I was driving and all of the sudden the van died and the oil light came on, and now it wont start.

Sounds like you damaged the engine by running it without oil. Sorry but you probably need a new engine.

If oil level is correct, it could be a bad sender.

The OIL LIGHT will come on when the Car Dies. Crankshaft Sensor, Fuel Issue. Is there Spark? Will it start if you spray Starting Fluid into the Intake while it is cranking?

Trying to determine if the Fuel Pump failed or another reason... Report back with the above information

Check the fuel pressure

The oil you described is called blow back, which means the oil leaking is blowing back on the bottom side of van,, Those vans are known for computor problems, Which means they need re flashed once they start like dash lites wont come on or cooling fan wont come on and van over heats,or wipers ,radio wont come on than all of a sudden they come on,,I just got rid of a nice looking 98 had same problems.Also the main bearing on yours is leaking oil, I wont buy that van.You do what you want but Dodge,cryseler,are cheap made vehecles, I just answered a 2000 van that had the reflash problem here on fixya.So look around.

check the oil and see if it looks milky could be blown head gasket. see if it low on water

I'd feel best if you can find a reputable mec and have it looked at. There are a mess of things that can make loud noise. You could have anything from a bad berring to a blown engine. When your'e on the road remember go to someone who is reccomended or a national chain or dealer..

your alternator is not charging,have it checked out

SOUNDS LIKE YOU NEED TO REPLACE THE THROTTLE POSITION SENSER.GET THE CODES READ TO CONFIRM. AS FOR THE VALVE NOISE,YOU MAY HAVE A STICKY LIFTER,TRY SWITCHING TO A THINNER OIL OR MAYBE TRY SYNTHETIC.

most of times stalling problems are related with crankshaft sensors have your crank sensor replace and see if this will take care of your problem
