Default Optispark Bolts

I cannot find the socket that will take out the optispark top bolts that hold the cover and base together. I have a torx socket set but it will not fit down deep enough to reach the bolt and I cannot find a deepwell socket to dave my life. Where did you guys find one or what did you use to take it apart? Thanks fellas

I bought the complete opti since I have read several times that a rebuild is not necessarily gonna hold up. New complete opti is 242.52 for '96 from Jeff.

I have torx sockets but none will reach deep enough to get to the top two bolts.

I have had mine apart a couple of times. I think that you may be referring to the male torx screws (vs. female). Try this ~ remove one of the TB cover plate bolts and chuck it into a reversing drill. You should be able to use the female head of the TB bolt to remove the male torx on the OptiSpark.

Once you get the OptiSpark apart, you will need a #8 torx for removal of the rotor. I bought mine from Sears Hardware for a $2.99.

This may sound simple, but here is what I did. I bought some torqs head screws from the "Help Section" of AutoZone. I found a 2" bolt with a torqs head that matched the Opti-Spark male heads and they fit right down the two holes you're trying to get in. I double nutted the end of the bolt and used a nut runner to loosen the opti-spark bolts. Works great and doesn't cost a fortune. If you have 50k or more and drove in some rain, wait til you look inside (especially if you are not vented) :bb

I followed Purps advice from above by using a screw from my old throttle body in a drill. They came right out when I opened it up the white gasket seal thingy was all broken and all the contacts on the inside were green. It doesnt look healthy may start looking for a rebuild kit just in case. Thanks for the advice also. :cheers: Zach

Bummer. That's why I open mine whenever I flush my coolant. I drop the water pump and check the front seal, then I remove the Opti, check the timing cover seal, open the Opti, reseal the gasket, and re-install. After you have done it once or twice you can drop both, flush the coolant, and have it back to gether again in about 2 hours. That's not an unbearable PM when only done every 12 to 18 months.

The upside is that I am not afraid to wash my engine because I know that my Opti is properly sealed. I do use precaution though, and stuff washcloths around the Opti and coil when I power wash. Notice I said washcloths and not plastic. Plastic will deflect water. I want the washcloths to absorb and hold the water.
