Sammit: Do you know how many sr20's I've took apart Daiki? 1!
Daiki: what!?
Exactly what you were talking about in the Live Stream Fri if nobody else wants to see these or any cars and trucks old or new and all in between you have to be willing to take the next generation of kids and teenagers and get them excited about it first and then if they feel that passion we all have for cars and Automotive Sports they’ll build other cars and keep Grandpas old truck instead of selling it to buy a PlayStation to sit inside all day and never feel what we feel when we drive and see and hear the cars and trucks we love! Someone has to be a ambassador for the next generation!!! And I think Sam is Definitely Doing All He Can!! Thanks Sam!!!! I hope more people heard you and think about it and then go do it!
Daiki is proving his skills and his English is getting better too! Meanwhile his engine is down, but i love the positivity and vibes on vids! Peace ✌️!
Good of you to teach daiki Sam looking forward to seeing the 2.2 build process and putting the car back together
Isn’t Daiki the qualified mechanic?
Today on The Learning Show with Sammit brought to you by The More You Learn The More You Know all jokes aside amazing content and great info Sammit keep up the great work 👍
Bro I want too see alot more of builds for daiki and his drifting ,he is so talented ❤
I love how you took everything that was done and taught to you and you're paying it forward to someone else like Daiki, Sam. Respect!
so nice to see Daiki learning more, I hope he has a better engine in the future
Water/coolant in the cylinder does not change timing or cause detonation, water is actually used in water or water/meth injection kits to decrease the chance of detonation, you guys better check the injectors on that cylinder and get it properly tuned
There is a really good comment above that explains in detail how lifting the head/ blowing the head gasket causes detonation.
@@SAMMIT I'm still of the opinion that it was the other way around, detonation/knock causing the cylinder pressures to spike too high, blowing the gasket out/lifting the head.
Judging by the color difference of the pistons water has gotten into that cylinder and again water would lower the temperature in that cylinder and not raise it. Again, that is exactly why it is used in water/meth injection.
So in my opinion this engine was knocking which then lead to the damage you have there, the detonation may have been caused by coolant not flowing properly through the head although I would suspect more cylinders to have been showing signs of detonation, fuel delivery issues, poor tune, no proper knock detection and knock strategy set up.
I came from your poorly edited short to see if you just minced words on the editing, but no, you are absolutely spewing shite.
the detonation was present before the head gasket failure, and probably contributed to the head gasket failure to begin with.
I'm getting sick and tired of camera holders thinking they have an iota of knowledge about shit
I found that exact same piece in my oil pan years ago and haven't had any issues with the engine since lol
Ever found out where it broke off?
like in the video, it came off the oil pump housing@@Lasenggo
Love the SR content, would love to see how they sleeve the block and the whole process
Love the in-depth stuff! You really get to show off your awesome knowledge too! Awesome work sam and daiki!
Sammit, did you note what side of the piston the rings were on out of curiosity, as they should not be on the major thrust side and that will cause bearing and bore wear. ohh and kerosene is a hydrocarbon, it also contains a lot of hydrogen. The hydrogen, being a very small atom, will diffuse into the steel very easily, and affect the quality of the steel in a very negative way, so prob best not to use on bolts that are under important load - just thought you might want to know especially as you compete these engines
@@LuckyFruitRacing it's mainly for the breaking period, yes they will move a bit. However this is exasipated by incorrect cylinder bore crosshatching angle&depth . Not placing the ring gaps on the major thrust side was the way I was advised back when I used to build drag and track bases motors. I do this on road cars as its just something im programmed to do by instinct. On drag engines we didn't see any rotation - as the engines got stripped after each event (and sometimes during events!), so easy to see any change. On track cars that don't get rebuilt no where as often we would see they move a bit and looked to settle in a position of least resistance, but they were never that far off from where they were initially placed.
Yay, in depth engine stuff. So good.
Usually as long as the bearings don't grab the crank and spin the crank is safe, the piston rings position is it possible that they spun after running the engine? Great content! Yes more of this!
i just learned a ton about SR's , thanks sam 👍
Really ?
In depth technical videos are dope!! Keep em coming!
Daiki sounding like an anime character pulling the crankshaft out made me laugh 😂
😂😂😂😂😂
Another thing that could have causes your rod bearing wear is knock (det). The quick high cylinder presures can push the oil film out around the bearing causing bearing to crank contact. The way you can detect this is with oil presusre logs. If you're seeing quick spikes during high load, this can indicate knock is present. It also seems to me you guys had some oil contamination issues by the bearing wear. With the piston ring clocking issues, I'd guess someone inexperienced assembled that engine and it wasn't as clean as it should have been.
I am glad you made this video. I know very little about Sr and i own one. Still not running but its getting there, i don't know if i plan on using the AC so that heater core trick on looping it did help me figure out a solution for that situation.
I and am sure other find this information helpful when you guys breakdown how a certain engine works.
