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

Just showing your guys how we go about polishing and getting the beautiful
finishes after its all said and done.. this method takes some skill.. some
might say i make it look easy.. at 14000rpm the grinder i use is not a joke
and has hurt people when they dont use it properly.. when the paper unloads
on a long rod it tends to bend the rod at a 90 degree angle and if the user
freaks out and does not hold it away and let it slow down then they end up
with a nice big sliced up arm or mid section.. i myself have bent a few in
my time and lucky for my i have a quick reflex and manage to hold it away
without hurting myself..

!!!!! - DO NOTE VISIT THE WEBSITE AT THE END - !!!!!
I no longer own that website, and it was made into a porn site. I have no
affiliation with it!!!
I wanted to get a baseline Dyno run in before installing my
built motor. This is a completely stock SR20DET with a larger turbo, injectors and supporting mods. Stock cams,
stock head gasket, everything inside is OEM. It also has a very poor tune,
one other reason why it has low numbers. However, I did manage to run an
11.95 @ 114 MPH with this setup so far...
