First when i pulled it out of the car both the orings were missing off the shaft also the conector on the wire harness was all broke. Then i took aprts the opti the cap and rotor was corroded bad alot of build up and green. So i got a ac delco cap and roter kit. Hopefully that will fix the problem. he problem was misfiring and just before it die it was running on only a coulpe of cyclinders then never started again. Also what is the best way to bleed your cooling system without getting coolant on your opti.

 

I think if you had a lot of corrosion you're going to be sorry you didn't replace the whole thing.

Just put some rags around the bleed screw to catch the coolant.

 

To bleed the cooling system w/o getting it on your opti is to get a piece of cardboard or plastic preferrably and place it under tho gooseneck. I use a custom cut funnel with the long tube ($.99 at walmart). Right down to the drain pan. it gets most of it, and for the rest, just put a rag under the funnel.

BTW, FYI, if you're wandering about the little torx screw for the rotor button...T-4. Auto zone sells the tamper-proof set that has one in it.

 

I personally wouldn't waste my time doing a cap and rotor on an opti. If the cap and rotor are corroded, chances are the rest of it is. I would replace the whole thing with an AC Delco replacement unit.

If it were an easy swap, I'd think differently.

 

The rest of the assembly was fairly clean jut the contact points and rotor were bad. I just had to get what was instock car needs to be running by saturday morning or i'm screwed. I'll lose my job. Plus i only have enough money to do this. So i hope this aleast get me through a month so i can buy a a complete new unit. Thanks for the tip on bleeding coolant.
