awesome video and awesome job dude. definitely going to refer to this video when I clean my valves in July. thanks bro
Great vid! Can't wait to see when you test drive it and hopefully notice a difference.
Great tutorial! Keep the great videos coming!
This was much harder than it looks. The subibro tool definetly made the process much much cleaner. At 45k miles the walnut is not enough and you do need to poke down in there and get off the stuck on gunk. About 7 hours in (by myself, newish hobbyist) and about to reassemble.
Skill issue
its possible, or maybe your attention to detail needs to improve?@@keegantibbs1789
Great video. Process not as bad as I thought. Also makes me feel better that in IMO not much gunk after 40K, nothing compared to what I've seen on VWs and Audis.
It's Thursday my dudes!!!! Was waiting for Part 2, hell yea bro!
This was a great part 1 and part 2 watch. Thanks
Great video. Really nice teardown of the intake manifold. Need more of these. :-)
wow impressive nicely done !
Bro where are you located would love to come up to Seattle and do some runs man! Love the DIY stuff you post you are the best
I have a cadillac cts gdi 3.6 motor have a loud idle at startup and car rides fine while driving but at idle I have a horrible cabin vibration. I already replaced the motor mounts plugs and spark plugs replaced the plugs twice last year and this year. Not sure what to do next thinking walnut blasting but, cant find a shop to do this.
What's the background music? It sounds so great with the video!
Any idea where to get the adapter at a reasonable price? Any way to check the condition of the valves without total disassembly? thx
Can I use the same procedure for my Forester XT 2015...
where can I order a blaster wand like yours?
does it attach directly to the blaster gun from harbor freight?
When you were doing this job, did you notice the knock sensor locations?
Hey I have same car with 12,000 miles on it I do all 2 miles to work and back can any1 tell me if the old iltalin tune up works or helps with these cars. Should I drive mine hard does it help or hurt cuz I drive mine like an old man
Did u feel anything after? throttle response and such? I had mine done today but i cant feel difference. Starting to think if the guy actually blasted it or not...
where do you get the blasting wand?
LOL. You saved the before and after shots for the end for dramatic effect! I was about to cry foul after watching all that and no looks of the valves after blasting! Good stuff mayne! Still looks like a PITA and I don't know what use I would have for a media blaster and shells afterwards. What is the dealer cost for this maintenance?
Thanks man! A shop quoted me $800. It's really not that bad at all.
$800??? Ugh, guess I'm going to have to tackle this myself...how many miles did you have or is recommended again?
Did y’all replace the intake gaskets?
Is this the same procedure for the Forester XT?
how many miles did you have on your wrx when you had this done?
that's awesome looks like a winner man
I saw the blaster at harbor freight but the kit does not include the long extension tip . Where did you get it and does it mount directly to the harbor freight gun? The adapter??? Where did you get it from ? Looks like one can be made from a block of wood with center cut for hose!!! Will the plastic cover you used work with a impreza 2.0 f b 20 engine? I believe you have a f a 20 . Please let me know

I know clean valves improves flow but how would you clean the area where the valve touches the valve seat? That's another important area. I am currently trying to get an answer from Subaru about the excessive carbon build up.
Subaru makes a 3 part fluid engine cleaning kit specifically for their direct injected engines. Definitely would consult a professional on it though. Dealerships should have it available.
@11:22 .. do u need to reinstall the splitters into cylinder heads with TGV Deletes? Do they serve any purpose at that point? Thinking they'd just cause restriction, minor.. but still restriction.
I took them out.
FYI. Replace those rubber gaskets. They like to leak.
Wow super cheap compared to what dealers/shops charge. Got my mk6 gti done for 800
I didn't catch the part about using the phone to see the valves
whats that blue alloy part with the crown on it?
LastHumansGarage looks like a vacuum pump cover.
Is it necessary to blast the splitters as well? I know you guys showed it in this video as a demonstration of how the walnut media reacts to metal, but I wasn't sure if that's something I should do as well. Awesome video. Very helpful.
If you are putting them back in, I would blast them too. Most who switch to TGV deletes end up taking them out.
@@CarsWithJR Thank you. I ended up blasting them. Car is running so much better now!!
Thank you, from...(epic music) the future!
Where do i get the tool to attach the vacuum hose to? I dont recall any info on it
Nevermind, the info is in the first video description
If you already have the TGV's deleted you don't need to put those head separator plates back in. You'll actually see a power increase if you leave them out.
$800 for walnut blasting at shops?! Geez. I'm probably going to do this instead and save tons of money.
How many miles did you have when you did this?
He said 40k.
Most shops are ~$300
Is this necessary? I have a Subaru that has 190k sting running strong. Just the routine maintenance.
I believe it's more of a problem on FA engines, compared to EJ series.
Did you get the "wand" for the gun at harbor freight?
That’s part of the subie bros kit
Question...when you're finished, how do you ensure that there's no walnut media left on the inside of the valves? Or does it matter if there are small particles?
Since you have to ensure the valves are closed, you simply vacuum out the remaining shells. They're easy to spot.
My WRX Channel Thanks man. I may give this a go.
Great video, how many miles are on the car?
40k miles.
Jr i have a question bro. I know you don't have the car anymore, but do you think the valves being dirty would cause fine knock learn or some type of weird stuff with the car? I'm almost at 55k and everything else have been checked and cleaned or replaced and this is the last thing I haven't done. Just curious what you think would happen with the car if this was really dirty. Thanks in advance
Yes, built up debris can come loose and end up in your combustion chamber causing knock.
I did mine at 40k and protune was at 30k it was disgusting then and im overdue about to do it again. Had egr and aos since protune also btw. Still very much nessisary!!
Any way to completely avoid this? Does the and egr delete help?
Tgv and egr*
No, it only delays it. There is still not getting around the fact that vapors from the combustion chamber enter into the intake manifold.
Does AOS help prevent this?
I will help slow down the build up.
hopefully I only have to do this once.
abernathy0011 Nah it's like every 30k-40k, I have 24,000 miles on mine and it's not bad at all yet.
abernathy0011 My guess was with catch cans or an aos along with the Egr delete no carbon or oil should resurface
Or... EGR and TGV delete to prevent this yeah?
Ya it will slow it down but you won't able to pass the emission
happy i dont live in an area that does it :)
whats the PSI the air compresser is set at ?
You should use the spec that is called out on your media blaster we used somewhere around 90-100 on this.
thanks , my15wrx has just over 60,000 miles ... its time I do this ..
Gonna touch 80k on mine. Excited to do this along with Stage 1 stuff while I'm in there. Planning on a catch can system in addition to EGR delete at the same time. Hoping I'll only have to do this once or at most once every few years.
When you replaced the coolant you initially drained, did you just pour it back in the Radiator? Also, did you have to bleed the coolant, and if so how did you do it?
Both videos were great! Thanks for putting this out for us!
Sorry for the late comment. Did you bleed the coolant? I am halfway done cleaning them (everything is completely apart, tomorrow I blast) and I was thinking of just burping the coolant system for air.
Still a little confused on the vacuum process, and also would of loved to see the valves afterwards, wth.
15:02
Before and after pics!!
At the very end.
Fair enough. I got impatient lol
Yves Chavez there is a video of it at the end if you watch the video.
Thanks. Someone just pointed that out to me.
At 120k miles on my car there was a sticky carbon sludge that needed to be scraped off, do this sooner than 120k and it will be much easier. Lol
I'm late lol
