I tried to replace the 91 honda civic engine oil pan gasket to fix the oil leakage. In order to remove the oil pan, I have to remove part of the exhaust pipe, but I have difficulty to loose the nuts. I think the pipe is always too hot so that the nuts are stucked. Also those nuts and screws to hold the oil pan are far to be reached. What kind of tools should be used? I have some simple tools like wrench set, plier, and screw driver. Try to save some money by diy but even can't loose a nut at the first step.
