Love in depth rebuilds like this, please do more
We're planning on it!
In the process of rebuilding my 12 sti hatch and this video is a godsend! Thanks so much Grayson!
How's it going?
This was a well put together video. I watched every minute because there was a wealth of information and attention to detail that I thoroughly enjoyed.
Thank you Grayson,I love anything Subaru from OTL,as I am a Josh Bader customer BBR 500 2019 STI
Thats awesome!
Currently rebuilding my 2009 STI EJ257. Y'all are a god send!
Wow, this was amazing. Will be referencing this video soon after I pull mine!
Thank You, that was a interesting and detailed STI engine bebuild, i held my breath when you turned the key for the 1st time 👍 Au
This is fantastic. Although I just scheduled my shop visit for a new engine, I've definitely saved this for the project car!
will be watching this if i ever grenade my motor!!! appreciate the work you guys have done on my sti swapped hawkeye!
Thank you guys so much for this video. There are plenty out there on how to disassemble an ej, but almost none on how to reassemble .
Love this style of video! Keep doing these!
We will keep this in mind!!
Great refrence/build video. About to throw an engine together soon for my 04 STI. Awesome stuff.
Thank you guys so much for this!!!!!! You guys are amazing and have done so much for the Subaru community as a whole!
Thank you for your support!!!
Love the level of detail that you put into this video one of the best video I see on RUclips so far how to instal an subaru engine love the detail thanks alot
Thank you for making this, I'm going together with my first EJ25 assembly right now, and this is hugely helpful!
Good luck!
Best EJ assembly video I've ever seen. Saw it completely and learned a lot from it. Thanks a lot guys for what you're doing! 🙌👏👏👏💪💪💪
Thank you Grayson!
Glad you enjoyed it!
Sick build man. I'm actually in the middle of doing an 02Q swap on an 07K for a friend. Definitely cool to see some of the progress you've made with the car! I'm actually building my vr6 turbo right now and seeing videos like these motivates me to finish it!
not really a rebuild video as everything was already assembled more or less a video about installing heads on a short block, none the less still some useful info.
That blue point tool cart is sick👌
Awesome video my man. Thank you
Glad you liked it!
I feel like there should have been more appearances made by a torque wrench.
Glad I’m not the only one who thought this, as well as the lack of torque sequencing on the cam carriers and caps, improper rtv amounts and routes especially with the carriers and oil pump. Great video for a novice but the seasoned builders will see a lot of “NO-NO’s. Im honestly surprised as OTL has a good rep, figured they would follow the book 100% butttt…..
If it works for them and they have great results and no engine issues is their method wrong?
@@kaelll85I doubt this car is being driven like a real track / street car on a regular / daily driver basis.
Hey guys thanks for giving me the confidence I needed to pull and strip my own motor to the short block. Video and explanation is 9/10, alot of helpful tips and tricks. Cameraman needs to be fired for his lack of focus at key parts tho 😂😂 jokes. Both guys are awesome and thanks again for this phenomenal breakdown of the EJ257 🤙💪
Always wanted to make a stand that could lock into something to stop it moving when you got for those big torque numbers
Loved this one, any chance of a more in depth sti 6-speed rebuild video in the future?
Awesome 🔥
Bless you sir
Thanks. Many nice things here. How about a 600+hp shortblock in depth build next with clearance specs
I know on a Cummins when they do a hot retorque. Let’s see you do that on a Subaru motor. IV tried to do one and the bolts moved a little but the time and heat I lost taking the motor out was all basically piece of mind.
The laying on the floor under the car thing, i have done a million times!! hahah
This was great! Can you do this on an FA?
Hey man great in depth video. I’ve got a couple of questions to ask. I’ve got a 1997 jdm wrx sti Impreza. I’ve replaced the head gaskets already as I was lifting the heads. Running 2 bar of boost with a g25/660 turbo and all supporting mods including water/injection. When I replaced them I had the heads resurfaced, pressure and crack checked and everything was as it should. I used RCM head gaskets and RCM extreme 11mm head studs. It’s about 12 months since and I’m now lifting the heads again. Cat drives fine under normal driving conditions only when using full boost does it push coolant into the overflow. Car has never overheated. I noticed in your video when you torqued the studs you said on high horsepower engines you torque to 150 ft/lb. Is that with the same arp studs or with the bigger 14mm version?
My second question was about when you put the washers on you put lube on both sides but I watched a video with an arp representative who said to only lube the top side as it will cause a bearing affect and stretch the bolt? I’m hoping I can torque mine to a higher amount and alleviate this problem.
