4.7 oil pressure acting up
just bought a 2000 dakota 4.7 about a month ago and so far i love it, when i bought it the oil pressure was high but still well within usable range, while driving it sometimes dropped below half but still well within usable range but today i was at a stoplight and seen it was down and as i sped up after it turned green the oil jumped back up to over normal.(which is where it spends most of its time) then i realised as the rpms dropped so did the oil pressure gage till it hit its usual low spot and again after accelerating it jumped back up. should i be concerned? any ideas on what it might be? this is the first ive noticed of it so ill see if it does it again tomorrow

I changed my oil a few weeks ago in my Dakota and I noticed afterwards that my oil pressure gauge was been dancing between the mid-mark and almost 75% mark. I was a little concerned at first but it soon stabilized.
I agree with 00DakDan. If the oil pressure gets excessively low often, I'd would keep a close eye on it or have it looked at.

yeah its still doin it today, seemed to idle a little lower then normal too. anyway im swapping out the oil again within the nest 800 km's the old guy who owned it before me couldnt remember the last time he changed it and when i did it the first time it was pretty black, might as well get rid of as much of that oil as possible. thanks again tho

BINGO! We have a winner! Its impossible to diagnose this issue without first checking the engines OP with a wet gauge. If when the pressure is low and your not hearing any type of taping or knocking noises it should hopefully be the OPS unit. I've seen more than one OPS unit get a slug of sludge or get plugged that will cause this issue.
