CRANKWALKED? 7-bolt teardown 1080HD

Now this is a story all about how My bearings got flipped-turned upside down And I'd like to take a minute just sit right there And tell you how I used to mix and burn my gas and my air. In RVA suburbs born and raised On the dragstrip is where I spent most of my days Chillin out, maxin, relaxing all cool, 'n all shooting some BS outside with my tools When a couple of guys who were up to no good Started running races in my neighborhood I heard one little knock and my rods got scared And said "You put it in the garage until you figure out where..." I Begged and pleaded that it not be that way, But it didn't want to start and run another day. I kissed it goodbye, because the motor punched its ticket I got out my camera, said "I might as well kick it." Crankwalk yo this is bad Drinking metal shavings from an oil pan. Is this what the rumor of crankwalk is like? Hmm this won't be alright But wait I heard knocking, grinding and all that Is this the type of failure that should happen to this cool cat? I don't think so, I'll see when I get there I hope they're prepared for this video I share. Well I pulled all the bolts and when I came out There were chunks in my fluids in the pan and they drained out I aint all depressed cause I seen this before. I got my books and my wrench and we'll do it once more. I sprang into action like lightning disassembled I whistled while I worked and my hands never trembled If anything you could say that this bling is rare, and when I saw what broke I stained my underwear. I turned off the air compressor 'bout 7 or 8 And I yelled to crankcase "Yo holmes, smell ya later" I looked at my internals they were finally there To sit on my workbench and stink up the air. Audio track by RojoDelChocolate. Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag passes, a half dozen Dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use.

7-Bolt Shortblock Failure - Full Diagnosis
If you are your own mechanic, there is no more important character trait worthy of development than the ability to own your mistakes. That's where the line is drawn between good mechanics and bad mechanics. It's not the failures but how they deal with them that measures their ability. In short, it's not easy to admit you did something wrong or were negligent. But if you don't own it and talk about it, it doesn't get fixed, and nothing positive can come from it. It was my quest to overcome my clutch issue that lead to the creation of a video. That video is the textbook perfect guide for how to correctly install a DSM transmission. https://www.youtube.com/watch?v=6bE_9sWtnSY&list=PL4B97C16D423317DD Crankwalk as described is caused by a casting defect. This was not a defect. This was preventable. A lot of people would find something like this and not tell anyone out of embarrassment. I'm not ashamed. It's my fault. I got good use out of this engine and it was tough enough to make it 48K miles since the last rebuild despite my abuse. I'm here to tell you if you bought a used car that's had its clutch replaced, or if you ever pay someone else to do it... make sure it has this bolt. It's stashed away between the starter and the transfer case, so it's hard to see. Make sure all of your bell housing bolts are torqued properly because fastener problems can destroy your shortblock, clutch and transmission. If your car fails because of a mis-aligned transmission, you have no reason to blame crankwalk. It wasn't until I bought my next AWD car that I discovered there was a smaller bolt on the other side of the block. I destroyed 3 transmissions in the GSX first. With the damage already done to my crankshaft, I then lost a shortblock. It's an ounce of prevention that's worth metric tons on your bank account. Grade 10 M8x60 bell housing bolt = MD706012. It gets 22-25'lbs of torque. Owning my mistake permits me to learn from it through con$equence$, and never repeat it. What good would it have done anyone else for me to learn this lesson and not share it? That's why I'm providing this video to all of you. Sharing it can perhaps help someone else avoid this costly mistake. This is the final chapter for my 7-bolt, and this book is going back on the shelf. Here are some valuable resources if you're trying to read bearing damage: http://www.enginebuildermag.com/Article/5150/csi_engine_bearings_when_good_ bearings_go_bad.aspx http://catalog.mahleclevite.com/bearing/ http://www.studebaker-info.org/tech/Bearings/CL77-3-402.pdf And of course, now that I've covered the complete oil system, transmission and driveshaft series of videos, you now have all the tools necessary to ensure your 4g63 lasts a very long time. Whether the casting defect exists?... or it's all caused by a bolt, or the harmonics, or whatever... Sure, crankwalk exists and it's horrible. But with the small amount of movement required for your crankshaft before it contacts the block isn't far enough to make your clutch drop to the floor when you turn. You'd be hearing woodpeckers and jackhammers on the crank long before that clutch pedal would fall to the floor. Some people are going to hate on me for saying that. That's fine. I believe all of the people who experienced the clutch pedal issues had fastener problems on their bell housing. DSMs get a bad reputation for this but we can change that. Crankwalk is never the cause of your engine failure. Crankwalk is always a symptom of the real problem. It's your disease that makes you deny it's your fault. You've got the 'itis. DSM-itis. Whenever you dig deeper, you'll discover what applied all of those thrust loads to your crankshaft to begin with, and it's not going to be a casting defect that moves your crank .101". Mine only went .014", but all of the same parts failed. PLEASE tell me in the comments if you find this bolt is missing from your car.





