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.

Well this was a fun one to make. I believe I covered everything but if you
feel I haven't please let me know in the comments below as well as any tips
you might have to add as well. I'm not trying to make a big deal about
"pound feet" or "foot pounds" I'm just trying to put that out there, the
important thing is that you get the proper torque and get the job done
right in my opinion, what you decide to call it is up to you.

Engine Exterior Cleaning
Cleaning the exterior of my engine block with citrus degreaser and aluminum
brush. Scrubbing away the grime can help detect oil leaks but can also
make them worse. Cleaning is a double-edge sword. It's always best to
bring leaks to the forefront instead of keeping them hidden by grime. My
philosophy is not to hide the leaks but to detect and fix them. Adam

Cylinder Head 102 - Hydro Test Valves
If you noticed a drop in compression on one cylinder, and pouring a cap of
oil through the spark plug holes didn't fix it, then it's likely you
experienced a leaky valve or a burnt valve seat. What this test does is
show you where it was leaking. Typically it takes a valve job to repair,
but this can also occur on a freshly-machined head if any work was done
improperly or out-of-center.
I'm using tap water for the test because both cylinder heads I'm testing
will receive extensive machine work and cleaning before being re-used. If
you were to do this test on a freshly-machined head, you'd want to use
deionized water as it contains none of the salts (sodium, chlorine, etc...)
that would leave deposits and corrode metal parts.

Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might
perform. If the 100 series videos didn't help you identify and correct a
problem with your cylinder head, then this is the next step. This video is
brought to you with permission from my machinist in full 1080HD, and covers
cleaning up the head inside and out, preparation and setting up a radius
cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of
actual work in under 30 minutes. There's nothing like this anywhere else
THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional
explanation and execution of a job excellently-done, and un-precedented
access to your facilities.
A valve job is done by re-grinding or replacing valves, and then having new
seats cut to match the faces of the valves you're using. There are several
different machines that might be utilized to achieve this result, but the
process is the same no matter how it's done. There are seat cutters that
utilize cutting stones. There are valve seat cutters with 3 separate
angles installed 120° out-of-phase, and there are single cutters with all
3 angles (radius cutter) that cut with one blade in one pass. The machine
demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out
of production) produces a gradual curved seat that's superior to the shape
of a traditional 3-angle seat. While a radius cutter does contain the 30,
45 and 60 degree angles, it does so without leaving any sharp edges between
My valve selection includes Supertech 1mm oversized nitride-coated
stainless steel undercut and back-cut intake valves, and 1mm oversized
Inconel back-cut Exhaust valves.
Inconel is a high-temperature alloy utilized in marine and forced-induction
performance engines that can handle more abuse than steel can without
melting. The other characteristics of the valves which are discussed
typically yield bigger gains in airflow than simply using a bigger hole and
a bigger valve.
Why I did this to a perfectly-good cylinder head:
I changed cams. Because the valves were previously recessed during another
valve job 9 years ago, my valve installed height was increased and this
raised the operating positions of my rocker arms. My new camshaft
selection dictates using the stock valve install height. The only
solutions to this valve install height problem are to either replace the
valve seats, or install oversized valves. I opted for the latter.
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.

How to Reseat / Lap Valves (Basic Valve Job)
In this video i'm explaining how to reseat or lap valves in a flathead or
overhead valve engine. Also can be called a valve job, but this is not a
complete valve job. I also used to much valve grinding compound, it does
not require a whole lot. Usually when a engine needs this done is when a
engine has low compression that is found to be leaking around the valves,
or sometimes a engine will backfire do to the valves not closing
completely/properly. Thanks for watching.
