I guess thats a good observation. Looking at it from that angle it shouldnt be a concern unless cummins use a different type of bearing which is not the case.

I have heard a few different people tell me that cummins lowered pressure due to washed out bearings in the past on older model engines. Each engine maker has their own oil flow designs, and it is likely comparing one brand of engine to another would be a bit short sighted, even if they do use similar parts. Who knows for sure.
