and as far as the crank bolt... i've only dealt with it once and what i did was drive down to the acura dealership... go to service and beg, plead, and whine to get a way to borrow their crank pulley holder... it's an amazing tool, and it will allow you to back off the bolt (but don't lose the key in the process)... you would need AT LEAST a 1/2, maybe even a 3/4 drive if your just going to do it with a little brute force
