(7) Apply seal packing to the front bearing cap.

Remove any old packing material (FIPG) and
be careful not to drop any oil on the contact
surfaces of the bearing cap and cylinder
head.
Using a razor blade and gasket scraper, re-
move all the old packing material (FIPG) from
the gasket surfaces and groove.
Thoroughly clean all components to remove
all the loose material.
Using a non±residue solvent, clean both
sealing surfaces.

Apply seal packing to the bearing cap as
shown in the illustration.
Install a nozzle that has been cut to a 1.5 mm
(0.059 in.) opening.
Parts must be assembled within 5 minutes of
application. Otherwise the material must be
removed and reapplied.
Immediately remove the nozzle from the tube
and reinstall cap.
Seal packing: Part No. 08826±00080 or equivalent
NOTICE:
Do not apply seal packing to the front bearing cap grooves.
(8) Install the front bearing cap.
HINT:
Installing the front bearing cap will determine the thrust portion
of the camshaft.
