Good luck Hanna. My daughter middle name is Hanna and she helped me change the front clip on a 1992 s10 blazer.
Not sure why I'm here, I don't even own a subaru (and probably I never will), but I like how this guy works. I've watched some of his older vids and I like his 'modus operandi'.
Hanna it's been great having you back this summer. Your presence adds a lot to Eric's videos and you will be missed. I hope you enjoy your second year of college but work hard at it. As I told my daughters, the secret to college is to always go to class and never get behind. Please come back and help Eric when you are on break sometime. Best of luck to you!
'I love napa wires', 2 seconds later, 'Freaking napa' lol
I love that in this video Eric suggests Marie as Hannah's replacement, which we all know by now actually happens!
Wobble bar extensions have to be one of the best inventions, saves many skinned knuckles and much cursing!
Mystery aircraft is a weight-shift type ultralight.
On my 01 Legacy, I replaced the timing belt/water pump/pulleys, as well as serpentine belts, spark plugs & wires, and valve cover gaskets at 106K miles. Only have used synthetic oil in her since I started driving her at 24K miles. She runs like a champ and has never let me down.
First off, it's good to see a Subaru in the official SMA SubaruBay (tm).
Second, what's up with Hannah Eric? She used to be shy and you never saw or heard a peep out of her, then she went off to college for a year. Now she's chatty, competing with you for camera time, and giving you all sorts of backtalk. You better hope she doesn't come back next summer...she'll be running the place by then if she does! :D
College will do that to open you up. It changed me John's Hopkins four years then six more then two metropolitan hospital for my internship. Then the fun of paying all that money back while trying to to live and maybe eat sometime now I am sixty and wanting to work full time at my friends auto repair shop my true love. Almost forgot three and a half years at MIT when I thought I wanted to be an engineer but found I liked to work on cars so I end up a doctor general practitioner. How's that for a fun 26 years right out of high school. Would I change any of it no not one second.
Love it she is developing into a leader
True
College does strange things to people.
Hello from Port Dover, Ontario, Canada. Electrician by trade here in Ontario Canada at Stelco steel for almost 39 years. Your instructional auto videos are very well done. Thanks for your youtube videos.
Eric,
Another fantastic video. Hearing Hannah say 'click' as she tightens the air box clamp with a nut driver: priceless. You guys are the best! BTW that spark plug 'gap' was huge!
SMA#1
God bless

"Torque it to spec."
"Click"
🤣👍
One other interesting thing is the difference in wear on the plugs. This looks like a "waste spark" system where one coil fires two plugs. This leads to one plug having positive polarity and the wear occurs on the ground electrode, while the other plug in the circuit is negative polarity and wear occurs on the center electrode. This is why on each bank, one plug had the platinum chip remaining while the other did not.
Correct, NEVER use anti-seize on Subaru/NGK spark plugs.
Man I'm Amazed, I've been using a piece of hose for over 50 years to install Spark Plugs. All this time I coulda been using a neat "Special" Tool. Gonna Get Me one.
lol, so true, few more years and everyone will need a special tool to blow their noses, oh wait :)))
*hands you Kodak paper* it's basically just as much as it's worth now these days
It’s so simple. I’m ashamed I never thought of it.
I started doing that 1974.
@@jaedonhaskins9917 when I started doing it my dad looked at me as if I had shown him a pink elephant flying! My dad started working on vehicles in the thirties. He worked on everything from Jeeps tanks to cars two trucks and a few airplanes. Not to mention some classified crap. He's like who showed you that? And I said I saw that hose in there and it's hard to get to this one spark plugs that I tried it.
Those girls were having way to much fun!! Great video but they stole the show!!!
I did not know that trick of installing spark plugs back in I always use a socket you learn something new every day thanks
My second highest hope in life is to see Eric O. service a 98 Geo Metro 3 cyl, just to hear him say "with the big 1.0".
That's what she said.
Hello Mr O ! Please don't let Hannah quit! Hannah! You can't go! You know you would miss SMA, Mr. O and family and all your YT fans!! You were just beginning to become interactive on the videos!
Thanks for the video! Keep them coming!
Everyone moves on and up...disappointing, I know. Good luck to Hannah - maybe Eric can find another intern!
Ima fan Absolutely! Life moves on. I wish Hannah well!
