Greetings, should this have oil inside, saturating the felt inserts ? Not really familiar with hydraulics.
Thanks

I always figured that the felts should be oily to trap particles and block water. Not saturated as in dripping oil, but more like felt that has been oiled and then wrung out.

That's what I've always thought was right for any breather. If anyone knows more information I'm glad to learn.
