Catch cans in winter

[riflex]

Yeah...I know. It's just about to be summer. But I've been wanting to install an occ for awhile now. Ultimately decided to install that and another can to run a dual setup with the Damond PCV plate once i finally gather the remaining parts to go big turbo. This is my daily, and i only have a power goal of 400hp w/ meth until im ready to start building the block. The only thing stopping me from catch cans is what I read about how the contents in the can freeze in cold climates. I live in VA, so in the winter months, I've seen temperatures go down to the single digits. I've also read of people using catch cans in about the same, if not colder, climates with no issues so long as you empty the can frequently so it doesn't become backed up in the event of freezing. However, unfreezing the contents to empty every week sounds like a PITA but if that's what needs to be done, I'll get used to it. Anybody have any other solutions?

Also, my tuner is at about the same power level I want to be at. He isn't running any cans but told me that an EGR delete (which I'm doing regardless) and a valve cover breather cap is enough to relieve crank case pressure. I asked him, well what about the blow by? And he said if I'm getting excess blow by which my engine can't burn off, I have bigger problems such as bad rings or ringlands.

I just made sure I emptied mine often enough that there was never much in it. Not enough in there to block anything when it's frozen and so little that it melts within a minute.

You'd really only have issues if you let it fill up and freeze solid and block your crankcase ventilation entirely.

I empty my catch can after every fill up out of habit so I don't forget and never have to worry about it filling up or freezing. I do get a good bit more in the winter time due to condensation mixing in, but never have I had more than a quarter cup at a time.
