Question about 2004 Dodge Caravan
The engine is producing a rattle, under load, only in the RPM range of 1500 - 2000. The noise is not a ticking, squealing or high pitched rub. It is as if ball bearings are rattling around or being shaken inside the motor. The noise mostly comes from behind the intake plenum.
The engine performs very well. Plenty of power, starts everytime and is getting 19-20 mpg around town. You can make the noise appear and disappear by going up a hill and feathering the gas to keep the van doing 2,000 RPM.
Any suggestions are greatly appreciated.
Have your egr valvle checked, if not operating properly it can cause engine 'pinging' which sounds like what u are describing. Let me know how it goes. countrycurt0
