What do you need to look for when guying a dsm?

crankwalk is when the crank moves side to side in the motor, very commen 2 2nd gens, how to check? ehh you almost have to grab the crank and push it on on the timing belt side, then watch it while somebody pushes in the clutch and see if it moves

i am guessing it walks the crank because of poor thrust washers?
i am no dsm guy but i knew a kid who’s clutch wasent working because his shit was walking so bad
