well, the Leg has been slowly losing its refrigerant fill over 5 months or so.

 

asked an ex-alfa romeo mechanic friend where is the place that most likely leaks and he said check the accumulator first...

 

bingo! the top of the accumulator/drier is indeed all oily from losing the gas that has oil mixed into it.

 

OK, but where is it leaking from? is this the accumulator itself that leaks, the glass sight seal, the electrical sending unit (behind left tube in pic) or are those the o-rings for the pipes?

Friend was never into a/c fixing so couldn't give me more info

 

accumulators/driers are supposed to be cheap but why change something if its good?

 

will most likely de-pressurize the system and check but any info on the subject could be useful,

 

 

Grazie mille

Wipe off all the oily crud to see if you can visually spot the leak. If the system still works, look for bubbles at connection joints to pin point the leak. More then likely, a "O" ring is bad, and the source of the leak at a connection joint.
