Oil Pressure Drop
 
2000 4.0 GC. My normal oil pressure hangs out around 65 but for the past few days every now and then when I stop at a red light or coast for a while, the oil pressure gauge will drop down to 55 or so. Once I start to accelerate, the pressure starts to rise until finally reaches the normal level.

Does this just happen or is there a reason?

I didnt look at specs before this response but 55 psi at warm idle is very healthy

Once warm my old 4.0 would run at those specs once warm, it did have over 200,000 miles on it though.

yeah even thirty is decent, again without looking at the specs, typicall chryslers specs are "above 5psi @ idle or above X @ 1500 rpm, the minimum specs are MINIMUM specs, when your reaching the minimum specs there are some problems, but 30psi is healthy.

Okay. I just wanted to check. I thought it was within the normal range but thought they sudden decrease and increase were a little odd.
