what up guys i have a rpm dependent rattle it happens around 2k on but you cant hear it after 5k the car is too loud u only hear it with the top up but it is always there it sounds like a valve train noise i have been told there is a problem with oem ap1 clutch discs that they rattle between 3-5 k and were being replaced at the dealer to fix the rattle and others have said it may be a lower valve spring retainer has any 1 had a noise like this

 

Does anyone have the engine rattle around 4k? Usually loudest in lower gears. Im suspecting its the timing chain guide? Not 100% though.

 

U mean timing chain tensioner?

 

I just got my s2000 and I hear a little buzzing rattle that sounds like it's come from in the dash. Any suggestions?

 

I also have a rattle/buzz from the dash, right around 4-5k rpm especially if I give it lots of gas. It doesn't sound like its coming from the engine though, its definitely the resonance vibration that is causing something to rattle right where the radio head unit is (sounds like its coming from right behind it). Ideas anyone?

 

idk man, at 1st i thought my HFC was rattling.

tell me whatcha think. thanksssssss

 

Yup sounds similar to what mine did but as soon as I removed my hfc it went away.

 

ight, i pm'ed steve at berk's. ima see how this will work. thanks man

edit: brian sorry

 

reporting back. i removed the hfc and there isnt anything wrong with it. i tabbed it, shook it, seems intact. but the gasket that goes in between the cat back and hfc is rusting and falling apart, like dry rotted. this gasket (house gasket) lasted me about 2 years which came with berk's hfc. pretty good and durable, i guess.

ill add pics ina sec.

edit: here are the pics
