Probably water.
I haven't had a problem on my truck till I added these dirty DDP 75s.
My buddy had a BOV at the start (same as the you-tube vid truck) and he never had a problem besides the usual draining. But he had Mach 7s which are really clean.

So basically the dirty/hazy trucks are going to make lots of moisture/water.
Been thinking about trying a 2nd water trap, just a simple mini-industrial on the cold side of the drive pressure line.
