- Its a sad day in the shop as we pull apart the RB28 in the GTR. In the last video I showed a clip where I mis shifted and threw a check engine light and limped the GTR back to the shop. Lets figure out what we damaged.

Granny shifting… not double clutching like you should. Now me and the mad scientist gotta rip apart the block to fix the piston rings you fried. 🤦♂️
U funny 😂😂
😂😂😂😂
😂😂😂 #DomTorrettoVc😂😂😂
Hell nah 😭😭😂😂
I'd say Adam won this comment smack down! lol classic!
Make sure that you check piston to deck height on every piston while you have the head off. If you over revel it, had a blown head gasket, and coolant leak issue, you could have possibly bent a rod, or squished a rod bearing. Good to check now before you slap the head on.
Sounds like the headstuds weren't retorqued after a some heat cycles to me.
So glad it was just the gasket and that you didn't have to buy a whole new head or block
Clearly a head gasket simple replacement 5 hour job and back driving. The head can be easily removed in the engine bay. But i understand the overkill of removing the engine for the dramatic video effect.
Ouch, you got lucky man
think about the cylinder pressure created when you money shift. its like engine braking x 100. lucky its a headgasket and you didnt bend a rod, or a valve. fyi youre mean to re-torque the head studs, i dont think theyre stretched i just think theyre loose
Don’t let any of this distract you from the fact that Hector is going to be running 3 Honda Civics with spoon engines, 3 T66 turbos, with NOS, and a Motec system exhaust.
HAHAHAHHAA Brilliant!!
If you didn’t come from tiktok raise your hand 🤚🏽
Been here since the beginning... OGs RISE UP 🙌🔥

So you are a little kid ??,
Leave it to TJ to wait 2 years on a build just to mess it up a week after delivery
It's comical how easy it is to shift from 2nd gear to 3rd gear in these cars. I honestly laughed when it happened considering how easy it was to shift this car when I drive em.
@@jesseortiz9007 but but but the transmission was cold 🤣🤣
@@bg710 rookie mistake
@@jesseortiz9007yeah but right hand drive is honestly very easy to confuse
@@emilianofajardo9487 Shift pattern is exactly the same, only thing that changes is what hand you use to shift with. RHD doesn't change the gear pattern
I know it’s a bad situation. But these in detail videos are the one 👌
Didn’t hear you say it but it would be in best interest to also replace those studs if Ian is saying those rear nuts didn’t crack when removing them then it is highly possible that they won’t torque down properly not 100% likely but it’s better safe than sorry
probably they werent torqued right from the beginning
they are not reusable to begin with and im sure these dudes know that
Nah bro, the goat went to the goat, spent goat money to get the goat built. No way they missed a torque spec. 🐐🤣🤫
@@toft5320 JB weld fixes everything.
@@boboso7238 you ain’t lying I jb welded my drive shaft back together 4 years ago after it split in half and it’s still together vibrates a lot but it drives
This is a really painful video, but I appreciate this type of video. You're incredibly open & honest about a shit situation and we appreciate it whole-heartedly. These videos are great none-the-less.
Really not that painful at all if it’s just a head gasket. That’s like best case scenario
its just more content to make more money bro shush
7:07 His face followed by Tj's look on his face like "this is not funny" was priceless😂😂
The reason you always take out all the spark plugs to do a compression test is which it should have showed up in your test is if it has a bad spot in-between two cylinders with the plugs in it will not show up but with all plugs out it will 99% of the time
But compression test was still good 😂
@@xiukn8 that is why I said 99% of the time
The valves open and close giving an escape point. Plugs wouldn't really change that. As seen from no variance in both tests.
@@duanebailey6253 I have been working on motors for 30 years and like I said it matters most of the time but like I said not always. It matters how bad the head gasket is blown. TJ's if you look it wasn't bad because he shut it down fast, if he kept running it would have especially when it eats a grove in the gasket.
Did you guys see the chipped valve? This kind of gasket blowout is common on 10th Gen civics
Yeah, can’t believe they didn’t see that.
Fr
Came looking for this comment I was like surely they noticed the chipped valve
It's not chipped, just some crap on the valve.
Didn't tommy say the headgasket was sketch when he was building anyway?
yarrrr
How so? And why use it if the builder admits it's sketch?
