I just had my engine rebuilt and found out that it suffered from alittle thing called crank walk, which was caused by one of the thrust bearing wearing down and coming off. I have reason to suspect that the after market clutch might have something to do with it, do to the greater amount of clamping force that it's putting on the crank as it engages and disengages. I have heard rumors that this might me a common occurring problem on our engines and i'm wondering if there might me something that might be done about this. If you guys have any comments please add to the conversation.

A bearing can go bad from a simple piece of dirt or metal clogging the oil passage. After that, it basically falls apart. Doesnt mean that its a common problem.

Well, it's kinda hard now adays not to keep mashing the clutch stuck in traffic, but nevertheless. I agree with alot of the points you guys pointed out, I just wanted to post and hear what you guys had to say and have alittle piece of mind. But in my case I think lubrication played a major roll in it falling apart on me. I had just installed the clutch not more than 3 months ago, so I had that in the back of my mind.

I guess this is some good news and hoping it doesn't happen again since I just put about $5500 worth of work on the engine and hope not to have to take it apart any time soon if ever.

One motor that Blacktibs worked on (junkyard tib) had one of the spacers litterally "fall" out into the oil pan.
On another motor, one of the spacers was just eaten away down to a razors width.
You can check for it. If you remove the oil pan, then lever the crank from side to side along it's length, and then measure the amount of movement. Hyundai has published specs for what is allowable, and what indicates a problem. You can do it all without removing the motor...but it's alot easier if the motor is removed and on an engine stand.
