usually round 40 lbs
40 psi with a warmed up engine sounds normal to me.
When dry ice is warmed at 1 atm of pressure, it goes back to its gaseous state or form.
they warmed up with a healthy diet!
Warm front
decreases i think
Warmed air sinks, creating a high-pressure area as it falls. ^ Not Quite Warmed air rises, creating a high-pressure system below
It is normal for the oil pressure to drop some when warmed up.
oil pressure normally will go up and down with rms for the most part. when the motor is cold there is more oil pressure as the oil and motor get warmed up the oil thins out and the pressure goes down.
The warming air would expand and the tyre pressure would go up.
It is normal for the oil pressure to drop when the engine is warmed up and at an idle.
MY Mercruiser 502 8.2L V8 between 133-155 pounds pressure dry, not warmed up & throttle at idle instead of wide open throttle. I was comparing the difference between the cylinders seeing if anything was obvious bad... Warmed up... Open throttle valve will give you a higher reading.
Defective radiator cap? Leak in system (Pressure test)? Head gasket?
