Question about crankwalk?

I have spent the good part of 2 days reading and trying to understand crankwalk in the later (95-98) 4g63 motors. I am looking at purchasing a 96 talon and doing some work to it. The only thing i am worried about is crankwalk. My main question is do they sell a crankshaft or a thrust bearing that can eliminate crank walk?, and if they do what is the website. My second question being is there any other way to eliminate crank walk WITHOUT swapping in a 6 bolt. I know you can do a 6 bolt swap but i would like to keep the original (definitaley rebuilt though) 7 bolt 2g motor in it. Thanks for any help.

As things stand now, there is no 100% cure for crankwalk. There are many theorys to what actually causes it and a few have believed to prolong the effects of crankwalk. One theory is that the bearings do not allow the proper amount of oil needed for proper lubrication. Another major theory is the whole thrust bearing theory. Some motors crankwalk and others don't. They say that if the car makes it past the 50k mile mark then your usually safe. BUT, mine was at 105k when it crankwalked. Mind you though that I added a heavier clutch at about 90k miles. That gave it about 15k miles of extra strain that it obviously didn't like. Which puts it at about the 10-30k mile mark to when most of them actually crankwalked... If all that makes sense. So really your taking a gamble on getting a 2g... Are ya feelin lucky? lol :wink:

mine walked at 75k. I fixed it the cheap way and just threw in new bearings and it runs like a champ

Just do the 6 bolt swap. You can put all sorts of money into a new crank and getting shit machined for the "CW cure" but what if that all doesnt work and you walk it in a few thousand miles? The money would be way better spent just getting a 6 bolt.

I'm with Dustin. And why would you want to spend the money to re-build a motor that you don't know for sure if it'll stay together instead of swapping in one that won't break? I'm not a big gambler when it comes to motors, and if you think the car will be worth more with the original motor in it, you're wrong. These aren't old muscle cars, casting numbers and what not don't matter.
