Yesterday, when Linda and I got home (no engine cut-outs on the way home, BTW, Charlie), I noticed oil dripping from my oil pan. So I tightened that big 4" drain plug. Still dripping. So I went ahead and changed the oil, put a thicker o-ring on the plug (an old fuel tank o-ring), and tightened it down. Still dripping. And it's definitely coming out in the region of the drain plug. My only guess is that I have a leak there. I'm going to take a closer look this weekend, and try to fix it. If I can't, I may be looking for another oil pan.
If it ain't one thing, it's another.
