Uh... umm.... well, I was kinda gonna blow off this step since I replaced most of the major parts, but I'm guessing this is not a step I should skip-?

Is there really that mich crap built up in there, and will a blow- whoops! I mean vaccum- job really take care of it all? ( Sorry, couldn't resist).

What's this cost to do, as I know I haven't go the resources to do this myself.

Also, anybody know how much R12 oil (Not ester, or R134-intended oil) goes inside one of these compressors?

I've also read (anecdotal accounts) that I'm supposed to add oil to the reciever-dryer, but I can find no information as to how much. Anybody know?

Thanks again,

Gil
