HOPEFULLY SOMEONE CAN HELP ME IVE RECENTLY FINISHED A 10 MONTH COMPLETE REBUILD ON MY 90 TO WHICH I FITTED A 3.5 V8 OUT OF A RANGE ROVER . WHEN I STARTED AND DROVE IT FOR THE FIRST TIME I GOT A NASTY LOUD NOISE AND MAJOR VIBRATION WHEN PULLING AWAY . THIS ONLY WENT AWAY WHEN I STOPPED AND RELEASED THE CLUTCH PEDAL . I USED A NEW CLUTCH KIT ON A SECOND HAND FLYWHEEL . THE ENGINE WAS ORIGINALLY AN AUTO IF THIS HELPS
