2000 Chevy Blazer Changing oil lines

I have a slight leak in my oil lines that come from the engine to the oil filter. I tried to replace them but cannot get to the bolt on the engine near the oil pan. It was suggested that I loosen the motor mounts and raise the engine a few inches. I cannot find how to loosen them. If you have an easier way to replace the lines please be my guest to inform me how.