Cylinder Head 205 - Degree DOHC Camshafts
This video is all about establishing your valve timing baseline, and adjusting your camshafts to the manufacturer's spec. It's only ONE of several steps that should be performed when you're assembling your engine on an engine stand. Establishing these conditions with accuracy while your engine installed in the car is a near-impossibility, and the reason why... is demonstrated in this video. There are several challenges to overcome when performing these procedures on a 4gxx series Mitsubishi engine, and they're all defeated here. The cylinder head used in this video is a J1 spec '92 Hyundai Elantra small-combustion chamber head which has had several valve jobs and has been resurfaced multiple times by budget engine remanufacturers who didn't care about quality control, as well as performance shops who do. It has had no less than .040" removed from the head gasket surface, the valves are recessed because of all the valve jobs performed, and at some point when it was cut, it wasn't level. Removing material from the deck surface will change the installed camshaft centerline, and that will change your engine's valve timing events even if all other parts remain the same. I would claim this is a multi-part video except that I've got the videos broken up by topic already, and this one is all about setting your cams to the manufacturer's specification. It is not the end of testing that will be performed with these tools. The basics concerning the process and tool fabrication are covered here. Further discussion on this topic concerning the effects of advancing or retarding camshafts from spec, and for checking your valve clearance will be in the videos that follow. I had to end this video after the manufacturer's spec was achieved to make it easier to digest, and because it would have created a video greater than one hour in length despite the break-neck speeds that things happen here on Jafromobile. Where your cams are set determine how the swept volume of the combustion chamber gets used. The information on the manufacturer's spec sheet is their recommendation for baseline settings that will help you get the most out of those camshafts. Whether or not your engine can operate with those specifications without additional hardware or without causing a catastrophic failure will be expanded upon in Cylinder Head 206. The next video should be used as a companion to this video because establishing the manufacturer's baseline is not the end of the assembly or testing process. It's only half the battle. Should you be lucky enough to find your combination of parts allow your camshafts to fit and requires no additional adjustment after assembly, the steps in this video and in Cylinder Head 206 should still be performed if you are doing the assembly yourself. Failure to inspect these variables may lead to a tuning nightmare once the engine is back in the car, hard starts, or worse... bent valves and damaged wrist pins. Making these tools and performing these steps will give you the peace of mind to know with certainty that your engine is operating safely at its peak performance.





