[@rpvilleneuve]

Jafro, I want to say THANK you for owning your mistake. Not to many folks would have done that. That is just awsome. So many folks are so quick to blame something or someone else. Sometimes you should look into the mirror before comming to a conclusion. Also, thanks for all the informational videos. You have taken my dsm knowledge up about 10 levels. That's sad in sad in a way since I have owned, driven, and worked on them for just shy of 10 years. Now all I need is your arsenal of fancy tools. Thanks for everything!

I think 48K miles on a build that put down as much power as your engine was is pretty good. Stuff happens. I've done it too. Most people can't do a better job so they can't talk trash. I have faith in your ability. I'm a Subaru guy and I just love your videos because you use tools that most people can afford and are not overly complicated. You prove that you don't need a laboratory to build a great power plant and car.

[@Jafromobile]

warusweims What you said has many truths. Unemployed military aircraft mechanics proved all of it in the late '40's salt flats. I look up to those who came before me for inspiration. Anything that has been engineered can be re-engineered. You get better at it when you break stuff. You and I have both been bitten by the same bug. There's no cure for it, but you can treat the symptoms. "Auto racing was invented 5 minutes after the second car was built" - Henry Ford

[@kainhall]

i blew up my first dirt bike rebuild 10 mins after i put it together..... i didnt have the right tools, and to get the nuts off the crank, i put wood under the piston skirt/on top of the crankcase....and made a TINY crack heard.....SNAP RATTLE RATTLE RATTLE..... and shut if off.....(been working on cars from 6 years old....seriously) piece of piston skirt ended up in the combustion chamber.... but didnt take out the ports! fucking winning! lol 2nd rebuild has 3000 miles on it....and i need a new clutch (i ride that 100cc like a 1000cc), so ill probably check out the top end soon lol on the...sorta the flip side...i guess my dads got a 1997 buick lesaber with the buick designed 3.8L v6.....250,000 miles, still running the gaskets known the fail.... kinda gotta see how far it can go now..... the tires have almost come off the thing.....(ball joints, struts, sway bar links).....trans went out at 200k (just lost OD and still made it home) BUT. THE. MOTOR. WILL. NOT. STOP. and it runs great....

[@conflagrationTuesday]

I understand almost nothing about what you are talking about: but it is interesting and relaxing to hear to talk about whatever it is! Thanks for sharing :)

[@ScrubyMcBubble]

My bellhousing bolt was missing too!! i had bought the car with a blown clutch and replaced it. May have never been there or maybe i misplaced it but its definitely on me for not knowing it was missing on reassembly. 7 years later you're still saving DSM's with this video!! Your videos have been a life saver so far trying to understand my car as the previous owner has 6bolt swapped it. It was a long forgotten project ive had for 9 years that i have neglected after the water pump failed. The pandemic has given me time for self isolating hobbies again and ive been steadily fixing the rust and got the waterpump, belts, and pulleys replaced. Now it turns out i need a gasket due to overheating when the pump went. Got a small leak on 1st cyl into the coolant (leakdown test proved this). I notice it already has an MLS gasket so im hoping the block is still flat and smooth because i dont have much time or space to be pulling the block to get the RA right for a new MLS gasket. Anyways thanks for the videos, ive been binging the channel like netflix haha

[@J0cK3rFr3aK]

You are doing your videos in a very analytical and detailed way, I am not even involved with mechanics, heck, I don't even have a licence but I still watch your videos because they are very informative and you explain the relationship between cause and effect very good, thank you for your videos.

[@ferrumignis]

In an oil filter the bypass valve and the anti-drain valve are two separate things. The anti-drain valve is usually just a circular rubber 'washer' that's located at the mounting end of the oil filter, and covers the oil inlet holes. This effectively forms a one-way valve that prevents oil draining back when the engine is stopped, which is a problem on some (but not all) engines.

