Some time back I had a mechanic replace the sump on my 6.9 which had been cracked. Ever since that job, I have a decrease in oil presure when I make a left hand turn. Pressure remains constant when the car turns to the right. I am theorizing that centrufigal force is letting oil move towards the resevoir and this may be happening in that those numerous fittings at the sump end of the two larger hoses may have been incorrectly installed. What purpose do those fittings serve, are they check valves designed to prevent backflow?
