Hey guys, I bought a 2002 s2000 about 3months ago, sounded awful when warm, took a chance, brought it home. Had a full service done on it and had the valve clearances done. Runs really well now apart from this strange rattle. Doesn't do it on cold start up. If you let it get hot, turn it off and re-start it after about 10-15minutes it makes a weird rattle/ticking noise which then disappears after a few seconds. Any ideas on what it could be? Thanks!

 

Could be the TCT if it sounds like a card in bicycle spokes. Search for videos on it, it's a common sound.

 

Yea it's most likely the TCT. Get a Billman TCT coz it comes with lifetime warranty.

 

Thanks guys, thought it might of been that but thought it would of done it from cold start aswell or not?

 

Nope, TCT sound appears after you drive it cold, then it heats up, then turn off the engine and start it again (sounds when hot)
