Was hoping it was just my lower oil pan but...
Degreased the top and bottom of the engine this morning (10am). Did not scrub it, just let it soak for 14 minutes. This was at 4pm after a few hours of driving, the equivalent of a few drops.
Options?

Rear main seal? If so, same here. Mine's been leaking for at least two years. Did an oil change almost a year ago and lost less than one pint. More of an annoyance, especially when it occasionally drips on the cat and I get a whiff of burning oil. Dislike additives, but I tried Rislone RMS concentrate that seemed to reduce the leak by about half. Leaking increased when I drained for an oil change. I just can't see pulling the engine to replace a ten dollar seal. YMMV

I have been monitoring this for a long time but just now got around to cleaning it off so I could change the transmission pan. The oily build-up looked like it might have just been a simple pan gasket fix, nope. It doesn't leak enough to leave a stain on the driveway, just gets built up with oily crud.

Don't suppose there might be any merit in taking a torque wrench to those big bolts and giving them a little hug?

Make sure your PCV system is in order & pulling vacuum on both ValveCovers;
~ Hose+Tube+PCVValve "Long L" assembly from right side of IntakeManifold throat to rear of left ValveCover.
~ Hose+Tube "Short L" assembly from IntakeAirAccordionTube to right ValveCover.
If any of these PCV vac hoses are leaking, disconnected, removed or "modified"
or if the PCVValve on rear of left ValveCover is gummed up (replace PCVValve if it's several years old),
the CrankCase pressure goes up & oil tends to get pushed past the seals.
Once PCV system is in good order; in this order next try
~ retorq of all bolts on the pan,
~ drop pan & install new gasket,
~ fresh oil change & add ATP#AT-205.ReSeal; only "snake" oil additive I've had luck with.

Will check PCV bits tomorrow. Thanks.

Wanted to drop the oil pan anyway to check for shrapnel from the timing chain bits. Figure if there are no broken plastic bits in there it should be relatively safe to replace the tensioners.

Not sure if I will put in an additive. The general consensus seems to be they cause more harm in the long run (swelling all seals and potentially causing more leaks elsewhere). True or not? Don't know, but don't think I will take the chance.
