I thought issues like this were already resolved, I figured this would be an informative post, not a summary of common knowledge. Any search of dsmtalk, dsmtuners, nabr private and public forums, any of the yahoo lists, any dsm related list in general, will list the 'monster clutch' theory of crankwalk. I know that besides a 'monster clutch' crankwalk has been linked to improper building techniques, improper block preperation (ranging from line hone, to clogged oil passages). The point is, fingerpointing on a public forum is useless. Crankwalk is as much of a 4g63 problem as spun bearings are to the 6g72. What saddens me is is the fact that it is always someone elses fault for a faulty rebuild. Fingerpointing gets people nowhere, lets turn this into a shared community thread of ways to 'prevent' crankwalk. Personally i've seen cases of nearly every tranny/motor/mods list out there crankwalking.
The things I personally believe that help fight against crankwalk are:
-line honing blocks w/torque plates still attached
-pinning caps
-proper assembly techniques (which I think is common knowledge, using plasti-gauge, etc).
-Making sure everything else 'attached' to the crank is in working order (from undampened pullys to improperly attached transmissions)
anyone have any other theories/ways to 'help prevent' crankwalk, please post them up.
Its unfortunate that this situation occured pubically once, and its unfortunate that it involves trusted members of the dsm community, but lets let by-gones be by-gones.
