So I was working under my car and noticed I had oil seepage around my oil pan gasket. As I looked closer it looked like one of the bolts wasnt tightened all the way because there was a bit of a gap. So I grabbed my 1/4" ratchet with about a 3 inch handle and tried to tighten it. Well, it snapped will all of about 2 fingers worth of pressure. I didnt over tighten them when I replaced my gasket, and I used a torque wrench, nor did I use nearly enough strength to snap that bolt. Anyways, does anyone have any suggestions on how to get that broken bolt out? And should I use grade 8 next time or is that too strong? I dont want to crack the block with a bolt thats stronger than the block. I plan on pulling the pan anyways to weld on my return bung. Also is my gasket reusable. I swore I read that somewhere. Its pretty new. I did my rebuild last spring. About a year ago.
