Engines in cars rarely break. Possibly as rarely as _real_ airplane
engines. However, I have seen a broker crank in a 40 HP Volkswagen, which
my brother and I bought. We rebuilt another engine and installed it with no
further problems. I also used to know a truck mechanic who saw the
occasional broken crank; usually, or perhaps always, after seeing a failed
torsional harmonic dampened--and trying without success to convince the
owner to replace it.

I leave it to the reader to make the connection; as I have beaten that dead
horse far too much, and not only on this NG.

And the failed cranks in these cases resulted in the car being pulled
off to the side of the road.

I've had a thrown rod in a VW, a broken distributor in a Corvair and a
jumped timing chain in a Ford. In all cases the result was getting towed.

Maybe aircraft engines are better built. In my 900+ hours I haven't had
any problems in the air, but I have flown planes that have had failures
in their history. Makes my wonder how long it'll be before my hand is
dealt.
