Oil light comes on when l start van then goes off..oil pressure is at 4

It may just need an oil flush and filter change, yes.
It could also be the oil pressure relief valve that is sticking.It may even be the oil pressure transmitter switch that is faulty (not a big job to replace..).
However, try a filter and oil change first. Before the old oil is drained from the engine, try adding an oil sludge clearance additive. Link below will show you what it looks like.
oil flush Google Search

If the oil pressure relieve valve is sticking, the additive-flush may unstick it, before you fill with fresh oil. Use a quality oil - not a cheap brand

To put things into context, as oil breaks down with miles and age it becomes less 'pumpable' around the engine. If there was something wrong with your engine in the crankcase area you would probably begin to hear knocks and rumbles as the bearings break down. You haven't mentioned any noises.. I don't think you have much to worry about.

The first thing you do is flush the oil system using an additive and then refill with fresh oil and a filter. You can also add an 'oil booster' additive if you wish:

Oil pressure light 2007 Montana

Assuming you have enough oil (there is a separate low oil sensor) and you have replaced the filter (can go bad) a lot of times the oil pressure sensor is the problem, especially if it is intermittent and your engine is still sounding smooth.
The sensor located right above the oil filter - you need to access from under the vehicle after removing the starter motor (disconnect battery first). You will need a 27mm (1-1/16") deep socket to be able to unscrew the old and screw in the new sensor - do not tighten very much - 15 ft lbs I think.
The sensor is CA$38 at the dealership.

Light is on and pressure bell is ringing. oil is full- please tell me its not a huge problem

MOST(!) of the time, it is the pressure sensor that has failed. If the engine does not seem overly loud (it will, without any oil pressure), I would say this is your problem. If you aren't sure you can recognize the sensor (it will normally have a single wire and a hex fitting for removal), I suggest you buy a manual for your Montana and the pressure sensor at the same time. I like Haynes manuals and they can be found on line, at eBay or sometimes, even at a local library. If, however, your engine IS loud, it shouldn't be driven under its own power at all until the source of the failure is found.

What does a low oil pressure alarm mean

It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.

2001 Montana Low oil pressure message

It is possible,look at the oil pressure switch,and see if it is still plugged up good.Also,it might be leaking,if so,replace it.You might replace it any way to make sure the sending unit is reading correctly,If it is not a loose plug on the oil sending unit.It should be right next to the oil filter kinda long.
