Enthusiasts here that have installed an Oil Catch Can in place of your stock CCV system what issue have you had with your car since you have installed it. Here in the East Cost with the temps well below freezing, the OCC freezing up is a real issue and should be closely monitored. During the winter months the can fills up with oily water that will freeze solid on those sub freezing nights/mornings. During the summer I don't have this problem and can go all summer with out even checking the can that will have very little build up. Also I have noticed a smell coming in through the HVAC system when the car is sitting at idle. It smells like spent exhaust gases or blow by gasses that in theory are escaping from the OCC system but the system is sealed and I have good vacuum pressure. I have capped off the oil return line on the dip stick tube, and I am considering reconnecting it to the catch can to see if that will solve my smell issue.
What other issue have anybody else had, if any with there systems?
