You can also vent it yourself, but I would try and get them to replace it with the 95+ part. http://www.corvettefever.com/howto/16758/

The article I posted covers it, but you can't just replace the Opti with a newer one. You have to change the timing cover too. It's not much more work because so much shit has to be removed to replace the Opti anyway.
