Engine sound - what damage is this?
I was having a fun drive, probably pushing it a bit much. when i came to a stop i noticed the engine sounded different and maybe even had some reduced power.
I changed the oil and saw nothing out of the ordinary and nothing on the drain plug. Oil level was fine too. I have not cut open the filter yet.
I have not taken the valve covers off yet as that is kind of a pain to get to.
Any guesses as to what this sound is?
