Mine is one of the XC90s that went for scrap...

I don't believe the theory I'm afraid, I ran the following test.

Crank case breather hose cut in half, the inlet manifold end blanked off, the other end run to a bottle but left open to atmosphere.

I still found that after engine braking I was bellowing big clouds of blue, oily smoke. It couldn't possible be being sucked out of the engine as that pipe was in a bottle, open to atmosphere.

I'm still convinced it was stuck/blocked/worn piston rings.
