Stop Crank Before It Happens

Is there any way to stop crankwalk in 2g dsm's before it starts happing? New bushings, stoker kit? or is the only way to prevent it to switch to a 6 bolt. but what happens to all the engine mods i've already invested in?

Unless you've upgraded your internals, every mod you have works with a 6 bolt blocks. Externaly the blocks are effectively identical. There is no way to prevent crankwalk, but we do know that any oil system problem will likely cause it. That means always have fresh clean oil, dont let the filter back off, coolant in the oil, etc.
