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.
