Need oil leak help
#11
There was about 3 our 4 of us not to long ago that had the same problem. All were leaking from that bottom drain line coming off of the oil tank.I was changing the oil anyway so when I had the tank empty I changed out the hose.I'm using a K&N filter and have no issues with that. If you're going to drain the oil to check it out, I'd check that hose before you pull the filter off and have to replace that for no reason.
I now recall that about 2 weeks prior to changing the oil I was on a group ride and bottomed out on a pothole. The frame hit hard enough that it broke my tail light off its mount. (Krazy glue fixed that problem.) That could have resulted in a sufficient enough tug on the drain line to cause it to start leaking,.
Anyway, going to drain the oil, save the filter, and replace the drain hose.

To close this thread out, I replaced the drain hose last night and no more leak! The part was only $14, but it took me 2 hours to get the hose routed correctly. Getting that hose down the hole in the frame was a challenge until I figured out how I need to route it before connecting it to the tank. (I'm an accountant, not a mechanic.) No more oil drip.
The next challenge is drilling out two derby cover bolts so I can change the primary oil and adjust the clutch. The fun never ends with a Sportster!
Thanks to those who offered advise and commentary. Ride safe!

Reason
found out reason was having problem with after market oil filters ones purchased where specs for 10 micron element with anti flow back flap inside. Apparently sportsters and Evos can't push oil past these there sportster and Evos rated 30 micron and no back flow and thus back flow to oil bag or out breather So just check make sure they meet Oem specs for application. And glad you found line and got it fixed. Ride Safe. Wild Bill
