Vibrations? Help please - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Brians S13 · 12-26-2011, 09:09 PM

I own a 91 s13, and when i drive it..it sounds like the motor is way higher rpm than the rpm gauge reads and its vibrating pretty harsh. I looked under the car and im assuming the vibrations have made 3 of my drive shaft bolts fall out, so i replaced those..but can anyone please help with this situation? Thanks.

check your fan clutch. if it`s locked up, it will be really loud.

You need to be more descriptive.

Does it always vibrate? At certain RPMs? At certain speeds? When you do anything in particular? Stuff like that.

There's a lot of spinning shit in your car that can vibrate.

about 2.5 to 3k rpms it vibrates really bad to the point where my shift knob loosens..so i hurry and shift

If you're RPMs are ramping but you aren't going anywhere, it sounds like your clutch is slipping.

The vibrating sounds like clutch chatter. Watch this and let us know if this is what you're experiencing:

is it giving you a CEL ?

c_mancuyas8 · 12-27-2011, 01:52 AM

Does it only do it under engine load or in nuetral also? If it doesnt do it in neutral or at warm idle im pretty sure you need new mouts. If its shaking as bad as you say it may not be safe to drive.

Brians S13 · 12-27-2011, 09:44 PM

No CEL, and i'll have to check it in neutral tomorrow, im not sure

so if it vibrates in neutral my motor mount may be broken?

on my way from home from work today, i stopped at a red light and revved up in neutral..it vibrates just as much as it does driving, vibrations start at about 3k

Yah, I'd swap the mounts since its doing it in idle too...if it was only doing it while driving, I was gonna say driveshaft issue.
