so close but still problems, oil pressure Options

[pxcr440]

ok so i have car up and runnign for a couple weeks now but as soon as i the car warms up the oil pressure drops to like 15-20 all the time , when i start it up its at like 50 now it really wont go above 55 psi , another thing now my car makes this wining noise that come from the passenger side it get louder with rpms , the wird thing is aobut these things the car runns perfectly expept for the low idle that is my fault, no problem just turn it up ,
what could be the probles with the car is it the gauge or what

sounds normal to me.

im not sure what the recomended oil pressure for a 5sfe is, but on my 3sgte i get around 50 at cold start up. then when it warms up, it idles around 10-12.5psi and on the expressway, stays around 50psi. according to the toyota BGB, this is all within spec.

there are a lot of factors that are involved in oil pressure. synthetic oil will read lower pressure, so will hot weather, then there is the oil weight and brand that you are using.

the wining noise, sounds like a loose/old belt to me.
