Today I installed the breather tube. I had to cut the flexible elbow to fit properly between the fitting on the engine and the breather tube that gets secured to the firewall.
I'm not sure at this point if I will install an air/oil/water separator or not. I'm leaning towards purchasing one so the belly of the plane doesn't get covered with oil and also to cut down on oil consumption by having a return line back into the engine.
Right now the end of the breather tube will just angle over the exhaust so the oil should burn off but this isn't 100% effective.
