Remember this curiosity from 13 months ago? (Probably not) It never
leaked again until this week when I found one of the oil cooler hoses
has a split in it. I bet it was a tiny split 13 months ago and the
weakest point in the system. I know I looked at that hose back then
because it seemed to be one of few things that could leak in that
area. That poor little hose is in a tight spot right next to the
exhaust header where it attaches to the head.
