LyCon Case O-Ring
I use LyCon oringing on the majority of the engines I build and on all my personal engines. Never had a seep. LyCon now has an STC so they can o-ring certified engines cases as well. Well worth the effort and expense.
Excellent article and photos by the way from Tom Wilson of Kitplanes.
