The piston rings are failing. How long has it been since you changed your oil last? How many miles on your Caravan?

200k miles maybe 2 months since oil change

I'm leaning more towards a fuel delivery problem like stuck injector. When you start wearing rings you'll start blowing oil and getting wisps of blue smoke when you accelerate or mash the throttle. Easy way to check piston rings, use a compression tester on each cylinder

200,000 miles it could be the rings or what ytlas said.

If its blowing smoke it's time for a new engine. Try getting one out of a junkyard or just letting the van go and buy another one.

Would hate to have to let it go its in pretty good shape only ever had 1 code p1775 do u think that it could be causing these problems?

Some fuel systems have the fuel regulator in such a way as to leak and fill the cylinders during rest. The fuel accumulates in the oil. You would look at how yours is configured. if it was capable of leaking into the intake you would change the oil and replace the regulator, cease starting attempts. injectors that leak can do that on any fuel injected engine Cylinders get washed down by fuel and rings can lose their buildup.

Plugs can get fuel fouled , as an indicator, you can inspect them and expect to replace them. When testing fuel pressure, rest pressure would fall off faster than the rest pressure spec.

That is, if there was a part(s) leaking fuel when it is shut off. There have been recalls for some vehicles and many use the Bosch. They invented it, but some apps have had leaks leading to fires if neglected and allowed to keep driving and building up fuel in the crankcase. The ones that insert with an o'ring are the ones I mean.

Black smoke, rough run, plug fouling and or fuel in the crankcase are good symptoms for checking with your dealer for an update like a TSB or recall. They may steer you toward a part correction. diag steps, procedure updates, etc. If you had coverage, many warranties cover these items.
