There's a little difference. When the engine breaks in your car, you
can pull off the road and call a tow truck.

Humm, I don't know a single person that has had a broken crank, in his car.
Can you say the same about your friend's airplanes?

I had a broken crank in a 356C Porsche (rebuilt engine/chromed crank). I
think the real problem was that the shop that chromed the crank didn't
bake it properly to eliminate hydrogen embrittlement.


When an auto engined airplane powerplant fails, it is almost always not the
engine, but what has been bolted to it. It seems like airplane engines are
always blowing jugs off, sticking valves, and breaking rods and cranks.
They are not confidence inspiring, to me.

True, auto engines in airplanes have a way to go, but if someone were to put
the effort into making a standard package, and perfecting it, they would
really go far. Some are getting really close.

I had an E-225 swallow a valve in a Bonanza once -- shook like hell at
anything over 1500 RPM!
