Slobber tube - cheap fix for blowby

[Gregory OConnor]

Shane, Sounds like a good plan with a 4 inch open container. I wonder
if there is a way to cut a vent on the trailer hitch side of the pipe
one inch below the bottom of the cut slobbertube. that would
eliminate the chance of the catch basin from filling and blocking
the discharge of the vertical slobbertube. Above the barb is where
the scum may hook and buildup. If the sump hung independent of the
tube????

The now and then service requirement is where I often fail.
