CRANKWALKED? 7-bolt teardown 1080HD

Now this is a story all about how
My bearings got flipped-turned upside down
And I'd like to take a minute just sit right there
And tell you how I used to mix and burn my gas and my air.
In RVA suburbs born and raised
On the dragstrip is where I spent most of my days
Chillin out, maxin, relaxing all cool,
'n all shooting some BS outside with my tools
When a couple of guys who were up to no good
Started running races in my neighborhood
I heard one little knock and my rods got scared
And said "You put it in the garage until you figure out where..."
I Begged and pleaded that it not be that way,
But it didn't want to start and run another day.
I kissed it goodbye, because the motor punched its ticket
I got out my camera, said "I might as well kick it."
Crankwalk yo this is bad
Drinking metal shavings from an oil pan.
Is this what the rumor of crankwalk is like?
Hmm this won't be alright
But wait I heard knocking, grinding and all that
Is this the type of failure that should happen to this cool cat?
I don't think so, I'll see when I get there
I hope they're prepared for this video I share.
Well I pulled all the bolts and when I came out
There were chunks in my fluids in the pan and they drained out
I aint all depressed cause I seen this before.
I got my books and my wrench and we'll do it once more.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
If anything you could say that this bling is rare,
and when I saw what broke I stained my underwear.
I turned off the air compressor 'bout 7 or 8
And I yelled to crankcase "Yo holmes, smell ya later"
I looked at my internals they were finally there
To sit on my workbench and stink up the air.
Audio track by RojoDelChocolate.
Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag passes, a half dozen dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use.

[@flavourboss]

What a legend you are. Making all of these excellent quality videos for us scrubs to watch and learn. It amazes me just how well you are making them, and also your skills and tireless knowledge. KZbin's greatest DIY/educational/mechanical video making lord. Keep it up man, you have helped me understand a hell of a lot more than I previously had. And i'm 100% sure I am not the only one.

[@yoniajavon4923]

I used the principles shown in all his videos to rebuild my Saab engine thank you Jafro

[@BoostedCajun]

flavourboss absolutely correct! Because of Jafro, 4G63Swapped.com exists, and my love for the Mitsubishi brand. I too have learned they way of the DSM Yoda. Though my skills aren’t on his level, one day they will be. He needs to enter the contest on Power Nation so, this show can me syndicated! I watch and rewatch all these videos to sharpen my skills.

[@ricohegelund2789]

I´m a simple man , i see 59 likes and Instant hit thumbs up ;)

[@kielborde6802]

Love the bit about the two short bolts for the sump this video saved me potential disaster cheers mate

[@shawnjones7512]

Dude knows his shit!!! Ive talked to him before. Very nice guy.

[@QZPZ]

I have the feeling that he's done this more than once...

[@dsm985]

I have seen this video like 50 times now, I watch it while I think about the things I want to do to my motor. I SERIOUSLY LOVE YOU FOR MAKING THIS, It literally gets my heart racing everytime. Good choice on the music too, perfectly done! THANK YOU!

[@Jafromobile]

I just wanted to thank you for this heart-felt comment 11 years ago. I feel you, bro. It's a crime that back then when I had all my wits and local facilities at 100% I didn't have the funding nor this fancy new camera. It's only because of people like you that I made it. Thank YOU! Everyone else is closed now, but I made it! And hell yeah, RojoDelChocolate on point strong, too! I think this is his finest work! Maybe mine as well? I miss making 15 minute videos without voiceovers!

[@Jafromobile]

6 spoken words in this video. "Slap the nuts" and "cookies cookies cookies". Perfect! Half million views? Why I'm now writing and recording hour-long 11,000 word voiceovers is beyond me?

[@hooninglexus4537]

Videos like this are why i feel in love, your choice of music on top of them amazing impact sounds all just fall together, i love watching every vid more than once!

[@holdorf333]

I appreciate you taking your time to make/edit/upload all this material. I'm sure it's aggravating but I'm happy you take the time.

