Ok people, I have done many difficult technical/electrical jobs so far on my car, but this is the most rediculous thing I have ever encountered. Last night, I decided to change my oil for the first time. For over 4 hours, I tried to get the damn oil-drain bolt off the oil pan! I tried everything....the correct sized metric socket wrench, then the standard wrench, then vice-grips, then a chisel and hammer, and then I tried drilling a hole through the bolt head to put a metal rod through it to twist it off, but nothing worked. I tried all these things many many times before giving up. I now have a worn-down nub where the bolt head used to be. Any ideas on what to do here? -- Mikey
