Hi all,
I want to preface this by saying that I am very neurotic when it comes to my vehicles and tend to stare at gauges/temperatures constantly and worry about what they are reading. I posted around a year ago about oil pressure gauge flutter at steady throttle and the forums said normal and Ford didn't find anything; I've been able to put that out of my mind, but with my incessant watching of the oil pressure gauge, I've noticed other weird things. When the oil is at least 200F, I notice a fluctuation in the gauge under light to moderate acceleration. Say I start accelerating a bit in 5th at about 75mph or so, the gauge will go up to about 100psi and then drop a bit to say 95psi, then bounce back to 100ish, back and forth. As RPMs rise, this is lessened to a degree. But I have noticed it doing this around 4k rpm in 5th with moderate throttle. It appears to be completely steady at WOT. Oil level is full, and this oil only has 1300 miles on it, but the same flutter is there on brand new oil as well. Car has 52500 miles on her.
Am I just seeing the pressure spring relief in the pump opening and closing until enough load/flow is created to hold it open? Should I stop staring at the gauge and just drive? I'm leaning towards thinking that it's just the relief spring and have been thinking that way since I first noticed it; but here we are......
Thanks!
