Go nuts, honestly I wouldn't think much of it, even 6 bolts can have the issue and there are plenty of ppl running strong with 7 bolts.

Anymore, Id say about the only way you can get crankwalk is if you buy a early 7bolt motor(95-96/97) that has under 100k miles on it. The 97/98/98 7bolts didnt really have the crankwalk issue. And if your 7bolt can make it past the 100k mark, chances are, that block will never get crankwalk.

But to avoid it all together, just get a 1g 6bolt 4g63t block.

oh, i thought 100% of ppl with 7bolt 4g63t's had this issue.

No, in all reality only 2%, if that, experienced crankwalk, I mean 2% is still too much, but its not as bad as people think.

if you bypass the clutch ignition saftey switch,
and don't run anything more than a 2100 clutch.
you will more than likely NEVER have a problem with thrust bearing failure.

if you want a strong 7 bolt then delete the oil squirters. since they share oil from the same galley as the main bearings on the 7 bolt block, and the thrust bearing isn't directly fed with oil.... the oil squirters on a 7 bolt(asically check valves) get stuck open, and cause poor lubrication to the thrust bearing. couple that with a heavy clutch pushing back against the thrust bearing, and you have a recipe for failure.
