Greetings Spiderman,

When you speak of oil in the crankcase of the York compressor, we are speaking of a seperate oil that is not under pressure that is poured into it aren't we? What weight is this oil, and where can it be gotten from? Do auto parts stores carry it? Secondly, if there is oil in the crankcase, then must there also be oil put into the freon system when it is charged? As far as the seals are concerned, do you think that the plastic or nylon seals on top of the York manifold are industry standard, they seem like they would only fit this unit. The last thing, is whether the York can take the increased pressures using R134 freon. Any input would be greatly appreciated.

Thanks,

Charles