Block Preparation Part 1
Preparation for powder coating and Glyptal application. Audio track is an original performance by Rojo Del Chocolate. My block is being powder coated rather than painted. It's just something I do. The GSX had it on the last block so it's getting it again. Since the tools are so similar and the mess is the same, I'm going ahead and preparing it for the Glyptal application as well. These 2 coatings will require being baked separately. The powder coating is baked on at a hotter temperature than the Glyptal, so it's going first. The surface preparation instructions for Glyptal is as follows: Surface to be painted should be dry and free from dirt, wax, grease, rust and oil. Remove all grease and oil by washing surface with mineral spirits. Wipe or scrape off all loose dirt, rust or scale. The last sentence is what's covered in this video. The 2nd sentence happens next (although it's already degreased), and I'll get it back from powder coat with it in the state described in sentence #1 completed. If following these instructions to the letter of the law. Second and third opinions in... the main journal is fine. You'll notice that I didn't coat the main caps, or "suitcase handles". I'm not going to. You bang around on these installing and removing them, and I don't want to risk chipping them once they're coated. They're below the windage area, and there will also be an un-coated main bearing girdle down there. This video covered 25 hours of actual work. Yes, I kept changing into the same filthy clothes every shoot because I wanted it to look consistent. You have to take your time doing this kind of work, and be VERY VERY CAREFUL! If for some reason you're crazy enough to attempt what I do in this video, you do so at your own risk. This is an elective treatment that I've never done, but I am by no means the first person to do it. I'm learning about it just like the rest of you.

4g63 Block Oil Gallery Mod
This modification is intended to improve your 4g series engine's oil delivery. People frequently discover large chunks of flash in their engine's main oil gallery. It's because the galleries are part of the cast, they're not machined into the block. There is also a very rough sharp edge where the main oil gallery is bored into the block, and oil must make a slightly greater-than 90° turn in order to begin its course to the parts it lubricates. Both of these conditions cause turbulence in the oil flow. My goal in this video is to eliminate as much of that as I can. This is a cheap and easy modification if you have the tools, and the patience. Any engine with cast-in oil galleries could probably benefit from this. Be careful not to cut into the high pressure oil gallery or else you will circulate un-filtered oil to the #1 main, oil pump, and rear balance shaft. You will also deprive the rest of the engine the oil pressure it needs to operate. So in short, punch a hole in that and it's trash. I did this my way, everyone may choose to do this a different way. I just wanted to make this video to raise awareness. Also, there's a great thread on DSMtuners about this. Pictures and everything. Written by a machinist and friend of the DSM community. Go give him some reps because he's posted a lot of great info about the DSM oil system over the years. http://www.dsmtuners.com/forums/articles-engine-fuel/452546-4g63-block-oili ng-mod.html





New Year's Eve Hyundai Teardown
It goes like this. One of the best friends I've ever had built this car from junk parts. He said it best, "it was built from literally a box of scraps". It ran an 13.2 in the quarter mile using no aftermarket performance parts of any kind. That quarter mile time was limited by traction. I know this car had more in it, but I never managed to get it to stick before encountering this. More on this build... The proper bolts were not always available, but the builder knows isht from Shinola. Even though this engine defies all engineering logic from Mitsubishi, the builder knew what would work and what would not. Budget was of the most primary of his concerns, and it shows at every turn, and it's what brought us to the kind of failure we find in this video. I asked him what bearings he used. He said, "...the least expensive ones I could find. Picture Aluglides. Now picture generic Aluglides. I paid half-as-much for those bearings as I would for generic Aluglides. Bolt too long? Put a nut on it and shorten it. Oil pan too close to the pickup? Hammer a big dent in it to make clearance for it. Wrong water pipe? Put a brass hardware store tee in the line to tap a turbo coolant feed. Forget buying ARP's, this is an all-standard re-used factory fastenere'd no-oil-squirter .030"-overbore 6-bolt with the cut-off balance shaft mod. It's using a small combustion chamber head off of a 1.6L Mirage with a 2.0L non-turbo block. The plug wires are used. The radiator hoses were used. Everything but the head gasket came from a junk car. The FWD turbo gearbox is from my 150,000 mile old Plymouth Laser that donated the block to the Colt. This is one of the most amusing cars I've ever wrapped my fingers around because of these kinds of character-building attributes. Nevermind that the chassis has less than 70,000 miles on it (not bad for a '92), it's just that it's built without using any new parts. Parts were substituted when they were not available, and it's ridiculously powerful. Thank you Jamie. You discovered your answer. I'm happy to help. I'll be changing some things like the oil pan bolts, bearing quality, some of the plumbing and fixing a few wiring harness problems, but I'm not changing anything else if I can avoid it. This car was never intended to have anything upgraded to deliver raw power, and I'll do my best to keep it that way, replacing and restoring what failed so that we can keep pushing these generic non-turbo .030" over pistons to the limit. Apparently, 24 PSI from a 14b is not enough. In the meantime, my diagnosis is that excessive oil pressure lead to the breakdown of the #1 bearing. After all, it's the 1st bearing in-line in the oil system on the main gallery. It's the most isolated from clutch harmonics, yet it was the one that spun. The #1 bearing supplies the oil pump. The teardrop on the head is nearly gone from head resurfacing, and this is a no-balance-shaft no-oil-squirter block. I think high oil pressure is why it falls on its face above 6000 rpms. There's a restriction upstream from the lifters and they deflate at high RPMs, losing lift. I'll fix it. I've got the parts.





