Interactive Even contested intellegence) is not uncommon on forums. We all need to be civil, but free discussion is good.
The pressure in your lube system should be 10psi at Idle hot. If it is above that, and not knocking, things should be OK. I would use 15-40 Rotella, or RPM Delo oil in the tractor to see if it makes a difference. The cover plate on the oil pumps have been shown to be a problem, and can be sanded flat on a plate glass surface with 200 silicon carbide paper followed by 400 grit to polish. Use non directional even pressure to flatten the cover. The end clearance on the pump should be between .0008 and .001 The gaskets are very thin, and used as a shim to adjust this clearance. If I took off the pan and found no issue with the oil pump, then I would plastigauge the mains and rods (.001-.003 are fine More is bad)
Try the oil thing first, then the pump, then the bearings in that order. JimN
