Wear from cold starts and inactivity

[Domenick]

Here in the Pacific Northwest our falls and winters are long, damp, and dreary affairs. Weeks or a month can go by without favorable VFR weather windows. Planes, such as my Warrior, can easily sit for weeks or even months.

When an engine is started after long activity without preheat and without pre-oiling, which parts are affected most, and precisely how might they attribute to reduced engine longevity?

I had good luck with my last engine despite long periods of inactivity. What might account for my good luck?
