Do this type of stuff more often. I enjoyed it
A C blow up a motor more often?😂🤣
Im joking ofc i get what u mean
@@henry-5899 Full Send !
Because they actually did work and not spend a 20 min video with 5 mins of actual work and 20 mins of talking
check out @speedkar99, he's got a lot of teardown vids and explanations
I have worked on many GR series engines since they were new. Every time I have seen the cylinder 6 bearing be spun has been due to either being ran low on oil due to oil cooler ruptures or having a ruptured VVT-i supply pipe for bank 1. Bearing 6 is the last bearing to receive oil in the engine. Most of the time with that failure, the exhaust cam gears will show some separation as well.
Vvti had metal lines and they did their own oil cooler. You don't think it could be from the first start up?
I'm losing hope that i will ever solve this noise problem czcams.com/users/shortsKk3kyzKZew8 Maybe You know what could this be?
My engine did the same thing this one did. Same exact sound and eventually metal in the oil. Buying a new one soon..
Does it make sense to observe a warmup period? Could it be that simple?
Lol pro tip: usually if the bearing stays on and doesn’t come off with the cap, she ain’t gonna look too good
LMAO did you see how tight those main caps and rod caps were? They couldn't get it off with two different impacts so they went to a pneumatic.
BushWookie73 doesn’t matter if u ever rebuilt a motor you know if you don’t you don’t no use getting frustrated lol
You guys can sure beat fast and furious with your car creations. The MR2 was a with of art. The conversion alone from 4: to 6 cyl in that cramp mid engine required a lot of automotive engineering skills. While it broke down as the new owner was about to take it home, it didn't disappoint me at all. I saw your you tube channel accidentally thanks to social distancing with this pandemic. As a store parts manager retiree from one the US larger auto parts and service chain, I'm impressed by your enthusiasm, technical expertise in every vehicle that you work on. That MR2, Nissan 240sx, Subaru STI are examples of what highly skilled technicians like your group "Throittl" can do like an artist that executes painting murals or sculptures. In the 25+ yrs with that auto parts chain, I never saw a tech that would work on a car that would do it correctly the first time. The come backs I had to put up with. The technicians were there just there to make money at the quickest possible way bc if commissions on parts and labor, but at the expense of customers who may find the service done to their cars are not worth the money. You guys will do the work to satisfy your customers. Wish I discovered your you tube channel much earlier. That MR2 would be worth winning as it was manual transmission. Will continue to watch your channel from New Jersey. BTW, I still drive 6 speed manual transmission 05 Nissan Xterra 4x4. It's got only 55K miles on the odometer and I'm a real senior, senior that never owned an automatic transmission vehicle.
proof that a video doesn’t have to be an install for it to be entertaining. just needs father Mic and Beckerman to host it and Victor with the top notch editing. sick videos guys
Nice beauty shots at the end there!
It'd be really great to see a follow-up video of what you'd need to do to fix and reassemble the engine!
Thank you some much for making this video. I was really curious about what happened to the motor. I think it's awesome that you listened to what your viewers are saying and asking. Seems like most channels don't read comments.
You’re welcome. We read all of the comments every day!!
Woot. Great consistent content.
Would love to see it put back together and put into another car
Yup I would like this also
jose alicea agree
I'd like to see this engine race spec rebuilt, performance tuned and put into another car.
Mad love and respect to all of the motor heads that replied ✌🏼❤️ respect God bless to all can’t wait to see that build don’t let us down 96.2% voted they want to see it done let’s go🏁🏴☠️
Seems rude not to rebuild ready for boost
I love finding and watching videos of finding failure points on engines
So glad I found your channel. My oldest son just purchased a built ‘92 MR2 that is insane. Figured I had better start learning about them for future upgrades. Love your videos!!!
Great job at finding the problem. Enjoyed the tear down process, too. Good luck on future projects.
Love seeing the problem of an engine failure being exposed. Always love learning types of sounds to diagnose the problems.
Totally agree M8. But the cause of the failure is more interesting imo. My guess is it was a worn motor to start with, then power was added. Always make sure the motor is healthy before adding power. Loved the vid and whole series. Hope Brett is loving the crap outa this gem!
@@jerleh261 I feel wherever they bought it rebuilt the motor and left it out.