4g63 Balance Shaft Elimination - bearing modification
This is the first part of a two part series about balance shaft elimination on 4g series engines. This video details the bearings, the other video will cover the front case modifications. I've already got a low-def video of the front case mods, and I plan to re-shoot that one in HD when I'm in the assembly phase. It's linked in the video. The balance shafts are designed to cancel out harmonic vibrations caused by combustion and the spinning rotating assembly. They may offer a greater degree of comfort to the driver and passengers, but with that comfort comes a price. Often, when a 4g63 timing belt gives up, it's because the balance shaft belt breaks or comes loose and takes the timing belt out with it. When that happens, it can total your pistons, valves, damage the crankshaft, wrist pins, timing belt tensioner and crank angle sensor. Basically, it can total your motor. The balance shafts also have a combined weigh over 10 lbs and both are driven off the timing belt making them additional and heavy rotating mass. If you've got a lightweight flywheel but still have balance shafts, you have your priorities mixed up. So here's what you do with the bearings. It's easy. You can do this at home. You CAN do it with the motor in the car, BUT DON'T. You must enjoy punishment to do this like that. The end result will slightly increase your oil pressure, but usually not enough to cause concern unless you have a full-circumference bearing turbo, ball bearing turbo--with your oil feed coming off the oil filter housing. The head feed would be better in that case because it's regulated at 15 PSI.





Blueprint 106 - Cylinder Bore Inspection
We're close to the end of the 100-level series. In this video I show you how to measure the cylinder bores using 2 different tools. I compare the results and illustrate what to look for to determine whether or not your engine is in-spec. The block I'm using is a 6-bolt turbo 4g63 from early '92. It has 150,000 miles and this video also serves as a testimony for the durability of Mitsubishi's cast-iron solid-decked Sirius I engines. This engine will be cut for a new set of pistons, so these measurements are needed to determine what size pistons I need to get. .030" is as far overbored as you should ever take a 4g63. Boring larger than that will take too much off the side clearances between the cylinder walls and result in compromised strength from hot spots. The only time you'll ever need to cut a bigger hole is when an imperfection prevents you from using the pistons you have, or if you're changing to a larger piston. If you cut the block to its service limit, you have no room to fix an imperfection should one develop... so it's best to cut as little as you can get away with. Boring a cylinder .020" over does not significantly increase its displacement.





Boost Leak Testing 202: Hair Spray 1080HD
Why do I know about this? I'm tired of being the one knowing all the weird crap. If everyone knows it, it won't be weird anymore. It will be commonplace. By the time I'm done sealing up all of my own Boost leaks, all of you will also be experts as well. I'm sure most of you would teach me something, too... but you subscribed, so here it comes... something I learned in my travels... Also, thanks Ilya M. I've only heard about it twice in my life. It worked great for the one time I've ever needed it, and I'm a huge fan.
