So, I'm not terribly worried about this but am interested in the opinions of
the hive mind here.   I installed a rebuilt 2.1l engine ~3,500 miles ago.
Pretty much since the beginning there has been a slow oil leak from the rear
of the engine.  I assume it's the rear main seal(what else is back there?
 It's not enough to warrant needing to add oil between oil change intervals,
there are maybe 1 or 2 drops of oil on the ground when parked for several
hours.

Oh no woah as me, I know.... this is NOT a major problem, but I sure would
like to have NO oil leaks, is this unreasonable?  Do many people have little
leaks they just ignore?

I reckon I'll just live with it for now.  I have an oil pressure gauge and
oil temp gauge along with an external oil cooler so I should get warned
quickly of any lubrication troubles.

carry on,
