Lycoming Engine Replacement
Ly-Con Exchange & Engine Overhaul
One of the things that have always concerned me is the lack of any history of my Lycoming 235 C2C. It ran fine with only #3 cylinders running low at 68psi on the last compression test, still within 8psi of the high cylinder. The oil analysis has been clear, even after sitting in the Utah high desert for years. As far as I can tell nothing been done to engine since at least 1988, other than changing the plugs. When I bought it, it had less than 100 hours in the log. I think Lycoming recommends an overhaul within 12 years, not withstanding the TBO. I had always planned to do something within 500 hours, so decided to do it now.

One of two engine test cells, separated by a control room or blockhouse. Engines are fully intrumented during runs.
