I was outside looking at my charcoal canister today to help someone out in another post, when I noticed some moisture around the top of the evap canister. All the hoses are hooked up properly, but I doubt the amount of vapor coming through the lines could have been responsable for this much moisture. It completely covers the top of the canister, and extends an inch or two down the sides. It doesn't smell like gas; actually, it doesn't smell like anything. I don't think it's just moisture, the car's been off for a while, and this is the only spot that looks "wet."

How could I go about diagnosing something like this? If I'm not mistaken the canisters are more replacable than they are servicable.

the cannister should only have fuel vapors go into it under normal conditions. Under some malfunctions it will get liquid fuel into it. I do not see how it would get water or anything else into it unless somehow you were getting water in the evap system in some way. I could not tell you how mine operates since it is in a cardboard box in my spare room

The only problem I had with my canister was that the felt filter got torn and leaked charcol EVERYWHERE.. You could try unhooking it and unbolting it to examine it throughly.
