I'm referring to the one at the upper left of the crank snout. It appears to not be used, but it also doesn't look like it bottoms out like the rest (there is something else back there). I'm thinking it's just connected to the main stud threads (no clue why), but I want to make sure it isn't an oil pressure port that needs plugged. Thanks!
