*HEADS-UP* Oil Catch Cans Mounted in FRONT of RADIATOR
!ALERT! For those in the great white North (or where the temp's have been at or below freezing) -AND- have the oil catch can (in my case UPR's) in front of the radiator a warning ...
In the winter there is a goodly amount of water vapor (more prevalent if there's mostly short trips) mixed with the PCV fumes and therefore it can/does freeze.
Locally the temp's have been mucho below zero and not getting much above 10°F during the day for the past several weeks.
As the result, found that the oil catch can was a solid, frozen block of ice crud internally that did not allow the PCV to evacuate.
Am currently thawing-out the assembly and re-thinking the mounting position for winter. i.e. back behind the radiator, attached to the shroud.Locally the temp's have been mucho below zero and not getting much above 10°F during the day for the past several weeks.

Tothemax ... Did it expand and split anywhere?
When I opened the drain nothing came-out and I noticed that the output hose (to the intake) was slightly collapsed. Took the assembly apart and also found ice crud plugging the diffuser in the upper section.
Should note that this area has set all kinds of low temp' records for the month of February so what's being experienced oil catch can-wise is probably an extreme - no days above freezing, daytime highs not exceeding 10°F (and often below 0°F), and nighttime temperatures as low as -25°F. While the vehicle is ALWAYS garaged at night, it's not a heated structure.
winter..

Is that on an EB or a 5.slow?
If it's an EB that thing is far too small for a cold climate you'd have to be draining it daily. My Mega Can was frozen up to the seperator inside but was still flowing fine, but realized I have to drain it more often. That was with 1000 Km on the clock. It had close to 500 mL inside it.

Yup, up here we insulate it in the winter. Seems to work great. As long as you don't allow it to get too full while idling and driving the insulation will capture the engine heat enough to thaw the can out.

Just still be aware that even behind the radiator on the shroud it still can freeze or collect ice. This is what ice was left in mine after running the truck a for while at full operating temps in -10.

Also why do you think the PCV would not evacuate OP? Unless you ran the level too high there should be no blockage of flow.
