3.7 Dodge PCV system?

Hello, Everyone, hope all is well!
Ok, so my Jeep got Totalled in early Dec. LOVED my 4.0, at fault drivers insurance dragged their feet, had to get a truck at night...damn thing is Smoking! Supposed to be a 120,000 mile pull out replacement. NO pcv hooked up. Appears to have 2 nipples, on both heads, on the rear of both. Probed em with a wire... would that cause Smoking? Also, fit an EGR code... I CANNOT find a damn egr at the exhaust. Any ideas? I put new plugs in when I got it, not thinking to do a comp test.. damn lol. Lil sucker runs Great though. Except the smoke. Bought it off a young man... he dropped the price ( without me asking, after, as I was test driving solo, my Gal was telling him what happened. I offered him what his asking price was, even tried to hand him a hundred, so he could get his Mom a Christmas gift. He said all he wanted was his money back. 07 Dakota.
Thanks, Y'all
