Cylinder Head and Valves
USING AN ARC WELDER
1. Protect the valve guide by installing a cap screw or
dowel in guide to protect from weld spatter.
2. Protect the cylinder head surface with a non-flammable
welder's cloth (A). Apply a thin bead of weld (B)
around ID of valve seat insert. Allow insert to cool and
use a screwdriver (C) or similar tool and carefully pry
insert from bore.
3. After removal of inserts, thoroughly clean area around
valve seat bore and inspect for damage or cracks.
Replace cylinder head as necessary.
