Major Issues to FIX

I noticed an oil leak, looks like it's from the rear main seal. It's cool, 01,X5,3.0,254K miles. Is there any product I can use to slow or seal from the inside? Oil gasket sealers you recommend? To big a job n expense to tear into. Is the fuel filter regulator on this March 2000 production the press on fuel line or old style ?
Noticed some small drops of oil/fluid on a few bolt heads on the transmission pan, what or where are these from? Ideas?
Working on repairing ABS sensors with wheel spin test, I have no reader.
Replacing plugs, they looked normal, cona ring and light toasted grey prongs. NO oil in plug holes.
Thanks for ideas on the oil leak.

I have some sort of a leak back there on my 2001 3.0i with 192k miles. Not enough to worry about any time soon, but it has made me pay attention to other reports on here.

First thing I'd recommend is that there are reports on here of an AT leak and an OFHG leak both appearing to be RMS leaks. Seems almost impossible, but upon careful further analysis, photos, teardown, etc. they are confirmed to not be the RMS. So I'd at least hold off on any disassembly, and even additives, since they can sometimes have unintended consequences.

But in general I think it's always safe to choose slightly higher weight oil, of the "high mileage" variety (greater than 75k miles is what it says on the label, LOL, that's a new car to me).

I use slightly higher weight oil and AT205 to condition seals. Has mitigated my valve stem seal smoking greatly.

Seconded checking the OFHG leak vs. a RMS. I have this problem on an N52 currently. Thought I had a bad RMS (186k miles) but turned out to be a bad OFHG. I also feel 75k is a "new" car oldskewel.
