I did an oil change and after that when I started the car a loud knocking sound happened. its coming below from the oil pan but you can also here it above. I,ve used a hose but nothing came out from the top of the engine. it all came from the bottom were the oil pan is located. what could this be???
my worry is might be the connecting rod bearing. but why???it was running very good before I made the oil change.
