You are focusing on the symptoms, not the root cause. You can't just say replace your hoses and your troubles will be gone. Drive the vehicle as it was intended, ie get it hot regularly, and your troubles will be gone because the condensate won't build up. Don't do so, and the condensate will continue to form. Replace your hoses if you like, to deal with it, but make sure and go back and do it regularly because you haven't fixed the problem, just the symptom.
Both engines can pressurize the crankcase and blow oil out, or draw oil from the sump into the intake and risk a hydrolock. It doesn't depend on the engine model, it depends on whether in each instance the CCV freezes in the closed position (thus pressurizing the crankcase) or the open position (thus drawing engine oil into the intake due to vacuum.
