340 oil pressure? Help

Well now that you met RRR(who's not that bad by the way) , I agree .. your pressure is a bit low, but not going to kill your engine ... factory oil pressure spec is much lower than most folks are "comfortable" with ... to bad so sad on that one .... i personally think you should continue with your break in and see where the pressure settles when the engine is at operating temp .... plus you would not be seeing the pressures you currently have if those plugs were left out...
