Am I going to have to remove the timing chain cover to grind the dowel down??

Perhaps if you are resourceful enough, you won't have to. Maybe a Dremel could do it. You would want to keep any metal from getting into the engine.

Hey I just got my opti ouy . I also have a small amount of play, side to side, movement in the bearing. No in and out movement thou. How the sh** do you get this thing apart? What socket because I know I dont have one for that.

ROD keep updating, cause I'm only like 25 miles from you and I'd like to know if your getting your parts locally, Good luck

It takes a female Torx E4 size socket. I had to grind the neck on my socket to narrow the diameter to get it to fit into the recess of opti cap to reach those weird bolts.

I get my parts from Combination motorsports or Jason Cromar... I wouldn't open the opti unless you know its bad. I just took a vise grips to the bolts . The opti costs $195 like I mentioned earlier from Jason and you will need the waterpump gaskets as well as the two O rings for the opti.

I had no intention of "repairing" the opti but I was just extremely curious what was rattling around inside of it.

I got it apart and all I found was a really worn out rotor and cap everything else looks like new. I could see a trace of arcing though but i'm sure thats wires or plugs.Do we have to go to dealer only to get new cap and rotor?

Rodrigues

If your opti died, I would just buy a new one

1995-1997 distributor cap and rotor

I think what dies in an opti is that black sensor...

My car is still misfireing and the SES light is still on. I changed the plugs and wires and it didn't really help. The shop said its my #3 cylinder. I checked the spark on it and it was a lot weaker then it was on my #1 cylinder. So i'm guessing it is my opti. The car only has 50,000 but i don't know what else it can be. What part actually is the opti? Is it the distributor? Also is the cap and rotor seperate from the opti?

What is Jason's phone #? I"ve got the same problem.
took off the opti and it sounded like a box of bolts when you shake it and scrapes when you turn it.

So you guys think the dowel pin on some of comps
cams are too long. I just installed a xe236/242 about 2 months
ago.

Rodrigues

If you didnt cut your dowel when installing the comp cam, then yes it is probably your problem...

I would check that wire with a meter to be sure there was not something wrong with it-new or not.

Yeah i guess i better do that this sunday. Before i go out and spend a money on a new opti. But can somebody please explain to me what the opti actually consist of and what people replace when they get a new one.
