How to lap valves on a 1995 Eclipse Talon 420a head (non-turbo)

When my 1995 eclipse timing belt broke I knew that there was a 99% chance that the valves were bent in the process. I searched the internet for a good way to replace them, without having much luck. I figured I would try and come up with something myself, I figured I would document the whole process of valve lapping by video...hope this helps you if you are in the same bind as I was!!!

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 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 leak test how to check for bent valves
i did this video to help some of you not get ripped off when buying a motor. i will be doing many videos of how to test parts and what to look for. please email me if you have question or what to learn how to test something else pls52202@yahoo.com or thinkperformancemotorsports@gmail.com

Testing for Leaking/Bent Valves
--Please Read-- :) Some of the best advice I can offer you about fixing your car is to search for an online forum related to your car, or even for your specific engine. If you have a popular car or engine, this can be an amazing tool in diagnosing and fixing cars yourself! -------------------------------------------------------------- Directions 1. Get kerosene, gasoline, or break cleaner. 2. Tilt head on its side, with the ports of the valves you're testing pointing up and exposed. 3. Fill the intake or Exhaust ports with the liquid you chose, make sure to use enough liquid to cover the back of the valve head completely inside the port. 4. Look at the valve surface in the combustion chamber for leakage. (Let it sit for several minutes) 5. If there is a leak, you could have a bent valve or just a bad seal of the valve to the head. You might have to replace the valve, or just use some lapping compound to lap the valve/seat to resurface. 6. Repeat for the other side if you wish. 7. This is a great time to replace valve seals if you have noticed they are worn too much. 8. If you have any questions, please post them here and I'll try to answer them quickly. -------------------------------------------------------------- You just tilt the head on one side or the other depending whether you want to test the intake or Exhaust valves. I'm testing the intake valves in this video. I did this way because I didn't have the leakdown test equipment, but also because I wanted to replace my head gasket anyway. I wouldn't say this is the best way to test initially if you suspect leaking or bent valves because it requires you remove the head. Try just a regular leakdown test first. But if you're taking it off anyway it's pretty nifty and doesn't require the leakdown test tools. There are several methods to do this, this is just the one I chose in my situation.

Fitting new valve guide seals without removing the cylinder head Suzuki Vitara
This is how you can remove and replace valve guide seals with the head still on the engine. Normally you have to have the head off so you can fit the valve spring compressor on to the head of the valve. I had heard of this method but never tried or seen it done before. The only special tool is a piece of string. Watch the video and see the "Essex Red Neck" at work :-)

Cylinder Head 205 - Degree 4g63 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.
