Magnum awesome write up. This answered a lot of unknowns that I was about to begin searching around. Always learning something new. Thanks!

PCV setup info: I'm currently running clean side straight to 1LE oil separator and plugged inlet on the manifold. Dirty side is routed stock but with a catch can w/ check valve and breather/pressure relief attached to the top of the can.

I'm looking at three concerns/questions for the upcoming winter:

1. Clean side oil separator being replaced with an elite catch can with a check valve

2. Any personal recommendations for an engine blanket or block heater? I will be seeing those 25 degree temps in NY

3. Any reason the dirty side catch can/breather/pressure relief combo would cause problem in the colder temps?

I have researched and understand the oil separator issue but my gut feeling tells me I should be worried about the breather on top of the catch can as well. Can't find much on it
