I've been advised by my A&P (that is, my Cessna 150 A&P, who has been
involved in building two Lancairs) that concerns about engine break-in are
real, and Lycoming's web site bears this out. Bob Jude sounds like he has
satisfactorily addressed the concerns.
My A&P suggests installing a run-out engine for the first 50 hours or so. An
engine that was removed because it hit TBO, but was otherwise functioning
properly. Work the bugs out of the airplane and then install the new engine.
After the briefest possible ground run to verify no fuel and oil leaks, tow
the airplane to the run-up area, start it up, take off, and run full-bore for
an hour. He recommends flushing the propeller with clean oil while the
engine swap is being accomplished.
I'm not sure I'll do this, but I must admit, there's some attraction to this
idea, mainly deferring the cost of the $25K engine for another six months...
