haha I don't know why I didn't think of that: just waiting till morning to check for which plug it'd be. Duh. After hearing from you guys, I'm going to return the block sealer. I was hesitant to begin with, but with the info I've gotten, it seems as though I would only be postponing the inevitable, and possibly damaging things further by using it. I'm going to do it the right way and troubleshoot thoroughly first, then just man up and fix the problem the right way. <img src="/forums/images/graemlins/scared.gif" alt="" /> <img src="/forums/images/graemlins/baby.gif" alt="" />
