This only happens when the car sits overnight and it's in the 60s outside. After like 20 seconds or so, the noise goes away. You'd never hear it if you don't pop the hood. Anybody know what's going on?

 

sounds like TCT to me... like something was hitting the spokes in a bicycle wheel

 

Definitely tct noise. Thanks obama!

 

Tct 100%.

 

Excellent sound example of TCT; someone should link that video in a TCT sticky!

 

I did another valve adjustment and made damn sure it was perfect. Still makes the noise. I thought the tct noise was only when the engine was warm?? After like 20 seconds it goes away as you can hear in the video. I'll be blasting my tct soon (as soon as I can get the bolt for it) and I'll let you know how it goes. Ive been stubborn as hell when somebody tells me it's the tct just because that's the go-to answer for anything s2000 engine noise related, but it's worth a shot. Could it also be the starter sticking?

 

This is not a guess, your noise is tct I assure you. For you to have noise at that rpm and pressure, sandblasting will not help. I have a permanent fix in my sig above...

 

gotta love humour..




respects Jacob, this gentleman expressing it is TCT, might very well be the leading authority on the subject.. just a hint.. your great, we all love tearing apart our cars.. but.. just cracked me right up, so I had to respond... ... I've screwed up enough cars in 53 yrs working on'm...

 

He's probably gonna be happy when he gets a new tct installed because the noise will be gone, but damn pissed off it was actually the tct lol.

 

^^^ Yep. I was trying so hard to not let it be what EVERYBODY told me it was and I ignored.

Billman, I'll be ordering one of yours I guess. You are the expert when it comes to this... Thanks for the insight.