@@171JUSTIN basically said that by design the gaskets can leak, but they don't usually give problems. But if they do, just replace them, but saves money in the initial build.
Tommy is sketch
That engine was fk from the moment he started it. Ity smoked so much. I think that Tommy might made a mistake.
If you remember a few episodes back during the build/tune on the car, you guys had mentioned you noticed a good amount of smoke coming from the tale pipe which could have been the start of the gasket going 🤷♂️
13:20 you have a broken valve as well
Saw that too
it looks like it's the coating on the head gasket
Definitely looks like a piece of the valve is missing, definitely look at the valve next to where the head gasket blew, it may just be carbon but even zoomed in on looks broken
yep, and that's exactly what lifted the head
Yep
Imagine paying $70k for a motor then money shifting 😂
He payed more than 70k buddy, over 100k
he will keep making vids until it pays for it
he's a millionaire - this is content.. wish i had a staff working on my cars while earning money 😂
The S2000 has more than $100K under that hood. The Skyline easily has more than that in labor and anodized colored parts, Tommy got to get paaaaiiid.🤣
@@JoshQche paid 100k in just exterior mods let alone the engine 👁👄👁
You need to check bearing clearances after money shifting🤑
That money shift could have caused an over-boost, lifting the head and torching the head gasket. And of course, like everyone else mentions, make sure to replace the head studs. Seems like you stretched the back ones.
Look at the valve next to the blown part of the head gasket, definitely looks like a piece is broken off of it, 13:22
Could be just dirt, the compression test would have shown low compression
it's the coating on the head gasket
solid eyes, that absolutely looks like its potentially chipped
Also spotted this, The valve is gonskies
Bro it looks like grease of carbon build up
If you get away with just a blown head gasket, you are doing alright. Much better than a bent rod or a valve issue.
I'd be more worried about the crank and bearings. Doesn't take much to upset them early on especially with added rpm/harmonics.
How did nobody notice the big chunk missing out of the valve by the head gasket failure? 13:21
It's just some crap on the valve.
Bro I learned so much from this video you guys explained everything so well
Anyone catch that yellow R33 sneak peek at 14:28 lol?
Anyone else see the teased R34 GTT left rear quarter in the end of the video when he puts the hand over the camera! New project?!
Thats why u can't trust tommy to build shii
I totally agree with you
That's why Adam's engine setup on the R32 is very different from the build that Tommy usually does, that's what Tommy talks about in his video.
That is the EXACT area the block fails in Rb blocks, CHECK THE HEAD STUD GOING INTO THE BLOCK!!!! There may be slight cracks showing on side of block.
if you magnaflux the block you should see it. CHECK THE BLOCK!!!!
Replace the studs. Replace the gasket. Check the deck surface for any high or low spots not just cracks
Bearing clearances need to be checked amongst other things as well
I was looking forward to this video YESTERDAY!!!
My Toyota Camry would neverrrr 😂
My Camry Blew the a head gasket first then Blew the Engine a couple months later 😂😂😭😭😭
Leakdown test called it on the last vid. Been through it before. Pressurize it and the air will find a way out. You probably detonated on the over rev it's alot of cylinder pressure. Glad it's only the head gasket I've had much worse outcomes.
headlift, use the same spec studs. If you use 625 and it was torque plated with 2000s, you'll get really bad wear or scratching in the bore later on
why this happends?
In RB's if you machine a bore to be straight without a torque plate, and clamp the head down, the same bore that was straight prior will start to show distortion. Same issue can happen if you significantly increase clamping load on the RB if it was torque plated with a certain type of headstud. Increasing the clamping force from when it was torque plated with ARP2000 headstuds, to say ARP625, can cause changes in the bore which after some use can be visible scratching in the bore, or unusual wear in the tops of the bore.
In this situation would be best to get a new set of the same headstuds the motor would have been machined with @@Raceman
So i guess this means adam has the better R34 GTR 😂
Im kinda shocked that the transmission doesnt have a first gear lockout. Maybe it's a possible change that can be made? I'm not sure at all just throwing it out there.
Its a manual gearbox, MANUAL ie its not an automatic so no it does not have a first gear lock out. Could it be done with a computer and numatics, of course but then you would just automate the shift fully and you have an automatic gearbox. The point is that it takes a certain level of skill to use the manual and that is part of the attraction to master the fast 1/4 or lap. TJ just fucked up here showing off his huge wallet.
