Oil Pressure?

supraguy · 05-16-2010, 03:54 AM

Hi guys, I've had this ongoing problem with low oil pressure. I start up the car with 30ish, but when it warms up the gauge reads 0! I went out and bought a matco oil pressure tester. I have about 3-4 psi at idle (warm) Testing oil pressure is done at 3,000 rpm, which I have about 32psi. I should have 36-71. The car idles fine, no knocks but it kind of rattles around 2,500 rpm. I dont think it's a rod knock but I could be wrong. The car sounds just fine driving around town, you cant hear anything with the hood closed. What do you guys think?
