To check the valves for leaks, turn the head upside down with the combustion chambers facing up and pour kerosene into them. If kerosene does not leak out of the combustion chambers within 3 minutes, the valves are sealed.
1. Apply a thin layer of lapping paste to the working chamfer of the valve and insert the valve into the cylinder head.
2. Clamp the valve stem in a lapping fixture.
3. Turn the valve in both directions using the device, periodically pressing the valve against the seat. An external sign of satisfactory lapping is a uniform matte gray color of the working chamfers of the valve and seat.
4. After lapping, thoroughly wipe the valve and seat with a clean cloth, then rinse to remove any remaining lapping paste.