[@kcernest]

Great quality and detail. No real diagnosis but that's okay, not everyone is a pro mechanic. Just watching your tear down was great. Thanks for doing this.

[@Jafromobile]

The diagnoses got its very own video. ;) I had to take it apart first before I could look at it... thus, the music video. :D

[@fireballmx]

That is the greatest description in the history of youtube, well played sir.

[@jeffm26]

Dude this is by far the best, and clearest, video I've seen on you tube. I just ran into the same problem on my very expensive 2.1 de-stroked and I'm just sick...more pissed that anything however I gotta fix it. I think I might sample more of your vid's...

[@molsenice]

my mistake - I plopped this comment int eh channel section - it belongs here: Kinda wonder how big your grin is when you re-watch this - you have to know it is awesome and have a certain amount of pride - it just shows in your work, both in the garage and in the unique video editing style. Wicked nice job.

[@Jafromobile]

Tag. it's about time you're it. I've been it for 12 years? Geez!

[@shanelinehan9672]

subscribed, so fast. I'm addicted to watching all your videos.

[@assclone15]

awesome tear down i'm just lovin how the power tools went with the music

[@nicoh999]

Jafro- Thanks for taking the time and posting such great videos. I've watched this at least a half dozen times, and some of the silly stuff is hilarious. My Talon has been sitting in the garage for three years now, but after watching these videos (and finally having some extra cash), I think I'm ready to pull the motor and try to fix it myself (I have a spun bearing). Keep up the good work!

[@ephenj]

Bud, great vid, I love watching tear downs, and the beats playing really is good, mad props. Keep up the awesome vids.

[@ukspree]

I love your info section, way to add your own twist to the song I love it! And of course an awesome video as usual!

[@anthonywendt5834]

I just keep coming back to your channel for the tunes...

[@MD-ys5oe]

Had to like before watching! Simply because of the great creativity in the description

[@justsumday2010]

rofl I didn't read it untell i seen your comment haha lol awesome

[@BoostedCajun]

🎶Cookies Cookies COOKIES!!🎵 bing watching all your videos. Can’t wait for a new one brother!

[@jesseb7022]

Thank you very much for this video. I'm going to be tackling my first rebuild shortly on this same engine and being able to see this whole process gives me more confidence.

[@ourlife4545]

did you build it yet?

[@jesseb7022]

Just about to pull the engine starting tomorrow. Bought the eclipse non starting, with need of new panels basically everywhere. It's been a slow and steady progress. I just started the engine today after replacing my fuel pump and other various missing parts earlier this year. Car started instantly, ran smooth, but lots of grinding. (Mind you I've never been this in depth on a vehicle ever) Major reason I bought it was because buying the broken down GSX was cheap, and the parts car GST was cheap too. So far it's been a huge and fun learning adventure and I'm always excited to keep at it with my free time. Still not sure if it's crank walked or if the valve train is euchred from the crank pulley shearing off.

[@cy6039]

I'm in awe of your wisdom, and he raps too!

[@basshead4204]

OMG the description is gold!

[@paopao814]

man this is what gives me nightmares at times, literally. for a 7 bolt owner this would probably what hunts us. im not going to deny, it scares the hell outta me. ive read tons of articles of cw all over the internet however ive never seen it first hand so it gave me a peace of mind until i watched this vid :( ive been following your videos for referals of diy's and for the most part because you own, drive and race a 7 bolt.. On the contrary, i dont race my car but i do mountain passes for fun.

[@xxxxdarksidexxxx]

If I was young, and needed a first car, I'd buy this one just because your videos are that good. Wow! Subbing with notes telling me to watch many more. I'd love to stream this in the garage while I am working on my ride!

[@adamryanclark]

Another awesome classic this one is going into my favorite collection thumbs up two keep it up can't wait till its done again.merry christmas to you and your family and a happy new year.

