My 34-year-old mid-engine Ferrari - with rear deck vents - has been driven thousands of miles in the rain.. I picked it up in Greensboro, NC, to drive it home to the Dallas area, and within 15 minutes of leaving it was raining elephants and hippos - forget the cats and dogs.... never a twitch, never a bobble. End of the day they're all just cars....

Realize that driving any Vette before a C8 in the rain had a wide open front that literally let any water that got by radiators direct access to the engine? Just because you didn't see water spots on your front engine car, it doesn't mean there isn't moisture getting through. I submit that there is less moisture that actually gets to the C8 engine than in any previous generation of Vette. These vents are not directly over the engine and GM has designed them very well. There is far too much concern over these vents being "open to the engine". The C8 has been tested under more stringent standards than any Vette before it. This car is solid. If you are one of those that liked keeping your front engine car engine wiped down, it will be a breeze keeping the C8 engine compartment wiped down.

I live in Western Washington State. The car is NOT garaged, EVER. It rains here. Had the car over a year and 11k+ trouble free miles.
If letting water get into those vents created a problem, they wouldn't be there. .....
I also use a hose to water wash the car. Water gets in there and up under the glass (coupe) .. Again, No Worries.

I wash my C8 the way I washed my C6, and two C7s. I use a hose with a soaper attachment and rinse with the hose. I don't spray directly in the vents BUT also don't avoid getting all soap off the hatch and rinse at an angle. Yep a few oz of water gets in and IMO more from the seams as it collects in the back. BUT you need some water as forget water, lots of dust gets into the engine compartment!
So I use the corner of a towel and pick up the water. Then use that wet corner to wipe the engine cover and flat surfaces. Then use the bulk of the towel that is dry to dry off the damp surfaces. Takes a few minutes and you do need to remove the dust and dirt. I drive in the rain and don't bother to do anything until time to wash. It's been two years and I agree it's a Non-Issue!

Nothing you can do about driving in the rain. The vents are needed to let heat escape. As others have said, rain won't hurt the engine. If you want to keep water out while washing or parked, here's one option:

Does anyone really think GM would design the cars this way if some water coming in from the vents was going to be an issue? I know GM doesn't seem perfect in some of their decisions/designs, but I am pretty sure in most cases they have weighed the consequences of most, if not all design decisions.

Amoreloba,
Would you happen to have these files as a .dxf or .sldr or any other native file? I can open these files, but cannot dimension them. Also, you mentioned that you would plastidip them for a better fit. I would probably make these from rubber and waterjet them out. Should I make them a little bigger than what is drawn? Any idea what would be a good number for a close fit?
Thanks
Alex

Think we have it figured out. I'll let you know how they turn out.
Thanks for sharing the files. I've been taping over the vents, but if these work it would make it a little quicker and easier.
Just a side question, but how did you come up with the dimensions? Did you use a Faro Arm or something similar?
