    These old Videos help soooo much, i can read a bit but my brain always gets mangled after a while, probably since English ain't my first language but videos with continuous explanation is a god send, thx Jafro from 10 years ago !

    I think most of the diy/automotive/machinist side of YT could take a lesson from your fluid and organized narration. It proves that there is indeed an elegant intersection between being concise, engaging, and vastly informative.
    -- and you understand the value of text descriptions too!

  • @tonkatoytruck
    @tonkatoytruck 10 ปีที่แล้ว +3

    Probably one of the most overlooked steps in building motors, especially overhead cam engines.
    Thanks for making people more aware of how much variation can be present after machining, before or after reassembly.
    Well worth the wait for the video Jafromobile. Thanks for sharing with us. It is greatly appreciated.

    A friend pointed me to your channel, and i'm now coming up for air after immersing myself in untold hours of your videos. I'll probably never touch a 4g63, or any DSM motor, but i thank you for the painstaking detail you put into these videos and facilitating the satisfaction of my inner monologue's "i understand what he just did!" I don't know where i'll fit everything i learned in this video, but i'll make room.

    This video I think is the best on the net that I found on degreeing cams. Thanks for the information. For the folks that are still confused, sit down, take notes on a piece of paper and put it into your own terms. Rewind the video multiple times until your brain matches what's on your note pad. Luckily for some, he was using a digital gauge and not an analog gauge. :)

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว

      cruzancoconut You pegged the only reason I use a digital gauge. ;) Thanks!

    Can't say if I am repeating myself but about 5 years back when I was rebuilding the engine of my CRX (D16ZC) you have been the one who got my attention. Even today you r giving us nice insights, tips and good jokes. You brought me into porting the cylinderhead and checking the injectors. And with this video, later on, how to set the cams correctly after the head been surfaced more than 2 times. Heh. Thanks for having u here.

    Almost 300k hits man. This video has definitely been viewed world wide for improving 4g63 skills and overall education of the engine .

    • @Jafromobile
      @Jafromobile  6 ปีที่แล้ว

      I actually think this particular video was the best work I ever did here. I wish it had half the traction of my port and polish video. The would be filled with DOHC experts! :D

    Stumbled on these videos and I'm pretty impressed, the way you walk through these is fantastic. There's no guesswork for the viewer on how or why you did any one step, and that's a big part of what separates great teachers and OK teachers. Keep up the great work, I'll be watching some more of these when I find the time

  • @Gerhardt13
    @Gerhardt13 7 ปีที่แล้ว +2

    I'm that statistic! Hiya! o/
    I love watching your videos, and they recently helped a friend of mine. He suddenly lost all power on the road with his Evo IX, assumed the engine was dead, and decided to replace it. I managed to talk him into pulling it and letting me look it over. Thanks to your video's, I diagnosed several problems and rebuilt it for about~$700 bucks ... Saved him 2.5 grand easy, and it runs like a f**king champ! ^_^

  • @dantannehill5200
    @dantannehill5200 9 ปีที่แล้ว

    I prefer the piston stop method myself, but you know your stuff dude. A VERY VERY informative video. You should have your own show, you had my attention the entire time. And I get bored pretty easy man. One of the best car vids Ive ever watched. Thanks man.

  • @gmbsk8
    @gmbsk8 10 ปีที่แล้ว

    great video, the foreign material stuck to your magnet at 1.35 had me freaking out but i knew you would clean everything up nice like you always do. iv been watching your videos for a good 5 years now and even tho my dsm is gone i credit all my mechanic talent to you and your great attention to detail have stuck with me and every car i ever play with, i rebuilt the motor in my 95 gst way back when and knew exactly how everything worked before i ever tore into it, your videos where the best thing i could have found and i enjoy every last one still to this day. I drive a 07 mazdaspeed 3 now and still miss my dsm maybe one day i will have another. Great job as always Jafro.

    Hey there just stopping by to say Thank you for these amazing videos! Your videos have helped me to fully grasp what it takes to build a motor right and Im using ever piece of knowledge that you share into my 2.4 build! I cannot thank you enough! Your patience and perseverance is outstanding!