[@BayAreaMCs]

Had to take a second to say thank you man. Havent found many other videos that explain the right information im looking for, or take 20 mins to get to the point. This is clear, in-depth, and to the point. Your older videos helped me rebuild the transmission on my ford ranger and now again with my honda. Keep up the good work brother, you got my SUB!

[@Wondering_Wobble]

I have to say every single one of you're videos has expanded my knowledge. You are very thorough in each video and bring to light any and all misconcepted info regarding what it is you are doing. I enjoy and look forward to all future videos and I hope to be a DSM'R for a long time to come. And with you're videos to help guide thee to have a properly built DSM!

[@autofixation]

I don't even own a DSM engine or car, but I still found this to be very informative! There are a lot of things that you pointed out that can be applied to any car. I learned quite a bit, even thought that may have not been your intention. Keep it up.

[@Jafromobile]

autofixation No actually, that was exactly my intention! ;) Remember from which community you learned it. I was raised on classic and collectible Fords, but it was the DSM crew who actually taught me anything about cars. Sort of why I stick to it. Theres so much you can do with 'em. Much more affordable performance than a Judge, Shelby or Yenko. Plus it's more fun to me to be responsible for that performance than having to keep someone else's dream alive. There's at least a little bit of that in all of us.

[@kennethcohagen9037]

No 3 Rod journal looks like a no7 journal on a 350 Chevy when the soft cams they used in the 80's wore flat. In those cases the no 7 cam lobes wore out completely, sending shrapnel through the engine. No 7 Rod journal gets wiped in the process and you see a lot of metal from the Rod bearing imbedded in the crank. Glad you found the cause of your failure. I would have guessed wrong due to experience rebuilding so many chevys back in the day.

[@strykerhorse]

This exact method of failure occurred on my 6-bolt...the "crank walk bolt" fell out and then the engine started loosening the others+the starter bolts. I caught it after replacing the clutch and it's shifted like butter since. Thanks for posting this...hopefully it saves a few engines (and broken dreams).

[@gnaloin]

Nice video, great narration and good reasoning. This is very educational. I like it when people challenge generally accepted "because it says so in the book/internet/whatever" knowledge and find out stuff by themselves.

[@RemedyTalon]

I learned....so much. Thankyou. I'm gonna go check for my hidden bolt

[@thaiexodus2916]

This video helped explain what went wrong with my engine. Blown oil line, #3 cylinder raped, and rebuilt the engine. But the thrust bearing surface of the crank was trashed and went un-noticed. I had no clue why the engine ran rough and vibrated. Was ready to have the flywheel turned and balanced when I saw this video. Checked the crank shaft end play: 50 thousandths. Crank was bent like a pretzel, block bearing surface shot as well. Uncontrolled torque thrust. A boat anchor in the form of an engine.

[@DJDevon3]

This is what makes you a good videograher. You're just as willing to show the mistakes as the triumphs. Live and learn. I do it all the time. Just last month I busted up a brand new radiator during the install. Man enough to show what I did and yeah I'll never make that mistake again. Sucks learning things the hard way but you're much better for it.

[@crazyDIYguy]

Your videos are the best, if I see your channel I usually click the video, regardless of whether it's something specific I'm working on or need to know. There's always a plethora of good useful information that can be applied to a wide range of things. Gracias amigo 😎👍💯

[@davidpotter3777]

This was like a Sherlock Holmes Watson thing you must sleep better at night having figured this out and great explanation of the forces applied at the end I can't stand a bad clutch God bless you and your family

[@ZombieSixShot]

When my TOB went out i discovered that hidden bolt missing, im so thankfull i have a good bolt in there now because if my car suffered the same fate as yours i couldnt afford to put her back together right now. Jafro, thank you for your videos i love them and have learned so much. Please keep it up!

[@Kraals]

Great failure analysis. I suspect 99% of this type failure are misdiagnosed.

