A lean condition is not going to lead to a thrust bearing failure. That is engine knowledge, regardless of brand. Do you even know what crank walk is? Better yet, do you realize that any engine can do it? Some have shit main/bearing/cap designs that make it waaaay more common (DSM).
A lean condition can melt a piston, break ringlands, or toast and exhaust valve. It is not going to cause a lack of lubrication on your thrust bearing which causes the crank to walk (shaft endplay). Get off DSM tuners and go learn some stuff on a real tech site. I swear the guys on there think low windshield washer fluid and overinflated tires cause crank walk... It's not that complicated.
ok there you go as ur the smart one :
What is Crankwalk?
Ok, I will be using correct spelling since I seriously want everyone that reads this to understand as best as possible.
So now we know what a DSM is, but what is crankwalk? Crankwalk, or "the walking crankshaft", happens when the crankshaft starts moving around its housing. This causes the crankshaft to, at some point or another, wear into the thrust bearing heavily. This will cause the crank to eventually move a plate that will smash into the crank angle sensor, break it, and shut the car down.
That's why you have stages or upg on these know problems. Any kind of car turboed or not can do crank walk.
More fun is that most of the cars can't keep up with dsm's.
