Looking at a 2007 335xi with 98k. Got it on a lift last night and took a couple pictures.

First, I am pretty sure the pan gasket is leaking. See photos below. It looks worse than I think it is because the car got pretty wet driving over in the rain, so there was a lot of water on everything too. Anyway, all the oil seemed to be confined to below and behind the oil pan. We found no evidence of any oil above or in front of this area.

Additionally, I noticed this shock looked like it might be leaking:

And finally, something around the power steering pump. I suspect this is just an o-ring:

Any feedback more than welcome. Thanks!

So.. easiest issue to toughest:
1. Yes, PS reservoir cap is known to leak on most E90, get the cap o-ring replaced.
2. Shock: I really can't tell, use engine de-greaser and observe where the leak comes back from (if it does).
3. Engine oil leak: start at the top inspecting common failure components: Valve Cover gasket, Overhead Filter Housing Gasket, move down from there: oil pan and crankshaft seal gaskets. Might have to clean and observe also. The dealer used UV dye to find out my crankshaft seal was leaking however to me it looked like oil pan also.

Oil pan gaskets on that engine are common for leaking. I hope you're getting some money off the asking price of the car considering it's an x-drive those oil pans aren't easy.

You are correct sir! I was quoted $1500 by a reputable Indy and 2300 by the stealership. That's why all the questions.

I hit the jackpot a minute ago and found a full inspection report from an O2 sensor replacement last month! It notes a "stage 3 oil leak" from the pan gasket. Aside from that, the only recommendations are some fluid changes that were already done by an Indy.

Not sure exactly what stage 3 means, off to Google...

Re the strut, with the wheels off the ground you should be able to look at the strut over the top of the tire and clearly see if it's leaking.
