Well the stock manifold is out and there is a hose that runs down the left side of the engine going from one breather to another..the breathers are on top the each valve cover..my question is, are those actual breathers replacable or are they part of the cover ?? The reason I ask is that the rear one is seeping alittle oil and it bothers me...its not alot...I did take the hose off and tried to twist it but i didnt want to break it off ?

anyone know
