Holy shit his motor was like a treasure chest of goodies huh?
Well I actually ran into some heavy rain while on the highway and after I got home I checked my filter and it was bone dry, but there was a small puddle in the lower part of the ducting, I guess it wasn't forcing the water all the way up.
It'd be hard for the water to go straight up and then make a 90* turn, thanks to gravity and all...
