Max, I think you missed what killer was talking about. The blow-by gasses are hot and probably the same temp +/- no matter if its the summer or winter. Its the coolant that changes temp. If I understood killer correctly, which blows my mine but makes perfect sense, is that they don't see a reason to use coolant to worm up the AOS canister for short trips because the gasses in the canaster are hotter then the coolant. Hans the coolant "cooling" the AOS not worming it up.
Please correct me if im wrong. I used the Crawford with coolant through it and now I will be using the IAG AOS just because it came with the car that I bought for a project. Never had a issue with Crawford

As already pointed out, incomplete (or incorrect) information can lead to poor judgment and bad outcomes. OP: you'll get far more BS on this forum than good advice, and if you're largely ignorant (like me), you will need to work (sometimes a lot) to figure out which is which. |

I understand you have more education in this area then I do. I'm just recalling what I've read here years ago about why Crawford added coolant to their tank. From my layman point of view, driving many miles in Winter temps in colder climates, things tend to run cooler when they are not directly part of the engine. I assume the air temp in the engine bay in January when the outside air temp is single digits makes a difference on the skin temp on the AOS tank. (?) If it makes a difference my typical Winter drive in those temps is 145 miles one way to VT to go skiing. Just trying to add different things you may not have thought of, but again I know not everyone's driving style and conditions are the same. |

Looks like the v2 Crawford AOS had the coolant loop and then they decided to go without a coolant loop for the v3 model. Perhaps they decided it wasn't necessary.

When I did my research, none of the manufacturers addressed the hazard of getting water dumped into the oil directly, but if you read the Crawford faq, it's clear that they understand that some people have had issues in cold weather. https://crawfordperformance.com/blog...oil-separator# NOT saying this will happen to you; saying it could, because it's happened to me and others. I have not pulled my AOS out, but I am avoiding short trips, and am adding an oil temp gauge and a block heater for winter use. |
