2.7 2tr-fe blowby

I have a 2012 with the 2tr-fe 2.7 with 134k miles. I have changed the PCV valve but still have a slight amount of air coming from the fill cap when open and running. Not enough to even dislodge the cap when sat on the hole unscrewed, but I can feel it on my hand. I read elsewhere that 10-15% on a leakdown test is normal, but i would like some other opinions. Should i be worried, or is this normal? Thanks guys

Edit: After 2k miles since the last oil change, it has run through about 1/2 quart of oil, but has a seeping valve cover.

 

I know this is an older post, but is your motor still running strong and are you sure it was pushing air out and not sucking in
I took mine off the other day just out of curiosity and it was sucking in. It seemed like I’m not sure what they say about gasoline engines. I know on a diesel blow by is not good
