So, yesterday my JEEP decided that my pant leg was too clean and proceeded to start leaking oil. It has never leaked a drop, but this came on swift and severe. I tightened the fitting a little more, though it was not loose, but it is still dripping. So, does this indicate I need a new oil pressure gauge? Or, should I swap the copper tubing for nylon and see if it stops? The oil appears to be coming from the connection, not a crack in the line or from the gauge. Is there a small o-ring or gasket that might have gone bad? Sorry for the stupid questions, but it is not easy to see up there behind the dash to really figure out what might be going on.
