Before Valve Job
Grinding the valve surfaces so they match up with the valve seat. These valves we in good condition, so we clean them up and grind the surfaces. See the before and after shots.
After inspection, disassembly, test for cracks, and hot tank cleaning, we can get to the machining.
Time to recondition the cylinder head surface.
Resurfacing restores Flatness and improves the the surface finish. This allows the head gasket to achieve a proper seal against the engine block preventing the gasket from leaking. A true and flat finish is always desired.
Cutting Valve Seats
We cut a 3-angle valve seat. Cutting the valve seat increases air flow. Cutting proper angles where the seat and valve face mate produces a gas-tight seal.
After the machine work, we assemble it back together.
