Engine gurus: what the heck is this sound?


Recommended Posts

All engine gurus, I need help.

While checking my parking spot today I heard the strangest sporadic metallic rattling from the passenger side of the engine. I could not really localize the sound (hoping it was from the cats maybe, and NOT the engine itself). It sounds ominous to me.

The car just had 2 new coil packs and 6 new spark plugs installed, and is otherwise running GREAT.

Here is the sound... you hear it right away (sounds like Im starting the car, but its just the weird sound), and then again at 9 seconds or so...

Any help TRULY appreciated!

sounds like the guts of a cat tumbling around, but hard to tell. whatever it is, my friend, it doesnt sound good. dont risk it. get thyself to the garage.

ps: still love that Orient Red car of yours. hope this is not really serious. interested to know what this turns out to be. jl

I had almost the same sound and it was one of the cats. I got a post 02 out of spec code at about the same time.

Note that when I took it into the dealer, they ended up replacing the engine FIRST, then discovered that the noise was one of the catalytic convectors... That's a whole other story.

I'll second the cat notion. Its hard to tell when you're not there in person but a failed cat makes a pretty distinct sound and that sounds pretty close. Depending on what year car you have you may still be under the federal emission warranty.

Thanks to all of my "online mechanics"!!

It seems as if the consensus is an issue with either a loose heat shield (perhaps not

tightened after coil pack install), or an problem with one of the cats.

I will have it checked by my Indy asap. I needed front brake pads and an oil change anyway...

If it is one of the cats, and they are no longer in warranty (no cel), then it might be time for cat bypass pipes?! :)

:::closing the loop:::

I crawled around banging on parts with a rubber mallet, and found one of the exhaust hangers was loose...

After some contortionism I was able to tighten it... Voilà...

Noise gone!

It's hard to believe a bolt with only a couple of turns of play could make that racket!

Thanks to everyone!
