2013 GMC Yukon Denail 6.2L Stuck Lifter

Yea, I took it out yesterday.  Apparently when I put it back in the new valley pan I didn't seal the threads.  I wrapped it with Teflon tape, put it back in, roughly clean the stuff under the car with brake cleaner and took it for about a mile test drive and had a little more oil pressure (was right below 40 from a cold start, now its right above 40) then let it sit overnight.  I checked this morning and it looks like there may have been a few drops from the front seal which I know about but not a stream like before in the middle of the truck.   I included pictures of what it look like around it before and after.  I'll take it on a longer drive later and make sure everything is good to go.  Now to figure out the front seal.  Baby steps! Haha
