Hello All, after such good recommendations for my last problem, I had to try this again. After reading another post about oil pressure, I think I might have a problem. My oil pressure gauge always reads 40Psi and the only time it moves from that is during start up. I'm now thinking the only reason it moves is because of the electrical break in current when starting. What should the oil pressure be? Should it fluctuate (my 454 did)? This sounds like a stuck sending unit, I disconnected but nothing changed. Are there two of them? Where are they located? I won't have time to work on it for a few days. Will a car sending unit work as a replacement? Thanks again to All for the help, it's appreciated!
James,

One would think that it would fluctuate with rpm changes and whether cold or hot.
Can you try a different gauge or an oil pressure tester?

ground the sender lead, the guage should peg. if it does the gauge is good.
