    I thought i had a Bear in the engine bay

    Okay so the title is obscure...

    I had this horrendous growl in the engine bay bad enough that i booked the D2 into Roverland and stopped driving her.

    I found what it was yesterday, it was such a little thing that made so much noise, i bet no one can guess what the cause was.

    Story.....

    I went over a speed hump a little hard and then when ever i slowed down this incredibly load resonating noise occurred.

    At first i thought it might be a muffler collapsed and all the stuff vibrating away.

    It sounded similar to the noise a power steering pump makes when you are giving it hard time and the fluid is still cold but 2-3 times louder... It was damn loud!!

    "groOOWL!"

    All i could think of was $$$$$ and this doesn't sound good it must be the transmission or similiar.

    Now trying to figure out what the noise was i began the usual process of diagnosis.

    1. The growl happens on deceleration but it can also be heard on acceleration too

    2. The growl occurs at about 30km/h when the trans drops into 2nd when slowing to a stop

    3. Its louder when the motor is cold

    4. If you drop it in low range the growl occurs at approx 10-15 km/h

    5. I can also feel the growl under my feet through the floor pan

    6. i cannot pin point the location of the noise, it sounds as if it might be midway along the drivers side, but difficult to tell without being a passenger

    Can you guess what it was?

    hmmm, sounds like a wife growling cause you're "driving like a lunatic again, why can't you just slow down for speed bumps like normal people?"

    or busted engine mounts and the fan is hitting the shroud

    After pinching the flash spare tyre (see that other thread), the thieves pinched the air cleaner, creating much induction noise....

    (My X1/9 sounds very growly when the carby is open to the atmosphere).

    At a guess some of the plastic noise reduction crap on the D2's engine bay had come loose, say the rocker cover accoustic shroud needed the bolts tightning.
