I am not sure if this will help. I have a 912E and occasionally (about every 12,000 miles) I get an oil leak from the area you specified. It leaks from the top of the oil pressure sending unit. It is an annoying leak but, not tremendous. The replacement part costs about six dollars and takes about 15 minutes to install. Although the 912E is a type 4 engine there might be a chance something similar is going on with your engine.
