- Look who's back! We are working on a Toyota Supra Turbo cylinder head that ingested pieces of foreign debris... or so they say. On today's teardown video we get into it and try to figure out what happened and formulate a gameplan on what's next. Thanks for watching!
Everybody started paying attention to the VVTI heads when the aftermarket ECU platforms were able to deal with it. The earlier computers couldn't be tuned for variable cam timing, so it was avoided.
Yeah that’s right! It all became mainstream fairly recently too.
Guide issues was what I thought without any other evidence of broken bits in the head. Didn’t see it on the exhaust side but was sure evident looking down the intake side with the valves out. Nice forensic analysis 👍👍👍
Yeah! Only thing that made sense. Thanks for watching!
Why do people "hate watch" free RUclips videos 😂 love your videos man
Lol that’s a great way to describe it
That's crazy! That someone would have done all the valves and not noticed the broken guides and even more crazy that this engine ran fine all that time since then!
I love seeing Paul in the wild on RUclips. Between you, Eric O, and Ivan I’d still be loading the parts cannon when I’m working on cars.
Hope your eye is doing better. Dang dogs, anyway.
@@jesse9638😂 in the wild. Love it
@@timothyball3144day 5 and I can finally open it. Such a fluke for that to happen
As a “peer” of yours (I’m more in the rebuilder side), I enjoy the satire. Also it’s good to be occasionally challenged, in a previous video you talked about how lots of shops have nasty valve grinders, I felt a bit attacked because the one I use isn’t the cleanest, while it’s been upgraded to an ER32 collet setup and gives me good results I will now be cleaning the machine up and doing better in keeping it that way.
Thanks for the content
All of us are guilty of it, it’s a pain in the butt to stop production and clean up a machine. I enjoy machining so much more now that I’m not doing it for a living anymore. If you stopped to clean up a machine you’re doing better than most! Thanks for watching, I don’t make this stuff for industry people and I’m glad that you enjoyed it!
Came from that engine guy and his cleaner channel after you were on it. New sub and loving the work you do!!!
Here in Australia we have an answer for the availability of 2J parts.
We just moved to the Barra.
There is some guys doing 2J and RB stuff here.
Thanks for your video, I'm a mechanic by trade, and most people that aren’t seem to be experts on cars and when the mechanic ugga duggas some suspension bolts the experts carry on about torque wrenches.
It's funny being told about torque wrenches when I have $3500 worth of torque wrenches in my tool box.
Honestly ive got to a point on my own stuff not max effort or high dollar i just go by feel, human torque wrench "thats good enough". In my little town we had a local garage and the guy running it had been on a nascar team yrs ago, he assembled everything with an impact. Head bolts, rods, mains everything and had a good reputation.
@stevenbelue5496
About a year ago I moved to a VW and Audi shop.
I was doing an injector and had to remove the rockers on a 1.9l in head injector diesel.
I asked what the torque specs were and my work mate just said feel.
I only ever used to torque stuff because I had crazy managers in the past, so they can't blame you if you torqued stuff, but that was only engine work.
Suspension, just let the rattle gun change note.
Look for Atlas 4, 5, 6 engines
@@shadowopsairman1583 we don't get those here.
Yes conversation with the guy to let you port out the head yes please 👍🏻👍🏻👍🏻
Very sharp eyes you do excellent work
"That variable timing is... Kind of a good thing!" Never understood why people are so hesitant. It's a learning curve sure, but VVT is dope!
It’s why my suv with a 4 cylinder with a tune can make more hp and torque than the twin turbo v6 version and still get 29mpg!
"It's a learning curve" can be said of so many things, but especially the automotive world. Right now, there are still issues with electric, but I faith that they will improve in many ways, including ways that we can't even imagine today.
What, my LS in a PPV Tahoe can only drink alcohol without setting off the explosion detectors 😂. For those that don't like the humor turn the dial, I myself like to watch an admitted parole violator work on stuff I will never be able to afford. 🥃
29:00 😮 damn
Ahhh, Mr. Elgin. One of the saviest cam grinders on the planet..
