Bob I am certainly no hacker and was not "going for the put down" as you referred to it. I simply disagree as to the mportance of having the oiling system pressurized. Without pressure, the thin film of oil can get squeezed out from between the two surfaces, then your bearing will stick to the crankshaft and get spun. Comparing the lubrication requirements of meshing gears to that of your rod and main bearings is misleading. The high loads subjected to a rod bearing require oil pressure to live very long. What I was interested in sharing with the people here is that if your oil gauge shows pressure (better than 40 psi lets say) than putting on a high volume pump will not help anything, and will increase wear on the dist gear and stretch on the timing chain, without improving oiling at all.
