You need to clean out or replace the crankcase breather.
It is normal for the engine to run poorly with the oil fill cap off.
The oil in the plug well is due to an old hardened valve cover gasket.
Just bring it to a mechanic and ask for a valve cover gasket and new crankcase breather. __________________ ...
