Hi Jamie,
The only sure repair in my opinion is to replace the large rubber head
coolant gasket. I had a similar leak for years and put off the repair, This
delay probably has some negative effects for the engine but I'm not
knowledgeable enough to delineate what they may be. The long time List
gurus can chime in. I'm in the process of replacing my leaky gasket.
