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.
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
2000 Dodge Neon Head and Timing Belt - Part 2
This video includes the clips from part one butinlcudes the SOUND and a
SLIDE SHOW from the project.
Inspection - This is our brother Gregg's Car neon. The water pump seized
and blew the timing belt. We decided to take it all the way down to the
head because there was some question that a valve had bent as well. But
other than a TON of carbon, it turned out to be OK. more at
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)

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.

CRANKWALKED? 7-bolt teardown 1080HD
Audio track by RojoDelChocolate.
Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag
passes, a half dozen Dyno sessions, 4 transmissions,
3 clutches and 10 years of hard all-weather use.
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.
At-home Leaky Valve Test
To check if you have leaky valves, on the removed head, reinstall the
sparkplugs, flip it over and fill with fuel. A bad valve will leaky
quickly. It takes the valve on the right approx 2 minutes to leak all of
the fuel. The one on the left had been tested 3 hrs earlier and was still
full! That's what a good valve should do.
Sorry for the crappy quality but you get the idea.

work,you have to fling valve to valve seat and pull valve,next rote valve
and same work to do.
How to lap your valves 5.4 ford motor , diy valve job
To do this you will need a valve spring compressor, some lapping compound
and the suction cup stick used to rotate the valves. I also show you what
to look for and what a bad valve looks like. Also this is the time to
replace the valve guide seals , just pop the old ones off and push the new
ones on. This was a 5.4 ford but the process transfers to all heads
