I have a very annoying vibration or resonating prob , when i get between 1.5k and 2.0k this horrendous shake takes place , does anybody know what it could be?
I have had the car on a ramp to find it and i just cant see what it is , nothin seems lose anywhere .
I have a feelin it could be just simple like an exhaust vibe , or maybe the viscous fan is sort of out of balance , but i dont know how to check it out ! !
All suggestions greatfully accepted

Cheers Jibbers

Engine mount is the most likely source of the problem but as said above check the prop as well.

Cheers guys , have checked out the mounts and nowt seems to be wrong and as for the prop , it could only be the centre bearing couldnt it ?
Surely if this was shot i would get the vibe right through the rev range , in fact cancel the last point cos it does it in neutral when the prop aint movin , so thats not it !
I was thinkin more along the lines of some sort of engine related prob , maybe the viscous fan ?
Im not sure if its workin right , i.e when it should be spinning , or not !
Its not sumfin i know much about , is there any way to tell if its broke ?

Have noticed a small , well tiny blow on exhaust , but this wouldnt be felt through the pedals and seat would it ! !

Are you sure it couldn't be a misfire? Would quite likely shake a fair bit if one of the cylinders wasn't firing...

& if you think it's the fan, take it off & see if it still does it!

The exhaust could have come off one of its mountings and may be touching the underside of the car somewhere and causing it.

Nothin missin anywhere , the prob isnt there right away either , after about 5 mins it starts and gets louder as the engine warms , thats why i thought it was maybe the fan , what is it supposed to do and when , i heard it had some kind of clutch in it , is this true ?

i doubt its the viscous...... misfire??? mounts?? exhaust?? does the clutch feel normal....

is it only rev related then not speed?

if speed its almost 100% prop related....

does engine pull like normal or does it feel weak?

dont reckon its the mounts , there is not a misfire , it does it even in neutral , i have just put in a new clutch as i thought this was the prob !
It pulls very well , maybe it is the zorst ressonating , i just dont know ?
