I have 0 oil pressure at idle, it isn't until 1200 rims I get normal oil oressure. I just changed my oil because of this issue, I figured clogged oil filter. This didn't fix the problem. The car runs drives and sounds fine, and there is no oil leaks, does anyone know the issue??

 

I wouldn't drive it until you figure this out. Could be oil pump going out. Do have enough oil in the engine? I know silly question.

 

To start with I assume that you have an actual oil pressure gauge. I have found that normal hot oil pressure on the Coyote engine is 25-28 psi at idle, 75-83 psi at 2,200 rpm and 100 psi + at 4,000 rpm on up. This is with 5w30 Mobil 1 full synthetic. While I don't have any direct personal experience with the 5.0 oil pump I do have experience with engine oil pumps in general. To the best of my knowledge all oil pumps have a pressure relief valve. If the valve sticks in the open position it can create just the situation you have described. The valve which is in the form of a piston moves back and forth in a cylinder within the pump body or at least it does in the pumps I am familiar with. A spring is used to push the valve closed and oil pressure forces it open. The amount of spring pressure is what determines oil pressure along with internal clearances in the engine. Over time the piston can form a ridge in the cylinder just as the piston rings do at the top of the engines cylinder bores. If for some reason the relief valve piston moves past the ridge the spring may not have enough pressure to force the piston [ valve ] back to the closed position thus oil pressure drops to zero or close to it until the rpms come up. The usually only happens on high mileage engines in cold temps with relatively thick oil. Good luck and please let us know what you find.
