Shaun, it vibrates at all times but is mostly noticed @ 3200rpm's it is felt on the engine itself, gear shifter & clutch pedal.

Rick,

Is it possible that balance shaft is out of time.

I think Drew1 might have the right idea. If one, or both of the balance shafts are put on out of phase (VERY easy to do) it will vibrate worse than if it had no balance shafts at all.

hi Rick it sounds like one of the balance belts are out of time the only way to check is to remove the timing belt cover and see if the top balance pulley has a O showing thru one of the cutouts on the belt guide and the bottom pulley has the O showing thru one of the rectangular cutouts, the O means over..... early cars had 2 marks O and U marked on the pulley face they stopped putting the U on so if you dont see this then it is very possible that the bottom pulley will be out of time ... the other way to check this is to remove the balance belt and start the engine this will answer your question on the vibration.. if the pulleys are both indicating good then it is time to remove the balance covers and see if the weight has come loose , they are secured ith a set screw........Stan

I vote for balance shaft problem. It makes quite a vibration at double engine rpm if timing is off.

my 951 had the same vibration and we found that some dumb ass had the balance shaft 180 degrees off. Smooth as silk now.
