Great info!
Guess my 135i might be coming quicker than I thought...

You might want to try to hit some junk yards up for a used engine. It is possible one of them might not realize what they have and give you a good deal for it. After all the reading I have done on lightweight crank pulleys that was probally the cause of your problems. I had one and removed it from my car to reinstall the oem pulley. I am going boost soon and bought one of these http://www.atiperformanceproducts.co.../damtoyota.htm
call it overkill if you want to but I would rather have piece of mind. I am working on getting a complete engine build and this pulley will be used on that as well.

Well, thanks again for some of the replies, emails, etc, I am assuming that at this point there isn't much I can do to try and say the dealership was at fault. Both of the thrust bearings were in the oil pan, only one of them was actually pictured, if what MrC says are the possible reasons, then the 2nd one I dont think is it because it's the correct bearing. The 1st senario however could be it, but at this point since it's already apart, there is obviously no way of proving anything, especially with the 109,000 miles+ and the crank pully.
I'm going to keep dealing with the one gentlemen I'm working with for having a 1-piece upper thrust bearing made, there is still enough lip to seat the bearing into place and from what I'm being told from those actually having hands on, it will make my engine as good as new because the 1-piece basically eliminates the issue all together.
More to follow once I get word back about the 1-piece, or there will be another built motor journey.

I sent you a reply on scikotis as well. Sorry to doubt you.. but if you knew the person I am talking about, you would understand :D
I would certainly stay away from the pulley on the new build. Someone asked ATI to build pullies for the tC a long while back. Their reply was that if they built one, it would be for modded engines and would have MORE damper, not less
In other words, they dont support using a non-dampened pulley on an engine designed to use a dampened pulley.
There was another guy having issues with his front seal leaking after installing one over on ystc. Pulley was properly installed, no issues with contact, etc. For the record, I had a cavalier with crankwalk issues.. it went through 2 front seals in 1 month. Dont get me into that one... it had zero endplay, crank seemed to walk the "wrong" direction.. enough to grind the pulley into the timing cover .. so a good amount. Chalked it up finally to block flex and trashed the whole thing My dad (40 year mechanic) and a very good machine shop could not figure it out, so that was about the best we could do with it. But.. to digress... ...
The largest problem with them on supras was crank walk as well.
So, maybe not the cause, could certainly be it, but I wouldnt risk it again.
I wouldnt worry about it happening again otherwise, since this is obviously a fairly rare issue on this motor.

It's all about the "One Love" we have for these cars, if folks cannot come here to post and get answers, how the hell are we supposed to grow as a community?
Always a rare issue with my motor haha, so I'm just going to take what I've learned here and hopefully figure out what not to do next time.. if I had to take a stab, I'd say with the crappy service and issues I had with the Toyota of SOMD experience in my Gotti Saga thread, I wouldn't doubt that some jackass installed the thrust bearing backwards... I know the 23mm crank bearing was used, that's not an option...
Pully, as you already said, could go on for days about it... but hell, almost 75,000 miles with it on and it took that long, I'd still say it was worth the fun while it lasted.
For the record, that picture is funny... just haven't been in the best of moods when my car's been down for some time now.
Aight, I've exhausted what I need from this thread, ya'll hold it down and I'll see some of you on Scikotics I'm sure in the future!
Gotti out!

You might wanna check out the way the engine is engineered before you open your mouth. #2 this would be the first toyota in the History of yota to ever have this problem... you might wanna take it to a toyota specialest instead of a DSM specialest
Secondly, crankwalk will happen when the thrust bearing goes, reference the first picture posted. Yes, it's also a result of an oil problem, refer to my other historical thread or "saga" and you'll see this isn't a new issue at all... PAL!
Third, my mouth stays open because I contribute to this community kid... again, let's keep your SL e-ego tame... Sport!
Yes, 1st Toyota is absoutely correct, and I did research to come to the conclusion this is a common issue in DSM's and not in 2AZFE's...
Now, with that being said...
#2 you clearly spun a baring
#3 how many DSM's have you owned and what do you know about them.... if you have did you own a 1st gen or a second gen... thats just to test your knowlage.... and if im the "kid" than damn old man I must be smarter than you
