Air/Oil Separator

[Utah-Jay]

I am researching what to do for my breather tube and really don’t want my belly skin full of oil.

Anti Splat Aero has some interesting stuff

I must say I don’t know much about this stuff, looking for info though.

I have their separator and it works quite well.

Anyone use this one?

FWIW, I read a lot on the interwebs and spoke to a number of locals about having an AOS. As you would imagine the opinions vary, but I opted for no separator. I'll install one if I have a problem...and it will be a good problem to have since that means I'm flying!

Hot tip - it's hard to avoid oil running all down the belly with a TCM / Lycoming, invest in some good two-pot paint and a few cans of engine degreaser.

These engines weep oil like nobody's business, never mind the breather. It seems to come from everywhere. The cylinder head return lines are a classic, so are the pushrod jacket seats.

For the first few hundred hours, the belly will be white with lead only. Then the oil slowly starts

It does help if you don't have oil from the breather making it worse, so do consider these products if you like. I don't have one installed, and I get next to no oil down the breather. Not overfilling the engine with oil helps, it doesn't need 12 quarts. Ensuring you don't get a pressurized crankcase helps too, take care of the cylinders

Oil that is going out the breather in gasified form has been subjected to more heat moisture and carbon , let it go don’t return it to the crankcase

Ok, update, I went with the Anti-Splat… But did not use the oil separator, I did use the crankcase valve in the breather tube option though
