(c) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 3 camshaft.
NOTICE:
Do not pry out the camshaft.
Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
30. REMOVE NO.4 CAMSHAFT SUB-ASSY
(a) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 4 camshaft.
NOTICE:
Do not pry out the camshaft.
Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
(b) Remove the oil seal from the No. 4 camshaft.
31. INSPECT CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise on the hexagonal lobe.
(b) Check that the VVT-i will not turn.
(c) Cover all the oil ports with vinyl tape except the port on the
advance angle side (nearest to the convex portion)
shown in the illustration.
(d) Using the air gun, apply about 100 kPa (1 kgf/cm
2, 14 psi)
of air pressure to the port on the advance angle side.
NOTICE:
Some oil spraying will occur. Be prepared to catch the
spray with a shop rag.
HINT:
This operation releases the lock pin for the most retard angle
lock.
(e) Under the condition above, turn the VVT-i to the advance
angle side (the direction of the white arrow in the illustra-
tion) by hand.
Standard: Must turn
HINT:
Depending on the air pressure, the VVT-i will turn to the ad-
vance angle side without applying force by hand. Also, if the
pressure can be hardly applied because of the air leakage from
the port, the lock pin might not be released easily.

(f) Check that the VVT-i moves freely within about 30
range. Avoid moving the VVT-i unit to the most retard
angle position as the lock pin will engage again.
Standard: Smooth movable range is about 30
(g) Turn the VVT-i by hand, then lock it at the most retard
angle position.
32. REMOVE CAMSHAFT TIMING GEAR ASSY
NOTICE:
Do not remove or install the camshaft timing gear (VVT-i)

most retard angle position.
The lock nut has LH threads.
Never use any tools other than the socket wrench.
Other tools will deform the cam angle rotor.
(c) Remove the camshaft VVT-i.
NOTICE:
Never remove the 3 bolts on the gear.
If it is difficult to remove VVT-i, tap it lightly using a plastic-faced
hammer, then remove it.
33. REMOVE CAMSHAFT SUB GEAR
(a) Clamp the camshaft in a vise on the hexagonal lobe.
NOTICE:
Be careful not to damage the camshaft.
