Defender 300TDi vibrations

Hi Evrybody

I have a little vibration problem on my defender 90" from 97. i hobe you have the solution to this problem-

I have changed the four rubber dampers under the airfilter and now I hav a some nasty vibrations from the under the bonnet when the engine is running idle speed.
I have tryed to put some rubberband around the airfilter, with no result

I hope fpr som help in here

And sorry my poor English, I'm from denmark

best regards

is it the filter housing rubbing on the bonnet? were the rubber dampers the same length as the old ones?

Have you tightened it down too much so the rubber isn't working like a damper?

hi again

it's the filterhousing ther maks the vibration, when I push it sligthly toward the engine I can make it stop
the rubber damper are same legth as the old ones-
and when i give the engine some rpm the vibration also stops.
I wonder if the filter housing can be moved back and forward for a better position

best regards and Merry christmas
