I'll jump in here. This is from a materials class I had... Ok
here goes,
the piston, when it gets cold shrinks/contracts... the cylinder, on the
other hand, expands (or, to state it better, the walls contract). If you
think about it, for the cylinder to get smaller would require that the
block expand. Thus, bigger clearances between piston/cylinder.
