I have a SQ480 that is a year old with about 20hrs. on it. I just noticed that oil has leaked from the fill plug on the side. I checked it and it did not seem to be loose. The manual doesn't mention anything about the breather plug on top. Is this a vent to keep pressure from building in the gearbox? And if so, could this be the cause of the leak and can it be cleaned? The only mention of it in the manual is in the dealer assembly portion.
