A silicone sealant adhesion malfunction
in the drive belt auto tensioner
installation bolt hole.
—
A bolt mis-installation due to silicone
sealant hardening.

2. When reusing the oil pan installation bolts, clean any old sealant from the bolts.
Caution
• Apply the silicon sealant in a single, unbroken line around the whole perimeter.
• To prevent silicone sealant from hardening, adhere the oil pan to the cylinder block within 10 min.
after silicone sealant is applied. Tighten the installation bolts completely soon after adhering.
• Using bolts with the old seal adhering
could cause cracks in the cylinder block.

Electric Variable Valve Timing Motor/Driver Assembly Note
1. Install a new O-ring to the O-ring installation groove of the engine front cover.
Caution
• To prevent damage to the electric
variable valve timing motor/driver, do not
apply excessive force (force of 100 N
{10.2 kgf, 22.5 lbf} or more) to the shaded
areas shown in the figure.
2. Install the electric variable valve timing motor/
driver using the following procedures.
Note
• The eccentric shaft on the electric variable
valve timing actuator side can be rotated to
the left and right.
• The electric variable valve timing motor/
driver can be assembled with the joint
groove of the eccentric shaft in any position,
and it will not lead to vehicle damage or
performance reduction.
(1) Before installation, rotate the joint on the end
of the electric variable valve timing motor so
that it is aligned to the joint groove on the
electric variable valve timing actuator side.
(2) Engage the joint on the end of the electric
variable valve timing motor with the joint
groove on the electric variable valve timing
actuator side.
(3) Attach the seal surface.
(4) Tighten the electric variable valve timing
motor/driver installation bolts.
