Dieselfixer Posted November 16, 2012 Share Posted November 16, 2012 Hi All Does anyone know what the normal oil pressure is for an E7-300 engine? I have 1 here that is only showing 15lbs at cold start. I think it is way too low. Quote Link to comment Share on other sites More sharing options...

oilburner Posted November 20, 2012 Share Posted November 20, 2012 I don't know for sure, but cold mine has about 70 lbs and at 190 it has 20 lbs at 600 rpm!! Quote Link to comment Share on other sites More sharing options...
masterwelder Posted November 20, 2012 Share Posted November 20, 2012 Did you notice what it is when hot? Quote Link to comment Share on other sites More sharing options...
e9500v8 Posted November 20, 2012 Share Posted November 20, 2012 I got a 97 e7 350 that is the same way has 15 lbs when hot idling and not over 50 lbs high idle hot. So at 100,000 miles I put new oil pump in and it made no difference now it has 450,000 on it and is yet to have a set of bearings. So it must be ok.
