Lol no, the air doesn't actually come from the crankcase, it comes from that breather because the crankcase now has an opening to atmosphere. Air gets drawn through the crankcase. Its not a huge problem, but the computer noticed something different. The solution is to simply adjust VE for the breather, possibly some idle settings. I have seen this issue on both MAF and MAF-less vehicles.

The only thing I can think of is the PCM is calibrated to account for air being pushed in through the PCV system, which it is no longer getting because it's capped off. But wouldn't the PCM adjust itself for that? Or is it a big enough change that it would need to be tuned for.

Sucks to hear man. I'm glad our deal went smoothly which is why I was as up front about everything possible on the wrx, and I can't say enough how up front you were with the truck. Even with it down, I'm still in love with the damn thing, and I've sold vehicles in the past over less lol.

Still a issue if the TB port is blocked off? Just curious I have had the pass cover vented, the TB blocked of for some time now. Maybe it is diff under boost, as it will blow out there.

If its set up that way, there is a pressure difference between your crankcase and cylinder under light load while the manifold is in vacuum, so its prone to drawing oil up past the rings. In boost you're fine because the crankcase pressure can escape.
Maybe we need to get a good PCV thread/sticky going?
