engine heaters in Utah

I've always had an engine heater on my diesels. Its needed here in Utah for the winters.

The first four had a coolant heater in the lower radiator hose but the 300's had (have) a block heater. My current 300TD develops a very small coolant leak if the block heater is left running longer than about 3 hours but you only need about 90 minutes to really warm it up.

Anyone have any idea why I would get a leak from running the block heater but not from general use?
