People make the mistake of replacing their Opti's with aftermarket units which is the other reason they go, the geniune AC Delco units are the only ones that should be in those cars.

I agree, people go out and buy the cheapest replacement and are suprised when they fail quickly. That is one of the first things I learned about after I got mine. I never had to replace mine. There are prevenitive measures you can take to keep water from getting into it. Spent quite a bit of time on LS1tech.com. I vote LT1, I miss mine and will probably end up with another soon. My 6 speed LT1 ran high 12s with bolt-ons, tires, and gears.
