Hi all, on my 2007 Azure, I'm getting mineral oil leaking out from the lid of the reservoir. We just had the rear springs replaced so I suspect it accidentally got overfilled. A couple of questions here. One, is it designed to overflow from the cap? I wouldn't think so, but I'm not an expert. If it's not supposed to do that, then I think I need to replace the rubber o-ring gasket that's in the lid. Looking at mine, there's a flat side that's up against the cap and the other side of it has a bit of a groove in it. I'm not sure if that's supposed to be there or not. I'm having trouble finding the part number or a source for this gasket, though, so does anyone know what it might be?
