My car sat up for a few years and now that I have it running again my P1SC headunit is leaking oil. I mounted the blower to my bench vice and filled it with oil and the only place I see oil is the front cover/gear case joint. Is this definitely the o-ring leaking? I already have an input seal I’m going to go ahead and replace. If it was the compressor seal, where does that oil usually show up? Any help is much appreciated.
