I cleaned out the pollen filter area and replaced the filter today. Noticed that their were two holes in the chamber. One had a bung in it (was facing to the back of engine). The other had no bung and was facing towards the wing (heading under the drain on the outer edge of the engine bay). Should that hole have a bung or is is used to draw air in for the heater?
