Visconti Homo Sapiens Feed Leak

[Kodiac136]

I received a Homo Sapiens back in December of 2017. From the very beginning, this pen has been trouble. Upon first inking it up, the pen leaked like a sieve. Somehow, the entire nib had been bent lengthwise so it didn't fit on the feed correctly. I diagnosed the issue quickly, and a new nib was shipped out to me.

I was so excited, thinking the issue was solved. So I inked it up again... and it still didn't work. While it no longer leaks as badly as it did before, the feed comb slowly (by slowly, I mean within a matter of minutes) fills up with ink and then sort of pukes out its contents on the page. The issue seems to suggest an air leak somewhere from what I've read, so I took the nib unit out and made sure that there was plenty of silicone grease on the threads. Still, the problem persisted. Still thinking along the lines of an air leak, I thought perhaps air was getting in where the seal is at on the piston rod. So I put some silicon grease on the seal as well. The feed comb still fills with ink. I've also tried a few different inks, thinking that perhaps the pen just didn't get along with Kon Peki. Alas, the issue still persists.

I spoke with Coles of London and am planning on shipping it back to them, but before I pay the $35 service fee and lose out on my pen for yet another three or four weeks, I thought I would run the problem by the good folks of FPN. Do you have any ideas to solve this issue? I can post pictures later of the feed full of ink if that helps diagnose the problem.
