Coat new O-ring (18.3 x 3.5 mm) [1] and O-ring (16.3 x
3.5 mm) [2] with engine oil and install them to the oil
pipe joint [3].
Install the oil pipe joint to the cylinder block.
Install a new oil hole gasket [4], two dowel pins [5] and
the crankcase upper cover [6] to the cylinder block with
the seven bolts (6 x 35 mm) [7].
Install a new VTEC spool valve filter [8] and the VTEC
spool valve [9] to the cylinder block with the two bolts (8
x 50 mm) [10] and bolt (8 x 75 mm) [11].
Wipe the oil off the mating surface of the cylinder block
and the crankcase.
Before installing the crankcase cover, apply a 1.5 -3.0
mm bead of liquid gasket (Threebond
equivalent) to the shaded part as shown.
• To prevent leaks, do not install the parts if 5 minutes
or more have elapsed since applying the liquid
gasket. Instead, reapply liquid gasket after removing
the old residue.
• After assembly, wait at least 30 minutes before filling
the engine with oil.
