Every time the van is started there is a loud rattle right off the bat, idles smooth but rattles more loudly the higher the RPMs go. from what I have read it could be a loose heat shield, bad gas, or a bad Cad. converter. any suggestions?
Lifters lack oil/ lubrication. engine warms up oil flows better. Change oil now and go to 5W30 synthetic.

Fold dollar bills and wedge them into the gap of area rattling.
SOURCE: it rattles when in parked and in reverse
It may be just a exhaust hanger broke loose. Exhaust vibrating against the hanger. IF not then the inside of the converter may be damaged.

Yes, it could be, if bearing are bad in the water pump, but more then likely would also be leaking water (coolant), have your other pulleys also checked.

loose flexplate bolts would make noise all the time,wat u got sounds like a rattling catalytic convertor,meaning a worn out cat or cats. u can get under neath an hit on the exhaust pipe near the cats with engine off an hear the rattle ur talkin about. have u noticed a slight lack in power or performance ? another telltale sign of bad convertors. a local exhaust shop can raise car on lift an chek cats,inexpensive chek,expensive repair. good luck

Not without knowing exactly where the noise is coming from.
Noise seems to be directly under the gas peddle, can actually feel the rattle when pressing on the ges peddle.
