Like I say I always see the bearings go way before a rod or piston, seems to be the weak link.

You assume! Not to jump on you but ive had machinests "assume" many things. The most of which led to my displeasement and misfortune. Sadly enough you have to detail out everyting ahead of time in order to insure a proper build. Machinests arent psychics.
Yes the bearings are the weakest link...and for good reason. they are easy to replace and keep 20+ other things from going bad in the process. The key here is that bearings dont just fold under preasure especially under 10k miles. something causes them to do so (oil starvation, out of round surfaces, contaminates, fatigue, retardedness etc.
My bet is on the rods. Even simple installation will cause them to fail. All you need to do is pound it with a mallet, over/under torque the nutts, not check for fatigue and so on. I mean have you seen how small our rods are?
oil starvation...ive got 2 tt's with 180k and the other with 270k and no starvation problems. Ive got that little needle in my cluster that likes to hang out at the bottom as well
. Your new rebuild should not starve. Not unless you are doing something horribly wrong.
