The unloader circuit needs to work properly for the compressor to work right. I think you need a check valve there.

Some compressors (i.e. cheap compressors) don't have a unloader valve, they have an actual small pinhole in the piston top and that acts as an unloader.

Not putting miles on your car is like not having sex with your girlfriend, so she'll be more desirable to her next boyfriend.
