I have a 2005 dodge raM 1500 4.7 207k with oil pressure issues when its hot and i come to a light the pressure drops and check gauges goes on i changed the oil pump timing chain tensioners and the sensor i just ordered another sensor to make sure what else could be doing this.... i am going to get mechanical gauge next but do the dash board displays go bad often?

 

Did you try replacing the sending unit?

 

yes i just did i am getting another one different brand to make sure.

 

It's really just a switch. It either shows pressure or no pressure. The gauge in the dash is no different than a dummy light in any other vehicle.

Have you checked the actual pressure with another gauge?

 

is there a way to jump out the pressure switch so when i put a mechanical one on permanently i dont have to listen to DING DING DING every time i come to the light i know there is pressure i just replaced the pump engine sounds fine i tried 2 new sensors still does it.

 

also what is normal oil pressure for this engine? when hot

 

Just piece together a brass T fitting and keep the original on there. I think the size is 1/4 or 1/2 npt

Edit - and while the pump moves fluid, pressure is generated by the tolerances between the internal components of the engine. 50 new oil pumps wont fix a worn out bearing.

 

depending on the current temps in your area, You may wanna switch to a different weight to see if the issues remains