[@revolutionzerox]

once again I've learned something. I wouldnt have thought about un-even load with missing bellhousing bolts. makes perfect sense and is good to keep in mind, I look forward to seeing more vids and your gsx back on the road. keep up the good work

[@bitcoredotorg]

Very informative video. Thank you for creating and posting this! Your comments and method of explanation whilst actually showing the steps of dis-assembly/re-assembly without being boring is great - I look forward to more videos!

[@nickc2052]

This guy is so on point. Everything he explains is exactly what went wrong on my 3000gt vr4.

[@ChaseTruCutLawn]

Information overload, thanks for the great video.

[@natenut]

i am checking this on my car tomorrow morning! i'm pretty sure the bolt is not there. Thanks for your priceless videos and advice!!

[@blksentra2]

Taking the transmission off this weekend, very anxious to see what's going on in there armed with this new information. Thanks!

[@AATopFuel]

Jafro, good job! I don't build little engines like these, but it is fun to watch you do stuff. At least you are man enough to know that you screwed up and you probably saved a couple of people in the process. I build Mopar's and we have a one similar to that and that would be an oil galley plug in back that we all miss when new at it. Like your engine it is hidden in the back of the engine and if you get in a hurry and place the outer plug in not thinking or seeing that there is a second one behind it, well I bet you that you can imagine what would happen. Thanks again, have fun. JBL

[@EDIAutoChannel]

Thanks so much Jafro, For that missing bolt ! Right when i watched this video i went out of my house jacked up my car and made sure that this bolt was in there ! Even if its -19 out side !

[@blindabinda1234]

KeepinIT_StockG35 was it in there?

[@myesantos5824]

Thank you very much for your videos! I've really learned tons from these, and I'm gonna start my own rebuild on my engine for the first time.

[@1InfinityShade]

But it did teach me. Thanks for the video. My buddy wants me to get into DSMs because he has two and thinks i would enjoy a change of platform. I asked him about the differences in 6 and 7 bolts when he brought it up but this was more visually educational.

[@paulhenry8560]

Thanks for taking the time to do these videos on the misdiagnosed crank walk!! 😉

[@limowreck2612]

Outstanding video, and I love that big blue Wilton!

[@johnestey9041]

excellent video, bravo. as Honda owner and a caterpillar technician and have been thru several failure analysis classes, blew and built 100's of engines and my conclusion is this engine was oil starved at some point whether the engine oil level wasn't adjusted properly or the engine was raped on with low oil temperatures, since 3&4 are the furthest away from the pump they were the last to get lubricated. bending a crankshaft from shock load isn't likely IMO, that don't really don't explain why

[@FeeeshEP3]

'maybe I'll build another 7 bolt some day soon' --- clean room ready! really looking forward to this :)

[@ChristmasCrustacean1]

6 bolt, 8 years in the making coming tho but I would really like to see jafro rebuild this engine some day

[@Ryan_1997]

wow I noticed THAT wen I purchased my 3rd dsm. my.gst didn't. have that bolt wen. I did inspection,... thank God. I put one in years ago. but very great information jafro. had I not put a bolt into that part of the transmission. would of had this problem commonly as others. like we all say" thank u so much! Im glad I learned something new!!!

[@jth1699]

Interesting - another thing that will cause that type of failure is a failed harmonic balancer...

[@mitsuturbo]

I've encountered this issue MANY times. Rather than crankwalk, i've seen it all too often result in cracked and broken bellhousings. Two GVR4's came into my possession over the years which each had this "special bolt" as i call it, missing. They both had cracked bellhousings. A word to the wise, if any of you reading this ever have someone ELSE work on your car, make SURE they put this bolt back in! The factory one has a 12mm head, and has a #10 on it.

