I was working with my mechanic this weekend on my annual.  I noticed that there was some oil droplets in a couple of places on the bottom of the engine.  It is appearantly from one of the cylinders.  Not much but enough to catch my eye.  I never have more than a drop or two on the nose wheel when the aircraft sets for a few days either.  It hardly requires me to top off the oil as well.  The engine has about 250 hours SMOH.  My mechanic said it is dry compared to most planes. 

All cylinders are 78 PSI and one 75.  It is an E2d with a RAM 160 HP upgrade.

Is this anything I should be concerned about or is it something that is expected and keep an eye on it?

Advice is appreciated.
