CAUTION
Excessive sealant can run back into the engine and
cause damage to other components. Allow the
sealant to dry for a minimum of 2 hours before
operating the engine. The plug can come out of the
bore if the sealant is not dry.
Apply a 2-mm [1/16-in] bead of cup plug sealant, Part
Number 3375068, or equivalent, to the outside
circumference of the cup plug and the inside
circumference of the cup plug bore.
NOTE: Do not install a used cup plug. Discard all plugs
after removal.
Install the cup plug with the appropriate cup plug driver.
Reference the Service Products Catalog, Bulletin
3377710.
CAUTION
Do not install the cup plug too deeply. If the cup plug
is not installed straight and flat, it must be replaced
with a new cup plug or engine damage cab result.
The cup plug must be installed with the edge of the cup
plug 0.5 to 1.0 mm [0.020 to 0.040 in] deeper than the
leading chamfer of the bore.
