I started the day by trimming the engine baffles to the contour of the engine cooling plenum. Next I riveted the aft left baffles together and riveted the oil cooler opening doubler plate. Lastly to see how the clearance was between the engine cooling plenum and the spark plugs I installed the ignition harness for the upper plugs for cylinders one and three.
