IT CRACKED THE CRANKSHAFT!! Evo 5 4g63 Engine Strip Down

The Mitsubishi evo 5 4g63 engine gets stripped down to assess the damage to the engine. Upon inspection there is a serious crack in the crankshaft journal bearing. This was caught early which was very lucky

[@AaronUnknownPerformance]

How much horsepower should we go for in the next engine build? 🐴

[@Jackyboy-jh6xs]

Aaron Unknown as much as it can possibly take but still driveable 🤷‍♂️

[@DomBounty]

Personally I think 450-550 bhp as it would be a beast of an Evo and tear up the back roads and the track.

[@TheMRTVID]

Hmm - its that balance of power, money and having the brakes to stop it I guess. My EVO does big power, but everything else is rated for it plus a full cage. 600 is way enough on the road - multiple maps ? - then kinda sensible, fruity and mad options ?

[@Galamesh123]

I’d go for 900 whp! Where did you learn all this mate, your super talented! I bet u have forgotten more than most mechanics no!

[@hassannaqvi4512]

Not sure about that turbo but from experience 500 whp is just about drivable on the road... Anything over 600 bhp would render the car to be a track weapon only. Saying that technology has probably EVOlved (pardon the pun, lol) over the last 5 years so more power may be useable on the road

The more I watch these videos the more I think this is a REAL car enthusiast channel. No cheesy intro, lots of technical knowledge and tips, all about the car and the builds, no unnecessary flashy garage setup. Love the fact you remain anonymous too as it shows that the channel is purely for the love of cars and not an attempt to boost your ego or become 'KZbin famous'. Keep up the good work.

[@53gsiturbo20]

So much knowledge! Just discovered you tonight and subscribed after watching two videos. Really well done straight to the point and quality camera work switching from up close examples to showing from a distance or time lapse. also I have an Evo 6 so that helped make my decision to sub even easier

Really good in depth video mate, personally never had a 4G engine apart previously being an SR20 kid back in the day. Looking forward to the next one.

[@alansmall9071]

Engine box and transfer case will come out as one out the top as done it on mine just took mounts out the cradles both sides That knock sensor looks f****d 😊 and the number one shell looks a bit dodgy I’m running a Carbotech twin clutch with 1275kg pressure plate so hooks up sweet as Your so lucky with that crank I swapped out my 4g64 one for a Simon norris 100mm knife edge cross drilled crank absolute work of art 👍🏻

Your a very knowledgeable bloke cracking watch. That crank would of literally tore that engine apart if it was left.good job

[@georgespiers3404]

Wicked video mate love the detail and some serious viewing pleasure for me i get myself a drink get comfortable and watch it keep up the good work mate 👍👍👍👍👍😁😁😁😁😁 and with a bit more abuse that engine could have ended in tears caught it at the right time you knew something was wrong straight away you can teach your experience mate your the god 🤙🤙🤙🤙🤙

[@lindenwallace361]

Love watching your videos top work keep it up

[@bmxbeck1803]

Time for a nice warm unit to work in💪👍

[@MrStreetboy80]

Not sure if it’s the engineering Mitsubishi have put into an engine that’s impressive or the knowledge you have on so many different cars!! I feel like I’m a couple of videos away from my very own engine rebuild from what I’m learning from this 😆 glad you caught that crankshaft before it snapped, imagining that big chunk of steel flapping around in two pieces inside the block is a frightening thought!

[@kylebrace1600]

Can’t wait for this bro going to be mint

[@shaunwest3612]

Great video Aaron, every time I watch your videos I'm amazed by your knowledge,and you give some great tips,those pistons look in super nick👌,do you think that crank was skimmed to save money or just laziness?,glad you caught it in time was a nasty crack, cannot wait to see your next video, always a pleasure Aaron 👌🙌👏

[@DomBounty]

Save money I'd say, but after spending so much on the pistons and con rods seems odd to skimp out of the crank. The crank would have lasted a lot longer if it didn't loose oil pressure though.

[@MrLorenczo]

​@@DomBounty Well, as Aaron mentioned, there was something done to the crank where it wasnt durable anymore so maybe they just forgot or they had lack of knowledge, maybe they were sick of it and thats why they sold it. You never know what stands behind these things, unless youre the person that did this.