[@JPilot2]

Dear Jafro, I found the 7-Bolt Shortblock Failure video, with your Full Diagnosis to be extremely useful, and very valuable. Thank you kindly! Cheers! :-)

[@johndelta00]

The drain back valve you referred to is a separate valve that most oil filters are equipped with and is essentially a check valve made of rubber that blocks oil from draining back through the INLET side of the filter(outer holes). Also, not to be too picky but not ALL oil filters are equipped with a by pass valve either, the by pass valve on GM engines is integral to the oil filter adapter therefore filters made for GM engines are not equipped with one. Awesome video's keep up the good work.

[@sergMpowered]

As I am not into DSM's anymore, I did loose a 93 7 bolt engine to this very same thing. It even broke a ear of the transmission and subsequently cracked the crank do to the torsional twisting of the crank.

[@ODMIJ084]

Wow Jafro another awsome video. I can honestly say that I am absolutely interested in the build now, and can't wait for it. Keep those videos coming.

[@lucascournoyer11]

dont worry i still got faith in your skills thank you for your very good vidéo.very helpfull and welldone.wish i have your habilities,maybe after your 213 vidéo.thanks again.

[@tomrodgers1596]

Thoughtful, insightful, informative - good postmortem!

[@talontsi92]

Glad to see that I am not the only DSM'er to have had someone else's idiocy cost them a part because of this bolt. Mine cost me the entire transmission, as it broke the bellhousing. Luckily the engine never suffered failure due to this.

[@FrostD3mon]

I must admit man, AWESOME video!! Subscribed!

[@jesterkid99]

You share alot of great information I can't remember how many times I have learned from you videos on how I should work on my engine I am currently working on. Keep up the great work and useful info coming :)

[@SkwerIe]

This video was published the same week I was pulling the transmission out of a neglected 1G I had just bought. I just now saw this, weeks after I sorted the problem out. I wish I had seen this sooner. :D That bolt was broken off in the transmission on the car I bought, and several other bolts were missing. The previous owner had driven it that way, until the clutch gave out. This video will haunt me until I decide to pull the engine and rebuild it...

[@sethat8e]

Nice carnage, its also nice for someone to talk the honest and sometimes demeaning truth.

[@MainyMitsu]

Great video Jafro! I'm going to verify all transmission bolts are in the correct place as well as there torque as soon as I get home!

[@jb2zero0six5]

I meant on my jenk motor Lol. Though, that was last Saturday, very well could been #3! Hell, I don't know what clutch is in the car yet. I'm also directly following the alternator rewire and battery relocation video while everything is out. I love wiring, and your videos are of course gold! Starting over someone's half-assed project is always fun!

[@802Garage]

Doubtful you'll see this, but I know you'll probably reply if you do. Have you or has anyone considered tapping another bolt hole in the transmission or engine along with a matching hole to add even more clamping force? Another bolt somewhere below the center line of the input shaft as you demonstrated seems like it would be useful.

[@Jafromobile]

There are already two matching doweled holes on both of the bottom corner of the block. It would be a messy endeavor to add another one as the aluminum bell housing has risen castings along all of the transmission bolts. It tapers thinner where there isn't a bolt. So while you could add one, unless you did something to build up or strengthen it, you may have added a great place for the bell housing to crack. One of those doweled holes nearby is the one the crankwalk bolt goes into. If it's there and torqued properly, then it solves the problem. So the added hole should be unnecessary.

[@802Garage]

Awesome. Thanks so much for answering. My concerns were about cracking plus difficulty with placement as well. I appreciate your assessment of it being unnecessary. Keep being awesome. :)

[@02studios]

thanks for the heads up mate, am just about to build a 7-bolt.... just missing a crank sensor..

[@dtiydr]

Im not into cars and I don't even have one but this was interesting to watch. The stronger the engine the more delicate it could be but as long as everything as it should be there is no problems but even an small insignificant thing can destroy but when you know why the thing had to be there then you understand.

