I have noticed after the last couple of trips an oily film in my engine box near the aftercooler. It almost looks like an exhaust leak. It seems to be getting worse after each trip. The culprit is the weep hole on the bottom of the aftercooler. I have a new breather filter, have no blow by from the oil fill, have a raised valve cover with tub that leads to the air filter and have not noticed any power loss. Would like to resolve this as the new gelcoat job in the engine box is getting thrashed. Any help would be greatly appreciate it.

thank, Zack
