PO of our boat was a mighty over tightener of all things. One of the coolant petcocks had a slow leak because the o-ring was damaged.

Found a slightly larger inside diameter, but thinner o-ring in an old partially used Racor rebuild kit. Gave a couple wraps of Rescue Tape around the petcock so the o-ring would fit snug, then some more wraps over the o-ring to bring it up to the needed outside diameter. No more annoying leak
