Once you get the opti out you will need to take it to your local Sears Hardware and buy a reverse torx socket that fits the screws holding it together. Take your opti with you so you can try the socket and make sure you get the right one. Once you have it apart it's a pretty simple swap. When you put it back together, I always run a small bead of silicone with the gasket to keep extra water out.

Are you looking for this info or are you wanting to know how to pull the opti?

Remove the intake air plumbing up to the throttle body, drain and remove all hoses, radiator and fans, remove waterpump, remove drive belt, remove harmonic balancer (doesn't need a puller, three bolts hold it on...) then remove plug wires and vacuum tubes, three bolts hold opti on. pull straight out and voila! Real simple. Then see above post. Enjoy.

It would be a much better idea to change the whole distributor, because just recently I bought a cap and rotor and began taking the old cap off the car with the reverse torx and i ended up breaking the corroded screws that hold the cap to the distributor off so i had to go ahead and buy a new distributor.

True but it won't come off unless you remove the waterpump and the balancer. I've tried every way NOT to do these things but can't.
