Recurring but not periodic tick Sign In

My apologies for the poor description of the noise.

2003 Chevy Impala, 3.4L V6. I don't have the mileage figures in front of my but I can go get it necessary.

Was driving yesterday and within 10 miles the check engine light came and on the engine starting rattling.

Besides the engine seeming somewhat "loud" there is a recurring tick or knocking sound that doesn't seem to be at any specific intervals.

Here is a video I took so you could listen: https://youtu.be/id2W_qI2EHs

Is this car safe to drive to an AutoZone to get the check engine light read?

IDK - noises are tough sometimes when right there. To me that sounds like a real problem noise and think you should skip just code check and you decide whether to tow or drive to a shop that can do both code readings and diagnose the noise.
Do check fluid levels before driving if you do. Also just look hard at the belt or take it off and spin pulleys for one not right but sounds more than that but it that shuts it up for just a test IMO it's better news for the fix of what isn't right,

I agree. The codes are important but not at the expense of the engine by driving it there. A tow truck would be the smartest option now.

Sounds like rod knock...wow I wouldn't be too worried about the check engine light, but figuring out if the engine is toast or not.
