my car sounds like a diesel

I know at least one of my motor mounts is bad but the noise seems to be coming from right under the plastic cover (from the engine). Is this normal?

[sstroudwku]

no that is not normal. It sounds like a wrist pin "pin that holds the connecting rod to the piston" or a cam lobe slapping lifter/tappet/cap depending on what you call it. It's hard to tell from the video though. Check the oil as well. Any check engine lights? Running s*** gas?

[Hussain]

no check engine light. I used to use s*** gas a couple years ago but for the past year I've run 91 from Costco. I checked my car again today and I didn't hear any unusual noises

So it only happened that day?
