im glade we agree on the conv. small may or may not go away, but lets go over this gas thing again. it dont make any dif. what kind of motor youve got, if it (runs like a dream) other than apitting something out of the tail pipes, when you first crank it up cold. if was gas it wouldnt not be running like a dream unless you have run a fuel line into that 4" tail pipe somewhere behind the heads and i dont think youve did that. if you dont have a head and or gasket porblem then its normal condensation coming from not warming the motor up after you start it. if it goes away and dont get hot after you run it for awhile then its nothing wrong with it. its probably a combination of weather, you exhust system, and driving habits. just think about it for a min. you cant have any raw gas coming out of the tail pipes and the motor runs okey