  • @ProjoeDiesel
    @ProjoeDiesel 8 ปีที่แล้ว

    @RA24turbo 10 ปีที่แล้ว +2

    Once again youve an incredible contribution to the gearhead community. Thank you!!
    And here is a tip from the blacksmith shop if you ever have to cut on sockets again or anything that may be some kind of hardened tool steel. You can get the metal as soft as they it will get by heating it up to dull red or wherever it looses magnetism and then let it cool as slow as possible which usually means dunking them it vermiculite. (Its like kitty litter and found at pet/garden stores)

  • @gnaloin
    @gnaloin 10 ปีที่แล้ว +3

    Use a bicycle wheel spoke to extend a dial gauge! Some of them have the correct thread to screw into the dial gauge and they're straight, cheap and abundant.
    Also, the correct thread for most of the dial gauges is M2.5 with 0.45mm pitch.
    On another point, I like to measure my TDC using 1mm BTDC and 1mm ATDC of piston lift, as the top dead center is - as the name suggests - a dead center. Depending on the stroke-rod ratio, the piston might seem to stay completely still at TDC for more than 3-4 degrees of crank. I mark the pulley for 1mm BTDC and ATDC and the real TDC is exactly between those two.

  • @240sxmetal4
    @240sxmetal4 10 ปีที่แล้ว

    Just saying. You taught me more about engine building than any other person I have ever come across, in person or on the internet. Your videos gave me the confidence to go out and build my own engine (finally... Had the damn thing for years.), and mixing what I already knew about engines and what you show in your videos... I'm proud to say that my little CA18 runs mint, has perfect compression and does what it's suppose to do! So for that, I have to say thank you. Now I just can't wait to build my next ca18 with much larger cam shafts! Keep the videos coming. We can all learn from them! : )

    I wonder what percentage of adjustable cam gears are installed because they look cool and never adjusted. If there is a better source of this quality of automotive know-how, I'm not aware of it.
    Thanks for all the time you put in, and of course, your relentless pursuit of audio and video quality. I know it does not come easy.

    I remember my cousin putting dohc heads on a 400. grinding the block, drilling and tapping holes, running a timing belt, plugging up countless of the previous timing holes, and shortly there after ruining 1800 dollars worth of top and bottom end. I also remember the day he got it right.... 9800 rpms and 630 ponies at the flywheel. His garage walls were floor to ceiling in math. Now it sits in a Catalina in Florida, Waiting to become scrap.

    There is an easier way to attach a degree wheel: search google image for a degree wheel, print it out, and glue it on to the circumference of the harmonic damper. It takes a bit to ensure it's round and true to center, but mostly free is a great price

      @Jafromobile  10 ปีที่แล้ว +3

      Caboose is an amazing cat. You never know what you're going to get, and I got lucky with that big fat-ass crazy Manx. He does most of the dog tricks. He keeps a line of sight on me no matter where I am in my house or in the yard. He's like a Jack Russel terrier.

    • @MrComaToes
      @MrComaToes 10 ปีที่แล้ว

  • @mrtomsr
    @mrtomsr 9 ปีที่แล้ว

    If I may, an old school hot roddding tip for cam tuning. The motor will respond the best when you achieve the highest cranking pressure by changing valve timing events. A lot of trial and error, but I always had more time than money.

      @Jafromobile  10 ปีที่แล้ว +1

      There's a finite lifespan before you can't even find stuff in the junkyard anymore. The Hyunda stuff from '90-'95 for instance... Mitsubishi won't be far behind. If you want one, get one before they're all gone. Responsible people who watch my channel deserve to own them.

  • @moogz2478
    @moogz2478 10 ปีที่แล้ว

    Love your vids, something that might help with the tapping would be to heat (with Oxy. Acty. kit) the centre hole of the socket to a Cherry red and let it cool in air, this will relax the grain structure of the hardened metal and save your tap.

