17 Inspect the insert for correct installation into the
tapped hole. A correctly installed insert (1) will be
either flush or slightly below flush with the surface of
the base material (2).

18 Any installed insert that restricts or blocks an oil or engine coolant passage (3) will need to have the oil or
engine coolant passage drilled out (4) to the original
size of the oil or engine coolant passage. After drilling
the restriction or blockage, clean out any swarf and
thread the installation driver tool through the insert
again to remove any burrs caused by the drilling of
the oil or engine coolant passage.
