Check here concerning a CCV hose freezing up! "Woossshhhhhh-about 20 or so PSI came out...." as posted here https://www.ford-trucks.com/forums/556525-warning-for-those-of-you-who-did-the-ccv-mod-and-live-in-cold-climates.html "I found the back half of the hose full of ice. The engine then built enough pressure to force oil through the turbo seals into the exhaust. Because of this find, it looks like I will be putting the CCV back to stock, as much as I don't want to." The last time I checked, water freezes at 32 F, so it seems to me that almost everyone might be subject to this problem.

And here https://www.ford-trucks.com/forums/594816-ccv-mod-2.html?highlight=CCV+mod it can and has happened. The CCV hose should drain well so there's no chance for condensation to collect anywhere along the entire length of hose.