Dont be a GOOF
Ages ago, I did a mini tune up on my (then) gf's 1971 LTD--basically replacing plugs and wires and distributor cap to get it to run decently enough to get it to a garage for other work and save a tow. I knew enough to exactly replace the wires one by one and plug them into the new cap in exactly the same spot as the old cap (my mechanical abilities were limited). However, when I finally went to mount the distributor cap, I found that Ford had polarity-notched the cap in such a way to make it go in only one way--despite the fact that it was 180-degree symmetric (in other words, the plug impulses came straight through the cap without any logic or re-routing). I can see notching the cap so that it could only go in one of two (or even 4) ways, but this was overdesign. So I carefully removed the plugs from the new cap and reconnected them to the old cap, then rotated the new cap, and then moved the wires from the old cap to the new one. Totally nuts. Also, on this car, the windshield wiper squirt nozzles came in "left" and "right." Why? No reason to not to have just one nozzle type. Doofus. There were other things about that car that were similarly dubious. And, of course, it had the infamous Ford steering gear box wander. I drove a 1961 Fairlane with about 6 inches of play in the wheel. The 71 LTD had about the same. My (by then) wife got a 76 LTD later with the same problem, and we briefly had an 84 Ford with the same issue. At a time when just about every other car manufacturer built cars that went where you pointed them, Ford STILL hadn't gotten the message. What rot.
Q: Does anyone know what year Ford FINALLY had steering that properly pointed the car? I'm curious.
Oh the joys of a Subaru tuneup with lots of room, lol. I cheated with 3/8 fuel hose to start the plugs. Love your real life struggles in the rust belt. Thanks from Oswego area sir
Free tip Friday on a Wednesday published on a Wednesday! Incredibly rare for this to happen. Awesome!
The ribs are indeed to increase isolation resistance to ground. The non-ribbed plugs actually have better isolation resistance so long as you have a good boot seal.
The problem with anti-seize is that it messes with the torque specs. If you have anti-seize lubricant, the clamp load of the plug is higher for a given torque. If you use anti-seize use the angular torque method instead of a torque wrench. However, the torque of a plug is key. Engine damage can occur if the plug is not tight enough since it affects the heat transfer.
ALWAYS replace the boots if you have tracking. If you get that it's most likely due to poor sealing between the boot and the plug. It's always a good idea to replace the boots when you replace the plugs.
I used to release motor craft boxes when I worked at NGK; the aviation thing is legal related. NGK doesn't want to have any legal implications associated with aviation.
you are correct in the ribs on the spark plug same as high tension insulator standoffs used by the utilities. it effectively increases the length a voltage leak would have to travel by going down the valleys and back out. there in lies the problem- the boot goes past this effectively eliminating it existance as an isulative property. added to that the rubber used is naturally white. in order to color it a product called carbon black is added which of course has carbon in it. although its amount is small once a wire arcs over as you stated it will continue to.
richard cranium Your cranium is chocked full of wisdom
A self deprecating handle indeed. Very good 😂
CLICK!!! , you taught her well EricO.
Click...torqued to factory specs....
Oh man did I ever learn about having to sacrifice a valve cover when doing a head gasket job. Eric O. is correct, just slice the valve cover all the way through the shoulder bolt (usually on the bolt closest to the firewall) and then the cover will come loose. It's a pain, but must be done. I'm glad Eric O mentioned that he's run into this before because I was thinking I screwed up and was one of those typical "UA-cam Mechanic" hacks.....well...I probably am. LOL
Mr. "O" you are correct in that the ribs on the insulator on the plugs is to increase the voltage potential required to discharge to ground.
great video, as always - and thank you for making it. you and Hannah are like peanut butter and jelly. like it when she gives you a little attitude. i know this isn't about head gaskets but i never understand the love for a car brand that always needs a head gasket job. you would think by now, ol' Suckaroo would have increased the mating surface area of the head and the cylinder but what the heck do i know? good luck Hannah! nothing better than being a nurse and helping those who need help.
Your the man, great way to learn every time with your vlogs I don't miss a video!
YOU are Numero Uno, Mr. Obrachta! I love your channel. You are an awesome mechanic and best of all a great human being.
I Always learn something even on a "simple" job. Thank you eric!