[@jerryware2500]

hey jafro I put that hidden bolt on and put everything back to gather and my car shifts into the gear right I took it out for a drive yesterday thanks man for helping me you made my day I even looked at your other video how to adjust the clutch I did that too everything good thanks great videos

[@JupiterDrifterX]

OMG, my mind is blown! (12:07) Back in 2004 I had a 1992 Talon AWD TSI on 25 psi of boost. I was never sure why the engine had failed the way it did. The transmission block bolts backed out resulting in a broken clutch (act 2600), engine block and cracked Shep racing trans.

[@joshua43214]

I used to work in a Saab specialty shop. Saab oil filters come with a plastic cover to prevent debris from getting into them. You had to be careful when you puller the cover off because sometimes the little nipple that went into the thread would break off and stay in the filter. We had an underpaid guy who worked for us that did all our oil changes, tire, etc and he changed the oil on a car and accidently left a tiny bit of plastic in the filter that got sucked up and lodged in the oil port to the head. It passed just enough oil that the car ran, but the lifters would start to clatter a bit when it got hot and he ran it hard. About 2 months after he got his oil changed, the engine underwent catastrophic failure. When I took the engine apart to determine the cause, it looked almost exactly like you engine looked, major damage at one critical point, and minor damage from all the metal in the oil. Your point about the missing bolt and the clutch is spot on. You will get all sorts of major issues from that bolt being missing. I seriously doubt that was the cause of your problem though. I suspect that something blocked that oil port.

[@Jafromobile]

Thank you for your detailed comparison. I fully agree with you. I did have oiling problems in this engine. But it would have taken a LOT longer for the bearings to spin if I didn't have a mis-aligned clutch hammering and pounding on those bearings prior to the oil starvation. That clutch bolt is responsible for more cases of crankwalk than DSM owners are willing to admit. Like the clutch problem, the oiling problem was my fault because I'm my own mechanic. That's why I'm here owning my mistakes. ;)

[@joshua43214]

That bolt is the cause of a lot of problems. I have seen destroyed clutches, damaged crank flanges, broken starter holes, and many other problems like that on all makes that have that basic system, so it is not just your car but a front wheel design flaw that is not easily remedied. If it was the primary cause though, you would have had more damage to the thrust bearing surface (it did not look very bad to me, and .014 is not enough endplay to obstruct the oil ports), and the rear bearing would have been in worse shape. Mistakes happen. Even the best techs let a piece of junk fall in an engine from time to time. I once dropped an M&M a Saab fill tube. This was back when Saab engines used the transmission as an oil pan. I had to pull the engine and separate the units to retrieve my candy. My boss was pissed lol.

[@Jafromobile]

joshua43214 Ah yes. The old-skool Saab 900. Joy of joys. You had to pull the engine for just about every service job on those things. It's a shame that M&M's aren't magnetic.

[@DENicholsAutoBravado]

***** Lol, yes, it's just too bad. The M&M isn't magnetic, but it is attractive. MMMM. Candy. :)

[@AlchemistLair]

Excellent video!! Tough lesson but I love the way you analyzed it out!!

[@figifister]

You the man. Thanks for the explanation. Props on being humble.

[@paopao814]

Hey jafro great informative video. Bitter sweet experience for me because i was praying that once i crawl underneath my car i would find this bolt on that hole however it was missing. I hope its not too late. Ive driven my car for 8k miles for two years now (133k on odo atm) since i bought it. Hard acceleration here and there. I hope its not too late now that i have that bolt in there. Car is stock and its my dd.

[@kybluesnbullets100]

I know this is an old video but I will try my luck anyway . As for putting all the bolts back in the bell housing MAKE SURE you put back on all stamp steel brackets that go from the bottom bell housing to the block this is to support the bottom half of the trans mission and gear box .

[@fuzzywoz]

Wonderful video, number 6 bearing on a blazer is the worst of mine.