Wait so it wasn’t the dudes fault for full sending it????
those are teflon coated bearings, meaning it has definitley been rebuilt but obviously not cleanly, hence the oil contanmination and bearing damage
Hence why you never fit an unknown condition engine into a car.
Love this type of videos! Very informative and good way to learn for us. Keep doing thiss like this please!
Love engine tear downs and builds! Keep up the good videos.
I.d like to see Rickie and Mickie.s Rx-7.s running against each other.
Full send Brett 😂
Always dig disassembly. Especially when diagnosing something. Nice video!
Amazing...the development that's come to production....that's essentially a race motor...beautiful piece.....
Did the oiling to that rod journal get plugged or starved of oil by some other means?
Over rev’d ?
You got the makings of a nice coffee table there
Thanks for the update and pull apart of the block.
Awesome as always! Btw, 700k+ Subs...when did that happen! Congrats bro's!
Loved that content.. You guys should build that engine up, and find another MR2 donor for it.. Straight track car with a built up 2GR..
Need another car to go to the track with Mickey... sounds like a perfect reason for another mr2!
How about a Toyota Celica from the early 2000’s?
As soon as you pulled the head off you could see that on bank 2 cylinder #6 had piston to head contact. The aluminum was beaten and somewhat shined where the contact occurred both on the piston and head. That was most of the rattling heard when the bearing cratered. Credit to you and your team that you replaced the engine and got the car going, there really was no other way.
Good catch. I saw it but i didnt even register
My 2006 Toyota Sienna XLE has this engine. I love it it totally elevates the experience of driving, especially when using the manual mode. It is a powerful little thing I can see why they're used in Lotus' cars, at some point I wanna put a turbo in it and upgrade it so it can take it without burning oil/not providing enough lubrication since the Sienna is so heavy.
Rx7! You guys are on point, keep it up!! The Mr2 came out great.
Cleanest engine ever. 😳
I want to know what you are going to do with the motor now. Just have it around for parts or are you going to rebuild it????? With a lot more power?
Trash most likely they no longer have the mr2
@@rushking19 you can put it in any car. have you ever heard of a motor swap?
@@lostprophet356 they have no use for it tho I just dont see them doing that unless they get another mr2
@@rushking19 What? That motor is a perfect keeper for alot of toyota builds.
@@rushking19 it will go into more then just an mr2. you're an idiot if you think the only thing to do with it is throw it away
Bearing will do that when they spin and get hot. Sometimes they are even blue in color. And they mushroom out around the end caps.
Had spun a bearing once and at first thought it was a lifter since you hear it coming from the top. But once I removed the oil pan and rocked the rods one of them was loose. So had to rebuild the engine, the crank had a hairline crack since I drove it like that for a bit.
Who else wants throttle to build a ALL track celica?
Like an 88 All Trac type? Or?
Omaro Acosta what about an AWD Supra?
Yea like a 94 ish GT four
@@craiggotgame not sure how much aftermarket help there is for those Toyota rally cars like the all trac. Would be nice if Toyota would bring something like that back. Maybe we will get lucky and get an all wheel drive Corolla Hatchback Turbo?
Maybe these guys can build a Mitsubishi VR4? Would be cool 😎
@@eppyz they've built (I might be wrong as this is to my recollection) 2 3000gt's and I think one of them was an actual VR4
Lol pulled main caps first when you couldn tell from the sound it was a spun rod bearing!!
They totally pulled that engine apart backwards. LOL but hey at least they found the problem.
Had this on my old evo 6. Completely span the big end and welded itself to the other half. Knew instantly by the noise on the other video. You never forget that noise haha
Check that oil filter to see if it collapsed. Also check the oil relief valve as well is stuck open, this would cause oil pressure to drop both of these failures would cause a spun bearing.
The bearing spun because the pulley was hitting the engine mount which put unbalanced pressure on that rod.
Not possible. That was the #6 bearing towards the rear. If any pressure related issue back there, it would be some kind of alignment issue with the transaxle. This can happen if you do not use the alignment collers.
Probably reved the engine at 1st start up @8000 RPM . There hardly a chance of rod bearing failure at full temp.
