Rollover aftermath? Oil in airbox/throttle body...

Hey folks, Some of you participated in my insurance/bodywork post after I flopped my truck on its passenger side. Thanks! Thats all taken care of.

Something else has come up,
While it was on its side it spilled some oil out under the headlight. After we got it righted back up (it was on its side 15 minutes, max) it started and ran fine (blew some white smoke for a minute as expected) but I noticed the airbox had oil all over it and inside. I cleaned it out best i could and replaced the filter. Now, several weeks of driving later I looked at the air filter and its got some oil on it again, on the bottom. I took the airbox off and the air hose to the throttle body and saw theres some burned oil residue in there, as well as some oily gunk in the hose that enters the air hose down from the throttle body. (PCV?) See photo. I cleaned all this out and will be checking again soon to see if it stayed clean or not.
I haven't driven it enough since the rollover to notice if its burning oil. But I will tell you that up to now, even with 300k+ on this engine it has never lost oil between 5000 mile oil change intervals.
What do you think? something I should be worried about? Anything I can do to keep this from happening? I expect folks will mention the PCV valve and tell me to check the spark plugs. Ill have time later this week for that.
Its a 02 3.4 4x4

FYI, I found a couple posts on oil in the throttle body on here but they are 10 years old and aren't related to a rollover, so I thought I'd start my own thread.
