s2on20,

Had to change the crown & pinion which cost the 1500 from Honda. The pinion itself had a massive chunk torn out of it which caused the loud "whine & teeth grinding" noise which you hear.

My problem now is that its just making a clunking noise as I launch from neutral to first and even changing between gears, as well as swinging the clutch in and out, I hear a clicking noise coming from the diff. The car is still at the mechanics, I will let you know what happens.

Cheers
