Hi!

Thanks for all replies.

When you say "overhaul", what does this imply?
Is it an engine change, or just a major visit to the shop going through
everything and changing whatever is needed?

note: I'm not an A&P, so I might get some of the terms wrong.

At a minimum, "Overhaul" means disassembly, checking that
each part is within service limits, and reassembly. I think
there are also some parts that must be replaced whenever the engine
is disassembled.

Most people I know want an overhaul to new limits, where each
part is checked to make sure that it has the same dimensions
as a new part. Also, some overhaul shops replace some additional
parts with new because their experience is that doing so will
reduce problems down the road.

When I had my engine overhauled, I didn't do an engine swap.
The engine only had ~2300 hours TT, so I had it overhaul to
new limits (and opted for new cylinders). A friend saved
time by doing ae engine swap.
