I have an annoyingly excessive oil leak coming from what appears to be beneath my engine data plate. Then engine has about 650 hours on it and it appears to have oversized data plate screws. My biggest fear would be a crack beneath the plate but it seems unlikely. Does anyone know how deep those data plate screw holes are intended to be drilled into the case. Before I pull the plate, I thought I would gather some information from you all. I bet the engine was overhauled the case was drilled through all the way and one of the data plates attaching screws is not making a oil tight seal. If this is the case what would be your recommended solution? Any help is greatly appreciated. Please see below for link to the video.
