They need to bring this stuff back into high school, this guy or others could teach a lot to the younger generation
With current president in your country it seems like they wanna to abandon schools. Can't see them getting any better for teaching good skills that can make you money.
So true, but the younger generation is being taught to “throw away and replace” rather than “rebuild and recondition !”😢
Shop classes and machinery and good teachers are expensive and dangerous legal liability. Schools need 100 times more funding to do this. Our billionaire overlords much prefer uneducated dumbasses to well educated people. It is this way on purpose. Don't blame the youth, blame the rich.
All the factories in the area where I went to school donated stuff to the shop classes
Thanks for taking the time to record your work, Jim. There's a lot to learn from you. 👌
Clean up guy is a master !!! Hopefully, with DEI gone , American will go forward into an Era of quality and precision as we use to have !! American #1.
Bloody great work man. I had a WRX and an STI in Switzerland but a stroke 6 years ago left me driving an Automatic XV ! You have some really cool tools / toys there
Had this happen and done on my '13 WRX (spun bearing, new short block, heads redone) - great to see what goes into it. Keep up the awesome content!
I do hope that cleaning guy gets a raise, really enjoy this video (as always) :D
Appreciate it! 😎
I thought it was kind of cool to see you using an Indestro 1/2" drive ratchet. I got one of those in a socket set from my dad on my 16th birthday, 59 years ago. Probably one of the best ratchets ever made. I still use it.
Thanks for the video Jim. Great teaching video on these WRX heads. These motors were hard to work on. Nice job Jim.
Excellent work.
Coming from a Gunsmith here in Pa. I really enjoy your videos.. I hope you both have a great Sunday..
No negative comments against Jims shop
Is there typically? I’m kinda new here, so not sure. I also don’t know what people could say. Seems like he does great work and a nice clean shop!
I got one: They are too far from me.
Ill make a negative comment. Needs more real engine work. MM tractors and flathead V8's 😂
Awesome job!!! I bet the bad rod bearing was the front driver side cylinder. They caught it before it created a block window under the A/C compressor. Thanks!
those steel washers under the valve springs are very important on alloy heads.years ago i had a mazda bought in with a rattle in the top end.on removal of the valve cover i found the valve spring with the missing washer had wound it self into the cyl head like a thread tap.
A little piece of thin latex works good lay the keepers in the retainer and put it on the end of the valve spring then compress the valve with the latex laying on top of the keeper and it pushes the keepers right into place
I might have to try that. I wonder where I could find some thin latex?
@@JAMSIONLINE Truck stop bathrooms sell balloons.
@@JAMSIONLINEThe cleaning guy should be able to answer that and lead you in the right direction.
@@JAMSIONLINEJim you may have to sneak into your boys dresser drawer…wait… he’s got a new little ….. never mind😂
@@JAMSIONLINE
I'll just use a disposable glove.
I used to fight tools that picked up a bit of a magnetic charge, in the tool box with other magnetic tools, but for things like putting keepers back in, I started using a ground down chop stick, made from plastic, it can't pick up a charge, so things don't stick to them... I also use the same, when messing around in the valve bodies on the pre electronic automatic transmissions... I didn't have to worry about things moving on me, when I tucked them into place, when there was no magnetism around.
Just my 2 cents, thanks for your work, your different episodes, I have enjoyed watching, and picking up things I didn't know. Thank you!
I was thinking a brass rod type tool to avoid the magnetism issue. Plastic works as well, like you use.
You can also buy a magnetizer/demagnetizer so you can control the magnetism on your tools. Or if you just want to make sure there's absolutely zero magnetism, you can buy a degausser.
I've watched hundreds of JAMSI videos, if you told me that actual ketchup was the thing to use for lubrication, I'd believe it!
If you get assembly lube in larger amounts, using ketchup and mustard bottles like that make dispensing easier.
@@aricp9173 I understand, but the knowledge the cleaning guy has, I would take anything he says as gospel.
Engine rebuilds.
It's what makes a Subaru a Subaru
I like your workmanship. Very unusual for me to award a good compliment in this field of work, so great job. I always learn something new in this channel
This cleaning guy seems to really know what he’s talking about.
I know! Bless his heart. We need to get him a promotion.
On the last spring, you demonstrated the best method of de-jinxing: by predicting disaster audibly.
Sounds like someone was using that engine to it's maximum capability. It's amazing that they can get 300 HP out of these little 4 cylinder engines. Beautiful! They look brand new.
