I would add to great advice by Raz: Check condition of timing belt and replace if necessary, you will have to remove the motor mount on that side to get it out.

Also check the oil pump seal, if leaking now would be best time to replace it.

Also check lower timing belt cog (on crank), it slides over a woodruff key and if any play it will affect timing. You can buy new ones from Toyota for about $60.
