When looking behind the air intake box on both my engines, the starboard throttle body assembly has oil dripping out around each of the three butterflies but the right ones are all bone dry. Is this an oiling issue or not? Weird that both seem to have the same issue. Only noticed it because the port engine was dripping a small amount of oil onto my boat when left trimmed up for a while. Could be an over oiling issue on starboard side or under oiling on port side. Any ideas? To worry or not?
