I should qualify a bit.....
over the years, I've stripped and rebuilt 12 Omega B V6 engines. In each case, the big ends were compromised to the extent that the bearing surface had completely worn away to expose the copper/brass substrate structure. I've yet to strip one where this hasn't happened.
None of the corresponding main bearings had been worn to that extent.
yes, of course the cause behind this is oil starvation and not the design of the engine
This is to be compared against the other 150 or so engines that I've rebuilt, which show a more normal bearing failure pattern across different types.