Yo Eric! On the topic of Subaru spark plug wires...My friend's 2009 Forester came in couple years ago in with an intermittent misfire on cyl#2. Yup you guessed it, carbon tracking! Being Russian and not having any parts in stock, I cleaned the porcelain on the wire wheel and sent him on his way. Did I mention he was driving to Montana the next day?
Anyways, his engine ran perfect to Montana and back. Never mind that his clutch grenaded but the engine ran perfect ahaha!
A few months later the misfire cropped up again. Plugs and wires right? Guess again...for the life of me couldn't get the #2 wire off the ignition coil tower. The tower was literally SPLIT in half from the green crusties!! He ran the car with that coil for a few days before the dealership got me a brand new expensive coil for that Lemon lol!
Some people love their cars!! Lemon or not? That's his baby....
I had a problem like that years ago before obd. Drove me nuts until I worked late and got home after dark and opened the hood and saw the arc from the wire on the coil. Just grabbed some dielectric grease and squeezed it into the wire connection. No more problem until I sold the car. Great work.
started watch about a month ago, well done. cant stop watching.
You got some catching up to do.
Indeed, please don’t ever change. There are very few mechanic who will take the time to just talk to us and give advice.
Eric, thanks for the tip on carbon tracking. Keep up the great tips.
that's spark plug reminds me of something I did to my neighbor's dirt bike they kept riding it through my mom yard and tearing up her yard so I went over one day when they were around and took a pencil and drew a line down the side of the spark plug it was about 3 weeks before they finally got it running again😎
The moment I saw that first spark plug come out; I knew it needed valve cover gaskets. Also; Subaru like the neon's use a waste spark system. Meaning when one cylinder fires, the exact opposite plug also fires. Subaru ignition is so easy though. To me v6's on up are a lot more complicated. Good video as usual Eric O.
I've heard that some in the 'engineering world' refer to those insulator ridges as 'voltage dams'. Cool videos, Thanks!
good luck to Hannah she has certainly grown an become a confident you woman wish her well for her future endeavours cheers Hannah x
This was the first video of a Subaru Sparkplug and wire change that I've ever seen. My Neighbor has the exact same car, same year same model. And his engine bay is toast since the car was originally purchased in Vermont. Those flat 4's(Boxster) engines are different than most anything else on the road today. Kinda tight to get those plug in and out. Those leaking valve cover seals would have caused me to freak out if i saw that much oil on those plugs. Great video.
Enjoyed the video. Wish Hannah the best. From mechanic to nurse, that's cool. 🏁🏁🏁
Best spark plug video ever
My nr 1 was as gone as the nr 2 plug. Oil on mine was not as bad as his. That extra long socket sure would have been nice to have for my nr 3 plug. Hi to Hannah.
The way Eric and Hannah go back and fourth jabbing each other just make SMA videos funny
Same problem here in Boston with the lower valve cover bolts... Nice video 👍
Excellent video I have a 2025 Subaru with 37,000 and a intermittent rough idle, I will check the plugs.
6:26 -- Yes, the "ribs" on the sparkplug lengthen the path to ground, thus reducing the current flow from the high-voltage point to ground. High-voltage terminals on power lines and in electrical substations also have such ribs, for the same reason.
My first one I used a small, 3/8” drive Universal adapter to remove and replace #4 plug. It was easier than I thought it’d be.
thanks for all your vlogs Eric and family and i love Subarus' :)) from the UK
Those NGK laser Platinum plugs don't create a spark. They shoot the air fuel mixture with lazers!
Great video Eric
I love free tip Friday on any day of the week. Lol Great video, wish I could have seen it on the scope.
HANNAH!!! Don't you dare quit! SMA won't be the same without you.
A piece of 3/8" fuel/vapor hose makes a quick & efficient spark plug installer/remover tool. Perfect for all those recessed plugs that we encounter every day.
Thxs again, Hannah the best too your Future... Keep them coming Eric thxs again...
I like when hannah helps great video Eric O @South Main Auto
Always great to see the girls getting their hands dirty and taking an interest in mechanics. Time time to get Marie on apprentice duties?
I always used a piece of rubber tubing about 6 inches long to get my spark plugs started back in the day.