  • @chilledoutpaul
    @chilledoutpaul 5 ปีที่แล้ว

    God I remember doing this to my cortina mk2 GT, I fitted a kentcam bcf3, it was a little more easier in that engine (kent crossflow) because it was a single camshaft but it was a ohv so the cam was in the block. But I had the head ported and gas flowed,, fitted 1300gt pistons in a 1600 gt block (higher compression), I also fitted vandervell bigs and mains shells and knocked to the oil pressure to 60psi plus fitted a full janspeed exhaust system inc manifold. I left it with the standard webber carb DGAV32. i did take it down the motorway and 0-60 was around 7secs and the speedo was off the clock around 120mph. This was all done around 40 years ago when i was in my teens. I beat so many cars away from the lights even the souped-up ones. The fact was I had done all the work properly and did not just bolt on after market accessories; Those was the days!!!!

    By far the hardest part of degreeing cams is trying to get the damn indicator in the right place in the cam follower.

  • @NZ_BENNY
    @NZ_BENNY 10 ปีที่แล้ว +1

    top video jafro.
    I will definately be making my own solid lifters for this, I didn't realize that it was that simple, here I was prepared to buy some. Be looking out for cylinder head 206

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว +1

      You should lookup 4g63 dotorg and read the cam degreeing section. There's a fantastic write-up with yet another method of lifter setups available. It's nice that these lifters are so prevalent in so many different junkyard cars. Every 4-cylinder DOHC 1989-1999 Mitsubishi uses them. Of course there's nothing wrong with the ones CRCO makes if you have the coin. Heck I might even buy a pair just to have them in the toolbox.

    • @NZ_BENNY
      @NZ_BENNY 10 ปีที่แล้ว

      ***** I am not that far into the build yet my cylinder head is ported and polished and I have all the parts for the head, gaskets and sensors for the engine but am yet to buy a rotating assembly and machine work. This sort of stuff is beyond my experience right now so ill do what I did every other time, watch videos and read manuals then dive in and I will be familiar. I will read this article on 4g63 dotorg thanks. Oh I finally got mitsubishi ASA on my computer so part numbers are a breeze. Keep it up jafro.

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว +2

      I did build a Honda once. It was a great car. I actually do miss it after 8 years of $3.50 gas prices, yes I do... I couldn't bond with the Honda performance factor. No offense to Honda owners anywhere... I just wasn't willing to do all the block sleeving and girdle work to stiffen up an aluminum block with a floating water jacket. It cost so much more to achieve the same result. I made a video about it called "Jafro's Honda Civic Confession".

  • @andregross7420
    @andregross7420 10 ปีที่แล้ว +1

    Jafro, using a dial indicator with a round tip on a thread is a bad idea. You can unscrew the tip, than have the flat end to use instead of the round tip.
    I know you acknowledged this in the video about the round tip on threads but I thought I'd just point this out.

  • @robertmeyer8221
    @robertmeyer8221 9 ปีที่แล้ว

    Great job on the videos. I just discovered your channel and I am making my way through them all. It is all very good stuff worth my time. I do have a couple of concerns I thought I would pass along. First I caution you against side loading the grinding stones on your bench grinder. Only the face is designed for grinding. It can come apart and fatally injure you. I am sure TH-cam is full of horrific videos detailing the aftermath. Second, do not use your bench grinder for aluminum. The stone is not designed for aluminum and can load up, become unbalanced and come apart, again fatally injuring you.

    Seriously hungry for more, i feel ive watched every single video bar a few car shows and track clips. Dont make us wait another month for 206 haha I rebuilt my nissan patrol l28 with the service manual and your guidance. I was also lucky enough to aquire a mitsa magna tf and was pleasantly surprised to find I have the same engine youve been show casing. Its a 4g64 16v, I havent started tearing into it but I feel pretty confident now. It cant be too far off from the 63, right? :p thanks for putting so much time, effort and money into these videos

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว

      Oh wow! You got the Galant Wagon. It's mostly the same... Just a different timing belt and a different bore and stroke... but yes! You will find that all of this stuff applies. You should still follow the Magna's service manual for spec, or the overhaul section of the Mitsubishi shop manual for the 2.4L if you can't find the Magna manual.

      ***** yea brother in aussie we call em magnas.. I wish I had a good website or forum to gather knowledge and learn which mitsas I can use as doner cars. I like the 4g64, for a 4 cylinder it goes like stink I just wanna get more haha it uses slight oil, but not enough to produce smoke. also removing the oil cap you can feel massive blowby which is taking its toll on the spark well seals.. good times!!

