New AC Compressors Leaking

[mbboy]

I installed a brand new Delco A-10 style compressor in my 380sl last April, and it was leaking from the rear seal immediately. So, I returned it, and got another one, which I installed last May.

Even though I hardly used that one, I was shocked to find that it, too, is leaking from the rear seal, just like the other one was. And as far as I know, I didn’t do anything that should have caused both compressors to leak.

Before I go and replace this one, I was wondering if anyone could tell me whether it’s possible that I got 2, brand new, Delco compressors that leaked, or whether I could have done something that caused them to leak.

Thanks very much in advance for the help.
