Oil cap moisture
Is it normal to have some moisture buildup under the oil fill cap after you've driven your vehicle. I always remove my cap after getting my truck back in the garage after a night out at a cruise or car show. Their's always a small amount of moisture under the cap, or even down the filler neck. It bothers me because this moisture hasn't anywhere to go, but back down into the motor and maybe even into the crankcase.
I understand the principals of condensation, but I was thinking more in the way of a vent tube problem or something.
