We spent a lot of time trouble shooting this. My buddy decided to hire an AP on the field to take a look. He tried to remove the oil galley plug on cylinder #1 and stripped the hex. He tried drilling it out for an EZ Out and the EZ Out broke in the hole. Hired another AP who specializes in power plants. He managed to get the plug out with not too much damage using a torch and special tools he had and hooked up an analog pressure gauge to that galley port. Pressure was good. Wanted to test the other ports but not willing to risk stripping those plugs out, then we would have to remove the engine to get those out. Called Superior engines and found out that when they built the engine, they used Permanent Loctite when they install the galley plugs. We removed and checked all the oil lines for the remote filter, pressure manfold, and oil cooler. All free and clear including the oil cooler. Reassembled and tested again. The manifold port between the remote filter and oil cooler still reads high with the Dynon sensor, but reads normal when installed on the oil galley port. AP was confident that oil pressure was not a problem. Issue is probably caused where the manifold is located due to various reasons we don't understand. The BM transducer and Dynon transducer operates differently and are not compatible. Anyway,,,,everything is good now after paying $600 in AP work and he's back in the air flying the wings off that Cozy MKIV and enjoying his new Skyview panel.