[@BoostedCajun]

Cookies Cookies Cookieeeeeeeeeeeeeez! So glad you've gone through all the trouble to make all these videos. I watched them every single day. I always find something I've missed.

[@Jafromobile]

I know you do, brother... ;)

[@joedell71]

Ha you use your garage door for a spray paint tester just like I do.:D I can see the little spray spots on it at the very beginning of the video. I don't own one of these cars but I really like watching your videos because of the knowledge you have about these engines and cars and as a fellow gear head this is enjoyable to me.

[@MyBallsUrJaws]

lol epic description🔥🔥🔥

[@HamsterWheelGaming]

Description + ending were funny as shit. Nice work on the 7 bolt bro, keep that DSM alive!

[@chuckAWD]

Can't beat the factory gaskets and sealants for certain builds. I've used the OE composite HG and ARPs on most every build, OE sealants, and mitsubond!! Good for a leak free engine. Love the polished valve cover too. Sick.

[@jehsunbhe1379]

You are my IDOL!! Thanks for this awesome demo!!

[@paopao814]

@jafromobile I realy do admire your skills and tech knowhow. You make everything seem so simple and easy yet its not so much for me with very little knowledge.. Thank you for your comment it makes total sense.. il be following your 6bolt build too your the only one who really takes time to document and share with excellent detail. Mybe il be looking for extra blocks in the junk yards. any tips would be highly appreciated. i know there are alot of articles about it but i'd rather hear it from you

[@TheLeggera]

R.I.P those bearings holy shit..amazing quality videos wish j discovered your channel earlier !

[@Jafromobile]

Me too! What took you so long? :P

[@Jafromobile]

watch?v=6IumQqUa1bQ

[@tylerk6727]

***** Lmao

[@BoostedBeaverGarage]

@Jafromobile That was a very good and effective alternative. Instead of a pissing contest I got to read comments and a discription with some never before seen humor. Great job and 45 min is an accoplishment in itself. Look forward to the colt videos and I have to catch up on the CAPS one too. There is no way to like the discription twice so the video like will have to do. Keep us posted and hopefully I will see you in Richmond this summer. Robert

[@Magnus_Motorsports]

Another intriguing video. Although I've done this myself hundreds of times, I stayed to the end for the cookies!

[@iexploderacoons]

It's finally here!!!!!! You made my day!

[@BRKmaddox]

How have you not got more veiws?! Your videos are awesome

[@singlespeedman]

Great video, thanks for posting something another Wrench can enjoy and not something just for newbies.

[@Jafromobile]

Poke around... I've got a whole lot of that here! ;)

[@S3cK5hun8]

@Jafromobile this is a pretty helpful video. Im saying this because my friend is trying to convince me to swap a 4g63 in my mirage coupe. I may have to get an engine block without the cylinder head, but at least i can add some arp studs and a better head gasket on it. then maybe i can get a cylinder head with some crower stage 2 cams and some lighter pulleys and other things like that. keep up the inspiration Jafro.

[@35057]

@Jafromobile Great video dude! I've always heard of this "syndrome" but never got to see exactly what happens! Plus some of the high speed is funny.

[@35057]

lol! Never thought engine tear-down would be funny.. Good video! I get to see what actually happens in the bottom end.

[@joecualquiera]

Jafro, what a mastery!! Certainly Gemini has to be in many aspects in your natal chart !! Praised be the Lord who has blessed you with so many skills!!

[@Jafromobile]

Born at Midnight June 21st. Immediately between Cancer and Gemini. I'm mostly cancer by traits, though.

[@joecualquiera]

www.astrology-zodiac-signs.com/zodiac-calendar/june/21/ So if you say Gemini is not in the sun then it should be somewhere but what is clear to me is that it is there! Anyway a strong hand shake and my respect to you !! Greetings from Central America.