    YEA!! Video!! Great work as usual. I am not sure what is more impressive, that you take the time to voice over and edit down that many hours of footage or that you actually trained a cat. The fact that you somehow did both... so how long have you been single?

      Hahah... 42 years and 2 weeks.
      Caboose was an easy one, and Manxes usually are because of the mutant gene. But I've got a female manx that's dumber than a bag of hammers, so that doesn't seem to help them every time. She hides all day, and that's why you haven't seen her. She's the only one I've ever had that I've never been able to train.
      I learned training a cat is more about training ME to figure out what they want rather than me actually teaching them anything. If the cat is easy to read, it's easy. I just mess with them constantly before giving them what they want and it makes them forget they're cats. Every time they cooperate, I give them what they want. They already know how to do these tricks instinctively if you keep them happy, and usually don't realize they're participating in a game once they trust you.

    I don't envy DOHC engines.
    That's a lot of work.

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว

      One thing they offer that you can't get with a pushrod motor is adjustable Lobe Separation Angles. You can still adjust the LSA on a pushrod motor, but the amount of work involved is VERY different. You know what I'm sayin'... ;P Yes, I know you do. :) You have to know a LOT more about valve timing in order to get a pushrod motor right.

    • @3rdGenGuy

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว

      Oh yeah, I know. They are easy to install. It's because the intake and exhaust profiles are all on the same stick.
      With DOHC, you get infinite control of how far apart you want your cam centerline specs, and you can do it with both cams installed. The distance between centerlines is a value called Lobe Separation Angle. Pushrod motors have LSA built into the bump stick, so it's a static value that you can't change without replacing the cam. In other words, on a pushrod motor, you have to know and have calculated the perfect cam grind in order to get the most out of your build prior to purchasing your camshaft because the overlap and lobe separation angle values are built in to the cam and can not be changed. They're easier to install, but they're harder to get perfect because it requires a greater understanding of how valve timing events work.
      On a DOHC, you can turn one cam independently of the other and dial in the overlap and lobe separation angles just where you need them for maximum performance. So you can purchase a camshaft that's close to what you want, and make it perfect during install. Overlap will determine how lumpy the idle is, and LSA will affect how it behaves across the whole power band.
      You bring up extremely valid points, but we'll expand more on valve timing in the next video. DOHC is more troublesome to install, but offers far more tuning capability. I hope this makes sense. ;)

    • @RLHubner

      Hey Jafro, I have a project I'm preparing to get started with. It's a 1.4 liter OHC Opel engine, and it's currently installed on my little bite sized truck.
      This engine comes stock with a 12.3 compression ratio, so I don't plan on changing stroke or bore. I also want to keep it naturally aspirated, my main goal is to improve efficiency and/or power-to-weight ratio without changing the capacity.
      I'm wondering if you have any advice on how a valve/porting job on a 2 valve per cylinder OHC differs, if at all, from a 4 valve per cylinder DOHC.