He was on a beach last week.
I can’t imagine how time consuming this job is but I would love to see you this 2JZ head the works that it deserves.
Broken timing belt syndrome 😔
Thanks Josh, keep the videos the way you have been doing them. 👍
finally a fun motor.
You should get a ride along in the drift car and put it on a segment at the end of a video or something. So we can see hear the finished product
I’ve spent so much time inside a drift car in a past life. That sounds terrible for my back.
@@EngineRehab lol just stick a gopro in the car then, for the likes. *cough* someone in a low cut top wont hurt either *cough* and be like this is the motor, this is how it sounds, listen how smooth it is
@@SonnyHoood that can be arranged!
My boy Brandon supra🔥🔥🔥
20:45 😂😂
How dare you tell me not to take things too seriously.
Keeps your hands off my tenuous grasp of reality.
Only if your orange orange man bad lol
Wut
@@EngineRehab”harmed by color” remark
@@sethbracken oh hahaha
Facts with satirical commentary is enjoyable
I enjoy the satire! It's not so different from me talking to myself in the shop.
Looks like it was about to drop a valve
I think these days the cordless tools have gotten so cheap and awesome and you can control them so gently even the old timers are starting to recognize
In the short i guessed some tuning issue, this was without knowing the fuel type or seeing the rev limiter banging... 😂 Had i known those details i wouldn't have guessed a factory timing issue. I probably would have guessed valve train losing control with the factory springs. It would seem logical that without decent spring pressure that valve was Melbourne shuffling... 🕺
Sometimes its really simple!
I'm guessing a valve guide dropped out.
Edit: or broken and bouncing up and down the valve. Thinking that because you said to comment after you started removing the valves. And you don't see a missing valve.
I'd have to say pieces of the guides???
Great video again Josh and please don't change a darn thing about what you say here. May I offer a suggestion for future videos? On those broken valve guides will you use a pick or something so we have a reference for depth and how much was broke off? It's hard to tell how much of it was broke off even though the camera work is excellent.
They were broken off right up to the counterbore. I may spot face them flat on the other side and drive out the top. I haven’t decided yet. Otherwise I’ll spot face them flat on the port side and drive out the chamber side.
I have a 2jz in a jeep xj still 4x4
That funky intake keeper/groove wear have seen often in 90s hi-mileage I saw I think Honda & Toy 4 bangers. Yours wood seem to be keepers butted and didn't lock stem
Looking forward to the Porsche and emkay two content!
I enjoy real or not ! And if there wasn’t satire sprinkled with heavy dose of sarcasm why would anyone want to watch 😂. Build those babies out to the limit of his check book !!! Thx for making videos
2JZ-GTE engines on stock cams, both VVTi and none VVTi, are none interference. Wrong cam timing or broken timing belts won't bend valves. What MIGHT bend intake valves on stock springs is very high boost floating them or a serious overrev. Drifters like revs and boost, stock springs don't.
I always Brinnel test old heads to see if they've been over heated and gone soft, sadly this is often the case on old 1JZ and 2JZ engines.
As yet good used castings availability don't make trying to reharden them whilst keeping them somewhat straight worthwhile.
YET.... I am not tossing out my soft 2JZ-GTE head castings!
They are very much interference engines.
U should consult with the cleaning guy on what to do with the 2j head..
Yes fix the damage and make it a nice yes yes yes please 👍🏻.
Great content keep up the great work.
