Hi,KeeneBolter! You say that you hear the noise,(with "stethoscope"),coming from the oil pan? Then,I'd drain the oil,look for shavings,and drop the pan. It's really a simple procedure. It's a good thing to do,anyway,with an engine that's been sitting for several years. If the P.O. didn't grease the crank and bearings,during engine assembly,condensation could form between the crank and journals,causing rust/pre-mature wear, to one or more bearings. The more you start and run your engine,the more wear you're causing. Once you drop your pan,check every bearing for wear/scoring. Use a plasti-gauge to check clearances. When re-installing bearing caps,make sure to torque cap bolts to required spec's. Make sure your oil pump is functioning properly,and the pick-up screen is clean. If bottom of pan has sludge,check for metal shavings. Wipe pan out,and clean and rinse with gasoline. Let it dry thoroughly. I prefer a cork gasket,for oil pans. i Permatex the gasket to the block,and i use "Vasoline" on the pan. That way,I save the gasket,if I need to drop the pan in the future. Hope this helps. GOOD LUCK!!
