I have an N16 phase 1 1.8 sport almera and ever since ive had the car there has been a vibrating noise between 2000 to 3000 rpm only notice able an 1st and 2nd gea. I suspected it was coming from exhaust heat shields so i bought a new system and didnt replace the heat shields but this didnt cure it. The only other thing I thought it could be was the gearbox mount so I untightend it made shure the mounts werent worn out then tightend it back up and this seemed to cure it. But a few months later it started to make the same noise again but realy faint and has progresivley gone back to how it was before Is there anything I can do to sort it, some polybushes maybe or even replace the mount? or is it even the gearbox mount. Any help would be much appreciated
