Water in catch can?
I finally got around to emptying my catch can today during an oil change. Oddly, when i pulled the tap, only water came out? I had about 1 cup of water that came out of the can and little or no oil. We drained it into a can that already had a spot oil, so couldn't be sure if any at all came out. The can sits in front of the driver's headlight since ther was no room left with the PL kit and the FPR mounted on the firewall. Has anyone found just water in a catch can before? All I can think is that it is condensation that got trapped somehow, but the can is not set up properly to catch oil?
I'm baffled

the fact that you have no oil is a good thing if it's properly plummed. That means you aren't getting any blow by.
Remember that hot air hitting a cold surface causes condensation (cold pop can on a hot day) therefore hot air from inside the crankcase hits a nice cold catch can and the moisture will condense. This happens enough times and it will fill up. If you are in a humid area this will happen faster. You can eliminate this by keeping your catch can re-circulated back to your engine and not open to the environment.