[@jfgoudy]

Great video. Your videos helped me replace my Talon Transmission. If/when my engine blows up, I'll know where to turn to as well :)

[@MartyMar815]

That was a great video description.

[@DEFCONPRODUCTIONSLLC]

A 6bolt turbo block with a 9k rpm spin balanced assembly should go back in your car....with a properly adjusted clutch you will never see crank walk again. Great vid bro, lots of memories :)

[@stevenstringham5624]

quick question is the bolt that holds the dipstick tube on an m10 x 1.25?

[@dreadnok320]

No i saw the metal flakes when u showed the oil pan. But it was just crazy to see how little carbon there was in the eng. Motor builds are missing from my Tool box of life. Its something i need to experience .I have dones lots of perf upgrades and more than a few swaps but no motor builds. I have started the hunt for another Legacy turbo project. I have a 06 STI motor and trans siting at my dads house along with lots of Perf parts . So i have the base. I need a good shell. Your VR4. GREAT FIND

[@mods245]

Jafro thanks for making these videos it helps me so much when I'm working on my Dsm It's like a video dictionary lol btw love the fresh prince remix made my day. Merry Christmas!

[@Jafromobile]

You left me a comment 12 years ago when I couldn't reply to anyone because I didn't agree to the terms of g+. I just wanted you to know I read your comment that day. Couldn't reply. I could upload, but I couldn't comment. It lasted 2 years. The digital oppression of 2012 era upon the dissenters. I remember it very well. You made me happy that day. Merry Christmas to you, too!

[@Frankjp555]

isnt the reason for 7 bolt crank walk the piston oil squirters? when they went to the 7 bolt they changed the way the valve worked for each squirter and they would get stuck open and since the oil for the squirters comes from the mains, thats why the crank walks, because the regular bearings dont need as much oil as the thrust bearing, and once the squirter valve cant close, the thrust bearing loses most of its oil out through the squirter. thats the best explanation Ive heard for it.

[@tim47012]

Your videos are interesting and inspiring. I like your attention to detail. I love the sound track. Did you make this or can it be purchased somewhere?

[@mapko15]

great video im thinking about buying an eclipse gst or better yet gsx what are some of the things i need to look out for in the motor?

[@jdmfreak92]

Dude, you're awesome thanks a ton!! It's just the balance shaft on the right hand side that runs a long with the timing belt.

[@Chaseponder]

@jafromobile is this a 95' 7 bolt? Did they have the split thrust bearings this year? I'm asking because I have a 98' 7 bolt

[@BoostedBeaverGarage]

I know I am late, but I love the Fresh Prince remix. Don't know what rainy day you started writting that one on but it turned out pretty nice. When we tore down my buddies 7 bolt his rod bearings looked the same and he had a ton of endplay. Happy building and I know that you will keep us posted. Robert

[@paopao814]

@jafromobile thanks for the detailed information. very useful. im leaning towards the oil jets vs oil squiters as i read much about the difference between the jdm evo blocks and usdm blocks (7bolt) is indeed a factor towards CW. however like you stated, any block can walk and there are many contributing factors to it not only limited on its design or bearing or material that the bearing/block is casted from. so hows the build coming up? good luck with it by the way and happy new year.

[@sivucit]

Thanks much for your advise. Last Question. When I do the junk yard technique presented by you in blue print video, i can find out end play using feeler gauge or digital gauge, if end play is within servicable limit, does that mean that Main bearing or Rod bearing is good, if hope not if thats the case is there a way to check with engine in car.

[@paopao814]

@jafromobile very informative thankyou. just to clarify tho, the sirius 2 4g63 didnt come up until the evo 4 correct? my frend has the an evo 2 which still has the same 4g63 that the 2g have. (just incase u missed a couple of my early post prior to the one that youve replied to)

[@maqueavelico1]

hey bro i got a question,im running royal purple 20W-50 ,do you recommend running my dsm with this oil or not,is a stock motor stock turbo...

