Buzzing Wierd Noise In My Engine!! HELP PLEASE! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Twinkie · 05-28-2004, 04:20 AM

Lately, I just got a stage 2 kevlar/copper 6 puck clutch installed into my s13
sr20det engine-tranny. Now that ive got the new clutch, I thougth everything would be cool. Until I was driving down a highway, then I hear weird ass buzzing sound coming from the engine at 4th gear when my foot is off the gas pedal.

It sounded like a rubbing friction sound.

But this sound goes away everytime my foot is on the gas pedal accelerating at 3krpm or higher. (The sound also goes away right when i push the clutch peddle down while still in 4rth gear). As I take my foot off the gas pedal when im still in 4rht gear, the buzzing sound comes back at around 2700rpm. When it passes down below 2000rpm, the buzzing sound goes away again. This wierd ass sound ONLY happens on 4th gear.
1rst, 2nd, 3rd & 5th = OK. 4rth = WTF!?

Im not sure if it is my clutch or my tranny. It might be something fromt he engine, because i hear it behind the dash through the AC/Heater opening. But as of now, im afraid to drive it, and hoping I dont need to go fix it again and burn a hole through my wallet. PLEASE HELP!!

Same thing happened to me. I posted a thread about it not long ago and everyone came to the conclusion it was the driveshaft out of balance for one of many reasons (not reinstalled in proper rotation on the dif, weight came off, etc). Buzzy chattery noise between 3000-2000rpm on decel only right? Happened to me right after my clutch/flywheel install...

Hmm. Thanks. I read your thread. I have almost the same exact problem, but ONLY IN 4th GEAR. Im restricting myself from driving right now because i dotn wanna jack anything up in the tranny. But im leaning towards your problem. SO how did you fix it anyway? Was it expensive? Would if hurt my tranny or drive shaft if i still drive it? Or should i go fix it immediately?

they dont call it a throwout bearing for nothing

I dont think its the throwout bearing. I mean...It might be, but Im pretty sure its not. I got the throwout bearing changed a long with my new clutch.

My main concern right now is if its really gonna hurt my car if i still drive it, because ive got errands to run haha.

Any one out there that can help me??

An auto machine shop or maybe a transmission shop should be able to balance your driveshaft. Im planning on getting a new differential a little down the line so until then im just dealing with the noise

Mine has done the exact same thing for 6 months. It causes no damage - just an annoying noice. You can try rotating your driveshaft 180 degrees by unbolting it from the diff. It didn't help me though. I'm just gunna live with it until I can get a 1-piece aluminum. You can also learn to "drive around it" so it doesn't make the annoying noise.
