I'd say check the pan gasket. My mone carlo won't leak while you drive but everytime it sits overnight or longer it has a spot under it, someone said it was the pan, i tightened up the bolts and it did stop for a week or two. I know it's not my front seal because it's brand new and not wet up in there only around the pan and lip of the pan. I think mine started agin because I may have split the gasket by overtightening then bolts.
