Some water, leakage, wet around air intake area
I have noticed few times something wet around air intake area, on the hose where maf sensor is and before throttle body. Every time before it was very small wet area, but recently my brother told me he saw oil in pavement right below the place where i see leakage, and yesterday my car was in garage so there is no way water got inside (it's rainy here) and when i tried to see what it is, it looks like it's water, but it's just a little bit like oily, it sure doesn't look so greasy and dark as an oil from engine or brakes, it's like transparent, it doesn't leave any darks on paper, it's a bit yellow like dirty water and it sure doesn't smell like anything. What it could be? I also noticed my battery looks wet below fuse area, but nothing much, more like moist.
