Hydro pump whinning!!

[dahmower]

I got my splitter built and fired it up for the first time last night the pump was whinning more than I thought it should and the oil was milky looking with everything being new I know no water is in the system. I'm gonna say it's air in the system?? How long until it works the air out or is there something else to do to it??

The time to work the air out should be really minimal....like a few minutes. Sounds like there is something else to it. Also, in my limited experience, milky fluid means water and foamy fluid means air.
