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

noticed their welds were already cracked.

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.