Good to see Uncle Eric employing Hannah (and Marie) to fetch the odd tool etc. Keeps them of the street corners and out of the ice cream parlour. Think you could convert one of the bays into a set of 'bleachers' and charge an entrance fee. Glad to hear that Hannah is almost finished there and heading back to college although think everyone will be sad to see her go. Nice one Eric...Would be good to see the 'Sooby' back in for the gasket replacement too and maybe even head gaskets. Seem to remember Ivan did that very thing in a video series. Regards to Mrs 'O', The Rugrats and the Pooch!
Always fun watching Eric!! Thanks man!
I am a new subscriber and have been binge watching when I can. I see Hannah in some of the videos. Is she Erics daughter or an employee. You can tell she has a real mechanical aptitude. He has taught her well. I missed Mrs O in this video.
Ok thanks. I get a kick out of his little girl sitting at her computer in the office /kitchen. She reminds me of one of my Granddaughters at my sons shop.
I really liked step by step process.
Excellent video bomb Hanna!
Its great to hear you mention Briansmobile1 I watch all of his stuff too. I need to find another person like you two that does bodywork and ill be all set.
another free tip friday - don't take out the spark plug if tube is full of oil - love it
At 17:15 Eric O. says, "Power steering line is right in the way." In 1973, I ran a power press, to bend cold sheets of steel, for Oldsmobile. I made 360,000 (yes!) heavy metal brackets to bolt onto the engine block, and to hold the power steering pump. (UA-cam "Olds 350 Rocket" shows this at the twenty second mark.) This bracket blocked access to the #1 cylinder spark plug. In that era the GM supplied a "Maintenance Schedule" booklet with every Oldsmobile that recommended setting the spark-plug gap once-a-year!
Another great job like always A+
Awesome, more Subaru videos please!
Hear here!
☝🥳
A piece of garden hose also works as a spark plug installer.
Ivan would most likely cast his own replacement spark plug boots from materials found around the house on the stove!😬
🤣🤣🤣🤣🤣
Jeff Leach who the hell is Ivan. This seems like sketchy Haggard Garage stuff I want to watch.
Pinehollow diagnostics, at least I think that's how it's spelled.
:)) funny, perhaps use a bunch of condoms?, no wait is the lube conductive?
@@throttlebottle5906 We used to use condoms to replace the bellows on cuckoo clocks. Works great. Now it's latex gloves.
Awesome videos very informative. Please get your self a better light for you and us. Thank you
Eric, Hannah already makes a great scrub nurse for you, she doesn't need to go anywhere else. :)
Holy crap. That's what I call well-worn spark plugs.
Thanks for the tip on the NKG plug wires.
I've got a 99 Forester with 280K. Have videos of replacing head gaskets, center diff, rebuilt shifter linkage and bushings.
Back in the good old days, we used a spry bottle full of water, spray the wires, watch the spark, ohh the good old days
I did on this one haha that is why the plug was wet I pulled it out ;)
My spark plug installer is a piece of rubber hose I got from dalowes. It’s not far from danapa.
Tom Davis I believe you mean, danaper
Correct. Dang spell check should have picked that up.
NGK or Bosch Platinum plugs will last at least 100K. Good choice. Changing the plugs on a cold engine will avoid stipped threads and you won’t burn your self in the process.
thanks for the links for the tools....i was wondering about the spark plug socket set...sucks there is no 14mm
Only Dr O could make a Subaru tuneup “must see tv” lol
You're a lucky mechanic to have some ladies hanging around the shop =)
Hanna has a good eye but a bad interpretation of what a prop looks like...a beach ball. That was funny. Nice work, lots of tips so thanks again!
Remember Wyatt, if they put NGK's in your plane...DON'T FLY IT!!
Wait, does your plane even have plugs!?!
with the image they used, it does look like a beach-ball pattern from the end. I already knew it was a no "aircraft/aviation usage label"
I have to yank the battery on my 2009 Forester to access the plugs on the driver's side. First time I changed the plugs: 1.5 hours. I can do it in 40 minutes now. Two small extensions and a ratchet. It is a tight squeeze regardless of which tools you use.
The recommended spark plug change interval on those EJ25s is 30,000 miles, I do believe.
Best wrench around wish we had you here in Monticello Indiana.
great to see a maintenance video on a subaru for casual mechanics. Thanks how about a subaru boxer oil change.
I believe on that “hang glider” pic is a ultralight aircraft.
