07 loud rhythmic ticking

[darceydo]

Sometimes on cold starts my 07 will have a loud rhythmic ticking/clicking coming from the bottom DS of the engine/wheel well. It only happens once in a while and if I restart, it goes away completely and engine sounds normal. Other times when I don’t restart it goes away after driving a bit. Any ideas here?

Exhaust leak? Mine has about 3 and cold she ticks a bit that's for sure.

Or more seriously, loose spark plugs potentially working their way loose. Best to check em and snug them down.

Check yer spark plugs.

^^^Easy enough. There is a good thread in the 100 section concerning this.