These guys are great i think clean up guy is sandbagging hes smart
oh I don't kno..... he seemed to cleanup those heads pretty well.. HoHo
I have slight fear of sounding sacrilegious……. but the Church of JAMSI delivered a great message today!
Jim, I gotta ask…..what’s up with the extra set of glasses on the SERDI?
Also….as it relates to this week’s SHORT video.. I’m impressed, not only are you America’s finest Automotive Machinist but you appear to be a classically trained ballerina! 😂
What's up with the extra set of glasses? Did you pay attention to me in the video? I said these are the smallest of valves and keepers that we work with. I can't see them. Haven't you noticed how the print in the newspaper is getting smaller? Kidding aside, thanks for watching.
@ , I get it Jim, we are close in age. I wear reading goggles too. I’m up to +300’s! Ain’t nothing wrong with my eyes, it’s my short arms causing my vision issues! I had an accident in 2011 causing me to change professions from the automotive/ racing/ manufacturing career. I must be an idiot, I chose to revert and use my ole Gunsmith School education from 1980. If you think those keepers are small, you ought to see what’s inside a firearm! I work on every brand and type made. I do NOT use anything magnetic. Magnetizing small parts make them impossible to handle with tweezers etc.
I had a 25 year career building roller bearing engines and transmissions.(Harley Davidson) I love the convenience of a magnet and use one for the very same use you did in your video. I would never use anything magnetic during assembly of internal engine or tranny rolling parts, particularly roller/needle bearings. In a worse case scenario, it can cause a needle bearing to skate, then flat spot. Just about every serviceable bearing in an old HD engine (up till early 2000’s) is a variable sized, individual caged roller bearing in a serviceable/sizable outer race. Every race has to be sized then the correct oversized individual needle bearing installed in a cage…check fit and reparation if necessary. I spent a career working with teeny tiny roller bearings which can only be identified with a micrometer. I get the eye thing.
Best wishes!
@@JAMSIONLINEyeh! Those shortening arms are a real bugger. I often wonder when they'll come out with extensions instead of messing with eyes that can see perfectly well! At six feet!
I'm 81 and counting.
@@JAMSIONLINE Gravity is also increasing,apart from that reminds me of the many valve jobs done in the shed last century , a booger when you misplace just one keeper.
You installing the valve seals reminded me of a story from back in the 80's. A machine shop did a VW rabbit cylinder head for me. I got it back together and the engine smoked like a freight train (no smoke prior). I told the machine shop I was gonna bring the head back to them so they could ck it out. They found they forgot to put on the valve stem seals. I had to fight like crazy to get them to give me another gasket set. The job went well. Weeks later, I went to pick up a set of 302 heads that got reconditioned. I looked closely inside the valve springs, they forgot the valve stem seals on those heads too.
Would be the last they would ever see of my custom.
And another job well done mate!
I use a little assembly grease on the valve keeper to hold them in place on the valve steam.
Another wonderful video ! Thanks for sharing !
In doing the placement of the valve keepers I’ve always put a little dab of assembly lube on the valve stem so when the keepers touch the correct spot they hold to the stem. But I’ve mainly been working on small engines.
If I ever have engine problems I'm taking it to these guys
Naturally every Colorado machine shop knows their way around EJ/FA heads... Great work as always!
Try a dab of assembly lube on the inside of the keepers to keep them from floating around. Great vid. Thanks for sharing!
Great, great video. They get better and better every single time.
I'm in! Look forward to more content! If I ever need my cylinder heads checked, this is who I'd trust.
Appreciate it!!!
@JAMSIONLINE you guys and South Main Auto are my only subscriptions. High-quality entertainment and DIY information.
@@JAMSIONLINE hey, tried to watch last week's members only video but it asked me to purchase a membership, am I doing something wrong?
Great job!
Nice clean job
Great Video Thanks guys
Very interesting and education video. I kept waiting for you to demagnetize the probe or switch to SS or pointed wooden stick.
What socket was that you were using on the studs? Never seen one of those before...
Like these: amzn.to/40TpqDS
Valve keeps ! I always used a small screwdriver and grease ! Works every time !
passion in motion
Superb, Graci.
Never expected any EJ content on this channel, but I am here for it.
It would be an FA engine on a WRX after 2015. But same for me, was a nice surprise.
Great Content, keep making this videos!
Excellent workmanship Jim
Dang. The Cleaning Guy is really coming up in the world.
Someone isn’t over is head on the heads 😊
2021 I overhauled the engine on my the new to me 1996 Audi A4 1.8T quattro. Only 114000 original kilometers on the clock, therefore was everything in normal shape. But all the exhaust valve guides were way outta spec. So new 8 exhaust guides, 8 new sodium filled exhaust valves, new valve seals, everything together, runs like a champ.
