I changed to Amsoil last oil change. About 1,500 miles later my car started developing this slapping/tapping noise when it is idling. It is loudest at cold idle and can still hear it at hot idle.
For a few weeks it was doing it everyday, so I took it into the dealership to get looked at. They told me they couldn't hear anything. I took the car home and now it only happens some mornings, not every morning. I can still also hear it sometimes at idle. Sometimes its loud enough at cold idle that I can hear it about 50ft away.
It seems to be coming from the bottom of my engine. I can't tell if its driver or passenger side but I'm thinking driver side.
I will have a video of it up as soon as I can. Anyone else have this issue?
I would like to get this figured out asap because im ready to start modding!!!
