So, I am interested to hear others views on bearing inserts and especially machining the rear crank bearing journal/cap for a conventional rubber seal. For sure with a 216 you cannot do the seal unless you do the bearing inserts. But with inserts, the rear main cap is now a fixed dimension when torqued down (got rid of shims for babbit) so it can be machined to a tolerance that will accept a rubber seal.

I think I have this right...has anyone actually had this done?
