How much damage would I have done if I just discovered that there might have been a small vacuum leak where the PCV hose connects to the intake large side nipple?

I have stillen gen 3's installed and for those nipples I just tossed on some rubber hoses with no clamps to the Stillen nipples, so the hose was just resting on the nipple loosely with enough room for unfiltered and unmetered (this is after the MAF sensor) air to get into.

It's been like this for the past half year at least.

How much damage could I have done to my engine with possible lean conditions due to intake vacuum leak? I don't race but I do run it hard here and there.
