[Healeys] Engine temps too low.

[Oudesluys]

  Theoretical:
A cool engine generally runs less efficient as fuel droplets from the 
carbs evaporate to a lesser extent in the manifold/head leading to 
incomplete combustion, carbon build up on the head and pistons and a 
higher CO content of the exhaust gasses.
Water and fuel evaporate less quickly from the engine oil. Maybe less 
efficient removal/absorbtion of dirt and contaminants by the engine oil 
leading to sludge forming.
