Hey guys, after doing some spirited driving here in Nashville this afternoon, I noticed a slight ticking noise coming from the engine/rear of the car, its not specific to any side I checked.
I have a pretty loud exhaust so I'm not sure if its ticking when I'm driving, but I noticed it when I got out of the car and it was idling. It ticks like the tip of a screwdriver hitting can, or heavy rain hitting a metal roof, so its high pitched and tangy. Additionally, theres no set pattern to this ticking, it could be ticking consistently once every 1-3 seconds then stop for 30-45 seconds, then go on again, then stop for 20 sec, and start again...
I did notice that the ticking got more frequent when I had the car in sport mode (since the idle revs are a little higher).
I've see some other forums mentioning "ticking noises" but those were mostly the injectors making that noise and this is definitely not that.
Anyway, here's a link to the youtube video
I recorded after I noticed the ticking issue, (would recommend turning volume all the way up).
It could be a few things:
- Muffler/Exhaust system
- I need to replace coil packs and spark plugs soon, could be that
- Serpentine belt
Is this something serious? Should I be worried?
I haven't found a forum thread that has this same issue, so if you've experienced this, or might know what the problem is, any insight is super appreciated.
