It's just the definition of "0 time," slang version or the FAA
version, Pete. Per FAA, only the manufacturer can 0-time it's engine.
An overhauler can either do a new limits (gut it out), or a service
limits overhaul (replace as needed). In both cases, it's not legally
0-timed. Reliability of a service limits O/H depends upon who does
it, but usually means it likely won't make it to TBO second time
around.
