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.

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.

Cylinder Head 104 - Remove Valves & Springs
Just one of many ways to remove valves from a cylinder head. I haven't seen a valve compressor like this one on YouTube yet. I know it's nobody makes them like this, because this one is a custom hack job specifically for 4g63 heads... but it's extremely effective and easy to use. Since I don't own a valve grinder, valve spring pressure testers (for installed height measurement), or valve seat grinding stones... there are several services I'm unable to perform myself. But since I can get the head disassembled to this state, it would be easier and cheaper for me to have them serviced by someone who does. Valve grinding machine time is cheaper if they don't have to tear down the head. You can lap them in yourself, but if the seat's in really bad shape, it will require attention to allow any of those efforts to be worthwhile. Valve seat grinding if necessary needs to be done with the proper tools, and if the seats must be replaced, then it can get expensive. Usually $20-ish a hole. Sometimes an oversized bore can be cut into a factory seat. I'm ordering a set of valves to see if that's possible.

Valve seal Replacement
Leaking valve seals cause your engine to smoke when you first start it up, and then it usually runs the rest of the day with no smoke. Usually replacing the valve seals will fix the problem. Here's how to do it. Of course other engines may vary to some degree but the basics are the same.

Engine Exterior Cleaning
Cleaning the exterior of my engine block with citrus degreaser and aluminum brush. Scrubbing away the grime can help detect oil leaks but can also make them worse. Cleaning is a double-edge sword. It's always best to bring leaks to the forefront instead of keeping them hidden by grime. My philosophy is not to hide the leaks but to detect and fix them.

EASY, HOW I LAPP & GRIND VALVES. THEY DONT TEACH THIS TRICK IN SCHOOL, ONLY OLDSKOOL.
Automotive technician since 1991 I show how I do a valve grinding job (Lapping Valves) at home using a vacuum hose, drill & compound, don't over think it and don't assume it cant be done. learn how and save money on your project with out taking your cylinder head to the machine shop. Valve guides must be in good shape ( with no significant play or bent Valves before you perform this task, but this procedure works very well if done with care & quality. Go get it! and God bless.





Cylinder Head 101 - Remove Cams Rockers & Lifters
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!





Crankshaft Refurbishing
Many of you have seen this one before. I apologize if bringing it back offends anyone. Domestickilla gave me a crankshaft, and it's a nice one that I want to clean up and use again. You'll be seeing a lot of it and because of this, this video deserves to be here. I fixed what I broke, and this was my experience. In this video Ballos Precision Machine demonstrates magnetic dye penetrant testing, crankshaft polishing and inspecting the balance of a "butchered" 4g63 6-bolt crankshaft.

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.





Replacing valve stem seals in 305 H.O. small block chevy from 1986 Monte Carlo SS
I'm putting the original 305HO back in the Monte after taking the ZZ3 out for my Iroc project. This is mainly to make the car mobile but it may end up tagged with this engine for a while. Previous owner reported that this 305 has over 100k miles on it and has been out of the car since 1997. He said it smoked during startup and sure enough the valve stem seals were worn out. Hopefully this will fix the issue.
