Oil Pressure Delay
I have recently noticed that when I start my truck, it takes about 5 seconds or so of running until the oil pressure rises. Other than that, it runs fine. Is this normal, or a sign of a problem that is about to manifest? Any help would be greatly appreciated.

My truck does the same thing, it all has to do with the fact that there is no checks in the oil system to keep it from draining back... Think of all the things you have to fill again; oil lines to turbo, turbo, oil galley in the block, etc. Now factor in any cold temperatures and there you have your problem. I put some silicone heater pads on my oil pan to warm up the oil so that it only takes about 2 seconds in the winter (much like the summer) otherwise it takes quite awhile at 0* and below for oil pressure to come up... Gotta love that good ol' Wisconsin weather

My understanding is that the delay is electronic when in fact your pressure comes up pretty fast. Easy way to prove this is to shut your engine down then restart it before there is time for drainback. It will still take a few seconds for the gauge to respond.

Mine does the same when the temperature hovers around zero. A magnetic heater stuck on the oil pan might make a difference. Infidel is correct, even during summer after a short shut down it takes a few seconds for the oil pressure to come up on restart.

It does take a while for oil to reach the rockers. I can hear when it reaches the top and the gauge is always a second or more behind.
That's one of the easons that Cummins changed the ISB & C oiling systems to spike at 130 psi. Get lube u faster especially on the C series with roller bearing rockers.