@@MrHughk1you obviously don’t drive a manual buddy, they have had first and reverse lockouts for almost two decades. Maybe don’t cut someone down when you have no idea what you’re talking about. Having5 or 6 gears and a lock out of 1st doesn’t “basically make it an automatic”, you just don’t have a permit yet so are going off of video games.
@@yourdaddy9622 Reverse yes, first is pointless even if it has been done as if you do one you need to do all as you are de skilling the driver, which makes it basically half way to being an automatic, only a clutch actuator is then required. Dont be so presumptuous yourself, im 56, got a degree in mechanical eng and work on cars and bikes for fun. And remember we are talking about early 90's tech before people catered for the lowest achiever at the expense of everyone else. Getting an award just for turning up breeds idiots like you and the commenter.
@@yourdaddy9622normally done on the shifter. It's a pain in the butt for a street car though.
@@duanebailey6253 like as much of a pain as literally changing every bolt on the car? You know, like he did with Tommy… yikes
That's super weird that it blew the gasket. I wasn't expecting that purely because it's not common considering the circumstances. Must just be how the motor is spec'd out.
I suppose because it lifted the head
Exaclty, that engine most probably had bad timing due to the over rev, then it blew the head gasket. With only the head gasket blown it can still rev up and run, even the first compression test was ok so the car should still run. Also you can hear it miss firing evenly not only 2 cylinders.
its actually a very common thing to happen when a head is lifted, especially considering the motor was over revved, its not like lifting a head from to much boost or not good enough head studs, as well as the head being lifted, there is so much combustion at 10-11k rpm or whatever rpm it may have revved out to, im surprised it didnt blow the head gasket worse
This is why you always check the studs after the break in period. Things change after a few heat cycles. But even still the added harmonics from the over rev will be enough to damage things. These blocks have no bracing at all. The spoon ceo breaks it down well comparing blocks. Think it's when they rev the b16 over 11k.
TJ, Also get the replacement parts that you need when you do maintenance, like main seals and any other seals that need to be flown in from Japan. You can cover each part with vasoline (assuming they are ok to be contacted with petrol )and vacuum seal them with a vacuum seal bag. then when its time to use them degrease them and clean them nicely so you have the parts on hand. Keep them away from sunlight and oxygen and they should last 10 years
My moneys on that head gasket being poo since day one. The mis shift just nailed it.
When the builder says the gaskets are crap and doesn’t replace it with a trusted brand to keep costs down on a half million dollar Datsun there’s something not quite right.
Woah what happened ? Didn’t I watch this yesterday 🤣 either way, poor FineSpec😭 we praying for y’all🙏🏼
i was triple out
trippin
When i tried to watch it yesterday it was set to private.. something was likley cut..
bro! the oil splash covers in the head, over the cams, are in an RB25 configuration.... not the correct RB26 configuration for the valve covers and baffles.
Check the valves for seal, the most common result of misshifting is actually valves touching the pistons due to very high rpms at that point.
You might have bent a valve or two.
Leak down test is good impossible to have bent valves.
They would've known when they did a second compression test
13:20 shows a broken valve
@@jonathanclarke452You are wrong lol is just carbon on top of the valve... they have done leak down is impossible to have bad valves
@@fabini14 lol? Chill with the big brain attitude. It might be but there’s a lighter colour gold in the crease where I think the crack is. I didn’t see the compression test so it’s just off their word. Wouldn’t doubt them trying to sell parts and be less than forthcoming about their condition publicly. Could have just been overlooked in editing. My engine has better compression numbers than this but bad leak down. Still drives fine and have run it like that for years now.
not gonna lie. tj u scored big time with bringing Ethan to the team. mans a automotive monster.
Tj u NEED to call the AUSSIES to build u a proper engine. Getting the zinc bolt on can guy was the worst decision u have made
TJ bricked his $100,000 car 😂
If I had to guess $100,000 is an understatement…
Bro, thats worth way more than 100k
Try more like $250k +
He could brick a $5 car or a $1,000,000 car… it’s TJ, he’s got ZERO clues about cars and it shows in every video…. One of the reasons I watch it is to get a laugh at someone “so accomplished” in racing and cars knows absolutely NOTHING about cars and can only read a script and not a repair manual…. Sad
pretty standard feature for every tommy spec engine.
