A/C oil leak
I've noticed some oil on the spring and cross member under the AC compressor on my '99 FRC. I have a lift and have looked everything over and cannot find any other place it could be coming from. The AC still blows cold. Is there anything I can do short of replacing the compressor? Thanks

Sure it's not your power steering rack or one of the hoses? I'd put the dye stuff into the AC and power steering fluid (probably P/S first), wait a few days then hit it with the black light. Also in my experience with the leaky A/C mine leaked out from the the compressor seals and under blacklight with the dye you could see it evaporated and left deposits in a ring shape around the compressor, but did not "drip" out. My guess is it's likely not the A/C compressor.