LOVE the "just move one" .... remonds me of Hank jr song , only one i enjoyed ; "i dont know , i dont CARE . GO AWAY and leave me alone !!" . JAMSi cleaning guy hits back well too . i guess as a former VERY simple engine shop guy , i love the humor and enjoy . also , i perform one more function with your vids ,occasionally , called "fast forward" . a perfect example of "MOVIN' on" , when Bales Hay Treavor , puts on short shorts and flashes hairy legs ..... i CLOSE MY EYES and ignore .... i kow he attempting to "reacher a broader audience" ....prob san fran .... free country 😮😅 .
i enjoy the different shop equipment and do wish i could start over and now , in my mid 60s have had chance to get away from my "ex" , and start over in retirement and if had a little more CASH wood rebuild shop similar to yours . at this point , i have acquired nearly complete , simplistic NEWAY system hoping to do more L head stuff ; old guy , old stuff . put valve seats and guide in john deere 40 head . 2nd one and love 2 poppers . we are in VERY different worlds , but basics remain and i dont mind learning from a "youngster" either😅😅 Later ....
Tell us more about RB's!!
Oh man. It’s coming.
I'll be darn , there is a max rpm for valve guide ? Look like graphite compressed iron valve guide are better . I heard the valve noise that cause this . It's 100% properly isolated electrical wire not having space around it (thumb distance but i never saw it since most just change part and do not zoom in . But i did not expect part taking vacation lol . Will you properly hot/cold pressfit them or you'll just 100 pound hammer them in ? Valve guide ? If you hot cold you'll need a oven for the head and liquid nitrogen if i recall for the guide .
They get driven in and out with an air hammer. I don’t do differential heating. Just drive them in and out and room temp
He could’ve got hot in the valve, bent and cracked all the guides I would replace all the guides valves seats. Everything have a new freaking head.
Intake valves got tuliped at some point... Just a theory
Limiter bashing limits life
Hmm, spark plug bits?
Do you use your Bridgeport mill for surfacing and grinding valve seats?
Yes i do
My question for you is what material are the guides made of? Cast iron?
They’re a mixture of all different things. It’s a powdered metal guide. Very good. Til you shove a bent valve into them.
Valve float..
The keeper was fretting that valve. Machining tolerances, or lack of seated pressure???
I’d say it was an extreme case of the valvetrain being out of control and the keepers coming unseated from the retainers.
@@EngineRehabHe looked to be easy on the drift control, but yea, I guess maybe. 😂.
Thx for the great content.

Pieces of ring?
A hacker needs to challenge and see if they can replicate your finger print off a video like this. They showed it with keys to replicate keys and get into your house just seeing a key in a video. Interesting if they can get your fingerprint and access your biometric locks like phone.
Atlas enters the chat
Do you do subaru heads?
"VVT is a good thing, engine is not over-engineered"
> engine casually loses timing and bakes its own intake 😂
Could it be the over-engineered varable timing at fault? 😅
It's not usually something that fails and even if on these early vvt motors the values don't really interfere with the pistons no matter where the adjustment is
How do you clean your heads?
Giant dish washer
Didn't they also come in the Cressida?
I think 1JZ’s came in that chassis in different countries. We never got that engine in a cressida in the US.
Right on, I thought I remember someone saying something about the supra engine in a 4 dr at some point. But yeah like mopar, other countries got some cool stuff for sure. Well have a good one. I'm liking your content man!
@@G-regular503 the cressida got an older inline 6 that was an okay engine but not without it’s issues.
It's a 7MGE.
@@melvingrimes7886 be careful. If you say it’s name it will appear in your sleep.
What do you mean it's not real life?!
Are you saying we should believe everything on the internet? Haha
@@EngineRehab Next you will be saying Santa isn't real!
Toyota did engineered the 2jz to handle more power through bolt ons. They engineered the new supra the same way. Even to the extent of forming body panels to handle the aftermarket parts. So I don't know were you got your info on the 2jz not engineered to handle 1000 hp.
Did you even watch the video?
Apparently not,he doesn’t even realize the new Supra is a BMW
Don't think he did
@@Birb_of_Judgehe definitely didn’t
European engines should be ended
Don’t the Germans machine heads anymore???
What are you even talking about? That is a Toyota cylinder head.
I like European engines.
