FINAL FIX- found #2 cylinder intake valve rocker arm roller damaged. Up and down movement on roller axle pin.Only one of the 2 intake rocker arms had play but I changed both intake rockers for #2 cylinder just in case. Bought 2 new roller rockers from local dodge dealership ($20/unit CAD). . Removed,checked and reinstalled all other rollers of rocker arms of both intake and exhaust cams on this head, no play found. Intake seals replaced during reassembly. NOTE- previously found oil wetted intake runners were much cleaner/drier since I had replaced the original ( 126,000kms) PCV valve. I strongly recommend changing PCV valve as per maintenance schedule of 96,000kms. On start up engine vibration/ rough idle was non existant. Cleared engine code, went for a drive , all good. Hope all this has helped as all previous posts ffrom other members have helped me diagnos and fix this issue. I have filed my VIN with class action law suit in Canada against FCA ( Fiat Chrysler Canada) for this manufacturing failure. Feel free to ask any questions about this issue and I will try to help.

UPdate- I have swapped #2 and #1 coil packs and also spark plugs to see if code changes to #1 cylinder. While having the inatke manifold out and laying on workbench there was a significant amount of engine oil coming out of the #1 and #2 cylinder runners. Did niot expect to see this. Cleaned out manifold as much as possible. PCV valve replaced as possible reason for excessive oil in manifold.Perfromed leak down test of #2 cylinder at 80 PSI. #2 cylinder held 80 psi , no difference in pressure values. So no head damage on valves or piston rings. Reasembled, erased code P0302, engine started and idled for  2 minutes, rough idle but no engine check light, drove for 20 miles at highway speeds no code. Next day on cold start idled for 1 minute and engine light came on, checked code, again P0302. Will be changing #2 cylinder rocker arms, any rockers with loose lifter rollers. Will update when completed.
