1. That's not the impression given.
Also they do not even use the same molds because the block castings are different.

2. No specific bearing failure is labeled for the "suspected" zircon failures. Nothing has even been proven regarding the handful of 3L failures posted in the net. (hence my whole passing the buck comment and pointing out the 3L rebuild instructions are wrong when it comes to rod bolts)

Going by what information is available it would cause a main bearing failure not a rod bearing.


The 2.5L oil related failures are on either of the last 2 rod bearings.
#6 is the most prevalent and that makes sense since it's the first to lose oil when pressure drops.