Much appreciated for any advice.
you just saved meeeeee!!!!!
WOOOOO

Hey man, how do you add a popn bang tune with carvery?
For some reason I’m watching this and I’m a pro Subaru builder haha. I use an impact gun on cam gear and crank pulley removal. Otherwise you can let me know how the fight goes and the struggle to use the tool when my dewalt mid rang impact takes them off with 0 negative side affects. Just use the damn torque wrench when you put them back on. Like every bolt on the Subaru engine should be torqued to spec or again strip all the valve cover bolts, and the one that I see stripped mornthan any other bolt is the oil pickup tube flange bolts that mount it to the block. That will kill your motor. I on every build drill out the oil pickup mounting threads and use a long cert so I know for sure that the oil pickup won’t fail. This is the #1 cause of failure, people buy the killer b pickup tube to fix the oiling then create a problem over tightening the 8mm bolts and pulling the threads out of the aluminum. To cover it with silicone and then take it to me with rod bearing failure and when I show them that they try to blame me. And I’m like I didn’t build your motor how is this my fault. Sorry but you can’t reuse the crank or any parts in that motor now. And the killer b pickup tube you just destroyed by sucking up so much bearing material and sending it to the cams and ruining them as well.
Do you need to replace the turbo with a spun bearing?
always check for oil leaks with your fleshlight after first startup.
How long do you let the RTV cure for? Seems like you just fire it up the same day. I'm thought I always had to let it sit for close to 24hrs before running fluids.
Can we get one for a fa20dit please 🙏🏼
I like the video very in depth. I wish you had better close up shots on some of the steps though. You describe it well but it's hard to see what exactly you're talking about.
Company23 makes a camlock tool for the TIC FU cam gear bolts. 59:00
OEM gasket vs a brand name aftermarket gasket ?
Question 1
You guys bought a new shortblock. If I need to rebuild my engine, the heads will be resurfaced but do I also need too resurface the shortblock the sides that connects the heads? I will keep it stock.
Question 2
And which part should I buy from third party and which oem I could order again.
I’ll admit I forgot that line but I got it in without taking the timing off nor the covers. It is possible
How much it cost 2015+ wrx engine block rebuild?
please note to not over torque the oil feed pipe from the oil filter that goes through the oil cooler, it can and will take part of your fresh new motor off with it if you ever need to take it out.
I don't like using silicone or rtv on valve covers, that stuff turns semi hard and if it falls off can jam passages etc... I use anaerobic sealants that only harden in areas that are sealed, the rest stays liquid and can easily melt away and get filtered out by the filter.
I also don't like using dielectric grease on coils anymore. I've had times with my own project cars or customers that the crappy spring on the coil may fail to make contact with the plug because of the dielectric coating which is not Conductive.
For the Grimm speed DP gasket I've had them leak, I don't have an oem turbo anymore but it's leaked on both oem and aftermarket FP turbo. They're MLS but I've always had to put on some high temp copper spray and let it dry, never had any leaks since.
The life eval on the floor comment... 😅 Yea we've all been there, especially while installing a DP and the external waste gate

If you drop the buckets and didn't know where they go, how do you figure it out?
You have to measure your valve lash
I just built my Ra block engine, part of my build i regapped top rings to .018-.020" bottom rings .024"...
Subaru had top ring .011-.013" top ring
And bottom ring .021
Big mistake not regapping a Ra block.
the 4 dislikes are jealous of your lovely equipment
You can see dislikes? I thought the Marxists got rid of that..
My toxic trait is watching this entire video thru and thru and thinking I can do it right away
No important order on torquing cam caps? The service manuals say otherwise.
took me 1 day to fully watch but i am confused on how you ran the car with no coolant, did you sub water if not doesnt that do damage to other parts like extreme fast temp increase
Hey thanks! You can start the car for 2-3 mins without coolant and you won’t damage anything. We do this just so if there happens to be an oil leak we can fix the problem without having to worry about if we’re going to have to open the cooling system. Just saves us a mess and wasted coolant!
I remember Cleetus making 1/4 mile passes without coolant and it was "okay". Cars don't need coolant until they reach like 200°F. The water pump can spin without fluid and it's unharmed.
love the out-most white-ness of the lab ^^
fyi on the RH exhaust cam bolt you hit 73.3 ft/lbs
Ya it turned red
Tuning tutorial when? 😋
Good video, but why isn't a torque wrench being used?
His hand and wrist are calibrated
M you say rebuild but the bottom end is already done, this is just the head assembly and aux
are you by chance in florida?
we are in des moines iowa
Just blew my engine at 32K, I only got to drive the car 8K of that. Think I'm going to try a build a bit earlier than I expected.
