ES2 CEO, are you guys using any sealant on the head studs? I fired mine up today for the first time, and it is definitely getting damp / seeping anti-freeze as one of the head studs. After it cooled on the first head cycle, I check torque again, and it are spot on. Each one of the studs has an alumium washer on it, without any sealant, wondering if I should removed them one at a time and add some sealant. Thoughts??