[@RollingInBoost]

I have an evo 4 with 142000km .Still runs great, I was wondering is there any good way to test for crankwalk to check for the probability if my car will crankwalk? An answer will be appreciated. Thanks.

[@blksentra2]

Very informative man! I've got a 4G63 motor with about 1200 miles on it that is showing signs of "crankwalk" (Due to a machinist who didn't know what they were doing). I'm thinking about just getting a crate motor or something being that I just don't have the means (or a spouse with the patience) to do a weekend build like that.

[@dreadnok320]

I agree i use mobil 1 syn in all my cars. Its the best. It dose not take a expert to see that that motor looked clean for 10 years of Racing street and dyno use. I am a Suby Guy at hart have been for years. I have done the hon da thing but always come back to Subarus. I own a 97 M3 now. But have really wanted to buy another turbo car. I want to go back to my 1st love a 93 Subaru Legacy Turbo. But i cant find 1 anywhere. Great channel great info and the DSM guys are super lucky to have u

[@KeeleDesign]

I am running a 6 bolt in my 98, I Also have been running a buchur 20g at 32 psi on the stock composit gasket for 25,000 miles, and everything in the motor is upgraded. I've had no issues with it whatsoever. I personally wanted the comfort of knowing the liquids would be going where they belong.

[@sivucit]

hi, if my rod bearing or main bearing has too much clearnnce, can i just change bearing to get it corrected or i have to change crank as well.

[@waybous]

Knice clean tear down. It looked like someone blood poured glitter dow the dip stick tube. That 3rd bearing cylinder was so messed. I spun a rod bearing and I think it was due to crank walk. Just driving home one day stereo on as loud as I could get it and I push in the clutch f ar dies. I turn down the raido and let the clutch out and it sounded like a hammer k mmm ocking on a metal pot. Taking a turn at 50mph slung all the oil to the side of the pan and the inside tore spun and hit the rev limiter and I heard the engine strain and I relised what had happened.

[@sivucit]

hi is it possible to change main bearing and rod bearing with engine in car. Also is this possible to change thrust bearing. Pls advise.

[@DSMeclipsegst]

Jafro you should know this but i got my engine back from machine shop and the guy told me to make sure the tangs were right but i have no idea how to on Manly H beam rods is it the side with the numbers the side that has the tangs or is it the other side that has the tangs? And the tangs are supposed to face the intake side on a 4g63 also correct? (this is my first all out build so im a newb)

[@IkaraPentiki]

Yes we are. Jafro's videos are the bomb-diggity.

[@thatblackwrx]

Hey jafro! I stumbled upon this video, and had a question, I have a 99 eclipse gs 420a. The engine idles fine and everything seems fine, but once the car is at 3k rpms the engine knocks. But once I'm below that or idling. It doesn't knock. What would this be? And also it has a gas smell I haven't been able to figure out what's wrong. Any help would be appreciated...

[@sharky322]

hey jafro, whats up with that longblock you sent to machine shop ? is it ready to be build ?

[@Gmcoss]

i have problems w my engine on my GST turbo Mitsubishi eclipse 97 where can i take my car to get it fix? were i can thrust a mechanic

[@311GP]

I always hate asking for help on youtube but do you have any experence with building heads on dsm cause i think the person who built my head when they but the exhaust manifold studs back in they may have hit an oil passage cause oil comes out pretty freely from my studs im not sure how you would go bout fixing that? Any help would be a appreciated.

[@layton7430]

Is there a permanent fix for the evo 4 crank walk issue?

[@jdmfreak92]

I have balance shafts on my evo, I was replacing a ckp sensor and have to loosen the timing belt to thread the ckp sensor into position. It seems that the belt skipped a few teeth. I got the motor all lined up but how do you line the balance shaft up?! Please respond Jafro!!

[@QZPZ]

And don't feel bad about it. Pulled my motor when I bought my car and found cylinders 3 and 5 had spin rod bearings that looked almost exactly like yours

[@cskiller11229]

6BOLT TIMEEEEE!!! (: Great another video. Once again i learned something new!! I appreciate it!!!!!

