But I was just thinking, if I have a turbo at 18PSI, the air sucking out of the crankcase and valve cover is quite a lot. Enough to make a difference do you think?

It really doesn't matter, as the blowby gasses are a mix of inert gases since they've already undergone combustion and some already metered air with oxygen.
It can make small changes to your AFR, but that is just one of those thing your tune has to account for in the K-factor used. That's why I suggest everybody I do a tune for recirculate their blow by behind the MAF on the turbo inlet.
