gearbox noise - any ideas???
Turbo Mini Forums

hi there

my gearbox is making strange noises, i want to see if anyone has any ideas, that may mean I dont have to take the box out to look to see whats wrong.

the noise sound like a tapping noise, when in neutral, that sounds a bit like a big end knock, but disappears completely when the clutch pedal is pressed. I was thinking maybe a gear has a broken tooth?? dont really know....
I know i am going to have to remove the box, but thought someone may have a magic easy answer!!!

clutch bearing?

mine is making the same gets worse with revs??

It'll be drop gear related most likely. Sounds like maybe excessive end float in the primary or idler, could also be a failing nose bearing.

Needs investigation befor it self destructs IMO.

Just wind up the ignition advance a tad and it will go away.

when you get your head under the car it sounds like it is coming straight from the middle of the sump, i will get the box out over the weekend if i get the time.

I've got the same.
Changed bearings, adjusted idler end float, changed clutch and clutch bearing: noise is still here.
I think it's the clutch bearing, I've got exactly the same noise on the Maserati biturbo known to have this "problem".

Is there any whine from the gears (assuming a helical box)


Mine was similar noise with a faint whine, not long afterwards the idler bearings shat themselfs.

check your exhaust isnt touching the body, this can make misleading noises.....
