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.
