Trunk Leak in '98 Civic EX (not tails, or sunroof drain, or trunk seal)
Just like it says.
I can't find the leak for the life of me, I've read numerous threads about trunk leaks and no one seems to be able to fix this problem.
I have, however, siliconed the hell out of the weird flappy air vent on the rear drivers side wheel well (just above the wheel well). Also there are two white plastic clips that hold up the bumber on either side of the rear end (also just above the wheel wells) that I saw water come flying through when I dosed the car with a hose. I siliconed, and sealed those off as well.
I thought I solved the problem, but after another rain storm here in north cal. I once more have a fish pond, in my trunk where my spare tires sits...err.. floats.
Any adivce would be helpful!!

I tried that, thats how I found that those white little clips that hold up the panels leaked. I seriously cannot find any other leaks yet there is like 10L of water in there.

put the back seats down, get back there with a flash light and have a friend spray the car witha h ose till you can spot it.
Sounds like the trunk gasket might be bad though.

DON'T blast the trunk with water. Watch this, I'll prove to you that blasting water at your car can make it leak where there isnt' really a leak at all.
Get a friend to sit in your car. Now turn a hose on full blast (the car wash sprayers work well for this too). Stand behind the door and blast the water into the door jamb at the rear edge of the door. Get the right angle and your friend will end up soaked.
Now that we've cleared up that actually spraying the hose at the car won't help diagnose any water leaks, let's explain how to do a leak test on the trunk.
You're going to need two people to do this. One folds the rear seats forward and lays on the folded seats with a flashlight. The other stands outside of the car with a hose or a large cup of water. I'd recommend stripping the trunk interior for this too (a good idea if you have a trunk leak anyway).
Now, the person on the outside with the hose or cup will start FROM THE BOTTOM. Gently spray or pour water onto the car. First pour it on the lowest suspected place for a leak. For example, the taillights.
Wait for a second. If the person inside says it's leaking, you've found your problem.
if the person inside says it's not leaking (give time to let it trickle down) then time to try again. You now know that it's above the point that you previously poured water on now.
This time test just a little higher. Maybe right above the taillights, at the corner of the trunk.
Go on like this until you've narrowed it down.
This is how we found a leak in my '98 EX coupe. My leak is on either side of the car, coming in through the rear winshield seal about six inches from the top of the glass. On the inside of the car it drips in around the trunk arms. So it will often drip inside to a place not near the source of the leak.
Sources for leaks in 6G coupes:
- Moonroof (seals around the moonroof, plus there are drain tubes, one on the front driver's side and the other on the rear driver's side).
- Rear window seal (this requires the rear window to be removed and reset).
- Taillights (more common on hatches, but the cheapest thing to replace).
- Trunk seal (carefully go around this pulling it apart to look for cuts in the seal).
The vent in the side of the bumper and the white clips are *highly* unlikely to be the source of the leak. Honda designed those to be just like they are and in order for it to let water in, you do have to hit it with just the right angle and pressure. The vent is strong enough that if you pour water over it (even with the bumper off), the water doesn't get into the car.

I added on. I mentioned the solution for my leak (rear window glass has to be removed and reset. I'll need a new inner seal and possibly new glass if it happens to break.).
For the taillight gaskets you'll need new gaskets. For the trunk seal you'll need a new one. For the moonroof seal you'll need a new one and the drain tubes often just need to be plugged back in again.

You might want to check your air vent. There's a vent behind the panels that has a rubber flap that vents the air in our car out behind your bumper. Some times the rubber flap gets worn or damaged and can cause a leak like you're talking about.
Hope that helps.
