Now I have two questions. My mechanic told me to drain the compressor and replace the oil with oil having die in it. He showed a plastic bottle of what he uses. I can't remember what type it is, what number, i.e., 100 or 150. was it peg or ether? I went to the parts store but didn't find what he had. What oil should I use, with die in it. The next question is about a vacuum line at the evaporator box. There's a canister mounted on top of the evaporator. Next the firewall there is a vacuum line coming out of the canister. It leads to a T.. From there one 1/8" line is blanked off. Another, bigger line goes back to the vacuum manifold. Where should the blanked off line go?
