What exactly causes the sludge?? engine running to hot/cold? design flaw? ??

i read on dakota-durango.com awhile back that the oil pump in the 4.7 does not flow enough oil and that causes the sludge problem. If the pump could be increased it would help out alot.

Some guy was building up his 4.7 so not sure on his credentials