    • @Jafromobile
      @Jafromobile  10 ปีที่แล้ว +2

      Thank you for that, and I'll do my best to type my longest answer ever.
      My heroes are Henry Ford, Thomas Edison, and Harvey S. Firestone. Not so much for building an automotive empire that saved the US Economy and who all helped pull us out of the Great Depression... but for their inspiration and belief in people, and in ideas. It wasn't their products that changed a nation. It was how they all looked out for their fellow man, and in very different ways. Look up some of their quotes. No, I'm serious. Look them up. They empowered the poor and middle class. It wasn't politically motivated, either. They were just a couple of industrial capitalists with big ideas who were best friends, and who invested in people. They rewarded all those willing to do hard work, and thought BIG! THAT is what made them brilliant businessmen and what ultimately lead to their gigantic successes.
      Harvey figured out how to mass produce rubber tires and market them to the world... SO WE COULD RACE. As a pet project, he bankrolled the founding of Alcoholics Anonymous which has saved or prolonged the lives of hundreds of millions of people from suffering since 1935, and he's the reason its headquarters are in Akron, OH on donated property. He did it as a thank-you because the 2 guys with the _IDEA_ of a 12-step program delivered him a sober son. True story, look up "Bud Firestone" and "The Oxford Group Connection". Harvey wanted to promote Dr. Bob and Bill W.'s IDEA which at the time was the only solution anyone had ever developed that could deal with alcoholism. Doctors during that era were helpless and offered no solutions. People *often* died from detoxification treatments at the hands of medical professionals, so there was never prior to then, ANY hope for people who suffered from addiction. AA's 12 step program is still to this day mankind's most successful means ever developed that treats any addiction to anything. Every kind of addiction uses the same 12 step program. Modern doctors still rely on it because it still has the highest success rate. It has helped hundreds of millions of people world-wide with alcoholism, drug abuse, gambling, sex addiction and even enabling since it was first promoted. I'd call that a successful idea. There are several other reasons I respect this guy that I will leave un-spoken that have nothing to do with tires or AA.
      Ford was the first industrialist to let black people work in manufacturing. Of course it was always the right thing to do for humanity, and Ford did a great job despite the already-existing racial tension and the ultra-left leaning manufacturing unions who would stop at nothing to keep American society segregated. Things really boiled to a head in the early '40's when WW II manufacturing moved there to be closer to the auto industry's supply chain and materials, bringing a massive influx of black people looking for jobs. The armories looked to Henry Ford as an example to create desegregated factories, but they implemented it ALL WRONG because they didn't treat their workers equally like Ford did. After all the race riots, bloodshed and putting out all the fires that resulted from their un-kept promises about working conditions and housing, it set an example that became a turning point for America. Those incidents were the beginning of the civil rights movement that lead to equality for all of us. Henry Ford was a civil rights pioneer for all people, and one that he is seldom recognized for. Probably a few hurt feelings over that whole Detroit burning thing... It's strange how history gets re-written to demonize or ignore rich white capitalists who made a difference to people of color, isn't it?
      Edison helped Ford figure out how to wire up his inventions and turn them into useful products that anyone with a job could afford. That empowered working people from any and every social class to RACE, BECAUSE THAT'S WHAT CARS ARE SUPPOSED TO REALLY BE MADE FOR. Naturally, I'd like a guy like that. He also helped light up a nation in [all of] his spare time. That deserves some merit as well. If you happen to ever make it to clearwater florida, visit the Edison museum and spend some time thinking about the significance of the 1929 Model A that sits in the driveway... what really went into making that thing even possible... and then what resulted from it. Millions of those things were built, but that one... which was a gift to Edison... THAT one is the most symbolic American car on our soil. A close runner-up is the first Shelby Cobra prototype, but to me, that Model A is beautiful.
      These three industrialists were HUGE philanthropists who changed the world. They were friends and neighbors who cared about PEOPLE. A whole lot of $#!†'s changed here over the past 90 years, and right now, more than ever, the world could use a few more people like them. I wish these heroes would step up to the plate because aside from our men and women in uniform, America is all out of them right now. I'd settle for thousands of hero apprentices rather than one big one.
      I don't know what it is exactly that you're studying? I will say this, though... Don't let what you're studying influence where life takes you. Figure out what you want to do first, and then study where you will develop the best IDEAS and help you make connections necessary to get you where you want to be. A quality education is useless without ideas. If you _already_ possess creative thought, then you already have everything it takes to be successful in life. ALL the education will ever do is open doors for you, and to help you develop and reach your full potential. An education is completely worthless without ideas. *Feed your creative process.*
      I have an un-finished Bachelor of Science in chemical engineering. How that turned into 10 years of advertising experience, a senior Information Systems technology career for higher education, and wrenching on turbo imports on TH-cam in my spare time is beyond my comprehension?... but here I am!
      I'm pretty sure that this is not the answer you were expecting. ;)

    • @ClickoZen
      @ClickoZen 10 ปีที่แล้ว +1

      The way you work and write is an example. Best regards Jafro.

