Oil leaking from air filter, help!
After purchasing my used 2013 883 with 1200 conversion, I noticed after a few weeks of riding, that there was oil residue near the engine block. I brought it into shop for full tune up and I mentioned the oil leak. He said that the seal was broken on the air filter and that he replaced it, and stated that in shouldn’t have anymore leaks. It’s been a few weeks since then, and it’s back. It seems like the leak is getting worse. (First pic is before I washed my bike tonight, the second two pics are after I washed my bike.) For some reason the website auto rotated the pics.

My friend called it the "Sportster Drip"
Its blow back though the air cleaner. Biggest issue is a stain on your jeans.
Always check your oil level and you should be fine.
I get blow back on my `15 Limited and also did on my '08 Road King. Not as bad as my Sportster but it still did it.

Is that the same issue where ppl run a separate tube/pipe from the blow back to drain under the bike?

2 things folks commonly do to combat this...
1) Don't fill oil tank up beyond the half way mark on the dip stick.
2) Install an external breather system. For example, something like...

There have been plenty of threads on the topic.
You might also consider addressing the umbrella valves. They seem to have a rep for not being effective for very long. Krankvent(s) - used in addition to external breathers - might be one good solution. Not that the umbrella valves would be the culprit here. But, if your are doing an external breather, might be an opportune time to deal with the umbrella valve too.

Without having too much mechanical experience, would I be able to instal to breather kit by myself, or should I have a shop do it for me?

Your going to have to learn how to fix it so start with the breather. Not so much blow-by from the rings as it is crankcase pressure from the pistons going up and down. It used to be vented straight under the motor but the EPA got their hands in the mix. Harley had to vent it someplace and used the hollow bolts in the head to direct this excess oil mist into the air cleaner to be burned
Personally I would create a crankcase breather tube from the cam cover to under the bike.
