NOISY LIFTERS

2003 Dodge Caravan

Engine Mechanical problem
2003 Dodge Caravan 6 cyl Front Wheel Drive Automatic 72000 miles

At idle speed, motor rattles. I believe noisy lifters. When placed under a load, runs perfect, no noises.

Is there anything that can be done to stop this, other than having the lifters adjusted (flush motor, additives)? Is there any harm in letting it continue to rattle?

I just purchased the van, oil very dirty at that time. Oil filter dated two years ago, and van was being driven regularly. Could neglect have caused buildup, sticking lifters I have since changed the oil, still noisy. Also put in higher octane gas to make sure, no change.