[@astonrichardson4309]

Good work 👍

[@peternufc1981]

Interesting watch mate 👌

[@matthewfallon6564]

I'd love to buy a car off you 😂😂

[@newtechgs7471]

Last owner must have spent a fortune

[@RSADYNAMICS]

A 2.1 stroker WITH a 4G64 block .88 mm 4G63 crank and 156mm conrods would make a great build

[@hi2lenduffy837]

Great work

[@colintx800]

I think this guy is some sort of mechanic.

[@dustinselby4028]

If the crank was cut, the rod bearing would typically be a undersized to fit the crank?

[@HM.Hatchet205]

👍👌👌 quality work

[@itsleelockwood]

love your vids man!

[@scoobymad2999]

Do u take on any work as I need my scooby looking over and you know your stuff

looks like its not balanced and balance shaft removed?

[@Rehbraun]

Did you first build that engine/enginebay?

[@c111prs]

Looks like just water for coolant ?

[@gtrgtrr33]

Great videos mate Norris design make a supercharger kit for these motors Turbo and supercharger 👍

[@thehomemechanic6964]

For the crank / rod bearings, do you use the same clearance stated in the manual for high powered engines compared to 'normal' engines?

[@mrmilner1096]

nice job

Hope you got this car cheap kuz I'd be gutted if just got it and all this happened,do you know why the engine failure kuz fort morris design ment be one the best engine builder's around,or was it old ownership? ?

Fair play mate it seems that nothing u do is a chore and bodged are u a mechanic for ur job cuz if so there needs to be more like u around I’m in the middle of rebuilding my focus st engine and well let’s just say ur knowledge would be great now lol keep it up matey

[@jordanfragola6023]

[@billywhizz98]

Ouch that’s going to be costly

[@brookieant]

Aaron what causes a bearing to spin like that Cracking video again hows the red show astra coming on & the fiesta 👌🏽👌🏽🤘🏼🤟👌🏼👌🏼

[@Chrisallengallery]

Lack of oil

[@DomBounty]

In the previous video he explained that the previous owner had performed an oil change, and put the required amount of oil into the motor, but as the car had an oil cooler, once the car got up to temperature the oil cooler kicked in and sucked at least a litre of oil out of the sump which caused the engine to loose oil pressure which caused all of this damage.

[@marenghi123]

You can reuse a mls HD gasket

[@TheMRTVID]

Just be mindful when on the way to surgery its not how fast you go its how fast you stop ! Your right though EVO's should be mad bad

[@medievilassassin]

WOW! I would send the person you bought this from the bill for the crank shaft

[@feedingfrenzy123]

Sold as seen mate. Any secondhand car (especially a highly modified one) is always a gamble, but at least this was caught in time. Aaron will have the peace of mind building this up himself anyway

[@hassannaqvi4512]

Not challenging your knowledge but if I'm not mistaken the flywheel on this motor will not really gain much by skimming it if it has suffered heat damage... It may be better to replace it. Please let me know your thoughts 👍

[@DomBounty]

If it was a dual-mass flywheel I'd personally replace it, however, a single mass flywheel can be skimmed (will save the owner a lot of money). If the flywheel has any cracks, even tiny ones I'd replace it as well, however, as this flywheel looks to only have hot-spots, skimming it would be ideal. Once skimmed I'd check for any further damage and evaluate it then, but it would be worth the cost imo. This is only my opinion from very little experience, but thought I'd share my thoughts anyway.

Who did the engine rebuild and used a reground crank? Surely norris designs with all there evo know-how wouldn't off done that surely??? Glad you managed to catch it before it totally let go,can't you still buy new 4g64 100mm cranks from mitsubishi???..

shit the bed!!! that was very close to being catastrophic mate!!

600 hp max to make it a fun to drive.

Loving this engine build i think 1000 bhp running on meth to keep temps down with a shot of nos wanna see lots of carbon drip in the bay with some clever grip/stability programs wide stance none of that stretched tyre shit just real wide at the rear an low to the ground like i like my girls😉😉😉 some need for speed shit this gonna be 🙄🙄🙄
