Bravo! -
After the discussions, being Sunday today.
I Lifted the HOOD, as if am really going down the engine myself thru the radiator and diagnose the problem as in endoscopy probe.
a close inch by inch inspection revealed a seeping oil leak at the distributor oil seal, a bit of rust at the Top hose clips, but - the most important is....! oil moisture on aircon tubes, tracking all tubes back to compressor,
It is damn Aircon compressor FQIN up the power & heat up.
It has some oil moisture and yes the cooling was a bit low then usual, since summer started.
so suggest what more before I call for date with aircon shop
still need some more input,
Thank you all
