OK, I have traveled the country side looking for this goofy tool to take the cap off the opti, you know the little torx screw that holds the cap on the opti.
I even tried the sears hardware specialty store and the smallest they had was 4mm, still too big.
Does anyone know where i can get the tool or what size it is?
Thanks!

 

E5 inverted torx. The only place I have found them is on the tool truck.

 

...or just use a screw from your throttle body top plate. Hold it with a vice grips.

 

Your local hardware store should have torx screw with a head the same size as the inverted torx screws on the opti cap. One of those, a wing nut and a hex nut to lock the wing nut on the torx screw and you have a cheap opti cap tool.

 

Thanks Guy's!

The Opti cap screws are E4. The corresponding screw size, to use as a socket would be T20. You need a "deep" E4 socket to get in the hole in the cap, so the TB screws generally work better than buying an E4 socket.

 

Ditto...thats what I had too do when I worked on my opti.

 

My bad, I was thinking it was an E5 for some reason. I was in the garage last night and realized that it is E4.

 

Harbor Freight has a set of those inverted torx sockets for about 4-5 dollars. They work well.

 

Oh, you mean this.

Total cost less than $1.50

 

I ended up using a TB screw and a pair of vise grips, i expected the rotor to be in 100 pices but what actually came loose was the metal part of the rotor, looks like maybe the little plastic tabs that hold the metal tip of the rotor couldnt hold above 6k rpm's? Those little screws that hold the rotor on were also a PITA but i got em out.

 

And I went and spent $15.00 from the snap on dude for mine.

 

I picked a set up at autozone.

 

After taking the 4 E4's out, what else to take apart the opti?
I see the ends of 4 more screws but cant get to them yet, and dont want to break it trying to get to them!

 

Just so everyone knows, most autozones sell a seperate e4 socket as an individual piece for cheap. That's where I found mine...