I think what Sam was trying to say about the igniton strategy was, if you have a blow headgasket, and the ecu is detecting knock, the ecu is going to pull timing out to counter that. On older ecus this is usually done globally, not by individual cylinder trims. It's possible whatever ecu that car has CAN do that.
Now onto some things that were missed a bit. I know you're still learning sam and I also know you don't want to give your viewes incorrect information so this is all love no hate bro.
You were very close on the blow headgaket information but here's what I can add and help explain. As you said, no water flow in the head so it cooked, this excess heat caused the aluminum to expand past it operational design, causing an effect commonly called lifting the head. This causes reduced pressure on the head gasket and in this situation, combustion gasses blew the head gasket seal by a water port. This in turn causes hot combustion gasses to flow towards that blown port (path of least resistance). Those gases have to compress to fit in that tiny crack causing to it reach even higher temps, melting away the aluminum. next injection event when the fuel is atomized during compression it will touch those super heated spots in the head and ignite cause det. So the head and block are getting torched 2x. Once on compression (det) and once on exhaust (combustion gases). I'm surprised you guys didn't mention white smoke from the exhaust. Usually with a failure like this, a good amount of white smoke would be seen. Anyways, hope that help. Now on to watch the rest of the vid.
Really good explanation! Thank you!
So nice dismantling then discovering then planning then assembling then testing and finally competing.
kerosean is awesome advice, ive always used diesel fuel but doesnt work amazingly. but it does work well. run it in the parts washer, ill have to read up more on kerosean.
love the technical in-depth stuff!
Its how you started with OKACHON,
WHY SHOULD YOU NOT BECOME A DEMI GOD OF SR, RB, 1 AND 2 JZs? You are on your way, Sam!
Sam @16:42 when you get aggressive on timing, get detonation you beat the bearings up and get premature wear. On top of that drift engines see high RPM with low airflow which usually overheats the oil causing lower than normal pressure. @19:29 rings will rotate in the bore during normal operation. It is common to get top and bottom ring gaps that rotate from their original position I have even seen the gaps completely inline it's not a big deal and will function 100% fine. The only way to prevent ring rotation during operation is to pin them like a 2 stroke piston.
The miracle is how Daiki was even able to compete. The engine‘s effd, the wiring loom is shite, too. How? How is this possible? Th car must love Daiki very much
I love these more in depth videos, it's a really great way to share your knowledge and passion !
Let’s go Sam it’s so awesome you taking Daiki under your wing he seems so deserving. Let’s go team “Transnooil”
Perhaps Fumoto makes a drain valve that fits the threads so you don't have to risk stripping the oil drain plug.
Awesome video as always Sammit. Sammit your a awesome dude for all you do for your friends especially daiki. Can't wait to see y'all both ripping up the track doing back ways entries.
@sam compressionrings move when the engine is running, thats completely normal and HAS to happen.
Hence why u get engine failures if they get stuck.
There CAN be an overlap of the openings which increases blowby, but usually thats...who cares, itll move again
Literally straight to the point
Hi Sammit ,don't Bother fixing the head after you welled the head it softens the metal And in about 6 months time The valve guides will sink Just find another head and save yourself the hassle speaking from experience
Poor SR. It was definitely tired. You did good till the very end 🫡. I’d watch that boost if you’re making it a stroker.
Great content Sam. Go Daiki 👊 very lucky. 2.2 will be awesome ✌️ 🇦🇺 🇯🇵
My guess is the coolant reduced the efficacy of the oil thus causing heat and friction. Very lucky it didn't spin
Never found where that second metal chunk came from.....man that would give me anxiety. Definetly enjoy the mechanical aspect of the videos more then the drifting itself.
Detective Sammit back at it. Case name Daiki's engine.
Now Daiki just learn how to rebuild engine from Hakase Sam Sensei. Nice 👍
And btw, Selamat Pagi (Good Morning/Ohayõ Gozaimasu) from Sabah, Maresia (Malaysia)
Selamat pagi jugak dr batu pahat, johor, malaysia
Kero bath is a go-to for cleaning parts.
Can even get wash bays that have a pump to spray as well
Hopefully since you found the issues he won't have those issues with the rebuild and should have a good season in 24 :)😊
Looks like a key, bit behind the timing cover looks like a piece of the "BLENDER " rods .
Oh damn, that sucks, I feel for him.
Hopefully it's not too expensive.
And had to be his pro car too 😢
DAIKI got done dirty! But he is now getting right with DAMMIT SAMMIT FFN #11 RACING! OKACHON, SAMMIT, DAIKI!!!!! PAYING IT FORWARD, SAM!
Surely a ve head conversion with your relationship with prp and plazmaman they make nearly everything for it
more engine videos, i like them
Sam you're such a good friend too Daiki I can't wait to see both of you on top of a podium this year I have faith it's going to happen for both of you this year !!! LET'S GOOOOOO TEAM SAMIT !!!
more of this technik videos pleas i realy love to learn about this stuff
cant wait to see daiki perform in competition!
