      I would say opti to. If you are not in a rush a guy on E-Bay has them new for like $185.00. Hope this helps.

        ^ I'm with them; my opti started out like that when it went bad and got progressively worse. Mine was just the cap and rotor but I replaced the whole works while I had everything off including all the front seals.
