Drive the new guides in from the camshaft side of
the cylinder head to the valve guide height while
the cylinder head is still heated.
Let the cylinder head cool to room temperature, then
ream the new valve guides.
Clean the cylinder head thoroughly to remove any
metal particles after reaming and refacing the valve
seat.
Take care not to tilt or lean the reamer in the
guide while reaming. Otherwise, the valves may
be installed slanted, causing oil leakage from the
stem seal and improper valve seat contact. This
may prevent valve seat refacing .
• Insert the reamer from the combustion chamber
side of the head and always rotate the reamer
clockwise.
