Hi,

I'm looking to buy a s2000 and I've seen one, however it's making a noise, which I haven't heard before. The cars had the TCT done (2k ago), but the noise (around 4 seconds onwards) is sort of a popping noise. Any ideas what this can be?

Thanks in advance!

 

How does the noise behave as the engine rpms increase? It doesn't sound too healthy

 

When revving the rev counter seemed fine, it was just the noise when recording close up to the engine?

the question is, what's the worst it could be?
