Good afternoon,
The seals are behind the camshaft gears and the crankshaft harmonic balancer.
The front of the engine has to be torn down. The belts, pulleys, mounts and the front cover. The timing belt will have to be removed and the gears removed to gain access to the seals.
This is a huge project for doing at home.

10. Set No.1 cylinder to approx. 60 / BTDC compression
Turn the crankshaft pulley, and align its groove with timid mark "0" of the No.1 timing belt cover.
NOTICE: Always turn the crankshaft clockwise.
B. Check that the timing marks (TDC mark) of the camshaft timing pulleys are aligned with the timing marks of the No.4 timing belt cover.
If not, turn the crankshaft 1 revolution (360°)

c. Turn the crankshaft pulley 60 counterclockwise to place the sub timing mark (60 mark BTDC) on the crankshaft pulley at the timing mark "0" position of the No.1 timing belt cover.
NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come into contact with each other when you remove the camshaft timing pulleys (steps 11 to 17), thus resulting damage. So, always set the crankshaft pulley at the correct angle.

d. Check that the dot marks (60 mark BTDC) of the camshaft timing pulleys are aligned with the timing marks of the No.4 timing belt cover.
E. Remove the crankshaft pulley bolt.
NOTICE: Do not turn the crankshaft pulley.
11. Remove timing belt from camshaft timing pulleys.

17. Remove VVT-i (Intake Camshaft Timing) pulley.
NOTICE:
- The 5 bolts shown in the illustration determine the backlash of the gear in the timing pulley, so do not remove them.
- If any of the 5 bolts are removed, install a new cam-shaft timing pulley assembly.
- When removing the straight screw plug, follow the prescribed procedure in order to avoid spilling oil on the timing system parts.
A. Rotate the VVT-i pulley from left to right 2 to 3 times within its range of movement (30°) and use a waste cloth to collect the oil from the camshaft timing oil control valve installation hole.
NOTICE: Approximately 20 cc (1.2 cu inch) of oil will be ejected, so take care not to spill it.

b. Holding the hexagon portion of camshaft with a wrench.
C. Using a 14 mm hexagon wrench, remove the straight screw plug and seal washer.
NOTICE: Some oil may spill, so put a waster cloth below the plug white doing the operation.
D. Using a 10 mm hexagon wrench, and remove the set bolt and VVT-i pulley.
E. Remove the wrench.
