Guys I am cleaning my oil system on mill cause it just don't look like all areas is getting enough oil.So I have remove the manifold and clean it which there was some nastys inside it.So I pulled the orifice's which are #0,#1's.As I am cleaning them I am using a dental pic and probing around on both sides removing what looks like oil hard oil.But on the inlet side of each orifice there seems to be maybe a piece of felt in each one.Is this some kind of filter or is this just pieces of felt that came from the oil pump screen?I know it don't show up well but out of one I remove this small piece which looks like felt or just some trash.So is this part of each orifice,if so what is it there for?I'm wanting to remove it cause I think this is the reason why some areas getting oil and other areas are not.I have check the 5/32 lines and they are free.Thanks for any suggestions
