Anyone else w/ this issue?
Anyone else w/ this issue? I've heard of this being an issue w/ the TAs but my SS has fallen victom to this 3 times now. I have aftermarket rails and injectors and when we get any kind of decent rain fall the third cylinder back (sorry dont know #) on the pas side gets filled w/ water. The last time this happened (yesterday) we had a trash bag covering the motor and somehow it still happened.
I'm now putting a cover over the car PLUS the trash bag, but it seems like there should be something that could be done ot help prevent this. Anyone else who has had this issue please let me know what you've done (if anything) thanks!
GM starters are too f'ing expensive to being going through them every month!

Sounds like you have a leaking o-ring on the lower injector, letting water leak in.... should have a major vacuum leak as well.
Lucky you did not bend a rod or split the cylinder wall.
Your rear hood seal should keep water off the motor.... where is it?

I have seen this on over a dozen cars now; my own car included. What I have NOT seen is acceptable resolution.
On my car I changed o-rings (as well did the other people with this problem)and then I changed rails and o-rings again and still had the problem. These are IAC cars so if there were any significant vacuum leak, it would be easy to spot. The IAC counts follow within just a couple of counts of where they were when the setup was new, so though water can leak in and fill a cylinder oddly there is not enough of a leak to be able to even see at the PCM. I gave up looking for it on my own car and began covering the engine and put a cover on the car. That's not really an acceptable fix and won't save you if you get stuck out in the weather.
The rear hood seal is fine on all of the cars, but if you look at the F-body's plastic cowls that are UNDER the seal, they are in two parts and the split is dead in the middle. It creates a channel for water to pour directly onto the top of the intake. On all cars it's the same too; it's the next to the back cylinder on the passenger side that gets flooded. If you look around this site and LS1.com, you will find owners with STOCK bottom ends (and stock rails and injectors) go out to crank their car after it rains and BANG... window the block. The forged motors don't break like that, they break starters.
