Crunching sound after 2" lift?

[lifechariot]

Hi

I've just give my 3l TD 2nd Gen 1993 Auto a 2" lift so my 33" tyres would fit

But now there's a grating crunchy reving sound for a few seconds when I first turn the engine over

It only happens when the car has been sitting unused for several hours or overnight. It's coming from the back of the engine/gearbox area and it sounds really unhealthy.

Any ideas?

Thanks James
