My apologies to everyone for spamming the list so much lately.  I'm trying to do my research before asking the list, but sometimes my google-fu isn't exactly fruitful.

Anyway...  Oil filled caps in our gear.  Was it standard to denote whether they contained PCBs in them, or is it a safe assumption that ANY oil filled cap with a manufacture date before 1980 is suspect?  As most of those are likely out of spec and leaky, is there ANY way to open the cap, dispose of the contents at an EPA approved site and then restuff the shell with new components?  Or is my only recourse to decouple the old cap from the circuit and then place newer ones under the chassis (or try to hide them, etc).  If my only option is the latter, once decoupled from the circuit, what's the likelihood that it will actually start leaking (as in, the oil).  One would think that would be fairly miniscule, but what with some of these going on 80+ years old, it's a crap shoot at this point, no?

Thanks again
