Cylinder Head 105 - Valve Job Basics

Valves not sealing? Valves not bent? This is how you fix that problem. In this video I outline the basic valve job procedure. Cleaning the valves, cleaning the seats, cleaning the combustion chamber and lapping the valves in to make a better seal. Here I cover the process start-to-finish. It's the same exact process for pretty much all non-rotary combustion engines. It takes patience and perseverance to do this job, but anyone can do it. Reference your service manual for measurements and service limits. Everything else that's not in your service manual is in this video. I apologize for not having broken busted crap to work with in this video. It's more beneficial to all of you when bad fortune falls on me because it gets well documented, and many people watching these videos are looking for answers. If you have bent valves, you will discover it quickly once you chuck one up in the drill. You'll see the face of the valve wobble around while it spins. You'll see evidence of this damage on the valve seat. If it's bad, you may see damage on the valve guides in the form of cracks or missing pieces where the valve guides protrude through the head ports. Give all that stuff a good visual inspection. ...and if you doubt yourself, never hesitate to get a second opinion or consult a machine shop. They will have access to expensive tools that you wont find in your average gearhead's garage.

Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might perform. If the 100 series videos didn't help you identify and correct a problem with your cylinder head, then this is the next step. This video is brought to you with permission from my machinist in full 1080HD, and covers cleaning up the head inside and out, preparation and setting up a radius cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of actual work in under 30 minutes. There's nothing like this anywhere else on YouTube. THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional explanation and execution of a job excellently-done, and un-precedented access to your facilities. A valve job is done by re-grinding or replacing valves, and then having new seats cut to match the faces of the valves you're using. There are several different machines that might be utilized to achieve this result, but the process is the same no matter how it's done. There are seat cutters that utilize cutting stones. There are valve seat cutters with 3 separate angles installed 120° out-of-phase, and there are single cutters with all 3 angles (radius cutter) that cut with one blade in one pass. The machine demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out of production) produces a gradual curved seat that's superior to the shape of a traditional 3-angle seat. While a radius cutter does contain the 30, 45 and 60 degree angles, it does so without leaving any sharp edges between their faces. My valve selection includes Supertech 1mm oversized nitride-coated stainless steel undercut and back-cut intake valves, and 1mm oversized Inconel back-cut Exhaust valves. Inconel is a high-temperature alloy utilized in marine and forced-induction performance engines that can handle more abuse than steel can without melting. The other characteristics of the valves which are discussed typically yield bigger gains in airflow than simply using a bigger hole and a bigger valve. Why I did this to a perfectly-good cylinder head: I changed cams. Because the valves were previously recessed during another valve job 9 years ago, my valve installed height was increased and this raised the operating positions of my rocker arms. My new camshaft selection dictates using the stock valve install height. The only solutions to this valve install height problem are to either replace the valve seats, or install oversized valves. I opted for the latter.

Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra small-combustion-chamber head. Thats what it is. It's a J1 Elantra cylinder head. Good luck finding another one like it. (read more)... In Cylinder Head 106 I talked about the mainstream porting theories as they are discussed. We looked at a cylinder head that I have thousands of dollars of professional work performed on, and a bone-stock second-generation head that I didn't port. In this video I just might do something you haven't seen done before. For some, that may be uncomfortable. The port and polish job I perform here is what I think will work best for my current build. This is not an extreme killer port job. What will be different here is where port textures are concerned, I will be following the advice of a reputable source that will remain un-named. You're free to port yours differently than I do in this video, and I give you that out, around the 20 minute marker. The Hyundai is far from being an ultimate-performance build. It's a $400 box of scraps with nothing but time invested. It's perfect for this video. My finished product WILL be an improvement over what I had. I don't yet have access to a flow bench. I still have an achievement to un-lock. As far as you should be concerned with the techniques I employ... without flow numbers there is no evidence of what this will do, but we will gather lots of info from dynp sessions and drag strip time slips. If I could test it on a flow bench, I would. There are MANY, and when I say many, I mean thousands of flame war mongering pirates floating around on rough seas with a hair trigger cannon finger itching to fire if you port a head any differently than what the herd mentality says to do while porting a cylinder head. I cover the herd mentality because it has merit. It's been tested. Tried and true. But I don't follow it to the letter of the law. I'm definitely not here to de-bunk it. I would port a cylinder head differently for each build based on how that engine was used. There's an extremely valid reason why relating to air speed. It's not the texture of a port that maximizes the effect of fuel atomization, but the velocity of the air running through an x or y sized valve. The driving factor in this is the piston speed. I'm not going to give you the technical information, but will refer you to information about the Lovell factor. There's a better description of this in the links below, and even a calculator to help you find your engine's sweet spot. Why the Lovell factor is important: https://www.highpowermedia.com/blog/3346/the-effect-of-valve-size Lovell gas factor calculator: http://www.rbracing-rsr.com/lovellgascalc.html Only people who have flow testing equipment know for sure what really works and have the capability to produce a perfectly-matched port job for the ultimate performance build. Those guys know the definition of ultimate, and THEY are floating below the water Aegis-class submarines ready to blow your comment up if you don't know what you're talking about. They don't care if you're an armchair mechanic or a herd of pirates. I will say, they're zoomed in pretty close on me right now, and I'm expecting to take a few hits. My work will be tested based on Dyno and drag strip performance, and the results will be posted here. Fortunately, those kinds of videos are a WHOLE LOT EASIER TO MAKE!!!





