Webster Air Vent blowing steam

Looking for some guidance on a 2-pipe steam system.

I have a Webster vent/trap (marked “0023 ATV” on the front) that recently started blowing steam out of the top. This began shortly after a contractor modified the wet return.

Originally, the wet return ran straight into the boiler. It was re-piped lower, creating a U-shape to get under a set of steps that were built. Not sure if that change could be causing this issue, but the timing lines up.

My questions:
– Could the wet return modification be causing this vent to pass steam?
– What is the proper replacement for this Webster unit?
– Can I replace it with (2) Gorton #2 vents on an antler, or is that not appropriate for this setup?

Appreciate any advice.

    shouldn't be steam in the returns.

    need to know more about how this pipe was changed, was anything tied together higher than it was originally? if it was truly a wet return and was just a pipe with nothing connected to the section that was changed, going down then back up shouldn't change anything.

    did you skim the oils from the new pipe off of the boiler?
