OK so I had this with WoKzoo's CRV. There is something bolted to the side of the block that is a known leak problem. But I don't remember what it is. Her CRV developed the leak and I checked on the repair. Simple enough to DIY if you have a lift. As I remember it was 2 10mm bolts. A 5 minute repair. Checking with the local Midas shop it was $75. She totaled that CRV before I got it fixed.
