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!!!

Valve job trick on a Citroen SM / Maserati 3 Liter engine...
A little trick that I learn on the internet some time ago. The lapping tool keeps slipping when the valve has carbon on it or the lapping compound oil get to vacuum cup. It is annoying, isnt it? I hope this helps :o) http://3lmaseratismrebuild.blogspot.com/





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.





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.





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.

Edelbrock RPM Olds 455 Head Porting
The scariest thing I ever did was port a set of new Edelbrock aluminum cylinder heads. My first attempt at porting any cylinder head. I raised the roof .200" and dropped the floor .040". It's best to leave the floor alone or raise it by filling with epoxy. Porting kit by Mondello.

There still alot let in the car we can strech the afr and advance timmig and fine tune the cams also. 10psi 302hp, 20psi 463hp, 30psi 661hp, this was only the 5th pull of the day also lol





6 bolt 4g63 in 2g Eclipse GSX cylinder head removed in under 10 mins
Removing the head of a 4G63 in 10x speed. The project got delayed a few months. After finishing it and cranking it over, Interference in the cylinder was discovered. Shamefully, I admit my mistakes were: 1) Not putting the spark plugs in immediately after installing the head. 2) The bad habit of using my Valve Cover as a parts tray and 3) Putting off the project too long, so I didn't recognize a missing bolt from a custom fabrication. The head needed new valve seats, valves and some welding. Wiseco and the machinist both thought I'd be OK running the piston after smoothing out hot spots, but I ordered a new piston not wanting to risk the deep gouge in it with the high Boost I plan to run. Peace of mind is priceless. The danger in being over confident is sometimes you skip triple checking stuff. I've built that engine at least 5 times and got careless. You can see the port work I did on the head @ http://www.southernutahautos.com under "Tech Tips" and "Beyond Bolt-ons"





How To Perform a Compression Test - EricTheCarGuy
Compression Testing and What You Can Learn From It - EricTheCarGuy Here is a video on performing a compression test on an engine to assess it's mechanical condition. An engines ability to compress air and fuel is directly proportional to it's performance since an engine is nothing more than an air compressor once you take away all the controls. A compression test is a good general test that will give you an idea of the engine's overall health but it does not give specific information on what the problem is should there be one, for that a "leak down test" would be required, here is a link to that video. http://www.youtube.com/watch?v=WgrfT0LFMhc However if you find yourself looking for the source of a performance problem with an engine, this is a great place to start. This test is often overlooked in favor of looking at the fuel or ignition system, I think that's a mistake, if an engine can't perform mechanically no amount of electronics will make that better.

1994 Honda Accord w/ Bent Valve
A video illustrating how your 94 Accord's engine will probably sound if it has a bent valve. Bent valves often happen in cars containing intereference engines, such as this particular model of Honda. They occur most often when the timing belt breaks during operation of the engine. This is an expensive repair, requiring the engine head to be dismanted. To avert this disaster, change your timing belt every 90k miles or sooner. This particular car had about 178k miles on it at the time of the video. There was a bent valve in cylinder 2, and the cylinder lost all compression.

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
