Hi Old Jack
There are a few trains of thought
1, the oil calcium level in Jap is +3000ppm Mmmmm
2, harmonics of the turbos affecting oil flow or other Zzzzzz
3, bearing material was faulty-yeah right
4, oil pressure too low for load/and or rev range. (this one is
mine)
I used to do a bit of rallying in the datto, and the rule of thumb was 10psi per 1000 rpm, so if you have 35 hot, and you can rev past 4000 with a long throw crank, the oil in the crank can be centrifically thrown to the bigends faster than the oil can be pumped into the mains, and the bigends end up loosing flow.
Explains only if the motor is reved that fast, non genuine filters are used, thinner oil or lower quality is used,
In the end who knows exactly why?? One thing is for sure, if the ACL does thesame as the Toyota, it wasnt a faulty set of brgs. Do them every 100k
