Hubbell 69HAU3 compressor cycling

The unloader valve was cycling the compressor so as per the instructions on this page I determined it was a bad check valve. I changed the check valve with a brand new one 2 months ago and it worked fine. Now the unloader has started to cycle the compressor again. Thoughts?

It is a Hubbell 69HAU3

When the compressor is stopped, is air blowing or leaking out of the unloader valve?
