I have recently been trying to detirmine the overall health of my motor, which was broought on by a faulse oil pressure warning...oil pressure and temp gauges were installed and the show the bottom to be in good health, and the comp readings were ranging from 155-165 which seems low but at least its fairly even the motor has around 200k on it ( the odom) broke at 111k so the timing components are going to happen , but all else looks good.
