The "Ney Nozzle"
Special STC developed after 3 years of extensive research on the cam problems of Lycoming engines. The Ney Nozzles should be of particular interest to owners of airplanes with certain Lycoming engines, specifically the 76 series which are known to be camshaft and lifter consumers. The 76 series use barrel lifters, so familiar to mechanics working on Continentals. In addition, these models placed the camshafts further from the crank, which could mean a reduction of slung oil lubrication.
