I suspect the oil seep ( leak) on the front seal of the Delco rebuilt A6
OEM dash air conditioner compressor could be considered excessive, small
or normal based depending on which local A/C repair shop I'm listening
to. I had the unit install 3 years ago but now I've noticed a drop of
oil clinging to the underside of the lower radiator hose directly below
the compressor's clutch and seal area after the coach has been parked
for about a week. The hose is oily and there's the drop but no stain or
puddle on the ground underneath. So its not like the oil is dribbling
out. Of course there is some oil splatter on the underside of the cab
flooring overhead. I really was too concerned about this oil before,
but now I've noticed the freon reciever/dryer sight glass is showing
signs of freon under charge by the continuous stream of bubbles present
with the compressor running. The system is still producing cold air
from the dash so I'm suspecting the leak at the seal is small,
relatively speaking. Since I still have a supply or R12 available, I
plan to have the system charged with R12 to replace what has leaked
out. I've been advised by more than one A/C repair shop not bother with
replacing the seal and if the leaking oil bothers me enough that I
should put in another rebuilt compressor, the cost being about the same
for the two jobs. However, I'm also told that the A/6 is noted for oil
leaks at the front seal and that's why there are no long warranties
given on them. What I am wondering about is how I will know when and
how much oil will need to added to keep this compressor operating until
I can figure out how to replace the A6 in the future with a compressor
that doesn't have the reputation of leaking front seals like I've been
told it has. Has anyone on the Net ever reasoned what's the best
approach to managing this sort of problem? Thanks.
