right side engine knocking on 1998 Dodge Grand Caravan

Started hearing a knocking sound on my van about a week ago. It would only do it when it was started after sitting. My fiance checked to see if it was the flywheel hitting off the starter, which it wasn't. It has gotten worse. We have been told that it is either a lifter or a piston. Its not a constant knock, it is intermittent. Any ideas?

I would check the oil pressure, you may have a bad seal in the oil supply system that is causing intermittent low oil pressure.
