I have a n-14 red top rated at 460 hp. I have 727k on it and the rods and such were done at 500k. My oil pressure usually stays around 10 pounds at idle and up to 30 when driving. Sometimes after running for a while it will drop off to sometimes 8 to 6 pounds aprox by reading the guage. I know cummins uses volume over oil pressure becuase my 3406b cat runs over 50 pounds at idle! anyways i belive the cam bearings are leaking ( to the left of the starter) would this cuase a drop in oil pressure? The truck has a pretty good oil leak looks more like a driptroit than a cummins.. Just wonderin how that would affect oil pressure. I am prevoisly a cat man so im new to these motors. Thank you
N14 oil pressure!
