i think i have a freon leak, but my H-10B cant seem to find it...

that said i added freon to the system till it came out of the vacuume it
was running in, only a couple ounces...
here are some numbers:
box temp..34*
return gas temp..83*
discharge temp..178*

8/180 psi

customer told me this unit is on its 3rd compressor(aea4440yxa)
filter is hot (032)

could i have oil in the evap and or the condensing unit?

this bevaire keg cooler will run for 4-5 days then run warm from a leak..
im going to psi test the thing to get the leak to show its self and run a
cleaner through the line set

but..anything im missing?