How To Remove and Replace Valves in a Cylinder Head -EricTheCarGuy
If you need to remove a valve from a cylinder head either to replace the valve or replace the valve seals, this video will help you do that. You can also do this process while the cylinder head is still fastened to the engine block with some tools. To do that, put the piston at TDC compression stroke and make sure both valves are closed. You can then run compressed air into the cylinder to hold the valves in place as you compress the valve springs. I often use my compression tester hose to do this. You need to remove the schrader valve first before you attempt this, if not, air will not flow into the cylinder. You can also use a piece of rope or equivalent to keep the valves from dropping into the cylinder while you work. This method works well if you're just replacing the valve seals. You won't be able to use the large spring compressor however. You'll have to use the Lisle or some other type of compressor do manage that task. Here's some useful links for you. Tools. Large Spring Compressor: http://www.jbtoolsales.com/gearwrench-383d-valve-spring-compressor/#oid=100 2_1 Lisle Spring Compressor Tool: http://www.jbtoolsales.com/lisle-36050-valve-keeper-remover-and-installer-k it/#oid=1002_1 I had a heck of a time trying to find the Honda special tool and was not able to provide a link for you. Sorry about that. The Lisle tool will work just fine, OR I've seen some home made versions of that type of extension that looked like they'd work pretty well. Related videos.

Hyundai Elantra 4g63 Shortblock Assembly
HOLD ON TIGHT! HERE WE GO! We begin the blueprint and assembly on my 1992 Hyundai Elantra's bastardized 4g63. The parts used in this are from a mash of different brands and models outside of the typical 2.0L 4g63, but the specs and standards I am following for its assembly are for the 2.0L DOHC. If you want to follow along in your service manual to verify what I've done here in this video, the processes we cover here detail pages 11C-95 through 11C-105 of the 1g Overhaul manual. I would prefer you not rip them from the binding and throw them away, relying only on this video for instruction... but rather use this video as a motivational guide, and as a demonstration of the techniques involved in those sections. You gotta do the cooking by the book. I never had any intention of making instructional videos on this particular car, but after it blew up I slowly realized it's actually a better case study for how a 4g63 ticks than anything else in my driveway. There are several reasons for this. One being that it's a mix of parts that shouldn't be bolted together, and the other is that many of you watching my videos aren't trying to build a 600hp engine out of aftermarket parts. You're trying to put back together what used to be your daily driver. This car covers those bases. Don't think for a second I won't go through this same trouble and level of detail for the GSX. I will. When I do, having this information in this video will give you a better understanding on how and why I do things the way I do when I get there. This was the shortest I could condense this video. I've never uploaded a video this long, and I hope I never have to do it again. It took a month to create on cutting-edge equipment, 16 hours to export, and 9 hours for YouTube to process. My script for the voiceover is 6 times longer than the whole script for the movie Pootie Tang. 6 times. Longer. Than a Hollywood movie.





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.

Going through a 4g63 Cylinder Head? You're on the right channel. I don't know how many parts there will be to this series, I suppose it could go on forever... We all have different ways of doing it, and I'm going to show you mine. This video won't put a dent in most people's grey matter outside of entertainment value... but I tried to keep it fun. I'd like to leave at least a small dent. But no music in these because they're going to cover a lot of ground and fast. I'm not doing anything difficult. This part of this job really isn't. Most everybody pays someone else to do the complicated stuff for them, and those people do it every day so it's still easy unless you earn your money to pay for it from difficult and degrading means. But this video's about getting started. There's some safety and organization tips to be aware of before diving in. Stuff that could help people whether or not they even own a Mitsubishi. Everything else is in the videos!

How to Reseat / Lap Valves (Basic Valve Job)
In this video i'm explaining how to reseat or lap valves in a flathead or overhead valve engine. Also can be called a valve job, but this is not a complete valve job. I also used to much valve grinding compound, it does not require a whole lot. Usually when a engine needs this done is when a engine has low compression that is found to be leaking around the valves, or sometimes a engine will backfire do to the valves not closing completely/properly. Thanks for watching.
