Approved Oil Separaters

[Rickskymaster]

Does anyone know of any approved Oil Separaters.

I burn very little oil between changes, one quart every 25 hours, but I am getting tired of cleaning the rear engine area after every flight.

Thanks

Look at M-20 and their web site. Their STC includes most 337's along with many others. The install is easy. All the reports I have seen sauggest they are pretty good and work well.

I have the m-20 on both engines on my 337H for 3 years now. I use very little oil and get none on tail feathers. Just make sure they mount them high on both engines so oil drains back to pan.
The hose of m-20 must have good down angle so gravity does its thing and oil won't lay in hose. Dale Campbell