We offer 400/600 packages that could be just what you need!

I got 109k miles making 600whp and I pushed my wrx to 800hp a few times, should I get a rebuild ?
Only when it breaks! Run it until it doesnt anymore!!
@@OffTheLinePerformance big Bett, I feel a lost of power now so I might get a new motor
@@chasestoddard6984 awe man! We'd be more than happy to help! If you have any questions shoot us an email sales@offthelineperformance.com
Don’t do the crank shaft trick for that cam gears, not recommended
You used the oem head gaskets….why not something like cometic or felpro or whatever…why the oem ones?
I know that some people like oem gaskets for their open deck blocks
@@cheddardavis5818 okay but are they better than aftermarket? Because I know these are a real problem area
Depending on power level I’m not 100% sure there but I see a lot of people under the 500hp mark using oem especially with the fa20
The car made stock power, so no need for the upgrade! All of our big power builds get upgraded HG
I didn't realize subaru uses SOOOO much silicone everywhere instead of actual gaskets lol
You would be surprised on how many modern engines seem to use more gasket maker/sealant than actual gaskets.
You are NOT supposed to lube both sides of the head stud washers! Only the one facing the nut!
Not a rebuild... The short block was basically done... This is just the middle of the long block assembly/build.. Aka heads and on.
I do like the cam gear holder tool, but I have a 04 ej25 block w/out the variable timing on a ej20 head IIRC .
I'm truly confused on when putting a timing belt or chain on any engine rather it's a Subaru or Toyota, Chevy !!! And your not using any specialty tool the belt our chain accidentally slipps how would it kiss a piston and bend a valve?? When a valve that is fully opened will spring back to its seated position !!!! THE only way I can see any valve being bent is on a interference engine that's running and the belt breaks our jumps. Thanks PLMK?
Yes, as long as you don't rotate the crank, the valves won't kiss the pistons. When installing timing belt, the LH head needs valves opened to line up, and if you rotate the cams the wrong way, you can cause the intake and exhaust valves to collide.
i fell asleep how tf did i end up on a 2 hour long tutorial of building a car that i didn't even know existed
No one mentions batteries. Once they get a lot of charging cycles, that battery is wasted.
And new battery costs almost like a new EV car.
That's why, IMO, EVs depreciate faster.
wrong,
I love the video but you're bumming me out again we need to build a time machine just for parts never-ending bringing back musclecars
EJs are throw away items now
It’s pretty hilarious honestly you just said there’s no good Wave that you can do this because it’s messy so there’s no way you can put gloves on your hands. It’s just impossible thing. I guess some peoples hands just don’t have pores.
Shit Bait…..How can it be in-depth when you didn’t touch the bottom end.
90% of the people doing a motor replacement in their garage will be purchasing a block already assembled and refurbished heads.
@@Otl_grayson Bull Crap
That's quite a claim and I find it highly unlikely.
Even so then say "how to bolt heads on a Subaru engine that's been rebuilt" not....
"the MOST in-depth rebuild of a Subaru engine known to mankind.
Big difference from rebuilding an engine to bolting heads on an engine.
Typical "ShitBait"
The MOST in depth EJ25 rebuild tutorial EVER.......... yet you cant even install the head studs correctly right off the rip......
And how exactly did he install them incorrectly?
@@jack_brown7 if you ever built any engines with any studs you should know to tighten the studs by hand to not blow the threads out of the block, let alone covering every part with arp lube prior to torquing them will throw the torque specs off, I mean every box of arp bolts comes with instructions and tells you what not to do and what not to grease.
ARP specifically tells you too lube them, how are you going to try and tell someone who has built numerous 1K HP engines hes doing something wrong smh@heywoodjiblome2745
@@Anonymoose0913 you clearly never built any engines since you don’t know either, the studs should be finger tight to begin with to not put extra strain on the threads in the block, and the lube only goes on one side of the washer and on one side of the studs to get proper torque spec, not cover everything in arp lube and make up your own torque specs….. not trying to be that guy that pretends to know everything, but cmon don’t go out there putting out build videos when you can’t even follow the instructions on the head studs that literally literally come with a step by step instruction sheet in the box
@heywoodjiblome2745 Once again, this person has built multiple one thousand horsepower engines that are still healthy and running to this day - and have been for years. You are being exactly that guy that knows everything on the internet. I think the person who has an outstanding reputation for building these engines to varying power standards and has for years knows exactly what he's doing. Where as you appear to be someone just looking for something to critique.
i would stay away from that aos
