Oil seep, 912 ULS

Found a little oil seepage during the condition inspection. Looks like it?s seeping from the lower portion of the hatbox case to crankcase seam. How big of an issue is this likely to be? We?re assessing our next steps.

I get an occasional drip from that area. When it hits the muffler I smell it in flight. I checked the case plug for torque and have concluded it?s seeping past the plug threads. Found it two years ago and it hasn?t caused any problems.
