Opti problems in the rain!!!!!!!!!
It's an Lt1 what do you expect even vatos don't drive Lt1's lol. J/k go with the Opti from msd it's supposed to be water proof. Either that or get an Ls1, thats the poorest design chevy ever offered as far as reliability..
no ****, i just finished an opti on a vette and what a horrible design, if i have it my way ill never do it again, ***** retarded, for real. get rid of it. i replaced the entire distributor, it was cheap, i wanna say it was like 700 from gm. and then like 5 hours labor, so 1200 and some change, they still had a boat anchor.

ok, the guy (John) who used to run the business that modified the LT1 intakes to work with a distributor is no longer in business. I found a mirror for his old site though that shows how to do it.
How to modify LT1 intake for use with distributor.
The pictures can't be clicked on and made larger, but they are big enough to see what he's talking about. If you don't want to give this a try then you can always either replace your opti with a different unit or get rid of it all together with a Delteq Direct Opti Replacement Unit. It's just under $800, but it takes the opti out of the equation completely.

Ok before i order that kit can i put a msd cap on stock. If so then that means the msd cap would be water proof rite
No, the MSD can still fail. MSD's have failed, just not as often as factory ones. They may stay drier for longer than a stock opti, but the opti is still a flawed design. After not having an opti to deal with (after messing with them from 2001 - 2008) I'm never going back to an opti design. If I do another LT1, I'll do a distributor conversion or go with Delteq.
*EDIT* - But it's your car man, I don't want to sound like you HAVE to go the Delteq or distributor route. I just want to let you know that there are options out there other than an opti. Depending on how often you drive your car in foul weather, the MSD will probably be just fine. Just know that it's not a 100% cure. You may put one on and then never notice the issue again, or you could put it on and be fine for a year or two and then have a seal fail and experience the same issue when it rains again.

Well **** lol!!!! Ill try the msd man money kinda of tite rite this minute. My wife drives this car more than i do lol. So can i just take old cape of and button and put msd on that distributer. (msd) cap and button is that ok to do
OK, here's the deal. You can get rid of the distributor part of the Opti by either doing the replacement intake or going with the Delteq kit with individual coils. The Delteq is the route I suggest. But in all of this keep in mind that the car still needs the optical sensor so you will never be totally rid of the opti, but if all you are using is the optical sensor then you can replace the rotor inside the opti with a disk made of plastic and the balance issues that cause the rotor to fall apart are no longer an issue. I do recommend the Delteq set-up, it was the best thing reliability wise I ever did to my LT1 car.
The opti is not that bad to change, I can do one in about 3 hours start to finish if I'm taking my time, but that's also because I've done it quite a few times. In your situation I think you should look at the vacuum and vent lines on the opti. There is a vent on the bottom that will take in moisture, but that moisture is supposed to be sucked out by the vacuum line on the opti that goes into the intake. It has a blue thing on it that I don't know if it's a check valve or a filter. If that line is attached and working then the moisture should be getting pulled out. The best advice I can offer is to carry a can of compressed air with you and when the moisture gets in there just put the straw in the vent hole and blow it all out. That will get you back running for almost free.
