I was cleaning out my filter and airbox and got to thinking about the tube that connects from the air intake lid to the crankcase. I noticed some dirt inside the tube but I didn't see any filter for it.........Uh, this is the crankcase vent right?

 

 

ya, and there has been much debate on whether or not this line should be filtered or not. I filtered mine, measure the line then go to auto zone and get a filter for it

 

Never mind I found this

I wonder how much dirt got down there so far?