I have this problem on my pickup truck. After a heavy rain, it would chug and stumble when started in the morning but after it warms up, it runs fine. It also chugs and flashes a check engine warning light if I go through a puddle at high speeds until I rev it up a bit in Neutral. Been meaning to change the plugs and wires for the past year.
Best advice I have for ej25 valve cover gasket replacements, don’t even bother with a socket and ratchet. You barely have any room to work. Especially on the driver side. Just use an old fashioned wrench or a ratcheting wrench. And be sure to double check your tube seals when installing. It’s easy to put them on crooked or even slide them too far on the tube. Other than that, it’s a great engine to work on. Now I wanna buy my subie back.
Usually the problem with anit-sieze on spark plugs is that people go nuts with it and get some on the electrode. That can cause a missfire because it shorts through the anti-sieze instead of jumping the gap. It's best to put a light coating up near the crush washer or sealing cone on the plug. That way you get some lube where the threads will sit in the head but not near the electrode. Though, I think after a few years it doesn't matter much with all the heat the plugs go through.
Anti seize can also lead to over torquing. Look up NGK TB-0630111 to learn more.
Yep, antiseize will decrease the friction and allow you to overstretch the plug at the specified torque. If NGK says go dry, I go dry. They know what they're doing. Factory plugs don't have antiseize on them either.
right, most of them with a shiny "chromatic" looking metal, is usually special plated to not seize and should be put in dry. always look at the box/directions though of course.
that being said, I still anti-seize everything, old habit, as well having pulled out plugs that went 300K+ miles! they were rather sticky, center electrodes burnt to and into the porcelain and the ground arms burnt clear off to point at the shell and it still ran!
@@throttlebottle5906 We can change bad habits. No better time to start than now! Put the next plated set of plugs in dry like they should be. :) You already know it's the right thing to do.
haha, I have and then they got ran 220K and were SEIZED like mad, go figure!
it was all carbon intrusion into the thread space, where as with antiseize applied, it solidifies pretty fast yet stays soft enough for ease of removal, by keeping the carbon out as much as possible. ( plugs too loose/bad gasket can cause that also, never re-use "crush gasket" plugs ;) unless of course you change the gaskets....
shall I go on? only giving 26+ years experience and following what I was taught by folks that had 50+ years before that and more..
EDIT: then again, plugs were changed at 20 to 35K then, because they were miss-firing, carbon coated and electrode worn down ;)
IRL, all they did was modify things to cover up the symptoms and claim 100K high mileage etc... change them at 30K still or squeeze it to 50K MAX. you'll save yourself an advanced worn engine, wasting fuel, clogged/burnt catalytic converters. need I go on? just tired of the cruft being "spewn forth" by the up stream pocket padders
I own 2 h-type Subarus and my Rotator ratchet is handy for this. My Justys on the other hand. Pliers work just fine lol.
What a nice work environment. Two pretty young ladies to help out.
Thanks for the FREE tip! You and your 'helper' are awesome!
I predict a million followers in two more years.
Do you guys hate PayPal?
Say "please" to your young lady when asking for a tool or part. Just say'in.
Glad I watched this, as I like to DIY it makes me happy I bought a Mitsubishi :)
Great video, Hannah going to miss you life goes on I bet you will be back for a quick tune up good luck take care.
Had that happen on my corisa 4cyl ran great when dry. But when it rains miss spark like i miss my mom. Called all garages around me. Well we can get you in next year. Called my now garage lowders. Hey they said get it here before 9am you'll have it before you go to work. $40 ran great!
If you don't have a spark plug installer tool or an old boot you can use a piece of 3/8 hose, it's what I've always used.
Famous youtubers are always popular with the ladies!
Maybe ask Hannah to find her own replacement and train her/him with a list of 100 things to do and not do.
Watching from Texas great channel I was looking at you older videos new subscriber here
Hey look I get the comment section without signing out finding the video and logging back in.
Thanks for yet another informative video. I read that copper anti seize is recommended for spark plugs, and then only if the plug threads are not coated with a harder (chrome) metal. I'd like to get feedback on this because I don't live in a harsh climate so I don't need to use the stuff very much.
Awesome video! I’m amazed at what I learn from you! Thanks brother
***Btw get me a “mediano” size needle nose 😂
Mediano = médium
Medio = middle
I’m Not busting chops just having fun!
Good try Hannah! 👍🏻
