I started the initial discussion thread over on m3cutters and after a private email conversation with paulgros, I found myself hanging on his every word. His engineering and specifically bearing knowledge is almost encyclopedic.

The key point is that the numbers that started this thread are definitely the correct ones for con rod play and con rod play is very much not the same as clearance.

It seems that a lot of people have been taken in by an incorrect assumption.

The oem nominal clearance is certainly bigger than is being touted here. Main reason for UK skepticism is the disproportionate number of failures you have had compared with us. It suggests there’s something else going on, other than just slightly lower than normal rod bearing clearance.
