possible crank walk?

hey guys ive got a problem with my evo.. 2 me it feels like theres something wrong with the clutch.. first thing is i hear a knocking noise when i engage the clutch it goes away.. when i rev the car up at about 2500rpm it vibrates so hard that it feels like its giving u a massage lol. second thing is that when i engage the clutch the whole motor pulls down.. its been like this for 2 months now ive been driving it everyday.. drives and boosts fine.. another weird thing is when i rev it past 6000rpm while clutch engaged on 1st gear the car starts 2 move! any ideas please?

by the way car is a evo 4 with evo 7 motor and tranny

seems to me you clutch is slipping, and the bearing could possibly be busted also... try going WOT in fifth gear and see if the revs jump, then you know your clutch is bad.

I never heard of crank walk producing a big vibration. I've heard of clutches coming apart and then being out of balance.

What about when I'm engaging the clutch and the whole motor moves?

The crank walk occurs when you turn left and feel the clutch pedal fail...
