Pulled aircraft back into hangar and removed cowling. Found some oil drips on the bottom cowl; source was top of oil filler tube which pushed a couple of drops out after refitting dipstick. Sent photo and text to Jason Smith at Aerotronics regarding #2 EGT malfunction; unwrapped and inspected wiring connections for #2 EGT probe. No obvious disconnections; loosened OLC-1 connectors, wiggled wires and resecured.
