RE: CRANKWALK....YES
Technically, crankwalk can happen to any motor with a crank..... Remember, that crankwalk is when the crank can move around the housing in an out of spec way...or should I say way out of spec. It does happen but it's called something else I'm sure, otherwise crankwalk wouldn't be so affectionately associated with manual 7 bolt 4g63s.

Movement of the crank out of stock specifications. All cranks have L to R movement, to some extent, but an excessive lateral crank movement has bad reprocussions, such as hitting/grinding/destroyi ng the crank sensor. A "walking" crank necessitates an engine rebuild.
Any car can crankwalk, but Mitsubishi Eclipses, Plymouth Lasers, and Eagle Talons with a 7-bolt motor are notorious for this problem. No recall was ever released as the problem was said to be isolated to a bad batch of cranks, which represented a fraction of the produced cars. Various theories of why crankwalk occurs and what years are most suseptible exist, but none are proven. General consenus is poor oil flow is one cause, and later model years seem to suffer less.
Contrary to popular opinion, any car can crankwalk; Manual, auto, import, domestic, turbo, manual, racecar, beater. All have walked, and all have a chance of walking.[/align]

However, it is possible for any engine to experience crankwalk if there is a problem with the crankshaft bearings. It has been reported that 'small rod' / 7-bolt flywheel motors (manufactured from later 1992 through 1994 on 1Gs) are more prone to crankwalk than 'big rod' / 6-bolt flywheel engines (manufactured from 1989 to early 1992). However, there can be no guarantees, since big block V8s and all other engines can also suffer from crankwalk.

Ooops, I should also add on to Josh's statement.
Crankwalk is more prone to happen to 2G "small rod" 4g63s than 420As. However, your 420a may already be walking, but without a lot of power to the crank, it's not going to be noticable nor will it (but still might) walk without putting excessive amount of power to it.

RE: CRANKWALK....YES
Like Silver said ANYTHING with a crank can crankwalk... its just that 7-bolts have a sick habit of doing it.
