Found by my mechanic during an oil change. The FF-00024 oil cooler hose fitting was much too close to a spring on the #1 exhaust. Do not know how long this condition existed. Have ordered a new hose assembly ($$$). As an aside, a local high school build is nearing completion, and their clearance at this location is almost non-existent as well. Mechanic has simply shifted the muffler slightly, which gave the clearance in the last picture below.
