2017 C300 4MATIC Oil Leak
Hi all: I do my own work on all my cars/trucks and im a little disappointed on this so I figure I would ask before ripping apart the whole engine. I did a UV Die test to find an oil leak I've noticed getting worse and worse since my last oil change. I sprayed degreaser, added the die to the oil, backed her into the garage and jacked her up. Immediately with a UV light I see that the oil isnt coming from the pan/nut, oil filer, etc but rather it looks like it is coming somewhere from the back of the engine, dripping onto the transmission then spraying all over the underside when I drive.
Engine bay is really tight, I took the left side cover off and have pulled my windshield wipers off to remove the right side panel but I couldn't get a snake camera in + the UV light to see where the leak is- god do I miss how open the engine was on my old 97 e420 v8 big block was!
Anyone have suggestions before I start ripping more stuff out? Really disappointed at 42k miles and only a 2017 that this is already happening... Meanwhile my 2011 Ford has never leaked

Put the vehicle in the air or on jack stands and crawl under it.
