Is oil pressure normally this high? I took this after it actually dropped a little. It was halfway between the last tick and 120 (my guess is around 100 psi?). This was with outside temperature around 60-65, so it'* not from cold weather.
After about ten minutes it drops to around 40 psi. Then after driving for a while when I'm idling the needle bounces a little, my guess is the bouncing is from the intake leak which is only apparent on a hot engine.
Anyway, do I need to check my oil pressure relief valve? Is the fact that it is holding this high of pressure a good sign that the engine bearings are in decent shape? The gauge was replaced a couple years ago, so I would expect the gauge is reading accurately.
