Have to put rotor in distributor ever 1000 miles

Re-Check the wires. One may have come loose. For external coils, check there first. Next, make sure that the rotor is properly seated inside the cap on the Distributor.
Did you also replace any of the spark plugs?
It could also be completely unrelated. Haha. Check for fuel pump operations, and that you are getting fuel. Its either air/fuel/spark.
But definitely check the wires and rotor. Hopefully you put the securing screw back in.

Best of luck, mate.

how many miles on her it may be the timing chain

If it does have a cap there will be a rotor allso, But i highly dout that there is a distributor in that year of a van, That they use coil packs in it,

Distributors are a common failure item when it comes to Hondas wether it is the coil, the igniter. Replace the distributor assembly if you have already ruled out all other possibilities such as crank sensor, timing belt...

I DONT KNOW WHAT STATE YOU ARE IN BUT EMMISSION ARE ONLY FOR CARS 94 AND ABOVE IN MOST STATES. ROTOR IS SIMPLE, REMOVE TIRE BRAKE S PULL PIN FROM ROTOR TAKE OF NUT WASHERS ECT, PUT IN A LITTLE AXLE GREASE IN ROTOR IN STALL BACK SAME WAY, -- BUT ME I WOULDNT CHANGE ANYTHING

if it ran for 4 miles and it was okay ,it is something simple check all the small wires around distributor .if you removed your distributor make sure clamp nut not loose otherwise your timing might be out

Does not sound right to me. What does he say is wrong with distributor? There are not two of them. If he means crankshaft position sensor, several sensors can be tested by one hour of labor by a good mechanic. You can even test them yourself with a $20 volt/ohmmeter. I would check both the crank and cam sensors. If those tested good, I would check fuel pressure at the injector rail. Test procedures are available online at the link below.

The only way that oil would get into the distributor is if the o-ring at the base of the distributor is damaged. To check this, do the following.

Remove the distributor cap. You will see the distributor rotor inside. With a sharpie, make a mark on the outside of the distributor in relation to where the rotor is pointing. (This is important so that your truck is still in time when you reinstall the distributor)
Remove the bolt holding down the distributor. It is commonly a 1/2" or 13mm bolt. Pull the distributor. At the base, you will see an O-ring in a groove at the bottom of the shaft just above the drive gear. If you don't see this O-ring, or it is damaged, that is your problem with oil in the distributor.

When installing the distributor, make sure your mark on the distributor housing is in line with your rotor. Clean and reinstall your dist. cap.

Its just fouled some plugs again. Need an overhaul. If you just put a valve job on it it will just put more stress on the rings and will need it anyway. Not much you can do except change plugs all the time!
God Bless Greg

Are you sure you didn't damage the distributor connector? check it carefully, lock into the distributor for any pin problems there, or better yet buy a rebuilt distributor, I am sure the issue is there.
