I measured the lines they are 1/8" , seems if the filter is pre filled what oil goes in goes out . checked lines on original oil filter they are 1/8 also ....does the oil stay in head and oil system and not return to the pan ???? If I never lose oil pressure will my bearings be starved for oil ???? If 10 percent goes through filter then after 10 times of oil displacement would 100 percent be filtered ????
