Currently rebuilding a 3sgte and I've noticed that the main bearings I've been sent are slightly different to the ones I've pulled out.
The top end bearing is the same but the OEM bottom end bearing has a small oil galley that continues from the top end. The aftermarket ones I have bought don't seem to have this. Can anyone shed any light?Here is a link to a pic.
