I’m finalizing the new cooling plenum. First note that I’m making a pop-up oil door instead of the factory style yogurt-cup bump down like I mentioned previously. This door will pop up into the cowling door and allow me to get my hand down onto the dipstick while also allowing for better airflow. Note also that I built a flange to hold the front of the pilot side runner down. This alleviates the need to have a nutplate down here near the cylinder. Finally, you’ll see that I’ve cut the openings for the runners and have started to reinforce all of the openings with Triax.
