Can hear it especially in 1st and a bit in 2nd gear. If i give it a bit of stick in first you can hear it aswell...almost sounds a bit like induction roar, but goes away once you change into the higher gears.

I can make it happen by slowly lifting the clutch pedal.

Engine still running fine so i've ruled out another engine rebuild LOL.

Anyone give me any ideas? Got me a bit stumped
