I have a 2016 wrangler 4d willy 48k miles . A little bit ago I got a cylinder 2 missfire code P0302 DTC severity 2 of 3. Alongside that I am having the ticking sound on the driver side. I ordered rocker arms to replace and while taking everything apart and noticed oil in my intake manifold where my CAI connects. After finding I put this project on hold until I got more information, figured id hit the forum before having a tech look at it. It does not smoke, idles fine, pressure is fine. Before taking apart I reset the code drove without setting code off for 3 days then came on again now I am letting it sit until I figure everything out. So I am curious of your opinions and if its possible the rocker arm can cause all of this. Thanks!

I know a dirty air filter can cause oil to be sucked through the PCV Valve. Also, a bad PCV Valve will allow oil to show up in the intake manifold with a clean air filter.
