Hi Bob,

He's running with headers - no lower shrouds - and I think he's in CT.  What 
he's doing to heat the cabin, I don't know.

The original question was something like "can an engine run too cool".  It 
sounds as if he's not getting the engine warm enough to evaporate the 
moisture out of the oil to me.  Certainly, the ambient temp must play at 
least SOME role in that.

Later, JR
