Drove Peachy down to AAA last week... Parked between 2 newer MB's...
While the car is waiting for the new owner, it's been sitting in the garage...
And I noticed an oil spot under the front drivers side....
And investigation showed a leak in the AC pipe joint there... Pulling out the UV light, I could see evidence of the flourecent dye I put in when I recharged it.
The AC was still blowing cold, but clearly it was and is loosing freon and a little oil...
After discussion with the new owner, I decided upon a course of action, as i have the tools, supplies, and time to fix it before the hand over.
Evacuated the system...
Next I replaced the O ring in the leaking joint with a new HNBR ring.
The old one was hard, and split. It was clear the rest would not be much different.
Running a Vacuum and leaving it overnight, I saw a drop of about 4" in 24 hours... Clearly there are more leaks.
As I had already done the Receiver/Dryer O rings, so it seemed logical to do the rest.
Low side joint was next.
Then the Expansion Valve..
The UV lamp showed signs of leakage here too... you cant see it with the camera..
Pulled it out, and it looked clean, with no signs of clogging or black death that I have seen before.
The O rings on both sides were old, compressed, and brittle.
Replaced.
Front end rings were the same...
Done.
Last one was the this one into the condensor... tricky to get at and photograph!
Again, the original was old and hard.
Done.
The only ones left were on the back of the compressor...
It has to come out to do it... a PITA, but has to be done...
Cleaned it up while it was out.
Replaced the O rings.
So, it all back in, and for the last 48 hours it has been sitting under 30" of vacuum, with no change.
