Oil Pressure gauge drops and rises.

Oil Pressure gauge drops and rises.
So when i start my truck the oil pressure gauge is normal. When i start to drive it's fine till i am at a complete stop,it drops down all the way. When i hit the gas to go it goes back up not to the middle where it normally is but enough to keep the "Check Gauges" light off. Then when i stop again it goes all the way down and the light goes on. Seems like when the truck is elevated with the hood higher it doesnt go on. I'm thinking it's the oil pressure switch?? What do you guys think? I got the oil changed the day after this happened and the guy did not see anything leaking at all. Any idea's would really help me out. The truck still drives like it always did.

I have the same issue. It could be the oil pressure switch, but there are alot of other factors to. For me I think its a PCV valve and a vacume leak, still working on it. Anyways its easy to install a new switch. Its right on the top of the engine with a little electrical socket attached to it. Just remove the socket and take a wrench or some vice grips to it. I didnt have a wrench that big so I used vice grips and got it in there nice and tight. Its really easy, probably take you less than 5 minutes. If that doesnt work get a mechanical oil gauge and see if the problem is electrical or not. If its not electrical then I would worry a little bit.

Ok so i went with buying the Oil Pressure Switch. Changed that and everything is fine now. But what a pain in the *** to change. It's located right on top of the oil filter,and there is not a lot of room to get it off. The harness is a little tricky as well, you must slide the red clip to the side and press the plastic clip down and pull it off. I didnt have a long enough deep socket to take it off so that made it extra hard. I was able to get it off with a pair of needle nose pliers.I also took the oil filter off to give me more access to the switch. Took me about a half hour. If i had to do it again it would have only taken about 15 minutes.

On the 5.9L and 5.2L it is located just like 2 inch's to the passenger side of the T-stat (upper radiator hose into the engine). The T-stat is in the very front and center of the intake manifold (like a Ford 360 block --->Widow).
Replace the PCV valve as that can drop oil pressure.
