Bear with me here as when it comes to mechanics I am about as much use as a c0ck flavoured lolly pop.

Driving the S2000 today, everything was propoerly warmed up, and I took my foot of of the gas with the revs at around 7.5/8k and let the engine coast, at about 6k the engine made a loud buzzing noise that I can only compare to a black and decker saw going off. It sounds like something is vibrating?

Had the car for a while now, although it is not my daily runner so it does limited miles, but I have never had this before?

No other issues, it runs fine, no pops or misfires, in every other way it is running just fine?

Any thoughts?

Thanks

 

I had this noise its either your tct or you need a valve adjustment it helped mine

 

it could be the TCT ( timing chain tensoner ) or it could be the clutch disk buzz thats prevalent on my car ( stock and now with an ACT )

 

chainsaw sound= clutch buzz
card in bicycle spokes = TCT

 

lol only on our forum do people have such random ways to describe sounds, but they are so true.

 

Defo a chainsaw sound, so I assume a clutch buzz.

Does this meean time for a new clutch??

Thanks

 

nah. clutches in our car buzz. surprised you haven't heard it before

 

Another two for the sound table:

Loose Exhaust Manifold Heat Shield=Same as Chainsaw Clutch Sound but Higher Pitch
Sound seems to be coming from everywhere and can't pinpoint=Loose Spare Tire Nut

^^ Hey I will be in Ogden on March 23rd, any meets going on during the couple weeks after that? I'll be there until April 9th.

 

Hmmmmmmmmmm....it is higher pitched than the engine note?

Is this something that I can tackle myself, bearing in mind that I am technically inept. If it is a case of climbing under the car with a wrench, finding the bolt responsible and wrenching it tight, then I might have a go.

How do I locate the culprit......

Thanks,
