valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:

If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.

If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

pound.
(e) After hand±lapping, clean the valve and valve seat.
