I was just going to find the hemorrhagic oil leak and fix it. Things escalated. I'm sure there's more crap in my parts bin I've forgotten about. We'll see what else comes up while I'm in there. Great time to strip and refinish all that tin, but I'm lazy and this is a driver. Call it patina. I just don't know how I'll be able to trust that there are any fluids in it when it stops marking its spot.
