resurfaced.
lf camshaft-to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurfacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in). resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.

18.Apply liquid gasket to the rubber seal at the eightcorners of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - OO01 or 08718- 0003.
. Check that the mating surfaces are clean and drybefore applying liquid gasket.. Do not installthe parts if 5 minutes or more naveelapsed since applying liquid gasket. Instead,reapply liquid gasket after removing old residue.. After assembly, wait at least 30 minutes beforefilling the engine with oil.