Awesome video guys. Hope to see a little bit more of the newer aluminum head/block stuff.
Hey, do you guys dont use a little plastic cap for installing the valve guide seals? Prevents the seal to get caught up in the keeper groove and eventually rip the sealing lip.
We do use a plastic protector on valves with sharp keeper grooves. The Subaru uses a bead style keeper and the groove in the valve has a nice radius that the seal glides right over without damaging it in any way. Good point!
It might take time for an update but the work you do has variables that can change the timeline
Yeah great job wish I was close enough to bring work to you.
Came for high quality machine shop entertainment, stayed for the cleaning guy's stories!
He has a lot of them!
I use aluminum tweezers for keepers and other small things that magnetized tools will not work well.
Like watching Bob Ross of machining! Love it!
Absolute Gold!!!
Almost 700,000 members, not bad for the cleaning crew...
I heard that shop vac motor wind down! Lol I had the same one for roughly 15 years. The blue and grey. It finally died and the black shop vac I replaced it with literally burnt up the motor in a couple months! The old one noise would come n go from new. Lol.
We have a momentary switch on the floor to operated it with your foot. Step the wrong place and away it goes..
Awesome job brother ❤👍
Excellent work.
Well done, great job 👍👍
Jim, the metric set of Allen keys I have, has a mgnetizer/ demagnetizer built into the plastic keeper. I have found on screwdrivers and picks it works very well to magnetism them and equally well to demand them. I don't know if you have one similar, but maybe your tool supply truck can help next time he stops by, or your local HF store just might have one hanging on a peg somewhere.
Thanks for an informative video.
Regards from Canada's banana belt. 🤞🇨🇦🍌🥋🇺🇦🕊🇺🇲🪓🏁👍
Thank you
Import content interesting....good stuff and thanks....🔧🔧👍
3:02 Whats going on there with that socket!?! I thought you were doing a jam nut but then you moved to the second and third ones and theres no nuts!
Aww you touched on it right at the end, whats it called!!!
It’s a special socket for removing and installing studs. He explains in the end.
@@vhrocks81 Whats it called/who makes it?
Like these: amzn.to/40TpqDS
@@JAMSIONLINE 👍Thx!
Sometimes, I use ketchup with a little mayo........and or mustard, with a squeez of lemon. Gunna try some horseradish soon........in addition to my special valve guide sauce. Thanx Mr. Shop cleaner guy!!!!
Yeah I remember my 90 Eagle Talon TSi. I spent a whole lot of time, and money on that car. It ended up being a low 10 second car by the time it was all said and done.
It would be nice if there was intake port water injection to clear the carbon and afford a slight boost on hard acceleration.
Water Injection is EASY to install yourself and will keep deposits low. I ran it on my Chevy small block turbo's back in the late '70's and they were clean as new inside after they blew up. :) A simple Hobbs pressure switch about 4 psi turning on the water pump then spray into the turbo inlet. Really helps keep the detonation down so the knock sensor won't retard the timing to do the same job.
That's a thing of beauty!
Looks great
This is for the cleaning guy. A neighbor had a 7020 AC that he did a bunch of work on the 301 and it dyno'd 180 hp!
Just a thought, would a pair of angled tweezers help with inserting those valve keepers maybe?
Really enjoy your videos by the way
I know the aggravation of a pick getting a little magnetic. I acquired a couple of stainless picks, they're not expensive, and a tool I'm familiar with. 👍
Those heads will last for the life of the car!!!
Given that it's a Subaru WRX, that's slightly over 100 miles!
However, it will not be the HEADS that kill it... Either head gaskets, rust, or wrapped around a pole.
Seeing as it's already done 60,000 miles, your evaluation of Subaru motors ain't worth a pinch of💩.
If Jim wore a cap, I'm sure it would worn with the bill forward because he knows if he coming or going. :)
Adding a 30 degree back cut on those intake valves while they are out would have been a very worth while performance enhancement.
Good Job
You guys in Colorado have any snow? I'm in Boise, and we have a couple 3 inches!
Nothing like the old days, though, when 6" or more would hang for days!
Maybe a 'demagnetizer' for your pick!
Now you can watch the Super Bowl!
What's snow? Only cold and more coming this week. No time for the Super Bowl. I'm taking advantage of a fairly nice day to work on our dyno room. We got the pad poured last week and I'm back filling today.
