I sealed a few internal case bolts per Kerry's recommendation. Also removed the oil pan and sealed the screen flange, case, and pan with Permatex 2B, as it was seeping very slightly. Fired up the engine.....and the leak is still there. Pulled the engine, removed the gland nut and flywheel...I'm getting really good at that. I've eliminated the easy stuff. I now fear that the problem is due to a case leak and I'll have to open the engine and reseal the case halves.
Update: I've determined that my cam plug is leaking. It looks dry, but it's actually leaking under the layer of RTV and seeping out below. I'll need to open the case and reseal the plug.
