Paul, Larry,

I crawled under it tonight and it is definitely leaking from the rear speed sensor. No way to get at it without removing the whole compressor from the car, so it will have to come out. Should I just fix what's broken (the o ring) and leave the rest alone based on the inspection? Nothing else should be replaced while I have it out? Car has 150k on it. I plan on replacing the dryer/receiver since the sytem will be apart

Paul, where are you obtaining these great photos from?

Thanks again.

Tinker
