Can someone here please tell me if the 3.9 Magnum - circa 2002 - is a non-interference engine?

Do we feel lucky?I had a noise happening after an overhaul in which bad parts have been replaced on a 3.9. I have however figured out the reason for the noise.It is not that the cam timing is off.There is a loss of oil pressure. I let the engine run until warm. One leaky coolant hose manifests. Also one tappet not filling, when warm one piston beginning to knock and last but not least when warm after some minutes, oil pressure dropping to zero. So, I suspect there is a plug missing in the left bank main oil gallery at the rear of the engine...the last valve, valve rocker, push rod and tappet to fill in the path of the oil.I know there is no plug in it and I think one should be there. This is not scope related. Per chance that is what sets Logic off.
