One day they'll get it right. To get around these issues, the rod bearings will have to be replaced as preventative maintenance. Some vendor will create a baffled oil pan that will help with the pickup issue, or you can install a dry sump solution, both of which will only be needed for the hardcore racing situations. In that case, I think an S55 would be better to track.

I believe they have already got around it with the B58. Toyota had part in the design, testing and reliability development in that engine. It should is much better than all of its inline 6 predecessors.
