I found that it wasn't cast evenly, so I just used an razor blade and trimmed the other end so it was a bit wider and it went in smooth and secure. I think my issue was trying to push the marker in enough to get the back to catch, which would pop the clip out the other end lol bugger.

So I haven't lost more than maybe an ounce of oil since I did my oil filter housing gasket and valve cover gasket though! I'm super happy, I know the small oil loss was from the lack of sealant on the valve cover and some through the CCV system...

On that note, anyone ever install a catch can with keeping the CCV system? I've got the bare fittings for the 3/4" hose from the valve cover to the CCV valve, I was going to get some 12AN push lock hose and give it a try with a billet can mounted by the air pump lol.

Also surprisingly the valve cover wasn't nearly as gummed up as I was lead to believe, it has some emulsified oil on it, but not too bad. I'm running some different oil through it now to clean everything and then back to Castrol and we'll see how clean it is after.
