You can re-tighten with the end of a ball type allen, or when you remove your header, replace the bolts with some grade 8 black hex head bolts, use a lock washer, and use red locktite...blue if you are afraid of red. Torque to service manual specs. Then it's fixed for good.

I took an allen wrench and cut it to size so that it reaches into that area properly without having to take off the header to torque it. Most wrenches have too long a neck making it difficult to get in there. Makes it easier to do a quick check whenever the thought hits me.

The most common leak is the two lower transmission side plate (bearing housing) screws. It's not the chrome cover that says "six-speed" on it, it's the plate that the cover bolts down too. There is an exhaust bracket attached at this point and these two screws always seem to loosen up. I even lost one of mine as it backed-out completely. Check those two screws - I'll bet they're loose. Just tighten them and the leak will disappear.

The last time I tightened mine I removed the screws and added lock-washers. Haven't come loose again since.

I have a 2011 Ultra that an oil leak just showed up at 30k and is dripping oil off of the drain plug. After reading your post and further inspection I see that the cover that you are talking about is wet, its appears to be all running down from that area to the drain pan bolt. I will let you know what I find after I tear the exhaust bracket off and install the lock washers and torque the bolts. Hopefully you are correct as it sounds like you are. thank you.
