The compressor is leaking...again. I'll remove the compressor tomorrow early
in the morning and they'll fix it under warranty. And, while down there
reassembling the cat converter, found me a nice oil leak coming from the oil
cooler (and the hits keep on coming). I'm thinking the cooler's o-ring
failed, causing the leak. Ain't Vanagons grand... Oh, well, gotta love 'em.
