Today I found my Esco strut on the bottom and oil on the nose tire and a puddle of oil on the hangar floor.  I figure the O ring gave out but I have no info on this strut.  Previously, on my Piper I had the nose strut leak and my A & P rebuilt it and put nitrogen in--this never happened again.  If you have experience with this please respond.