2 weeks ago we had a record tying snow fall in the New Orleans area. Didn't have the equipment to deal with 10 inches of snow.
Did I miss you cutting intake and exhaust port surfaces ? Do you not show that portion to reduce the video length? I love these videos. I take parts to a machinist and have no idea what is actually done. The price of machine work has gone up (like everything else). It would be so easy for a shop to cut corners and you won't know for months or even years if the job was done right. Filming your work this way would give me full confidence in your shop. Keep up the great work and pass these skills on to the next generation.
I'd love to support you. But, I haven't been able to get work for a few years. It's tough in SA.
I first saw a picture of a Subaru WRX in a 1998 issue of Sport Compact Car. I had seen some rally cars on a TV channel formerly known as Speedvision. I also enjoyed certain video games. I'd like to think I contributed something to getting rally cars sold in the USA.
54 👍 's up Jim's thank you for sharing 🤗
It seemed like the quality of JAMSI videos had been going down, with too much music and talking and light on actual technical rebuilding and machining content. This video is a great return to form, really rich with technical information and long uninterrupted shots of just watching these guys at work.
I was about to comment the same, these type of videos are way better than the overcomplicated 'new' ones.
I agree music is a lazy way to do videos. If I want music I’ll watch mtv
@@daleolson3506The 80s called they want you back.
I know! A free video that someone spent hours making should definitely fit my narrow, arbitrary standard! How dare they try to improve!
@@liamdillon2478 🎯🎯😅👍
Another year of watching y'all over the super whatever is on TV
Finest job
Were the springs checked to make sure they were in spec?
Really love the work you guys do! How can I know that my local automotive machine shop does level of detail and care?
wouldn't a tad bit of grease on keepers make them stick and the slight magnetic pick wouldn't give you grief?
At my age this give me a challenge.
I wish I could send you my block and heads for a complete machine service and overhaul! 🤤
I always thought those heads were throw aways. Do you rebuild 8 hp Briggs and Stratton engines?
Had a friend who used to call them a Briggs and Scrap Iron.
So many people pissed about the premieres.
It's a chance to interact and ask questions without going live.😂
People just have to whine about their free content. We’ve always done premiers because we enjoy the live chat aspect. It is what it is. Can’t make everyone happy.
@@JAMSIONLINE keep doing what you do and don’t worry about the haters
I was surprised that as a result of possible piston against head intersection you didn't have a bent valve or 2...
Wait, it's not actually ketchup ???? I'm shocked !
Could you guys show us how your cleaning machines work, I would be very interested to see. Thanks. 🏴
The basket spins and there's a water pipe with spray nozzles on the sides that sprays caustic liquid at pretty high pressure.
Think of it as a big dishwasher with lots of spray nozzles, very hot water that's caustic to break down carbon and grease.
@@Jonathan-hx6oy Thank you.
@@AIM54A Thank you.
Absolute Star,, ✨👍🌟👍✨
Like any aoutomotive shop... Tourett's Spoken Here!!!
Looks good to me Cleaning Guy...
😎🫡
My neighbor spun a main on his rebuild after using catchup on his rebuild.😢
50:51 why are you putting keepers on the near/far side? Why not left/right?
Did they not send the rockers and cams with those heads im pretty sure they have solid lifters and they would need shims to adjust the valve lash !
The Subaru EJ20 and EJ25 were solid cam bucket engines. Later, Subaru used the FA20DIT and it was a hydraulic lash adjuster engine.
I think the easiest thing to see is that the Subaru EJ engine is a timing belt engine, the Subaru FA engine is a timing chain engine.
If you have a soldering pistol it is really wasy to magnetize/demantetize tools. Takes just a second.
What detergent do you use in your spray wash cabinet?
What tool are you using the remove the exhaust manifold studs?
Looks like he’s using something like the Koken 4100A stud setter/remover that I use?
They use a set of rollers inside a cam ring to grip the stud. Works the same way as the one way/sprag clutch you find in automatic transmissions, but it grips in either direction of rotation.
No doubt other tool companies have something similar as well, but there happens to be a demo on here (YT) which demonstrates their use that you might be interested in
Would have been good to explain installed spring height/pressure and maybe the need for additional shims under the springs. I understand that for this application not necessary but just to show people that sometimes it is required. Also I use a dab of white lithium grease on keeper grooves to hold keepers in place during install. Again no disrespect, I love your content, but I really wouldn't spray my new seals with brake cleaner, some materials might not like that, just my humble opinion, again no disrespect intended❤. I'm also as old as the cleaning guy, so I been doing this awhie also😂
