Is this residue from RMS? Cleaned it all up (dont have a pic) late last night and will check today if there's any leaking around IMS flange. However, when cleaning, noticed that the lower right bolt on flange was very lose (could turn it with my hand). As I unscrewed it, some oil poured out. I'm thinking I need to order LN retrofit but don't have CAM locking tool needed before I remove flange today to try to determine what bearing I have here. All thoughts or suggestions appreciated.
