Lots of golden brown oil gunk on the top of the cover, which is apparently normal with BMW's as they recommend oil changes at ridiculous intervals (as per e46fanatics)? Yuck.. Will always be changing my oil at 5k or lower intervals.
While I had everything apart I was also able to route my angel eye wires along with the stock wire harnesses  Don't really notice a difference before and after since a lot of the plastic pieces around the engine bay covered the wires previously, but makes myself feel better having everything routed along the stock wires. Also had to take out the radiator fan and intake to find a missing bolt that was caught in between the undertray and engine, which kinda sucked but eh