Nice work guys. Keep up the great work.
i love content with people that actually know what they are doing. I've got too many projects going as usual. 73 Super Beetle, 83 280zx, 95 BMW 325I vert (E36 problems... you know em), 67 F100 my dad turned over to me years ago, and a 93 GMC Sierra extended cab thats due for some bags and a paint job. Super is getting a body off restoration with all new floor pans and a full engine rebuild, the ZX is a driver for now but you can never leave a Datsun alone, had to swap out a cracked head on the E36 and now im chasing electrical gremlins, 67 F100 got a 2005 crown vic panther subframe up front and has a 4.6L waiting to go in til i find a coyote. so much to do, so little money
Any plans for that engine since most of it is in good condition?
thats what im sayin
It's cheaper to get another used engine than to rebuild it.
@@allanb3222 not neccesarily..another used engine could be a ticking time bomb as well. Rebuilding it could garauntee the engine last for a long time. Also you can build a race engine with it insead of just chucking in a stocker.
@@allanb3222 They opened it already so, half the job done
@@allanb3222 they make money off of these videos, meaning they would actually MAKE money by rebuilding it, so its actually not a bad idea
Damn, shout out to that V6 staying together for the ride back to the shop, with a spun bearing.
had the crankshaft actually break diagonally in my buddy's 65 MGB and we made it the 20+ miles back home in it. tore it down to see what happened and couldn't believe it when the crank came out in 2 pieces
This type of stuff is great. I would suggest for a basic teardown be done when you get salvage engines. Maybe the first engine had damaged bearing surfaces when you guys got it. Taking a look at crank and rod bearings is a pain in the butt, but could save you guys a lot of time, if you happen to get a hurt engine. You guys do amazing work.
favourite build on this channel no doubt!
I thought it would've been a blinker fluid issue
The way it was ticking I think this had a very high likelyhood of being the issue. They should still check it just in case thats like 50hp right there!!!
No, the knocking we all heard was a bearing that was slightly damaged once he got on it he spun the bearing even more we don’t need tear down to know it was a bearing. Oil pump probably failed. Also next time before you take an impact to the rod wiggle each rod whatever one has more play will be your spun bearing. I remember when I was first learning on cars too keep it up guys you’ll get better!
Nice work gum shoes 😂 glad y’all did that it was entertaining and educational all in one. 😂 content like this is a cool change of pace sometimes...
Good job lads. Not everyone would do such a responsible after sell service. Brad is absolutely delighted I reckon.
Ha! My diagnosis from the first video was correct.
You could hear that bearing screaming a mile away.
I'd bet either the rotating assembly was not assembled/torqued correctly OR the VTEC solenoid was not functioning properly and didn't allow enough oil pressure idk anymore LoL 😏
Toyotas dont have vtec, they have vvti of some sort. I wish toyota would make a vtec system
I've had a 2gr swap for the last 3 years with around (15-20)k miles, beating the shit out of it. I'm very curious to see what went wrong with your build and appreci5that you took the time to film it to possibly help other 2gr mr2 owners.
Whoever rebuilt the engine Probably oiled the outer part of the bearing where it contacts the block,referring to the reassembly guide it states in bold letters to not oil the outer parts of the bearing only inner part.thats prolly why it's spun.
Still have no issues with the swap? 15 miles in, my engine did the same thing as theirs 😢😅 sucks! Taking it back out..
@mushlove6933 ohh no. That sucks. Yeah, it's been almost 6 years now and it still runs like a champ, even with autoX and still beating it like it owes me money.
@@MR2GR thats good to hear. It makes me scared to drive the swap since i feel like the engine is so sensitive!
@@MR2GR lucky. Lol. Does your 2gr have coated valve covers? I did mine but did it right. Removed baffles and everything.
How in the world you can take that thing apart and remember how to put it back together blows my mind! Us no mechanics love this stuff too! Fascinating!
i was doing this at 12 years old. fully rebuilt a 72 model 455 Olds Hurst Rocket and dropped it in my dad's old 67 F100 just because i had it and the 289 that was in it ... you got it.. spun a rod bearing. of course we became known on a first name basis with every gas station in the tri-state area. 6 miles to the gallon.. 8 if we eased off the pedal some
@@WrenchS13 Fantastic story! Thats what it takes, passion, fun, work, experience and good times!
