Oil leak , turbo oil lines

Hi All

Recently took my car to the dealer for a holiday inspection and they picked up an oil leak. I was told that it was leaking from the turbo oil feed lines and rear main seal. From what I have been told the leak is still minor but I will have to get repaired relatively soon. Is this this a common issue? The parts are not expensive but it’s $1000 + on labor costs to repair.

How serious can these leaks become ? Shouldn’t I repair them or just monitor oil levels and top up if necessary.

Thank you

Oil feed line is not common. Rear main seal is common. Honestly $1000 in labor doesn't sound bad as they have to drop the trans for the RMS and getting to the oil feed line is a PITA.

Had the o rings on the feed line replaced at 54k. Not sure how badly it was needed since my SA tacked it on when I took it in for CPO work.

I found the easiest way to remove the oil feed line is to swap (upgrade) the turbo
