Using a freon leak detector to find some freon leaks on my 82 XJ6. Found one at the receiver drier Easy repair
But my detector is screeching at the rear of the compressor. I know there is 2 o rings where the hoses connect. Are these available? Part number?

Also it appears I may have a leak at the pressure relief valve screwed into the backplate These seem to be NLA.. Anyone had a leak in this part and can they be cleaned or repaired.

 

The GM number is 2724674

Bit there are lots on online vendors....

Thanks Doug

 

What do they mean by Metric Compressor in the Parts Manual starting around 1981-2 vs the other A6 type used previously.

 

It just means metric mounting fasteners were used
