Why does the oil pressure drop in a 2.9 liter when it is up to operating temperature?
The oil pump supplies a volume of oil to the bearings where it is squeezed past to create oil pressure. With that said, the first thing I would do is to install a mechanical oil pressure gauge in place of the sending unit. Crank to engine and let it reach operating temperature and get readings along the way. If it holds above 10 pounds at idle then replace the pressure switch. Next I would change oil and filter as the filter has a built in relief valve. Then the next step would be to drop the oil pan and see if the strainer is partially stopped up. If not then look at a rod and main bearing for wear. If they are worn then rebuild the engine as you still have cam bearing you can check.

What causes oil pressure drop when engine has heated up during drive?
The oil gets thinner. It is normal for the oil pressure to drop after the engine has reached full operating temperature. If you have from 30-40 psi pressure when the engine is hot then that is normal.
What is a sign that the weather may changing for the worse?
A sudden drop in the temperature
What can happen if you had a sudden drop on boiler steam pressure without a corresponding drop in boiler water temperature?
BOILER EXPLOSION- Caused by a sudden drop in pressure (failure on the steam side) without acorresponding drop in temperature.
Is temperature related to pressure air?
Temperature is related to air pressure because the air pressure can determine the movement of wind. If cool winds move from areas of high pressure to low pressure zones, the temperature in that place will drop.
What causes the drop of a wall cloud?
A wall cloud marks an area of low pressure within a mesocyclone. The pressure drop causes a temperature drop, which in turn causes water vapr to condense.
What causes oil pressure to drop when idling on 98 suburban?
The oil is hot and the rpm's are low. When you first start up the internal rotating parts are colder and tighter then at operating temp which will drive the oil pressure up, as the engine gets to operating temp the gaps around the internal rotating parts change due to temperature, causing oil pressure to drop at an idle. Most people never notice this due to having warning lights instead of gauges.
How does temperature affect the atmospheric pressure of a place?
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
Which of the folling is the most reasonable explanation for a drop in temperature of a gas?
A decrease in pressure, a decrease in volume, or a transfer of thermal energy to the surroundings can all result in a drop in temperature of a gas.
Which of the following is the most reasonable explanation for a drop in temperature of a gas?
The most reasonable explanation for a drop in temperature of a gas is a decrease in pressure. When pressure is reduced, the gas molecules have less kinetic energy, leading to a decrease in temperature.
When you are moving higher to sky why do we suppose to get cold?
Because there is less air pressure, due to the drop in air pressure the temperature drops as well.
Temperature and pressure fall in the late morning?
Temperature and pressure can drop in the late morning due to a decrease in solar heating and atmospheric instability. This can lead to cooler temperatures and lower pressure as the day progresses.
What would make the coolant reach operating temperature then drop and not reach temperature again?
Always try simple first...thermostat is probably stuck open...cheap and easy replacement.
