Best bet is to make sure the cam isn't frozen then replace the chain, there is a very good likelyhood it was just a defective chain if it failed that soon. The 4.0L I6 is a non-interference engine so bent valves shouldn't be an issue.
Even if you don't have shavings in the oil I'd probably do a couple "short" (only a few hundred miles) oil/filter changes to make sure to clean out any carp that may have come from the failed chain.

^This, as long as it was just large chunks of metal from the chain/gears it should have never made it past the pick-up screen on the oil pump. If the oil is full of fine shavings then you may have issues (though if it wasn't run for long with the shavings you may still be ok, the oil filter will pick these up but it will quickly clog up and once it goes into bypass mode that's when damage will occur).

That's her!
kgm,
"it's all good, I believe the US industries can send chicken to China now to have it "processed" and send it back and still label it US borne."
I've lived and worked around chicken/turkey houses and the processing plant for almost 40yrs in this country. I don't eat it.
