If you install your Opti and it clicks, but doesnt fire or ignite....you will need to uninstall EVERYTHING and put it all back in again, like I and some others on here have already experienced. Take a GOOD note to do it right the first time, check some other threads on here about Optis BEFORE installing yours..unless you've done it before, then just good luck.
But where my .02 comes in, I wanted to tear apart my old Opti to see exactly how they worked and what was wrong with it (instead of pitching up a couple hundred bux and not knowing WHY im replacing it..). I found out you would need to get ahold of a company like Snap-On Tools or something, and spend the extra doh (around $12) for a special star shaped socket. If you attempted to unscrew those with conventional means, you'd most likely strip them, they are very small bolt heads and it would be a pain to put them back in..etc. So it's a good thing you did end up buying the new one. I myself put a new(er) one in (bought one used, had 3k mi on it) and it almost seems like something is wrong with it again, after only 2 months..not even. I think when my Water Pump went out, it got something in the Opti..
I noticed you spent over $300..didnt transamgt say you could get it for under 230 shipped? Maybe he was talking about the vented..I dunno. Im starting to think its worth the upgrade to convert to a vented opti
anyways, good luck with your new opti, let us know how it goes. Im curious as to how different it is from the original GM ones..dont think there;s really much else you can do to redesign it to make the nonvented any better..
Sorry its so long, good luck! Derek