[@Chaseponder]

@jafromobile so the 97 & 98s can walk even with the 3 piece thrust bearing?

[@morpheus232001]

Great vid! I'm a recent subscriber and really love you vids.

[@martinn61]

Jafro,wich are the signs of detonation? what do you see on engine head or valves when detonation happens?

[@Doubleotdsm]

Do you by any chance have a tutorial video on how to polish? I remember seeing your valve cover and it looked amazing I'm trying to get the same finish on my exhaust for my motorcycle .

[@Z1FU]

thanks a lot dude, Iam learning to do it by my self, and this vid is great, i can see everything step by step, I use a 6 bolt but i bellieve must be the same thing XD, thx again. adding to my favorites....

[@trillsouthernpimp]

i really like that intake alot. magnus does great work on their intake mani's. did you do your own egr valve work? or is that done by a manufacturer?

[@rogeronslow1498]

Man you work fast!

[@TomasRackAttack]

Did you measure the crank play? Just curious, mine might be on it's way out...

[@chuckAWD]

Awesome video!! Looks like this build didn't leak a bit of oil!!

[@no1aussiepaul]

enjoyed the video. make sure you get every spec of metal out of the oil galleries. Non indexed bearing scare the shit out of me. Im dreading this when I build my duratec 2.0

[@ChutneyInc.]

Wth! Thats some great editing!

[@ericebbaker]

this is VERY helpful. makes me want to buy this guys 1g just so i can take it apart.

[@hprider01]

how much those this run for would be better to buy a new engine i have a 01 civic ex 1.7 engine D17A2

[@charleysturbos7320]

Wow, That was very interesting and i learned alot so thanks. I so wish there were more mechanics like you. Seems most dont know crap or cost way to much for me. I'm so afraid my 2 g spyder will crankwalk like my other 2g did. Isn't there something people can do to help prevent this from happening. All the dsm guys with all these crazy things to make fast and help our cars and we can't come up with a solution for this crap ruining our engines? Thicker oil, thinner oil, oil additive? Anything?

[@trillsouthernpimp]

oh and another thing... what duration cam's are you running?

[@ParagonGarage]

I was having clutch issues for quite some time on my 6bolt pulled trans to change fork and pivot ball and then for shits and giggles tried to move flywheel back and forth and guess what it moved quite a bit🤬 so its been sitting for a year now because i lost interest in my 1G at that moment, thank goodness i have a 2G and S13 also. One day i will get to fix it

[@iconone5]

Oh wow, epic description!!

[@pray4war_1ss]

IM looking into buying a 7bolt gsx this weekend are they really bad motors or what i hear so many diff stories its unbelieveable any help would be great thanks

[@angelfall1]

este tio es una pasada, buen video

[@fckurvtc]

Jafro What size is that vise of yours? A Wilton 5.5"? If you don't mind me asking, where did you get it and about how much did you pay for it?

[@Kurisuchianu89]

Wouldnt a mechanical bolt stop be a more preferred method for the oil pickup tube rather than trusting a chemical one like loctice? Or maybe use both?

[@Liamautomechanic]

very good vid. a good bit of tinkering there to get the crank and rods out. was the engine starved of oil. that caused the shells to turn in the cap> or over revving.??

[@lathiat]

Can you link the exact video where you show/talk about this hidden bolt?

[@1TOPSPEEDPERFORMANCE]

Often thrust wear is because the clutch is pushed to far i always put a adustable stop on the pedal and adjust it so the clutch just frees enough, stops the clutch trying to push the crank out the front of the motor, ez and works good TurboPhil

[@5084204]

05:48 is it a crankshaft position sensor? (Plastic thing on two bolts and with three wires?)

[@oxisafox10]

Will you be using the cxr 20g on the 6 bolt?
