Milk in valve covers

[Lew Silverman]

I found this is a fairly common problem when the engine doesn't reach operating temperature. The valve covers are one of the cooler areas on an engine, so they tend to collect the moisture. When the engine warms up the condensation goes away.

Has anyone experimented with a block heater? I seem to remember that someone used to install a heater in the cooling system to bring the engine up to temperature quicker and cut down on the warm-up which just seems to flush the cylinder walls with fuel. It might also help with the condensation in the valve covers.