[@zx8401ztv]

Smashing diagnosis mate :-) No one's perfect and the world would be very very boring if we all were perfect :-) Dont stress if you make mistakes, we all make them, some people more than others lol, but your honest about yours :-) Your wisdom is still intact master yoda :-)

[@sivucit]

Thanks so much. Manufacturer recommendation is 5W-30. I am thinking of going with 0w-40. By having zero weight, I can have my oil flow quickly during cold and when it get hot, it will have weight of 40.. You know I may go wrong with my thought process and will wait what u recommend and pls kick me if I went wrong..

[@senia.samoata.7607]

True original stuff that is carelessly handle by bush mechanic's Thanks for the video

[@nobody1574]

I had that same bolt snap on my 92 talon it didn't trash the motor but it did destroy a clutch and crack a bell housing.

[@omarrserrano9607]

WOW! Thanks, The cars going up and im checking for that mystery bolt!

[@aperioguitar]

That was very informative. Thank you for sharing your in depth knowledge and expertise.

[@g6qwerty]

That's why its always a good idea to replace any bolts or missing bolt, or ones you lost anyways.

[@Enakaji]

I recently replaced the transmission on my 88 Colt C50 and even on the small 4g15 Engine that Bolt is hard to reach, it sits directly between the lower Crossmember and the rear engine mount and there isn't really enough space to use a ratchet down there if you don't have a carlift. I used 2 long extensions and had a friend operating the ratchet from above while I was holding it in place from under the car.

[@facundolopez7346]

Congrts for the fine analysis. Keep It coming. Thanks!!

[@domestickilla]

LOL Jafro its yours bro if you want it.. it was in my old Groden Aluminum Rod motor.. now ive got a Manley Billet 88mm crank so i dont need it.. send me your Information and its yours man.. i love your channel and enjoy helping fellow DSM'ers and would be honored to contribute to your project

[@cowmilky]

Weather you like it or not i learned quite a bit. Thanks for the Great vid!

[@Bevoin1970]

Awesome Jafro! simply awesome. As I was taught many times whilst in engineering, anyone can get "in the shit" its how you get out of it that makes the difference. :-)

[@kafoure93]

Your still awesome. Your full of knowledge and thanks for sharing it for everyone to learn.

[@sivucit]

Hi, Nice Video.. Excellent demonstration.. tempting to see ur videos all the time , even if I am busy. I assume fillet radius is at the both side of Journal where bearing rides, is that right..?. what should I look for at radius

[@4G63addict]

Great video BTW Jafo. I really enjoy your professionalism and attention to detail. Go skins!

[@jamesdouglas6748]

Sweet update jafro. I thought that only OEM mitsubishi oil filters had the bypass valve in them! luckily they are only 6 bucks.

[@JDWard-Jeepster]

One small inaccuracy, after grinding and polishing the crank can be nitrited to reharden the journals or even built up with hard chroming. You would be suprized how bad a crank can be and still be saved.

[@Jafromobile]

It's a platitude. There are most certainly magical metallurgical techniques that can fix anything short of being twisted into a pretzel. In that regard, I totally 100% agree with you. I thought I said "it's really hard to put back on there", not that it couldn't be done? I'm having a hard time locating the place where I said it... but if I said it couldn't be done, it's because the majority of machine shops the average import gearhead knows can't or won't affordably perform that service in-house. The 4gxx crankshafts are popular and durable enough that most people fix this kind of issue by dropping $80 at a junkyard for round 2! :P They don't know what they're missing out on, though. There's nothing sexier than a freshly-balanced nitride-coated crankshaft for your race motor.

[@TCreatorO]

do you recommend adding rare earth magnets to the bottom of my oil pan to catch as much metal shavings as possible and clean them like 2 times a year?or doing that im risking something else? if it makes a difference what car I drive, I drive a 97 celica GT 2.2l thanks in advance PS loved this video man, you are probably the person with the most knowledge about engine internals Ive talked to, thats why I seek your advise.

[@raimondszunda]

That vid was... ...great! Only now I understand how much I have to learn about cars and engines.

