What liquids go in to your catch can?

What fluids do you have going into your catch can?

• I put a 360* loop in both differential vents, so they aren't going into my catch can, and I haven't been busted yet. (fingers crossed)


• My power steering has an OEM cap - not vented into my catch can


• Brake reservoir - nope, not going into my catch can


• Washer fluid? Nope. Fuel tank? Not a chance.

I've got the transmission, t-case, radiator, and crankcase going into my can.