I really enjoyed and appreciated you guys brainstorming and explaining what it was you were doing and seeing, from someone who loves cars but has limited mechanical knowledge, it was great!
Sounds like typical work from fyeah... He only used 20% of the parts so as soon as it saw high revs the coils dildo'd the engine
Did you even hose the gasket down with copper spray and say "that ain't goin nowhere" 😅
Hopefully its back up soon! Get a straight edge and feeler gauge to check the flatness of the decks, too far gone would just cook the new head gasket.
Check the oil. Sounds like a spun bearing. It will go away and come back. Engine didnt sound right and knocking in certain points.
why'd you take down the video from yesterday, did you not want people to see the yellow r34 in the background that may be the next giveaway car or that tommy is coming down to help and do another project?
Awfully specific comment lol
If you look at 13:26 there is what is looking like a burnt/broken exhaust valve
Hey TJ hope everything goes well brother 👍🏽
Who else was able to watch yesterday? Noti Gang!
Hi TJ. So when are you getting a NSX? ;) Love the content!!
YELLOW R34?! I see you
Blows my mind just how little TJ knows about cars…. Truly mind blowing! 🤦🏼♂️
agreed
Could be worse. Could be DDE.
Well, I mean these guys aren't mechanics. They're TH-camrs with money. I mean, I'm sure they know their fair share. But that's why they hire other people to work on their cars
Too busy putting rivets in widebody's to learn about engines
What did you expect? As others said he’s a youtuber. But from your comment he still probably knows more than you. You just criticised without giving any advice.
2 guys who do know. 3 if you count tommy took a while to figure it out. But I’m sure you know more.
Bro 13:25 that valve looks like it’s missing a chunk out of it.
I saw the same thing at 13:09. Glad i wasn’t the only one.
yesterday before the video was removed, I saw a yellow Skyline, unable to tell what model
Did you see that whistlindiesel destroyed the rear diffuser on the huracan he bought from you
13:28 doesn’t it look like the valve has a chunk missing next to where he’s pointing
All good champ it happens. Ive had a good run with RBs. Many years also broken some. We drive them it will happen. See ya at Laguna. Ps
You can rotate the engine with the alternator or power steering pulley.
The compression test wws definitely wrong. Best is testers in each cylinder one shot and done and or all plugs out, fuel disconnect (cas plug) WOT test.
That being one of the nismo special specs call them they might rebuild it
Happy to see it finally Uploaded. Because yesterday was taken down.
But because everybody knows more about cars than me and because I'm wrong why is it such a big deal if you shift into a wrong gear why would that hurt the engine?
I would likely get a copy and paste reply from Google😂🤣💀
I know very little. But just from watching car channels. You shouldn't redline the engine. And when you shift down into a lower gear when you meant to go higher, the rpms are going to spike and more than likely rip past the redline. Which can cause the problems shown and explained in the video.
@@IAmPyrofan Well what happens is that if you go from let's say 2gear back back in to 1gear. Let's say redline is 5k. You would be at maybe/likely 11k rpms in 1gear. That would put crazy high stress on every single part of the car Engine and transmission side.
So over all it's very bad. This is also why I only like automatic cars. Because I have a hard time seeing what gear I'm gonna go in if it's not a gated shifter. I do know how to drive manual I also have manual bikes. But to me it's a lot easier because you don't have mistakes like this.
But that's coming from a person like me that's on the spectrum so somebody can easily argue and say that I'm wrong because I'm not good at arguing 😑
I genuinely wonder if any of these guy actually like Tommy or are just using him because there's no other alternative. Could he have been anymore condicening on that phone call. Maybe just explain what they did wrong without being a dickhead. The guy seems like a bottom feeder
absolutely, what a toss bag. He thinks his JDM, but just a biter
Suprise suprise another blown scamyeah rb 😂
You sound defeated in this video I'm sorry to hear. As a fellow GTR owner I can tell you they will always give you problems lucky you have lots of money to fix this
What kind of problems? Can you describe
Awesome video as always TJ Hunt and Crew. It's going to be all good TJ. Like you always say keep moving forward.
13.26 is that a piece of the valve missing?
13:28 isn’t that a chipped exhaust valve?
