin became such an integral part of donut. Always an uplifting smile and chill attitude. Thanks you guys.

We need more of these two, they seem to work really well together

James: "This was embarrassing and I don't want to constantly relive the moment" Donut Fans: "This is the content we crave"

Justin has definitely found himself in the newer videos. It's great to see his progression.

I just want to say I really appreciate what you guys do. this is stuff my buddies and I figured out over the years. I grew up in BFN and my dad was a mechanic and I picked a-lot of it up from him and used to show my friends who wanted to do car tuning stuff like this. I really love that anyone can now have the ability to learn about cars and racing on a budget. It makes me happy seeing the younger generations keep the motorhead mentality.

Justin has really come into his own. He used to seem nervous, but he comes up as very comfortable on camera now. It really feels like he's one of the crew now.

I fucking love these episodes! These autopsy pieces where you examine an engine you destroyed in HiLow are so educational! Thanks for more of them!

I feel like Zach could be a professor in college, and we could all sit in the class not bored for the whole session. 😂

Love these teardown/autopsy videos. I would happily watch an entire series of you guys getting junkyard engines and digging through their guts!

finally this is the type of episodes I look for when watching donut media, you guys are great at explaining both what happened and the process to discover it

Jeremiah is the type of dude to float when he smells a fresh baked pie

I love to see how Justin is becoming more and more comfortable and his personality is really showing. The Donut Crew is the best!!

Love to see Justin continue to get more comfortable on the channel. Great video, really enjoyed this one especially. Good work as always donut!

The upgraded oil pan point was a revelation. Thanks for that. Some of us were assuming that oil starvation was the common denominator, as you well know. Glad you're going through this; nothin isn't content.

“Accidentally going backwards” is what I’m gonna call all of my accidents from now on P. S.: Justin that “Welcome To Donut” at 00:32 was the smoothest thing I’ve ever heard

Excellent explanations of the various dissection efforts, and great energy between Zach and Justin. MOre of this type of vid please

This is actually awesome. So many people have no idea how to diagnose problems. Very educational and helpful. Good job donut dudes

A car channel doing car things. Love it.

This is the best episode of donut in months!!! More like this!!

Wow... I have never seen a post incident engine tear down like this before, and learned a couple of tricks for diagnosing issues during a rebuild. Thanks guys!

The oil pan part was a shot at all the channels that hated on their build 😂

I’m sure everyone was so relieved when the boss crashed and none of them 🤣

Daddy jobe and Justin doing more technical stuff together is great, we need more of this stuff

i am so grateful for you guys to experience this, figure out everything possible around it, and then provide how to avoid anything negative in the future. seriously the donut team is a god send in the car community and honestly should hold a higher stake in it's influence asap even though the influence is already pretty massive lmao

this show has made me wanting to get back into mechanic school. this show is so good and informative

It feels illegal to be here so early. 😮

This was a really good episode, I love when you guys do tear downs and explainers

Awesome videos guys. This one was especially good. I am able to learn so much from you guys. Thank you.

Justin dancing in the dark during the valve autopsy was amazing. Thanks for being you, Justin!

the low-key oil pan callout 💀

Love when you break something and dig into what happened, its cool learning what went wrong. Thanks for the great content!

Love learning how engines work, and more importantly how they fail. Great chemistry between Zach and Justin.

Freaking LOVE this channel everyone is so cool and you always learn alot, round of applause for how hard everyone works to crank out as much stuff as yall do!

Salute to you mr. Zach i'm an automotive apprentice and i'm learning a lot everytime i watch all of your donut videos! Cheers to Donut!

these autopsy episodes rock - you learn so much

Great video. These kind of videos are why I watch Donut… I learned a lot.

Thanks for doing this video, lots of questions around how these engines were built and this puts all the speculation on the oil pan/baffle issues to rest.

Yesssssss Donut media with the Engine biopsy . Love it . Really shows the engineering ability and overall learning experience of what all went wrong and what can be redeemed and learnt from it . Gotta be honest really "expensive" knowledge we learnt from the Subaru hi low season . Saying that , we NEED A NEW HI low SEASON

Crazy! I expected WAY worse inside there based on the sound. Too early to tell but it honestly looks like you probably could save the block at least, with a thorough tear down and crank check/rod bearings etc. The damage of the instance itself isn’t bad, I’d actually be more worried about bearing damage from metal shavings.

I love these videos. I learn so much. Keep em coming!

Justin is more powerful than all the engines used in this high low season combined 💀

I actually enjoy these videos the most. Not only is it a teardown but you explain it the best.

This was a fantastic video. The content, the chemistry, all of it.

