So, the other day I began hearing the rattling noise at low rpm/idle again. It seems to be worse at low rpm, btwn 1-2k, than at idle. I immediately rushed into the engine bay and looked around trying to decide where it was coming from.

I looked at the header heatshield.... and one of the bolts is missing. I think that *maybe* what I thought to be the TCT acting up... might just be a missing bolt.

Does anyone have any insight as to the most common places these bolts could get stuck and hang out? I'm going to be digging in tonight until I find it, even if it isn't the root of the problem. Otherwise, the car goes to the dealer on Weds.

Thanks for any input!

 

once there was a noise coming from the engine on mine, but I looked around and traced the noise to my stock o2 sensor, it was a little loose and I tightened it and it went away.. I think it was just rattling back and forth making a tapping sound..
Just a thought if its not ur tct

 

Adding that to the list of easy things to check... thanks for the heads up

 

Also, try using the search tool to look up tct ticking. There are a couple sound clips here on the forums. Double check if that is your sound.

If not, Try google video or youtube. I have seen some clicking sound clips on there as well, although I would not use these as good resources.

 

I've researched the crap out of the TCT thing on here... to be honest, my rattling noise doesn't sound as loud/pronounced as what I've heard in sound clips. From some of the clips I've heard.... its a pretty regular occuring sound. Mine... is somewhat irregular/unpredictable. Another thought was low oil (its been about 3000 miles, and it appears I might have burnt off a little.) So, thats another thing on my check list.

Thx again~
