Just called ARB, holy cow their tech support is impressive. Got a real person on the line in like a minute.
Anyways, they guy basically said that what I was was probably gear oil and air being displaced by the piston as it moved, he said run it.
He also said that my gear oil out the solenoid issues are clogged breathers. I rerouted them a few weeks ago so maybe that'll address that.
Now to call Poly Pro.
