Thanks for posting this but even bigger thanks to Subaru for making every WRX owner to eventually have to do this. Can you recommend a shop in SoCal that does this?
I've heard on wrx to religiously do this every 30k interval. It does help a lot with efficiency so it can't hurt. It's just so damn expensive for a shop to do it
Great video. The only issue I have is your idea that you should wait 30 minutes to remove the one hose because of "pressure". Any pressure would be gone almost instantly once the engine shuts off. 30 minutes? The intake manifold is at -11 psi at idle.
Fuel pressure. It will be pressurized- the gentleman in the video was referring to the high pressure fuel connector. It is likely to spurt and can cause cornea damage to eyes, skin, and is poisonous. ☠️ In regards to the manifold vacuum or pressure- once the engine is off it is equal with atmospheric pressure. Waiting 30 minutes or pulling a fuel pump fuse and letting the engine turn over can burn remaining fuel and lower fuel line pressure but it is still a splash risk/chemical burn.
No, only needs to be done on FA engines because they're Direct Injection. STIs are Port Injection so they don't get the type of carbon buildup the WRXs get
this video fucking rocks thank you so much for posting this in depth, detailed, and very informative install video just saved my hydrolocked engine
That’s why we posted it to help others! Glad we could help 🤙🏼
Looks like im gonna pay a shop to do this for me. So many steps just to get to the main objective lol
Are the valve seats filthy as well? Cant clean those without teardown
Awesome vid! Thank you for the detailed steps! How do you know how tight to tighten all the bolts you take off? Is there a certain torque spec?
Great video! Really appreciate the step by step!
Is there any point in buying a dedicated walnut blaster, or will any sand blaster work well with walnut media?
If you've done this many times over, could you do the entire thing in one hour?
Great video.
Thanks!
Do I need to drain my coolant? Or clamp it anywhere?

It happens with every direct injection engine. It's why manufacturers started adding an injector back into the intake for each port.
What happens if the valve was not fully closed and walnut shells go past it?
Assume it's not good.
You don't happen to do this for others do you? I'm in montana and will drive to where ever you are located if so
I don’t do it personally but the shop in Florida called WRXperts Autoworks does you can call them to schedule an appointment.
@@JotaJotaSTI sweet its close to me!!
Is the crank pulley bolt 19mm? My 19mm doesn't fit
What’s the torque spec for these intake manifold bolts and the EGR bolts?
Did you mention around what time or mileage we should consider doing this at? like 100,000? or is this sooner?
45-50k

If by some miracle y’all still look at comments. I cannot get all of the walnuts out, idk how you do it please tell me if you have advice
can we not put the divider back?
For real! All that restriction for what
Good job JC...I wane that job on my car.sameone $$??

Do you need to walnut blast an sti ???

Thanks for reply
Where are you located? I need this for my wrx.
