A/C Condensor possible leaking with pics

[puddinboo]

I have no A/C ,also checked high and low sides of A/C lines with manifold gauges= 0 pressure. Also checked with a screw driver at ea valve no pressure not even a hiss.
So my conclusion is the condenser has leaked and can see a greenish color oil as seen in pics. It not thing like antifreeze.plus my coolant hasn't lost a drop of coolant in a few years.
I would like someone's opinion on this.if you can tell by looking at below pics.
I'm thinking of replacing the condenser, O rings,and compressor.Since there is over 250000km on it.I realy don't want to replace the evaporator .

Thank you.