[@destruck]

Great, I'm waiting for the next video. I am in the process of putting together a 6 bolt block 7 bolt head myself and any details are good ones!

[@asetech1962]

Great video!! This has always been one of my favorite motors.

[@WilliamDye-willdye]

Given the damage that happens once the bypass valve is activated, I wonder how hard it would be to add a sensor to that valve. If I'm running on unfiltered "emergency" oil, I want a warning light. Jafro said in the video that "oil filters bypass some of the oil, and that's just how it goes", so I guess that a very simple warning light would give lots of false alarms. I'd still rather have that sensor, however, in case there's a sudden jump in the frequency or duration of unfiltered oil events.

[@TripAMD]

this video was so easy to watch, nice job man👍

[@christophersaa]

Awesome video! you gave me a much clearer understanding of what could have happened to my engine. My car is a 1997 STi with an ej20k engine which has a center thrust ( old engine ) the thing is that my center thrust failed causing crank walk, which then lead to wearing on my bearings. All this happened after I push and pull the clutch ( like a clutch kick) to powerslide the car ( stupid driving habit I had). I wonder if by reducing engine and tranny movement this might help? the addition of stiffer engine and transmission mounts, what are your thoughts? considering that the engine and tranny moves forward and backwards in a subaru... I was thinking about installing this for an improvement but if this will compromise this i would rather not. Thanks in advance, Chris

[@deknaap7]

He jafro, just want to say thanks for your contribution in the dsm scène! Always learning alot and enjoy your way of filming! Every time i just wonder how you know all about this lol! Ok just a small question. . Can i check this bolt with the transmission in place? Or do i need it to remove from the block? My clutch always engage with a small some sort of chatter feel in the pedal. Using stock clutch and flywheel.

[@blksentra2]

Yup! That bolt is gone, sever endplay on the crank to the point we didn't even bother to measure. About how long do you think it would take to start seeing damage on the bearings from that missing bolt?

[@AlchEm1st88]

Thanks a ton for posting this! Very informative. Actually this makes me wish I still had my old Evo 4 block laying around. Would be interested in looking it over again to see if I could figure out what exactly happened. It had .072in play in the crankshaft. You can see it in my "balance shafts and bad crankwalk" video if you're interested. Still have the thrust bearing haha! Good paperweight. Gone to a USDM Evo 8 block now.

[@catocaster2985]

Dude i like the way u doing your video, thats really nice.

[@Twinturbo120]

Oh shit! Could this be why my starter bolts are loose? Can't wait to start tearing it down to find out.

[@beldarremulac9811]

You can come to my shop and we can build 4G63s 6G74s . Your rather good for a young guy. Well done.

[@K0nst4nt1n96]

Could a 2 mass flywheel if not installed by default help in reducing the torque on the crankshaft? Very interesting insight! I dont own this car but i am always interested in these kind of videos.

[@MEZ92]

It's a must have haha. What were your goals for this upcoming build compared to the colt?

[@crobulari2328]

Needs crank grind and full o/haul. If you are stuck then polish the journals up with 400 and 600 paper. Fit a new set of preferably lead indium shells, re-assemble and sell it !!.

[@PheazibbleKneads69]

Great video ! Keep up the clean work ! I loved the tips.

[@martinda7446]

PS. Hello from new subscriber. Great stuff - Really top quality.

[@philr300]

Excellent video. Thanks Jafro.

[@johnestey9041]

3/4 rods spun and if it was bent why would the thrust/#3 main be the only bearings with extreme wear like that? I would think itd be more like 1&5 with the extreme wear if that was the case. your 100% correct .015" end play is a significant amount of end play. just curious did you bother placing the damaged crank on a balance machine confirming it was bent? this is interesting. could it be that the bearings weren't perfect and journal originally wasn't in spec? what brand bearings?

[@jorgegomez4668]

Amazing video! Learned a lot... Thanks

[@topninjaclass]

that bolt is missing on my evo 3