Hell yeah boys, didn't think you'd actually do it with how busy you always are!
It seems if they would have done a stock rebuild on the motor, they could have avoided this whole situation.
Something had to be in the oil to score the bearing and ruin it so fast on one rod !!
Earl Moorhead scoring a bearing usually doesn't lead to a spun bearing. Only thing that really destroys a bearing that quick and like that is pure lack of oil.
DirtyMechanic scored bearing shows that there is dirt in the system (in the oil ) lack of oil could also ruin a bearing quick but it would show on all bearing not just one rod 30 years of racing and seeing debris get into motor can plug up oiling system to one rod since there is sign on the other bearing it’s a real good guess that something was in the oiling system
Earl Moorhead it was the last bearing to get oil in the bottom end so if the pump did run dry it it would be the first bearing to suffer. All the scoring will be from bearing material circulating through the engine. Old mate is right just a lack of oil
Ryan Mclafferty lack of oil would show up on main bearing as well as you see all bearing looked new we know it’s lack of oil but why ??? Two things I know one is something plugged the oil hole to that bearing one is bearing moved and covered the hole due to stretched rod bolts or heat the other is something plugged the passages to that journal but to just say lack of oil to me means the oil in the pan ran dry I’m saying I don’t believe the oil pan was low on oil sucking air and only damaging one rod bearing that the sign I saw watching this little bit of info from the video 👍👍🔥🔥🔥🔥
Throtl ViP squad Good evening Evan,Mickey, Rickie awesome the tear down on the MR2’s old motor thrust bearing failure 👍😊
I knew from the Give Away Vid when they pulled over on the test drive!! That noise is internal when a bearing spins. It's a Hellacious Sound! I feel bad you pulled it out then put it back in. Just to replace It! Live and Learn!
Throtle do a muscle car project that would be cool
Something mopar like a super bee
A Restomod build for like a fox body or new edge mustang would be cool. Throw in all ford parts and make it sleeperishhh
No surprise that it was bearings. I was more surprised the engine noise wasn’t picked up before the high revving clip. It was that loud during the drive to the highway.
It could be an incorrectly installed bearing which could have lead to said oil starvation. One can only suspect you deliberately wrecked the engine to provide the content simply because it was that noticeable.
Anyway nice content, because despite knowing it was the bearing, I still watched.
My bet is, they used a "thick" oil, with performance driving in mind, and the guy who won the car smashed the gas pedal when it wasn't up to temperature. The oil cooler didn't help also. Now, I could be completely wrong since I don't remember what oil they put in it, or if they installed an oil thermostat.
Anyways, the video was very interesting and educational in a sense. And the motor sounds absolutely sensational. Great work overall!
heck yeah been waiting for this!
Really cool to see a tear down video on the motor.
I’m guessing it was an oil pressure problem?
No. Oil pump checked out.
@@nwbklr yeah that was my guess in the beginning lol
Could be improper fitnent of the bearing, not lunricated before being fitted, couldve had oil under it when being fitted which wouldve caused it to slip and then just start spinning its not always down to oil pressure
@@Kieran_OPC I've actually seen this here on YT , some obscure "professional" shop doing a 30 minute build video, someone actually putting lube on the wrong side of a cap shell!! Even here, we see these guys removing main-caps from fully torqued down , to fully un-torqued...just buzzing things off as fast as they can..."some people, you just can't reach...".
@@nwbklr So did the bearing...journal blocked.....= spun bearing
My guess: metal went from where its meant to be to where it's not, lol 🤣
Check it out, I use to work at a toyota dismantlers and we found guys who Used the Blacktop/Silvertop 4AGE FWD (Levin) in a RWD orientation, It would spin bearings as the oil pickup was designed to have the oil collect at the back of the sump under acceleration, but now that its in reverse it will starve the pump when the oil collects in the wrong place. maybe dry sump to eliminate that issue next time. All the best with your future Vids, really enjoyed it. All the way here from NZ!
Keep the work up.. Can't wait to start a build
I believe the MR2 would be even more awesome with a V6 option straight from Toyota
2JZ MR2?
