I Donated Too sigmafour Posted February 16, 2016 I Donated Too Share Posted February 16, 2016 Bitter cold this past weekend. I have heard about issues with catch can/lines freezing with water in them but I never thought that would affect me! This happened very quickly. I hope it hasn't done in the turbo seals and just popped the oil dipstick as the quick relief the crankcase pressure was looking for! http://www.sigmafour.net/lgt/IMG_6790.jpg http://www.sigmafour.net/lgt/IMG_6785.jpg http://www.sigmafour.net/lgt/IMG_6791.jpg Thanks to advice from JmPbunchofnumbers about how to clean things up with hot water, dawn dish soap and then rinsing with more hot water and baking soda it all cleaned up okay but next time I will heat up my catch can and return lines if I really need to move the car on a really cold day! http://www.sigmafour.net/lgt/IMG_6794.jpg http://www.sigmafour.net/lgt/IMG_6800.jpg Link to comment Share on other sites More sharing options...
apexi Posted February 17, 2016 Share Posted February 17, 2016 Wow, good to know. I didn't know that this happened. Link to comment Share on other sites More sharing options...
Dispatch20 Posted February 18, 2016 Share Posted February 18, 2016 I didn't know it happened either until I was squeezing ice out of my rubber AOS hoses. Major catastrophe. Link to comment Share on other sites More sharing options...
quick4dr Posted February 18, 2016 Share Posted February 18, 2016 Can an IAG style AOS that's heated by coolant still freeze up? I believe this with my grimmspeed AOS led to my blown turbo seals. but now with the Race AOS ive been clear. Link to comment Share on other sites More sharing options...
I Donated Too sigmafour Posted February 18, 2016 Author I Donated Too Share Posted February 18, 2016 Of course. The coolant won't freeze (or shouldn't because it's got antifreeze) but it's not always hot. Once the car is off, it all goes cold. Any water inside the rest of the system will still freeze.

Nightmaresmk Posted February 22, 2016 Share Posted February 22, 2016 AN good AOS is much less likely to do this because they have warm coolant in them after the engine is shut down so the fluid has more time to dissipate. Obviously his can was frozen bad and never intended to used in the winter. Link to comment Share on other sites More sharing options...
I Donated Too sigmafour Posted February 23, 2016 Author I Donated Too Share Posted February 23, 2016 more to the point, I should have drained my can. Warm coolant will still go cold eventually and there's no where for all the water in the can to go if you leave it in there! When I did finally melt my can, there was a good deal of fluid in the can which I drained out. I live, I learn. Link to comment Share on other sites More sharing options...

When I did finally melt my can, there was a good deal of fluid in the can which I drained out. I live, I learn. Even more to the point is that real separators return the oil and water to the crankcase. If this had happened there should be nothing to drain. If you're going to use a catch can however, then it would definitely be prudent to drain it occasionally. They will definitely fill up and freeze if allowed to.
