How many hours is a Lycoming engine good for?
I could take the easy way out and tell you that, in accordance with Lycoming Service Instruction 1009AW, the recommended Time Between Overhaul Periods is 2,000 hours. However, that’s only a recommendation and there are many factors that need to be considered before you can make a decision about your particular engine.
How often do Lycoming engines fail?
The ATSB’s 2014 investigation into failure rates in piston engine powerplants showed that the traditional Continental and Textron/Lycoming engines had a failure rate of about 13 failures per 100,000 flight hours, with Rotax coming in at a slightly higher 15 per 100,000 flight hours.

How long does it take to break-in a Lycoming engine?
50 hours
Run the engine at high cruise power levels for best piston ring/ cylinder wall mating; Continue break-in operation for 50 hours or until oil consumption stabilizes. These simple procedures should eliminate the possibility of cylinder wall glazing and should prepare the engine for a long and satisfactory service life.
Is Continental or Lycoming better?
Continentals normally have more valve trouble than Lycomings. Lycomings have better valves and guides. A Lycoming usually has its carb mounted to the oil sump, either the bottom or rear, and feeds the cylinders via tubes cast into the sump and connecting tubing from there to the intakes.
