I believe this just started happening, though it's possible I simply hadn't noticed it before...

Oil pressure is sitting around 25 at idle and jumps to 60 as soon as I accelerate. It does not drop back as the rpms drop though. It drops once I've let off the gas and the speed has dropped to 25 or so. Then the oil pressure slowly drops back to 20-25.

I have an erratic Speedo, could this just be a cluster issue? I haven't noticed any difference in how the truck drives. Anything in particular I should watch out for?

Mines 20 at idle, 60 while giving it has, and 40 cruising. Has been since I got the truck. It's normal

If it's not knocking, tapping, or smoking I say you're good

Engine purrs nicely.

I noticed today, during my short drive, that the pressure was sitting at 60, which I believe is where it usually sits, for the first couple minutes of my drive, but then started to move around again after those first few minutes. The engine wasn't warm yet, but I suppose it was warming up a bit.
