A frend of mine recently bought a 2002 Mini in real great condition. He decided to change oil and put the car up on a set of ramps. He cannot get the oil pan plug out. He actually broke a Snap On socket trying. He tried a box wrench and could not break the plug loose. Fearing he would break somethink or ruin the oil pan he stopped. This guy is not a wimp and knows cars. He has a 52 Chevy pickup he has restored and also is in the process of restoring a MG-D. Any ideas for getting it loose?
