All manufacturers do not recommend a top overhaul. Some manufacturers indicate that a powerplant requiring work to this extent should receive a complete overhaul.
How reliable are Lycoming engines?
While the poor reliability of Jabiru engines jumps out (with over 40% of the engine failures), the study still found 86 failures of Lycoming and Continental engines.
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.
What is the TBO on a Lycoming engine?
TBO, or Time Between Overhauls, is a time limit specified by the engine manufacturer for a specific engine in a specific installation, after which overhaul is either recommended or mandated depending on how the aircraft is used. In a Piper Cherokee 140, for example, the Lycoming O-320 engine has a TBO of 2,000 hours.
Why do engines fail?
Improper Lubrication One of the most common causes of catastrophic engine failure is not ensuring the engine is getting the oil that it needs. Even if you change the oil on a regular basis, if you don’t check other parts for wear and tear, you could end up needing a new or used engine replacement for your car.
