Hi folks!

Can anyone help in the identification of a fart noise i have on my twin
point.
I have just put an avonbar extra hard engine steady bush kit on the car, at
the same time i needed to take off the air filter box and the odd hose to
get hands and sockets down to remove the steady bar and fit the new bushes.
After that the car seemed to exhibit some vibration thru the floor, i
guessed that this was due to the new bushes, the vibration occurs when the
car is stationary and is okay until i hope the bushes wear a little and the
vibes stop.
BUT!
When i am driving the car accelerating up a slight hill in 3rd or 4th gear,
the farting noise from the front is very noticable.
I have changed the air filter O ring, i have replaced the canister gasket on
the bell housing and checked the hoses that feed into the breating system,
but the noise is still there, i have even dismantled the air filter box and
put it back together, but to no avail.
The noise is very reminisant of a mini without an air filter, so the only
thing i can think of is that the noise isnt air at all, but vibration thru
the bulk head from the engine running at a certain rev in certain driving
conditions.

Any other ideas?

Jono
