But would it hurt to throw oil back in it and run it to see if that “noise” continues?the low oil level light did not come on and the low oil pressure light did? an oil pressure light from low oil means the pickup tube is no longer in the oil fun zone and your oil level light definetly would be on before that because safety meassures.
if you drove it that long with no oil it doesnt matter how good a company is your engine is damaged. main bearings need oil piston skirts sneed oil cam bearings need oil. your engine rattles now right. that is probably your pistons scoring the cylinder walls. go to a shop
also dieseling and runaway engines are the same meaning reffering to hot spots in the combustion chamber causing the engine to continue to run after ignition is off and impossible on fuel injected electronic ignition cars
