all the pressure in the world don't mean the bearings will flow anymore. Pressure is the resistance of leakage. A drop in pressure will increase flow somewhere in the system. You have to find it. What kind of oiling system do you have? What in regards does the block have? Are you using needle bearing rockers? These are the things we need to know. Are the lifters bushed? Too much leakage to the number 4 main will cause rods 5 and 6 to suffer if it has a serious leak to the shafts. It takes away from the whole system. Let me know. I do other hydraulic work every day at my job. you could be sucking the pan dry Let me know, Steve
