Its kinda dented, and oil has been leaking out of this little spot for a while now. It's just little dribbles here and there but its still leaving a spot on my driveway. I also don't want to change the pan, because that requires me taking the whole engine out and thats just not happening. Can i just clean around the area and put some black rtv gasket maker silicone stuff on the spot or is that a bad idea?
