What is the failure rate of Lycoming Engines?
The top-line look at engine failures reveals a measurable disparity between Lycoming and Continental. On a failure rate per 1000 engines, our data shows that Continental has an overall rate of 1. Lycoming. Certain problems tend to occur more frequently in one brand or the other. Continentalshave a lot more crankcase cracks, head-to-barrel separations, and premature valve guidewear problems than Lycomings. On the other hand, Lycomings suffer stuck and broken valvesand spalled cams and lifters much more often Continentals.
