Crankwalk?!?....wtf!!!!
i understood that the evo 8 clutch system is different from the DSM 2g system. the evo 8 has a PULL type of clutch instead of the PUSH type of clutch which would rapidly increase the chances of crankwalk. the push style would obviously push towards the crank instead of pull away like the evo 8 to engage the clutch. anyone?? i had this discussion on socalevo.net before and talked with Jeremy Sosa a Mitsubishi Master Tech ( screen name is DR EVO i believe).
Can't a pull-type clutch cause crankwalk also since it places an axial load on the crank, but in the opposite direction? Hmmm.. maybe I should disable my clutch start switch just as a precaution.
i don't believe the crankwalk issues have anything to do with what internal parts your useing. the problem could come from push type configurations and high clamp load pressure plates though. also this was not a problem for the dsm's that had auto trans.

95-99 DSM's. It didn't become a problem when they switched over to the 7 bolt design, but when they started making the 4G63 in the US, which was in 95. The 1st Gen 7 bolt motors somply got different internals, (connecting rods, pistons, etc.). The 2nd Gens got the horrid bearings that were "matched" to suit the warped cranks.
Either way, it could be possible, since most cases of crankwalk showed up after people swapped in aftermarket clutches into their 2nd Gens which in turn would make the crankwalk process "speed up," if you will.

like others have posted i would seriously get a second opinion. this is almost unheard of for evos and think you have a diefferent problem. verify it yourself that your crank blade is in fact hitting your crank angle sensor. you can also measure the end play from the crank pulley to your cover. just pry a little on the pulley away from the engine a vise versa and measure with a dial caliper of some sort. good luck.
Wow, this will suck if there are other cases of crankwalk in our Evos. I knew of several people in 2nd Gen DSM's that had to deal with this problem. I had a 94 1st Gen Talon Tsi and had over 70,000 miles without any problems.
