I had the same thing. There is a oil pressure gauge leaking causing it to drop right on the exhaust. Go get a Oil pressure sending unit about $7. Real easy to repalce and it will stop the smell. Might want to do a engine bright clean to get it all off. You should see oil pooling on top of the transmission.
