Heard a loud bang lost throttle pressure it started to vibrate I changed my spark plugs and wires cuz some spots melted together she still starts up vibrates when I hit the gas oil is leaking from the driver side can't really pinpoint where as It is running down lines but only when car is running so idk this is my first car I love her and just need some ideas was told could be engine mount which is y I'm getting the vibrating and possible ripped the oil line when the engine came back down could have pushed a rod through the pan or block itself I have no mechanically knowledge I can only do paint and body and install speakers cd players and tvs in cars ne help would b grateful