The perfect teardown team! Zach and Justin

FYI, one of the most basic tenants of aggressive/spirited/track driving, is TWO FEET IN, and don't steer, during a crash. Push in the clutch, push the brakes at the same time, and hold the steering wheel steady. Most wrecks are made much worse when the engine is still engaged to the wheels (extra forces the tires have to deal with, and as you see in this video, potential engine damage) brakes arent used to scrub speed as much as possible, and the driver wildly turns the steering wheel around to prevent the crash...which usually just Scandinavian flicks the car, flips it, spins it worse...etc.

I love how you can see Justin’s growth I remember when he first joined the channel, I’m glad he’s more comfy on camera :)

You guys assembled the best and most entertaining team! Amazing job, 🍩!

I find these videos so interesting and informative! Nice work Donut!

This was a great video! Thanks guys

I really like these episodes with Zach and Justin. They are always entertaining and informative.

I was wondering what the inside of that engine looked like! Very cool!

Hey, Donut Really loved these two together, they complement each other very well Great job

These deep dive videos are AMAZING!!! Please make more!

Zach and Justin are an awesome team! Let's see more of them. Informative and fun!

This is the best kind of video from you guys! Super interesting stuff! That was one expensive crash. But it's a learning experience. I would have done the exact same thing if I was driving, only difference being that I'd be doing it at half the speed you guys are going lol 😂

this was a very captivating watch, thanks for this video

"I don't wanna leave an apple half eaten" proceeds to leave EJ only half disassembled

i love these tear downs so much

I totally saw that broken allen happening. It's a miracle when you don't have to drill at least one cam sprocket bolt during teardown. ½" drill bit for those curious lol.

Such a great video from all that engine carnage. Can’t wait for the others!

I love this format. Learning lots.

Could we get an up to speed episode of ken block? As a tribute

The last Hi/Lo series is the gift that just keeps on giving.

Thanks for this deepdive!!

Learnt a lot! Thanks!

These engine teardowns are my favorite

I appreciate yall doing this. I've seen videos saying yall don't know what yall doing. Keep up the great work. Number 1 car channel on RU-vid

Thanks for the quality content y'all! keep it up :)

Very good video, this is the type of video that donut media should be producing, you guys are great at teaching

Another well presented and produced episode by tradesmen who know their stuff. I really enjoy these videos and I hope they inspire others to become mechanics and mechanical tradesmen. Nice work lads.

So glad to see Zach back in the spotlight

This is the kind of content i love donut for!

I love it when donut does hands on and educational things like this

Finally more technical stuff than this list video

subaru community took a hit with these episodes . hopefully this redeems a little bit of our reputation

Great video. You guys opened up so far, wish you would have also opened the other side aswell

This reminded me of a story i had with my then brother in law who owned a 60's land cruiser (bj40). We tried to go up a very steep hill in 2nd gear (long), didn't make it and went down backwards. The engine kept running but was coffing and vibrating a lot. I quickly got to the key and turned the engine off. Toyota being Toyota, he restarted the engine and it didn't appear to have sustained any damage in the followibg months

Mr Subaru better take some of his comments back 😂

Justin is an awesome addition to the team now he seems more confident 🔥😊

Man I love your channel. So good and such varied content for us nerdy "want to knows".

Thank you for sharing this awesome upload, it is so good ✌

My dad always told me “If you start to spin, put both feet in” so things like this don’t happen

I know it’s a longshot, but could that gear shattering caused the opposite side of the motor to go out of timing and there is where the loud knocking is coming from? Did you guys pull the other side and look? I mean yes it could be coming from that side but that was really loud and I just thought they’d be more damage.

love these tear down so educational 👍

Sick new format 🤙

I really want to see what the other side looks like. If the belt got loose enough, that side still having both gears potentially moving should have really been unhappy. Also, i hate those plastic belt gears, I usually have to drill the bolt out with a 3/8 drill bit until the threads stretch and then they come right out and yes, i have the right tool

Thanks for doing this! It’s always great to see what went wrong!

Engine breakdown videos are where it's at. Keep doing this!

Please do more of this type video, where you dig into engines or any part of the car to be a teaching tool to us viewers. the game show and other things you have been trying have gotten very old. But whatever you do, keep doing it. You guys are great!!!

0:53, well its a boxer engine

Waking up to a Donut video! Better than a cup of coffee. Now to watch while my FA20 sits halfway built in my room

Justin is fast becoming my second-favorite Donut, after Nolan. Love you James! Thanks for this cool post mortem!!

Really great video 👍 A lot of people will learn. Do some tuning tutorials next 😉
