Hello maybe me being over anxious but had starter replaced mondAY ....and today had a look under car and noticed what you see in pics looks like oil...anyone else had oil from disptick tube lower end appear like this as a leak?

Guy changing starter in process removed the bolt 18(then replaced all) that actually holds the dipstick housing tube , so wondering if this and wobbling of dipstick tube damaged the o-ring on its lower end...car was leak free so far since purchase!very very frustrating, ding dong also left off some screw that hold the plastic underbody in place...cannot for the life of me find it on realoem so may have to stick in some customem grommet or screw.
