The goldenrod is a filter. The clear base with a screw in element. You can get different micron ratings or a waterblock element. When the filter encounters water a chemical inside adsorbs the water and clogs the filter stopping the flow. You can see it. It looks like worms or something coming out of the holes in the element. From what I have read since I installed it, there are filters with more filter area for the money, but this works fine since I have it after the 5 micron filter just for water block.
The crackle test is when you put a little bit of oil on a frying pan to heat it. You should be able to get it hot without any crackling sounds. The crackle is the water boiling out of the oil. This tells you if there is any entrained water.
When I get cubbies with water in them the oil smells rancid, sour, like vomit. I don't know how long this takes or if it is the heat down here, but if it smells at all, it goes right into the trash can. Every one that has smelled, I pull the cubbie out of the box and it has water in it. I have a can settling for two months to see what happens, but in my opinion it is not worth the trouble. I toss it and move on.
I just realized we hijacked this thread. Sorry TopTech. TonkaThunder if you need anything else, PM me or start a thread. I would like others input anyway and this will not be found under an ATF heading.
