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!!!
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.
CRANKWALKED? 7-bolt teardown 1080HD
One for the weekend warriors... Audio track by RojoDelChocolate. And that really is Mr. Chocolate himself playing some jungle-action on his drum kit to a bunch of garage band loops. Give the man some props!
Here's the 48,000 mile-old 7-bolt I blew up this summer after over 150 drag passes, a half dozen Dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use. The cleanliness of the crankcase and overall lack of carbon buildup is a testament to the quality of Mobil1 Synthetic oil.
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,
And 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 trying to get depressed cause I got all my spares out.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
The 7-bolt was FRESH with the shine like a mirror
If anything I can say this bling was rare
What I saw inside the engine 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.

661 @ 7600 rpm did not push it that hard on the Dyno saving the rest for the track. GT40r 67mm inducer precision turbo, All we did was make a nice fuel map and add Boost. 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

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 :-)

Compression Testing and What You Can Learn From It - 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.

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.
Recently, I hit the 500 subscriber mark and I'd like to thank all of my subscribers past, present, and hopefully in the future for that. I enjoy making these videos and the fact that you seem to like watching them means a lot to me. So, thanks for subscribing, rating, and commenting, those little contributions make it all worth while.