@@raverick187 not 2JZ. 2GR. 👍🏻
Honda integra dc5
These last few videos have been excellent 👌
Back when I rebuilt my 4G63 in my Talon, The set of main bearing I received were improperly drilled and only lined up with 80% of the oiling port on #4. I only found this out once it spun a rod bearing and I took it apart and noticed. Sometimes things just don't go right lol
4G63 was a damn good engine though. had a 96 Galant with one in it. the auto trans was crap but I ripped down the autostrada in Italy more than once at 140mph+ in that car. (all stock btw) 3rd and last time the trans went, i junked it rather than ship it back to the states. Mitsubishi knew there was a manufacturing defect in those transmissions too. they swept the filed complaints under the rug to avoid a recall and got raided by their version of the FBI.
For the love of God ditch that S14 tail pipe it makes my eyes bleed every time I see it 😭
It don’t cost much to rebuild an engine especially if ur giving it to a subscriber do ittt right
If it ain't broke dont fix it.
Love the opening!
Crazy! Good work you guys
seen this issue many times. its usually the after a rebuilt and usually the bearing farthest from the oil pump. the initial start up after a build is suppose to be cranking only, no starting. gotta make sure the oil gets to all the bearing before first start up.
Thank you for sharing. This was cool ☺️
Nice one you guys! Great job.
Was easy to see by the discoloration around the crank journal, didn't even need to pull the main caps.
Not sure if you noticed but...
If you listen to the video when Brett took it for "full send", you can hear a rod knock before he got on to the freeway.
Top Mark's for the quick engine change
Great detective work. You all do Awesome work, Great VLOG! 😎😎
Detective work? Would have taken five minutes to determine that the engine was junked had they just dropped the pan before fitting it to the car. That’s called sloppy work.
I know this is a few months ago now, but as soon as i saw the flattened bearing in the last video, i knew exactly what happened as i had the exact same happen on my old Scirocco about 10 years ago. No reason, it just spun. The crank looked like a freshly ploughed field...
@ 13:54 you can see heat discoloration on rod counterweights and main journal counterweights (where the bearings installed correctly?) maybe it was rebuilt or ran low on oil and had a quick loss of oil pressure during a pull or hard cornering.
The MR2 had to be the best build till now! 🔥
This is good shit! Its inspiring me to build the v6 in my venza
Bro that was like the best summary of what happened ever!
Awesome Breakdown!
The 3S-GE in my old '87 Celica GT-S threw a bearing as well which sucks, I would suggest rebuilding this engine to be a HP monster
Glad you did this. Had a feeling, but good to know for sure. (Yeah I just found your channel & am catching up. lol)
Since the block and all is in good shape would like to see you guys rebuild it for max hp!
If I remember correctly, it's the #5 piston gets more stress as a result of the incoming EGR gases. This results in piston #5 getting dirty and wearing faster causing additional stress on the rod and bearings.
Might be the flywheel clutch combination that was being used. That's what failure closer to the fly wheel is... Also why I try to avoid puck clutches while it does increase clamp force it also unevenly places load on the flywheel and the next inline, the crank.
Everything else looks fantastic super clean that's a strange one
Only thing I can think is it may have been a motor that started with the soft external oil lines and one failed and got the updated hard lines later on
For the Record. @ 3:00 The noise He tried to play off as the Water Pump Pulley Bolts... I just shook my head. It's the Glorious Noise of Hot Metal In Distress While Rotating! RIP 2GR-FE!
Yall just have a new sub!!
That pully hitting engine mount knocked timing out
You guys are living my dream!
This type of content is really anjoyable.
I've been into cars since I was a kid but I have never torn an engine down before. I plan on getting more into this side of the hobby when I have my own house with a garage, so watching these is extremely interesting.
Is there anything you can do when building an engine to prevent spinning a bearing like that or is it kind of just bad luck?
Thanks for that guys.
Cool video, hope to see that engine being rebuilt.
Hi no thought it had it just does down to the age of the motor that’s all and the miles that’s all the the videos great content so interesting to watch keep up the great work all of you
CylinderSupportSystem.com needs that block for R&D!!! Will send back with closed deck looking pretty for your showroom!!
Had a spun rod bearing on my 5M-GE 1985 Supra, knew exactly what it was when i heard your video 😂.
