Hey Dave, I thought you might jump in on the is one
A few updates - the tanks were never filled, they are have been dry for probably years. No one has even taken a leak in the head yet, so there is nothing in there. The box is dry and the engine has not been run in 3 days now.
It was the following quote that really got me concerned that I had an issue beyond the just a leak
