Currently, from time to time, while breaking in the engine I am driving the car round trip 20-30 miles down the Tamiami Trail which is an open road for that stretch.. On a recent trip, the weather was cool, so the oil pressure was running 35 to 40 psi while the engine temperature was going up to 180 at 3000 rpm. At 4000 rpm the temperature climbed over 180 degrees and the oil pressure dropped below 30 psi. . I am considering replacing the oil pump and remember that there is a discussion about the quality of Moss pumps. Maybe I should buy the rebuild kit and change gears?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Oh by the way, on the last run all hell broke loose and had the car towed home.
