My engine shipped with a 3/4" brass straight nipple coming off the breather port. Vans solution for this is to cut a 90 elbow out of a Napa heater hose to make the bend there, then connect to a custom aluminum downspout that immediately necks down to a smaller size (5/8?) then runs down the fwd side of the firewall and terminates above an exhaust pipe to burn off oil vapor and minimize the mess on the belly. Where it vents is similar to how Cessna and Beech does it and I think that will work fine, but the heater hose leaves something to be desired. as it isn't rated for oil and people report they go sticky as they degrade over time. Plus, I don't see why you would use a big hose and just neck it down when theres a better solution. I researched this for a while and discovered in the Lycoming illustrated parts catalog that the AN844-10 nipple is an alternate part for the straight fitting that my engine shipped with. This fitting is a 5/8" nipple rather than 3/4" and it is a 45 rather than a straight fitting. Spruce doesn't list the AN844 in this particular size, but a little rooting around on line revealed that I could get it with a price tag of $19.99 all the way up to $80 depending on who I ordered it from! I called Airparts here in Wichita and they had me one the next day for $25 that I was able to just walk in and pick up. Love those guys. In spite of what it might look like, there's enough room to remove the straight fitting and install this 45 fitting with the engine already on the mount. Changed the fitting and clocked the new one to approximately 2 o'clock. The rest of the plan is to come off that fitting with mil-6000-10 hose in an aft sweeping arc. I was going to just fabricate my own aluminum downspout, but the only aluminum tube I can find locally is a pretty thick wall, so today I just ordered vans option and will cut off the upper portion that won't be needed . This will be a much simpler solution that what's in the kit, but the total cost is going to be about $35 more than Vans kitted solution. Gotta admire the ways they have found to sake a buck here and there. I'll circle back to this when that tube shows up from vans
