P30 Aerovee Engine Installation.
Oil Cooler.
I fitted the oil cooler to the mounting flange. I located it where it would not hit the exhaust manifolds. I had to notch the forward flange to match the hole for the oil drain / oil temp plug. I drilled the holes to attach the oil cooler. I cut out the area for the air to flow through the oil cooler. I only cut three sides of the opening so that I could bend the cut out piece to make the air deflector. I used a piece of cardboard to try to determine where I need to notch the air deflector. I bent, cut and filed to get the air deflector to fit.
