Did anyone install the louvred plate under the breather tube plate? I did not see it in the aerovee manual. I did see it in the “How to Rebuild Your Volkswagen Air Cooled Engine “ page 140. I found it in some leftover parts. Just put it in today. I’ve had quite a bit of oil on the belly. Hopefully this will decrease the amount of oil spray.

Area51 told me he used the stock baffle and only gets a light mist out the breather. That was on my list of things to try until I got my air-oil separator figured out. My home made baffle was a bust as I reported before.

A couple of points. First make sure it's oriented correctly. It ought to be fairly obvious the louvers go down; the clocking is what's not intuitive. First blush would indicate the radius on the louvers should match the round side of the hole. It doesn't. That plate is the first line of defense against the cam gear throwing oil out the hole. Get it right, or it won't do you any good.
The second point is probably why Sonex doesn't want you to install it in the first place. The hole in the breather plate aligns with a small percentage of the louvers. On a very cold day with a butt-load of moisture trying to reach freedom, it's probably possible to freeze the hole shut.
I solved that issue by installing a spacer between the louvers and the vent plate. Something on the order of .090-.125 thick. It worked very well for me. I had to oil the tail wheel pivot with a can.

That is pretty extreme!!! Using an oil can on your tail wheel.

He's just bragging about how dry his tailwheel is. Mine is well-lubed from oil leaks.

Yes, I understand that. My tailwheel needs no lube.
