I translated and summarized the following for an RV-7A builder in Italy named Lucio.
He acquired a used Lyc IO-360 A1A in parts (no history or other info given),
and a trusted mechanic can rebuild it for 8K euros. He would like to know
if this type of Lycoming is a trustworthy engine for the RV-7A in general, any
historical problems with it, etc. Also he would like to know if it is worth
rebuilding this engine vs. buying new from Van's. With devalued dollar, he can
get a new engine cheap, BUT with high transportation and import taxation costs,
it would add up to 22k euros (north of $30k).
OK, my take on this:
Can't tell much about whether the used engine is any good from his note. Crankshaft
OK? History of damage/prop strike? TT and TT SMOH? Why is it in parts? Corrosion?
Camshaft OK? Any AD's on the parts/crank that need complying with? Basically,
I would advise to have the engine inspected by a knowledgeable mechanic
first, before agreeing to a $12k rebuild. There are many stories of these used
engines ending up costing far more than a new one when everything is done.
Since this engine is in parts, it will be much cheaper to inspect than doing
a teardown.
As to the IO-360 A1A engine and the RV-7A, it is a popular combo (more as in the
carburetor configuration) and would be an excellent powerplant capable of meeting
Van's published performance speeds at fuel burns near 8 gallons per hour
lean of peak with the fuel injection. Any other thoughts from group?
Thanks,
Carl
