Use drift 9995718 for camshaft with  variable valve timing unit and drift 9995719 for camshaft without  variable valve timing unit.

Lubricate the surface of the seal that the camshaft rotates against.

Use the variable valve timing unit/timing belt pulley mounting screws. Tighten the screws until the drift bottoms out.

Remove the drift.

Install the screw holding the inner timing cover to the cylinder head.
