When start the machine after few seconds compressor starts spitting hydraulic oil out the air hose.
I replaced the filter and hydraulic oil.
Even full or low on oil it continues to split oil out, everything seems to be working pump wise.

185 spitting hydraulic oil
You changed the filter? As in separator filter?
If you changed the separator, then maybe your scavenge line is clogged. Probably, even.
Check it out and please let us know.

Could what you’re seeing now be residual from earlier?
Is your sump oil level dropping?
Maybe overfilled?