The second TH-camr car Tommy scamyeah has messed up 😂
RB26 problems. Thank God for the 2JZ
Just put some rad stop leak and ship it lmao
Fly Josh out.... or not but damn unlucky, dont be that excited to shift, just chill :)
Did anyone else notice the yellow R 34? 👀👀👀
Definitely would recommend the OTC compression and cylinder leakage tester
more money more problems !
I’ve built a couple RB’s that are still living at high horsepower. What you should really do is deck the block and head, and use a Nitto head gasket. They are basically an O-ring style gasket that work great at high horsepower. They just need a fresh/flat surface to work properly. Also, I always set the head on the dowels and then insert/finger tight the head studs. Torque up the nuts. Start the engine and let it warm up. Dump the oil and then rip the valve covers back off and retorque the head studs after a heat cycle or three. Also, not money shifting helps a lot. Something, something mechanical sympathy. Screw that, I plan on CRUSHING on my 2.8 Nitto build. Good luck bro. Love the RB content.
The smart play would have been going to a reputable builder and use what he recommends for the build. Would have been a quarter of the price and handle way more power. N1 crank with aftermarket rods and pistons for the win. No twin turbo nonsense. Way less heat and no need for low end tq in a turbo car.
@@duanebailey6253 I agree. I’ve used the same engine builder for 2-3 RB builds, with great luck. And all of my builds, including my current Nitto 2.8 stroker have been single turbo. My new build is also going shimless bucket, which I’ve never done before, but I’m hoping I will be able to rev this bad boy to 9k rpm or higher if it’s still making power up there! Just trying to help TJ because not many people build RB’s over here yet, and they require almost no margin for error. His HKS stroker would have probably been fine if he didn’t money shift, living at ~600whp, but since it’s all apart, I would recommend doing what I said. Get it to a machine shop, get it all checked and decked, and re-torque the head again after a few heat cycles before turning up the power.
It's true that it's difficult if you don't know what to ask or ask for advice on the RB engine, this is the same thing that Adam experienced when he first had an R32 sedan and he met the GDR god Andrew Hawkins
@@BrianCrofoot
TJ Is that a Yellow R34 I see!??👀👀👀
Please take care of this car it’s a dream for most of us :)
Surely I'm not the only one who saw that the intake valve below Tommies finger at 13:42 is broken and has a clear chip in it.
1000% broken valve on intake cylinder 4. I just zoomed the video in to make sure it wasn't grease or something dark sitting on the valve, it's not I can clearly see the metal is sheared
13:27…is one of the valves cracked? Or am I seeing dirt or grime on it making it look that way?
15:05 yellow skyline with pink rims? o.O
Uhhhh a yellow r34 at the end 😍
when you striped the motor the first time was there not already a blow head gasket - and when you guys assemble it did the measure the block and inspected in-between the a straight edge and a feeler gauge or did you just assembled it before assembling this engine please measure and do a die test on the block as well by dyeing the block and taking a marble counter top that is straight and run it back and forth to take the die of and if all the die comes of its right but if there is still die on between the cylinders then you now you have a low spot as well check on the head of any low/high spots you can check by just you're eyes
Rookie move man. Not cool 😅👎🏼
spaced metal head gaskets are the way to go, Turbo L series motors only last with them because the extra space allows a more forgiving combustion gap, and the metal has a lower chance of blowing out.
Yea 14:28 we see the yellow body kit
Was that a yellow 32 at the end 🤫
Get a Fire ring head gasket.
14:29 another R34 or R33 GTR? 🤔
as well as on you're tune file on first gear what is the flow rate se for fuel it might have gone into first gear and requested more fuel causing detonation with over fuel pressurizing and then blow the head gasket
Hug bummer but the issue could have been way worse. The Bloopers were great. You should bring them back in every vid 🤘🏻🤘🏻
Crazy I thought you posted this yesterday but couldn’t find it!
Honestly gotta say, very sad this happened but this is one of the MOST interesting video you ever put out, digging deep into a rb26 is really fascinating, learned alot
Stop scratching your head 😾 😾 and start scratching your balls 🏈 🏈 bro😮..... could be a sack issue 😕😅🐔🐔🍗🍗if thats not it id suggest double head scratching fallowed by a ball tap or 2 and repeat 🐔🍗🐔🍗 if the ball tap dont fix it ....... wait a second😮😮....... why the hell you even listening to me im no macanic 😅😂😹 😂 TJ I really hope this helps.
