Yes, I have heard of that too and used to do it with some of my other
cars. I believe that Fred D. talked about that and also Fred believed
in pre-wetting oil filters with oil so that initial startup oil
pressure would not damage the filter when dry.

The theory is to crack the
carbon, but not enough for it to fall on any open valves. Then
starting the
engine breaks it out from around the spark plug and blows it out
the exhaust.
I would think you could look down the spark plug hole and see if
the valves
were open and then blow that cylinder out with an air hose. But a
chunk of
carbon could still come to rest on an open valve. Then when you
turn the
engine, it smashes and makes a gap that can later allow flame to
pass that
area and burn the valve <snip>

I've never read such a
thing, and I'm not sure I follow the logic. What difference would
it make if
you knock off some carbon and blow it out the exhaust ports with
your old set
of plugs vs a new set of plugs?
