If you find that your actual oil pressure is falling to near zero (the needle is supposed to move to the "normal" range once you have 5-7psi), then you may have a bad low pressure oil pump (LPOP) or a bad oil pressure regulator.
The pressure of the oil system which is indicated in the pressure gauge must be 6-9 Kg/cm2. This oil pressure is obtained by the help of the relief valve situated underneath the top or the oil pump. The temperature of the oil entering the engine (thermometer #11) must be more than 40oC and must not exceed 80oC The temperature of the oil leaving ...
Oct 16, 2019 · Pressure can also drop because the pump is no longer functioning as it’s supposed to. The work of the oil pump is critical since it facilitates the movement of the motor lubricant throughout the system. Think of it as your heart. If your heart stops beating, then it would be impossible for the blood to keep on flowing.
The pressure is just to low, goes to zero on the mechanical gauge also after warming up. Initially the gauge reads 75 PSI then falls to zero. Where do you start looking on one of these motors? Reading the manual I would have to pull the front differential to get the oil pan off of my 4 x 4 truck.
I also noticed that the turbo leaks oil through the bearings, although the excessive oil pressure may be exaggerating the problem. The engine blows a fine mist of oil while running. The oil can puddle in the turbo housing if the pump is left on while the engine is not running.
Nov 18, 2020 · This abnormal pressure occurs when other safety functions do not work due to failure. Figure 2. A steam safety valve in action. Image courtesy of Emerson. The safety valves’ design is according to the pressure that the valve can withstand, often called rated pressure.
Brought it to my mechanic & he hooked it up to check the pressure and everything was fine. He replaced the Oil pressure switch but that didnt help. Hes thinking it might be an electrical issue. Also, the oil gauge resets each start-up & the pressure drops after the engine has been running for about 10mins.