I wish daiki can have a yashio pink color too hahaha
For practicality getting a low mileage s15 and use it as a donor car. Daiki have a longer and better chance with that. Then old engine sell it.
Love engine tear downs
daiki's car needs a full refresh at this point. theres too many problems just start from the ground up
Looking forward to seeing it run. One question do you know anything about the JP Partners out of Kanie, Aichi, Japan? Was going through them for 2001 Honda Civic parts but seen 1 star feedback on Google Maps.
20:00 Do piston rings rotate when the engine is running?
God save this Motor.
Please make a shirt with the Piston Tray Graphics “MY Tututu Stuff” 😂
The padawan becomes the teacher. Sam you are some guy! Sharing wisdom will gain you jedi status soon enough lol 😅 if you guys struggling there is a spare 2j in the shop 😮
ちょっとふんき！😂 Learned a new word today!
that Pocari sweat looks delicious!
🤔maybe have the one crank balanced and checked before using if you suspect it being dropped!!
Sam needs to aliexpress a parts washer at this point.
RiP Daiki old motor. On to the newer and better.
MORE DAIKI CONTENT for sure for sure
I’m creased at you giving engine building advice 😂 after your debacle of building an engine
Daiki run now don’t let him try rebuild your block
gave that crankshaft a good tickle
As much as Daiki learned his SR, am myself learning as well. Great content about SR engine Sam 🫶🏼. Hopefully, his engine running again soon. 👌🙏🏼
oiling issue. get the oil gallery cleand out. the further from the pump the lower pressere it had. and new pump i gues.
Sam. Is there anyway to get any Nissan books you use to build your SRs? Or any other information manuals? I'm in the US and getting my first sr for my 240 and it will need a rebuild one day. Info is scares and misleading most the time.
You can usually find them on yahoo auctions. They are pricey though & all are in Japanese 😅
please do an tear down of toyota camrys reliable 2az-fe and 1mz-fe i would like to get to know how it works haha
i had a 1mz-fe that hit almost 500,000km before the car got totalled
Keep up the great work sam
Your technical level of engine is to high.. Good learning from you Sammit
Love these types of videos very informative
His rings were taking a dumpster dive because of over oiling and cooling! Causing KAAAAAABBBBOOOMMMM!!!! AND YOU KNOW , KAAAAABBBBBBOOOOOMMMMM HAPPENS...!
I’ve always thought they should be 180 for perfect seal
Interesting video but give that humble little man Daiki a real engine instead of the 2.2 SR. You still have that spare 1jz don't you Sam? 🙂
Now I'm worried. My NB Miata also had a heater deletevsome time in it's life... Wonder if they rerouted things the right way.
Oh no! It looks.. chocolatey......Oh no!!
I have been wondering if japan will take foreigner mechanics or is it hard to get job there as a mechanic
Keep up the in dept sr contain im....alll for it...
Don’t lay your crank down like that please stand it up with the nose pointing up
This was a interesting video
if you blew a head gasket that means your engine got to hot, in doing so you will also cook your oil. when you cook your oil it does not provide the protection like normal hence the bearing wear. believe it or not, it looks like you caught it just in time before you spun a bearing.
Those ring gaps need to be in the pin bore corners all in different angles
And like you said 180 out from each other and never lining up with another ring
Bring on the engine rebuild Videos.
Valve at lap fastest section must be ground heate❤😢
Why don't you get a parts cleaned and use solvent. Cleans better than kerosene
I have no experince with SR's (or RB's) becuse you don't see them i sweden, but I would say that 90 to 180 degrees is normal for ring gap offset. The rings spinning is not a red flag in my mind, with the detonation (the only one off interested for ring gap offset was number three, but the detonation damage was in cylinder number two, but detonation is (as far as I understand) a switch over the supersonic "line", and what I know about supersonic is that it's a mess and it is not logical acording to the no'n supersonic rules). But I would say that the head could probably be used with it just being deck't (atlest for a missile/non comp car) and mayby also the block with some honing and blocking (the use of a grind stone by hand over/on top off the bores, atlest for a missile/non comp car)
Hey moondoggie that was great I've bit waiting to see new travel down videos like this ea ..
Daiki sad with smile of face uhm how? and oil low pressure was cause of bad ring positions it got blowby effect
Good to see learning the young next generation
You need a good camera with good stabilisation 😊
I thought daiki was a mechanic. If he has never pull down tbe engine before. Guessing he is not a full mechanic. All good. Is the sr god goi g to show him how to assemble the new 2.2 engi e or will you sam?
Just get him right for the mean time
Yes more content on sr motor the do and don’t
0:03 there was no oil in it again ?
Dyki with you engine should be better
But will be better
sick video bro
At least his transmission is full of oil?