      ***** Hey Jafro, let me just say that I am also very thankful for all the hard work you do on putting these glorious pieces of engineering back on the road, as well as offering us a very detailed close-up of the whole process.
      I am in a similar boat as ClickZen here. However, I do know where and what I'm going to study. I'm starting a bachelor's degree in Motorsport Technology in England this year, and I'm very excited and enthused for starting this course. Hopefully I'll learn relevant stuff which will allow me to go on and do similar work as you, applying all that knowledge and using my two hands to make ordinary cars into extraordinary racing beasts. To be someone called Frank, the sheer amount of information and all the details in some of your videos are at times intimidating. Just earlier I was in the garage checking the timing belt on my non turbo 4g63 2G Eclipse (European version), and I thought to myself "I aughtta change that soon". However having just watched your video (and a few other retro vids on how to change timing belts on 1Gs), along with the fact that I have absolutely 0 proper tools and previous experience to do this, I don't think I'll be changing my own belt anytime soon.
      So far the only things I've done are change two footwell light bulbs, tighten my E-brake, fix my rear hatch keylock and paint the lettering on my tires. All those were really fun to do, though, so I'm pretty happy with my progress. Hopefully I can get into a shop after I graduate and start learning some more technical know-how, as I am very eager to start wrenching on this. I'll try to preserve my DSM in the meanwhile, as I have great plans for it, albeit with it's lack of a turbo and AWD.
      Aaaand it seems I've also popped a fairly long response. I do like reading long posts, haha! Well that's pretty much it. I would like to hear what you think about all this, if you have the spare time to post back.
      Keep up the good work, you really seem to enjoy it, as I sure as hell do!

    Would you say that a resurface job on the block and head would be enough change to suggest using a new set of dowel pins?

I had 3 smart friends with limited time, or kids, or both... and every tool I could find to measure lift was made for OHV v8's. lol. The forum posts had how-to's for making tools, but I did mine a little differently here. Thanks Omar!

  • @kick2299
    @kick2299 9 ปีที่แล้ว

    Is this something i need to worry about if I'm replacing a cylinder head with an all stock, re-manufactured cylinder head? I don't have adjustable cams or anything like that, (its actually CVVT).
    I'm replacing the cylinder head because the timing belt went out, while going down the highway. I purchased a remanufactured head on ebay, which is supposed to be all ready to go. Including valve clearance if all stock set up?
    I love you narrations and explanations by the way. :) I never realized how much work went into building an engine.

    • @Jafromobile
      @Jafromobile  9 ปีที่แล้ว

      +joel reindel As long as your build is an all-stock daily driver, you should be fine. The only tricky thing is on some variable valve timing engines, the cams may have some kind of hydraulic control to adjust the valve timing that can make re-assembly a royal pain in the ass. Most modern designs aren't bad, but engines like the 4-banger in the Ford Probe and the Mercury Mistake... I mean Mistique... have a stupid intake cam gear that makes timing them nearly impossible because it rotates almost 15° in either direction, and the cams don't have dowel pins to help you line it up at true TDC. On that particular POS engine, if you don't get the cam within 3° total of zero... meaning 1.5° in either direction, the ignition won't fire. I doubt your re-manufactured head or engine is as tedious as this, or that whatever work was done to it would affect your cam timing enough to make it un-driveable... but barring that on a stock build, it should be completely fine.

    • @kick2299
      @kick2299 9 ปีที่แล้ว

      I was thinking your answer would sound something like that. All stock daily driver it is.
      It is a 2008 Hyundai Accent. The CVVT device is a real sinch. It bolts on to the end of the exhaust cam, and is hydraulically fed through a hole in that cam. So its bolt and go.
      Thanks for the reply. I appreciate it.

Anyway I'm about to hone the block since measuring the bores and the largest spec was 3.350 so hone for now and standard wiseco piston rings on stock pistons.. Glad I got this info here though... It's priceless seeing all this done on the ol' 4g63..
    God bless ya brother.. And please let me know the headgasket you're using since I'm getting ready to replace all the old bells and whistles on this girl.. recommend the felpro kit that advance sells for 90$ including the felpro composite gasket?

      Don't worry, valve timing gets explained better in the videos that follow. This video will make more sense afterwards if you still have grey areas. I think I'm going to make some animations to illustrate my points in it. If you had to set the valve timing on your own engine, you'd figure this out in a heartbeat. ;)
