I have an Ariens snow blower that has oil dripping out of the rubber breather tube. I believe that that is what the purpose is for - let oil out. But it seems to be a significant amount. Any idea what would cause this? Oddly enough I checked the oil level and it is still at the fulll mark despite losing what looked like a lot of oil dripping out of the tube and down the side of the unit. I can't say if this has ever happened before. I've only used this thing a few times over the past few years. I would see a very small amount of oil on the floor after using it but I never really worried about it.
I guess it's possible that the oil drips down and mixes with the melted snow and gives the "impression" of a lot of oil and maybe it's not that much. But I am still suspicious. Anyone have any knowledge about what is actually going on inside the engine that causes this?
