I do agree with Gene. These tractors in almost all case will loose most oil pressure after being worked and the oil warms and thins. If it runs 7 lbs or more it will be fine. If the rod bearings were in very bad shape it would be knocking and or rattling. When tractor is warm it is very normal for pressure to drop to very low on the gauge when idling. Lots of these gauges simply are not accurate to start with, so I would get a good test gauge and see what it says before tearing it down and spending 1500 dollars that may not need to be spent. I have farmed with these things for nearly 40 years and have never seen one that didn't drop oil pressure significantly. I have sevaral that I use on a very regular basis and all of them loose quite a bit of pressure after warming. Even on a fresh overhaul. You can also get a feel of how well it is oiling by getting it warm and removing the valve cover to see how much oil is getting to the top of engine at an idle. Like John, I have never heard of rod caps stretching either.
