E90 VCG, leak, while I’m in there ?

[Inkcmob]

Picked up an 08 335i for a decent price and as expected have some oil leaks to take care of. Dropped it at the Indy for a diagnosis just to save some time and have it all checked out for good measure because why not. Oil dye dropped in, definitely seeping from VCG, also from turbo return line, and cam position sensors, as well as the adjuster(s). On top of trusting the Indy due to reliable service in the past with other cars, uv light confirms sensors are in fact leaking which brings us to the actual question... car is not throwing any codes for cam position sensors or adjusters, so should I swap em out while doing the VCG or just swap o rings to address the leaking sensors? Car is sitting at 105k currently.

Long time lurker, finally here to be an actual part of the board, thanks in advance!
